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.     

Revision of the genus Helastia sensu stricto with description of a new genus (Lepidoptera: Geometridae: Larentiinae)

Abstract

Helastia Guenée, 1868 is redefined and redescribed. New Zealand species previously placed in that genus but not congeneric with the type species are reassigned to either the available genera Epyaxa Meyrick, 1883, Asaphodes Meyrick, 1885 and Xanthorhoe Hübner, [1825] or placed in a newly described genus, Gingidiobora. Six Australian species placed in Xanthorhoe are shown to be congeneric with three New Zealand species, previously placed in Helastia and here transferred to Epyaxa.

Eight new species are described in Helastia: Helastia alba n. sp.; H. angusta n. sp.; H. christinae n. sp.; H. cryptica n. sp.; H. mutabilis n. sp.; H. ohauensis n. sp.; H. salmoni n. sp.; H. scissa n. sp. The following new combinations and synonymies are proposed: Asaphodes chlorocapna (Meyrick, 1925) n. comb.; A. citroena (Clark, 1934) n. comb.; A. glaciata (Hudson, 1925) n. comb.; A. ida (Clark, 1926) n. comb; Epyaxa agelasta (Turner, 1904) n. comb.; E. centroneura (Meyrick, 1890) n. comb.;

E. epia (Turner, 1922) n. comb.; E. hyperythra (Lower, 1892) n. comb.; E. lucidata (Walker, 1862) n. comb.; E. sodaliata (Walker, 1862) n. comb.; E. subidaria (Guenée, 1857) n. comb.; E. venipunctata (Walker, 1863) n. comb.; Gingidiobora nebulosa (Philpott, 1917) n. comb.; G. subobscurata (Walker, 1862) n. comb.; Helastia clandestina (Philpott, 1921) n. comb.; H. corcularia (Guenée, 1868) n. comb. (= Larentia infantaria Guenée, 1868 n. syn.); H. expolita (Philpott, 1917) n. comb.; H. siris (Hawthorne, 1897) n. comb.; H. triphragma (Meyrick, 1883) n. comb.     

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.     

Generic revision and phylogeny of Microweiseinae (Coleoptera: Coccinellidae)

The monophyly and phylogenetic relationships of the subfamily Microweiseinae were investigated. Twenty‐three in‐group taxa, representing all known genera of Microweiseinae (except for Microcapillata Gordon) were included in a cladistic analysis, based on 45 adult morphological characters. The parsimony analysis of the resulting data matrix supported the monophyly of Microweiseinae, Carinodulini, Serangiini and Microweiseini (inclusive of Sukunahikonini). The recognition of Sukunahikonini renders Microweiseini paraphyletic, and consequently both tribes were synonymized, retaining Microweiseini as a senior family‐group name ( syn.n. ). Genera and tribes of Microweiseinae are diagnosed thoroughly, illustrated and keys to their identification are provided. The following nomenclatural changes were made: Hikