The erection of Pelecanema n. g. (Nematoda: Spirurida: Acuariidae), with redescriptions of P. sirry (Khalil, 1931) n. comb. and P. pelecani (Johnston & Mawson, 1942) n. comb.

Pelecanema n. g. is erected for P. sirry (Khalil, 1931) n. comb., syn. Synhimantus sirry Khalil, 1931 (type-species) and P. pelecani (Johnston & Mawson, 1942) n. comb., syn. Dispharynx pelecani Johnston & Mawson, 1942. In the structure of its cordons, consisting of two rows of delicate cuticular plates, the new genus is similar to Synhimantus Railliet, Henry & Sisoff, 1912, Dispharynx Railliet, Henry & Sisoff, 1912, Chordatortilis Machado de Mendon?a & Olivera de Rodrigues, 1965 and Parachordatortilis Mutafchiev, Santoro & Georgiev, 2010. Pelecanema sirry, a parasite of Pelecanus onocrotalus L. and P. crispus Bruch (Pelecaniformes, Pelecanidae) in Africa (Egypt and Senegal) and Europe (Ukraine and Bulgaria), is redescribed using light and scanning electron microscopy on the basis of specimens from P. crispus from Bulgaria. Pelecanema pelecani, a parasite of Pelecanus conspicillatus Temminck in Australia, is also redescribed using light microscopy on the basis of specimens from its type-host and type-locality. In contrast to a previous opinion recognising Pelecanema sirry and P. pelecani as synonyms, the two species are considered distinct and P. pelecani is validated.     

Revision of the section Anillochlamys Jeannel, 1909 (Coleoptera: Leiodidae: Cholevinae: Leptodirini)

The taxonomy of the Iberian Leptodirini species of the section Anillochlamys Jeannel, 1909 has been revised. The proposed classification is based on the study of the genital structures of both sexes, in particular the internal sac of the aedeagus. According to the different models of internal sacs, the following genera, species and subspecies are identified: genus Anillochlamys Jeannel, 1909: A. aurouxi Español, 1965, A. bueni Jeannel, 1909 (= A. avariae Comas, 1977 n.syn.), A. cullelli Lagar, 1978, A. moroderi Bolívar, 1923 (= A. negrei Comas, 1990 n. syn.), A. subtruncatus Jeannel, 1930 (= A. baguenai Jeannel, 1930) and A. tropicus (Abeille, 1881) (= Adelops hispanicus Ehlers, 1893; A. tropicus var. apicalis Jeannel, 1909); genus Paranillochlamys Zariquiey, 1940: P. catalonicus (Jeannel, 1913), P. urgellesi (Español, 1965) and P. velox Zariquiey, 1940 (= P. velox montadai Lagar, 1963 n. syn.); genus Pseudochlamys Comas, 1977: P. raholai (Zariquiey, 1922) (= Anillochlamys raholai luis-bofilli Zariquiey, 1940 n. syn.); genus Spelaeochlamys Dieck, 1870 (= Typhlochlamys Español, 1975 n.syn.): S.bardisai (Español, 1975) (= Typhlochlamys escolai Comas, 1978 n. syn.), S. ehlersi Dieck, 1870 and S. ehlersi verai Comas, 1977 n. stat.     

"Slime molds" among the Tubulinea (Amoebozoa): molecular systematics and taxonomy of Copromyxa

Copromyxa protea is a dung-inhabiting amoeboid organism that aggregates to form simple macroscopic fruiting structures, sorocarps, which are composed of a single cell type. In a recent effort to find the phylogenetic positions of the less well-known sorocarpic protists considered to be "cellular slime molds," or aggregatively fruiting amoebae, we isolated C. protea and sequenced the nuclear-encoded small subunit ribosomal RNA gene from four samples collected from cattle farms in the central USA. Phylogenetic analyses of these data place C. protea in the eukaryotic supergroup Amoebozoa together with the Tubulinea, in which there has been no previous report of an aggregative fruiting habit. This is consistent with the morphology of the trophozoites. In fact, Copromyxa protea is found to be very closely related to Hartmannella cantabrigiensis and to a since lost amoeba isolate, Hartmannella sp. 4/3Da/10. This new grouping of Copromyxa+H. cantabrigiensis is sister to Glaeseria, which together are sister to the Amoebidae (Amoeba+Chaos). We suggest renaming, H. cantabrigiensis as C. cantabrigiensis and designate isolate 4/3Da/10 as C. protea. Future work is needed to see if these newly assigned members of the genus Copromyxa also show evidence of an ability to fruit.     

Phylogeny and genus-level classification of mantellid frogs (Amphibia, Anura)

We propose a novel classification of frogs in the family Mantellidae, based on published phylogenetic information and on a new analysis of molecular data. Our molecular tree for 53 mantellid species is based on 2419 base pairs of the mitochondrial 12S rRNA, 16S rRNA, tRNAVal and cytochrome b genes, and of the nuclear rhodopsin gene. Because the genus Mantidactylus Boulenger sensu lato is confirmed to be paraphyletic with respect to Mantella Boulenger, and is highly diverse in morphology and reproductive biology, we propose to partition Mantidactylus into seven genera by elevating four subgenera to genus rank (Blommersia Dubois, Guibemantis Dubois, Spinomantis Dubois, and Gephyromantis Methuen) and creating two new genera (Boehmantis gen. n. and Wakea gen. n.). In addition, we create the new subgenera Boophis (Sahona) subgen. n., Gephyromantis (Duboimantis) subgen. n., G. (Vatomantis) subgen. n., and Mantidactylus (Maitsomantis) subgen. n. The following species are transferred to Spinomantis, based on their phylogenetic relationships: S. elegans (Guibé) comb. n. (formerly in Mantidactylus subgenus Guibemantis); S. bertini (Guibé) comb. n. and S. guibei (Blommers-Schlösser) comb. n. (both formerly in Mantidactylus subgenus Blommersia); S. microtis (Guibé) comb. n. (formerly in Boophis Tschudi). Within Boophis, the new B. mandraka species group and B. albipunctatus species group are established. Boophis rhodoscelis (Boulenger) is transferred to the B. microtympanum group. The following five species are revalidated: Mantidactylus bellyi Mocquard and M. bourgati Guibé (not junior synonyms of M. curtus (Boulenger)); M. cowanii (Boulenger) (not syn. M. lugubris (Duméril)); M. delormei Angel (not syn. M. brevipalmatus Ahl); Mantella ebenaui (Boettger) (not syn. M. betsileo (Grandidier)). The new classification accounts for recent progress in the understanding of the phylogeny and natural history of these frogs, but it is still tentative for a number of species. Future modifications may be necessary, especially as concerns species now included in Gephyromantis and Spinomantis.Full article published online at: http://www.senckenberg.de/odes/06-11.htm     

A taxonomic revision of Labiostrongylus (Labiostrongylus) (Yorke & Maplestone, 1926) and Labiostrongylus (Labiomultiplex) n. subg. (Nematoda: Cloacinidae) from macropodid and potoroid marsupials

The morphological characters used to differentiate species in the genus Labiostrongylus Yorke & Maplestone, 1926, parasitic in macropodid and potoroid marsupials, are discussed. The genus is divided into three subgenera Labiostrongylus (Labiostrongylus), L. (Labiomultiplex) n. subg. and L. (Labiosimplex) n. subg. on the basis of the presence or absence of interlabia and the morphology of the oesophagus. A key to the subgenera is given and a detailed revision of two of the subgenera is presented. Keys to each of the subgenera are given, the species discussed being: L. (L.) labiostrongylus) (type-species) (syn. L. (L.) insularis, L. (L.) grandis, L. (L.) macropodis sp. inq. and L. (L.) nabarlekensis n. sp., in the subgenus Labiostrongylus, and L. (Lm.) eugenii, L. (Lm.) novaeguineae, L. (Lm.) onychogale, L. (Lm.) uncinatus, L. (Lm.) billardierii n. sp., L. (Lm.) constrictis n. sp., L. (Lm.) kimberleyensis n. sp., L. (Lm.) thylogale n. sp., and L. (Lm.) potoroi, n. sp., in the subgenus Labiomultiplex.     

Mealybugs of the genus <Emphasis Type="Italic">Dysmicoccus</Emphasis> Ferris (Homoptera,Pseudococcidae) of the fauna of Russia and adjacent countries

A key to six species of the genus Dysmicoccus from the former USSR is given, provided with comprehensive information on the nomenclature, morphology, and taxonomy of the widely variable D. walkeri. The following new synonymies are established: D. walkeri Newstead (= D. kazanskyi Borchs., syn. n.; = glandularis Baz., syn. n.; = badachshanicus Nurm., syn. n.; = innermongolicus Tang in Tang and Li, syn. n.). Lectotype of D. kazanskyi is designated. Dysmicoccus multivorus (Kir.) is considered in the revision of the genus Trionymus Berg (Danzig, 1997), the rest species are discussed in the monograph of the Far Eastern fauna (Danzig, 1980).     

Phylogeny and biogeography of Thyridosmylus (Neuroptera: Osmylidae)

The first phylogenetic analysis of the genus Thyridosmylus Krüger is presented. All species from China were scored in a morphological analysis, along with extralimital species from India (Thyridosmylus pustulatus Kimmins) and Madagascar (Thyridosmylus marmoratus Fraser), and were compared with out‐group exemplars from Spilosmylus Kolbe, Thaumatosmylus Krüger and Osmylus Latreille. A monophyletic Thyridosmylus sister to Spilosmylus is confirmed based on this analysis, with the Malagasy Thyridosmylus marmoratus as sister to the Oriental Thyridosmylus species. Based on the results of this analysis, the biogeography of world Thyridosmylus is discussed. It is proposed that the genus originated in Gondwana no later than the Late Cretaceous (88 Ma) before the break‐up of the Madagascar–India continent. A new species, Thyridosmylus paralangii sp.n., is described from Guangxi Province, whereas two species [Thyridosmylus langii (McLachlan) and Thyridosmylus perspicillaris minor Kimmins] are recorded from China for the first time. Four synonyms are identified: Thyridosmylus laetus Yang et al. syn.n. , Thyridosmylus similaminor Yang syn.n. , Thyridosmylus vulgatus Yang syn.n. and Thyridosmylus mimoroides Yang syn.n. A key to the species of the world is provided.     

Revision and phylogeny of Syrphetodes (Coleoptera: Ulodidae): implications for biogeography,alpinization and conservation

The genus Syrphetodes Broun is revised to include a total of 13 species. Most of the species are restricted in their distributions, are rarely collected and have been attributed conservation status in New Zealand. Eleven species are described as new: three from Northland (S. relictus sp.n ., Te Paki; S. insularis sp.n. , Three Kings Islands; S. magnus sp.n. , Hokianga), one from the central North Island (S. obtusus sp.n. ), one from Central Otago (S. nunni sp.n. , Waikaia Bush), and seven from the southern Alps (S. cirrhopogon sp.n. , Aspiring National Park; S. occiduus sp.n. , Westland; S. melanopogon sp.n. , Mt Dewar, Paparoa Range; S. defectus sp.n. , northern Paparoa Range; S. marrisi sp.n. , Mt Domett, Northwest Nelson; S. carinatus sp.n. , Victoria Range). Eleven synonymies are proposed: S. crenatus Broun (= S. dorsalis Broun, syn.n .), S. marginatus Pascoe (= S. bullatus Sharp, syn.n. ; S. sylvius Broun, syn.n. ; S. cordipennis Broun, syn.n. ; S. punctatus Broun, syn.n. ; S. simplex Broun, syn.n. ; S. nodosalis Broun, syn.n. ; S. truncatus Broun, syn.n. ; S. variegatus Broun, syn.n. ; S. pensus Broun, syn.n. ; S. thoracicus Broun, syn.n. ). The phylogenetic relationships among the species were reconstructed using morphological (25 adult characters) and DNA sequence (nuclear 28S rDNA and mitochondrial cytochrome c oxidase subunit I) data. A morphological analysis rooted with Trachyderastes resulted in a split between lowland and high‐altitude species and a well‐supported group from Northland. Molecular trees rooted with representatives of Trachyderastes Kaszab (New Caledonia), Meryx Latrielle (Australia), Ulodes Erichson (Australia) and three New Zealand genera (Arthopus Sharp, Brouniphylax Strand, Exohadrus Broun) resulted in the following tree: ((Ulodes, Brouniphylax) (Exohadrus, Arthopus)) (Syrphetodes (Meryx, Trachyderastes)). Species relationships within Syrphetodes included a strongly supported northern North Island clade and an alpine clade either as sister taxon to S. crenatus and S. marginatus or sister remaining lowland lineages. Combined phylogenetic analyses also showed paritial congruence with separate partitions. The distributions of the lowland species, in particular those from the North Island, correspond to islands that existed in the Pliocene. The alpine, black‐coloured lineage, found above the treeline, is monophyletic based on several characters (e.g. lack of abdominal flanges and reduced scalation) and, in some reconstructions, the tan‐coloured S. cirrhopogon is sister taxon to the remaining black‐coloured species. This published work has been registered in ZooBank, http://zoobank.org/urn:lsid:zoobank.org:pub:697E68E8‐EE90‐46C1‐A009‐78A794E0EF4F .     

A taxonomic and morphological review of the genus Cania Walker, 1855 (Lepidoptera,Limacodidae)

Based on a complex study of morphology of adults, male and female genitalia, functional musculature of male genitalia, and molecular characters, three subgenera were distinguished in the genus Cania: the nominative one, Paracania Solovyev subgen. n. (type species Neaera bilinea Walker, 1855), and Minicania Solovyev subgen. n. (type species C. minuta Holloway, 1986). The genus Cania presently includes 21 species, two of which are described as new ones: C. (Paracania) lourensi Solovyev sp. n. (Philippines: Luzon, Negros, Panay) and C. (Minicania) kitchingi Solovyev sp. n. (Thailand). New synonymies are established: C. bilinea (Walker, 1855) = C. polyhelixa Wu et Fang, 2009 syn. n. and C. robusta Hering, 1931 = C. pseudobilinea Wu et Fang, 2009 syn. n.     

The high‐Andean Jivarus Giglio‐Tos (Orthoptera,Acridoidea, Melanoplinae): systematics,phylogenetic and biogeographic considerations

The high‐Andean genus Jivarus Giglio‐Tos from Ecuador, Colombia and Peru is revised. Morphological cladistic analysis indicated that Jivarus montanus and the new species digiticercus sp.n. and rugosus sp.n. must be treated as a separate genus, Maylasacris gen.n. The remaining species included in the analysis are assigned to the genus Jivarus, for which the following six species groups are identified: americanus group, antisanae group, carbonelli group, cohni group, pictifrons group and jagoi group. Twenty‐nine species are recognized for Jivarus, with ten described as new: J. rectus sp.n. , J. megacercus sp.n. , J. spatulus sp . n. , J. auriculus sp.n. , J. riveti sp.n. , J. sphaericus sp.n. , J. discoloris sp . n. , J. profundus sp.n. , J. ronderosi sp.n. and J. guarandaensis sp.n. The following new synonymies are proposed: Jivarus albolineatus Ronderos with J. antisanae (Bolivar) syn.n. , J. cerdai Ronderos and J. osunai Ronderos with J. alienus (Walker) syn.n. , and J. rubriventris Ronderos with J. ecuadorica (Hebard) syn.n. ; the new combinations Jivarus ecuadorica (Ronderos) comb.n. and Maylasacris montanus (Ronderos) comb.n. are proposed. Keys to the species of the genera and a review of the morphological characters defining the taxa are provided. Patterns of distribution of the clades coincide with the geography of the northern Andes of Colombia and Ecuador. Areas of endemism of the Jivarus species groups and Maylasacris are delimited by both the high‐altitude curves, including transverse zones, and the drier climates of the intra‐Andean valleys, clearly indicating recent, post‐glacial palaeogeography, as shown also in vegetation distributions. This paper has been formatted with many embedded links to images of type and paratype specimens, maps based on geo‐referenced specimen data and species keys available on the Orthoptera Species file online ( http://orthoptera.speciesfile.org ).     

Putting Parasemia in its phylogenetic place: a molecular analysis of the subtribe Arctiina (Lepidoptera)

Despite being popular among amateur and professional lepidopterologists and posing great opportunities for evolutionary research, the phylogenetic relationships of tiger moths (Erebidae: Arctiinae) are not well resolved. Here we provide the first phylogenetic hypothesis for the subtribe Arctiina with the basic aim of clarifying the phylogenetic position of the Wood Tiger Moth Parasemia plantaginis Hübner, a model species in evolutionary ecology. We sampled 89 species in 52 genera within Arctiina s.l., 11 species of Callimorphina and two outgroup species. We sequenced up to seven nuclear genes (CAD, GAPDH, IDH, MDH, Ef1α, RpS5, Wingless) and one mitochondrial gene (COI) including the barcode region (a total of 5915 bp). Both maximum likelihood and Bayesian inference resulted in a well‐resolved phylogenetic hypothesis, consisting of four clades within Arctiina s.s. and a clade comprising spilosomine species in addition to Callimorphina and outgroups. Based on our results, we present a new classification, where we consider the Diacrisia clade, Chelis clade, Apantesis clade, Micrarctia Seitz and Arctia clade as valid genera within Arctiina s.s., whereas Rhyparia Hübner syn.n. and Rhyparioides Butler syn.n. are synonymized with Diacrisia Hübner; Neoarctia Neumoegen & Dyar syn.n. , Tancrea Püngeler syn.n. , Hyperborea Grum‐Grshimailo syn.n. , Palearctia Ferguson syn.n. , Holoarctia Ferguson syn.n. , Sibirarctia Dubatolov syn.n. and Centrarctia Dubatolov syn.n. are synonymized with Chelis Rambur; Grammia Rambur syn.n. , Orodemnias Wallengren syn.n. , Mimarctia Neumoegen & Dyar syn.n. , Notarctia Smith syn.n. and Holarctia Smith syn.n. are synonymized with Apantesis Walker; and Epicallia Hübner syn.n. , Eucharia Hübner syn.n. , Hyphoraia Hübner syn.n. , Parasemia Hübner syn.n. , Pericallia Hübner syn.n. , Nemeophila Stephens syn.n. , Ammobiota Wallengren syn.n. , Platarctia Packard syn.n. , Chionophila Guenée syn.n. , Eupsychoma Grote syn.n. , Gonerda Moore syn.n. , Platyprepia Dyar syn.n. , Preparctia Hampson syn.n. , Oroncus Seitz syn.n. , Acerbia Sotavalta syn.n. , Pararctia Sotavalta syn.n. , Borearctia Dubatolov syn.n. , Sinoarctia Dubatolov syn.n. and Atlantarctia Dubatolov syn.n. are synonymized with Arctia Schrank, leading to 33 new genus‐level synonymies. Our focal species Arctia plantaginis comb.n. is placed as sister to Arctia festiva comb.n. , another widespread aposematic species showing wing pattern variation. Our molecular hypothesis can be used as a basis when adding more species to the tree and tackling interesting evolutionary questions, such as the evolution of warning signalling and mimicry in tiger moths.     

Systematics and cladistics of Megalostomis Chevrolat,and the biogeography of Clytrini (Coleoptera: Cryptocephalinae)

We present a cladistic analysis of the subtribe Megalostomina, a Neotropical group of ‘case‐bearer’ leaf beetles. A comparative study of the external and internal adult morphology of Clytrini was undertaken. New characters are described for the subtribe Megalostomina, from the internal sac of aedeagus, which provide a useful phylogenetic signal. More than 180 photographs illustrating the most important characters (74 characters and their respective states) used in the cladistic analysis are provided. The cladistic analysis of 57 terminal taxa and 95 characters was undertaken, under equal weights, and also using implied weights as a means to down‐weight homoplasious characters. We test the monophyly and explore intergeneric relationships of the subtribe Megalostomina, and reconstruct the relationships among the species of Megalostomis Chevrolat. The 42 species recognized can be assigned either to a group mostly containing species of North and Central America, or to a larger one of mostly South American species. Support is low, and the formal naming of groups is deferred pending a revision of all Megalostomina. We confirm the subgenera of Megalostomis of previous classifications are unnatural, and the following changes in the generic classification of the subtribe Megalostomina are proposed: Coleorozena Moldenke syn.n. of Coscinoptera Lacordaire; Coleothorpa Moldenke syn.n. of Coscinoptera Lacordaire; and Euryscopa (Coleoguerina) Moldenke syn.n. of Coscinoptera Lacordaire. Furthermore, six formerly recognized subgenera of Megalostomis are considered junior synonyms of Megalostomis Chevrolat: Megalostomis (Minturnia) Lacordaire syn.n. ; Megalostomis (Heterostomis) Lacordaire syn.n. ; Megalostomis (Scaphigenia) Lacordaire syn.n. ; Megalostomis (Snellingia) Moldenke syn.n. ; Megalostomis (Coleobyersa) Moldenke syn.n. ; and Megalostomis (Pygidiocarina) Moldenke syn.n. Thus, no subgenera are recognized within Megalostomis. Previous hypotheses on Clytrini biogeography were revisited in the light of new biogeographic and phylogenetic knowledge. We hypothesize an origin of Clytrini in tropical/subtropical Gondwana, when South America, Africa, Madagascar and India were connected. Changes in the configuration of the tectonic plates in the Cenozoic allowed the dispersal of Clytrina to the Palaearctic and Nearctic regions, and dispersion of Babiina and Megalostomina through the Nearctic region.     

Comprehensive phylogeny of the Cleroidea (Coleoptera: Cucujiformia)

The first thorough molecular phylogeny of the superfamily Cleroidea, represented by 377 taxa, and the first with an emphasis on Trogossitidae, was undertaken. Maximum likelihood and Bayesian analyses were performed on a four‐gene dataset (18S, 28S, cox1, cytb) of 395 taxa (along with 18 outgroups), including all 16 currently recognized families of Cleroidea and all current and formerly recognized tribes of Trogossitidae. The superfamily as a whole received strong support in Bayesian analyses. On the basis of phylogenetic results, 18 families in Cleroidea are recognized, including three taxa elevated to family for the first time and two reinstated families. The former tribe Rentoniini (Trogossitidae: Peltinae) was strongly supported as a monophyletic group apart from the remainder of Trogossitidae, and is herein elevated to family status, Rentoniidae stat.n. Protopeltis was also found to be an isolated lineage and becomes Protopeltidae stat.n. Peltini + Larinotini were recovered as a weakly supported sister grouping; Peltini (including only Peltis) becomes Peltidae stat.rest. The trogossitid subfamily Lophocaterinae, to the exclusion of Decamerini, formed a clade which is here designated Lophocateridae stat.rest. and sensu n. The Trogossitinae tribes Calityini, Egoliini (represented by Egolia) and Larinotini were recovered apart from core Trogossitidae but showed no strong affinities to other taxa or congruence between analyses; they are here conservatively retained in Trogossitidae as Calityinae stat.rest. , Egoliinae stat.rest. and Larinotinae stat.rest. The genus Thymalus of the peltine tribe Thymalini was indicated with moderate to strong support as the sister group of the Decamerini (Trogossitidae: Lophocaterinae); together these represent Thymalidae stat.n. and sensu n. with subfamilies Decamerinae stat.rest. ( new placement ) and Thymalinae stat.n. The remainder of Trogossitinae, the tribes Trogossitini and Gymnochilini, formed a well‐supported clade which comprises the Trogossitidae: Trogossitinae sensu n. The tribe Gymnochilini syn.n. is synonymized with Trogossitini. The monotypic family Phloiophilidae was recovered, contradicting a recent placement within Trogossitidae. The melyrid lineage was recovered with moderate (maximum likelihood) to strong (Bayesian analyses) support and includes the families Phycosecidae, Rhadalidae, Mauroniscidae, Prionoceridae and Melyridae (including Dasytidae and Malachiidae). The genus Dasyrhadus is tentatively transferred from Rhadalidae to Mauroniscidae. The genus Gietella, once proposed as a distinct family but recently placed within Dasytidae, was recovered as strongly sister to Rhadalidae sensu n. , and we transfer it to that family as Gietellinae new placement . Attalomiminae (formerly Attalomimidae) syn.n. is synonymized with Melyridae: Malachiinae: Lemphini sensu n. Melyridae sensu n. includes only Dasytinae, Malachiinae and Melyrinae. Metaxina is returned to the Chaetosomatidae sensu n. , of which Metaxinidae syn.n. becomes a junior synonym. Resolution within Cleridae was generally poor, but a broadly defined Korynetinae stat rest. + Epiclininae received high support (Bayesian analyses). Outside of Trogossitidae, the main focus of this study, major rearrangements of the classification of Cleroidea were not undertaken, despite evidence indicating such changes are needed.     

The cladistics and higher classification of the Pimpliformes (Hymenoptera: Ichneumonidae)

The monophyly of the ichneumonid clade Pimpliformes is established and the phylogenetic relationships of the eight component subfamilies are resolved. The clade (Acaenitinae + (Diacritinae + (Cylloceriinae + (Diplazontinae + Orthocentrinae)))) is the sister-lineage to the clade (Pimplinae + (Rhyssinae + Poemeniinae)). The Nearctic genus Cressonia Dasch is transferred to the Diacritinae from the Orthocentrinae. Tribes are not recognized in the Acaenitinae as the Coleocentrini (sensu Townes, 1971) is paraphyletic with respect to the Acaenitini. The Cylloceriinae is recognized as comprising three genera, Cylloceria Schiødte, Allomacrus Förster and Sweaterella gen.n. The Orthocentrinae, including the Helictinae of authors, is shown to be monophyletic, but the latter is clearly shown to be paraphyletic if the Orthocentrus genus-group is excluded. The Pimplinae comprises four monophyletic tribes: the Delomeristini, consisting of Delomerista Förster and Atractogaster Kriechbaumer; the Perithoini trib.n., which includes only Perithous Holmgren (= Hybomischos Baltazar syn.n.); the Pimplini, which includes the Theronia genus-group as well as the Pimpla genus-group; and the Ephialtini, which includes the Polysphinctini syn.n., a monophyletic group that previously rendered the restricted Ephialtini paraphyletic. The tribe Delomeristini is the sister-group to the clade (Ephialtini + (Perithoini + Pimplini)). The subfamily Poemeniinae is recognized as comprising three tribes: the Pseudorhyssini (trib.n.) which includes the single Holarctic genus Pseudorhyssa Merrill; the Rodrigamini (trib.n.) which includes only the Costa Rican genus Rodrigama Gauld; and the Poemeniini. The tribe Pseudorhyssini is the sister-group to the clade (Rodrigamini + Poemeniini). The phylogenetic inter-relationships of the genera of Poemeniini are resolved. A new genus from South Africa, Guptella (gen.n.) is described, and Achorocephalus Kriechbaumer is shown to be a synonym of Eugalta Cameron (syn.n.). The evolution of biological traits within the Pimpliformes is discussed with reference to the elucidated phylogeny, and zoogeographic patterns are outlined.     

Tales of dracula ants: the evolutionary history of the ant subfamily Amblyoponinae (Hymenoptera: Formicidae)

The ants in the subfamily Amblyoponinae are an old, relictual group with an unusual suite of morphological and behavioural features. Adult workers pierce the integument of their larvae to imbibe haemolymph, earning them the vernacular name ‘dracula ants’. We investigate the phylogeny of this group with a data set based on 54 ingroup taxa, 23 outgroups and 11 nuclear gene fragments (7.4 kb). We find that the genus Opamyrma has been misplaced in this subfamily: it is a member of the leptanilline clade and sister to all other extant Leptanillinae. Transfer of Opamyrma to Leptanillinae renders the Amblyoponinae monophyletic. The enigmatic Afrotropical genus Apomyrma is sister to all other amblyoponines, and the latter cleave into two distinct and well‐supported clades, here termed POA and XMMAS. The POA clade, containing Prionopelta, Onychomyrmex and Amblyopone, is well resolved internally, and its structure supports synonymy of the genus Concoctio under Prionopelta ( syn.n. ). The XMMAS clade comprises two well‐supported groups: (i) a predominantly Neotropical clade, for which we resurrect the genus name Fulakora ( stat.r., stat.n. ), with junior synonyms Paraprionopelta ( syn.n. ) and Ericapelta ( syn.n. ); and (ii) the remaining taxa, or ‘core XMMAS’, which are manifested in our study as a poorly resolved bush of about a dozen lineages, suggesting rapid radiation at the time of their origin. Most of these XMMAS lineages have been assigned to the catch‐all genus Stigmatomma, but the more distinctive elements have been treated as separate genera (Xymmer, Mystrium, Myopopone and Adetomyrma). Resolution of basal relationships in the core XMMAS clade and reconfiguration of ‘Stigmatomma’ to restore monophyly of all named genera will require more extensive genetic data and additional morphological analysis. However, the genus Bannapone can be synonymized under Stigmatomma ( syn.n. ) because it is embedded within a clade that contains S. denticulatum, the type species of Stigmatomma. Divergence dating analysis indicates that crown Amblyoponinae arose in the mid‐Cretaceous, about 107 Ma (95% highest probability density: 93–121 Ma). The POA and XMMAS clades have estimated crown ages of 47 and 73 Ma, respectively. The initial burst of diversification in the core XMMAS clade occurred in the Late Paleocene/Early Eocene (50–60 Ma). Ancestral range reconstruction suggests that amblyoponines originated in the Afrotropics, and dispersed to the Indo‐Malayan region and to the New World. During none of these dispersal events did the ants break out of their cryptobiotic lifestyle.     

Description of Phaeobola aeris gen. nov., sp. nov (Rhizaria,Cercozoa, Euglyphida) Sheds Light on Euglyphida’s Dark Matter

The majority of Euglyphida species are characterised by shells with imbricated silica scales. Environmental surveys indicate a large unexplored diversity and recent efforts hinted at a certain diversity of yet undescribed, inconspicuous, scale-lacking Euglyphida. Here we describe Phaeobola aeris gen. nov., sp. nov. that shows a variety of morphological characters typical for the Euglyphida but lacks silica scales-instead, this species bears an agglutinated test. Neither its morphology nor phylogenetic placement allows its assignment to any currently described family. We erected the yet monospecific genus Phaeobola gen. nov., which with yet available data remain Euglyphida incertae sedis.     

860. BOMAREA × CANTABRIGIENSIS

Bomarea ×cantabrigiensis Chitt. is a seldom grown, twining hybrid which was raised at Cambridge University Botanic Garden. The origin of the hybrid is discussed along with the taxonomic history of the genus and the parents.     

Phylogenetic relationships of Acronictinae with discussion of the abdominal courtship brush in Noctuidae (Lepidoptera)

We present results of an eight‐gene molecular study of the subfamily Acronictinae and related Noctuidae. Amphipyrinae are recovered as sister to Acronictinae, but with weak support – not surprisingly, the content of the two subfamilies has often been mixed in classifications. Balsinae, previously placed near Acronictinae or within Noctuinae, is recovered within an unresolved polytomy of Cuculliinae, Eustrotiinae, Raphiinae and Dilobinae. Gerbathodes Warren, Moma Hübner and Nacna Fletcher are excluded from Acronictinae. Three genera recently transferred into the subfamily – Cerma Hübner, Chloronycta Schmidt & Anweiler and Comachara Franclemont – are confirmed as acronictines. Lophonycta Sugi (the type genus of Lophonyctinae) is returned to the Acronictinae. Sinocharis Püngeler, formerly considered to be Acontiinae or as the basis of its own subfamily Sinocharinae, is nested within early diverging Acronictinae genera. Both subfamilies are formally synonymized: i.e. Lophonyctinae syn.n. and Sinocharinae syn.n. Nine acronictine genus‐level taxa were found to nest within the nominate genus Acronicta Ochsenheimer: Eogena Guenée, Hyboma Hübner, Hylonycta Sugi, Jocheaera Hübner, Oxicesta Hübner, Simyra Ochsenheimer, Subacronicta Kozhanchikov, Triaena Hübner, and Viminia Chapman. Eogena, Oxicesta, and Simyra, currently treated as valid genera, nest within terminal clades of the genus Acronicta and are here subsumed within the genus: Eogena syn.n. , Oxicesta syn.n. and Simyra syn.n. Four well‐supported species groups within Acronicta are identified: the alni clade, the leporina clade, the nervosa clade and the psi clade. While many previous treatments have stated explicitly that Acronictinae lack abdominal scent brushes, or excluded genera with brushes from the subfamily, we show that well‐developed brushes are present in three early diverging acronictine genera: Cerma, Lophonycta, and Sinocharis. We illustrate and describe the brushes of all three genera, and briefly review the taxonomic distribution of the anterior abdominal courtship brushes in Noctuidae, emphasizing the labile evolutionary distribution of these structures.
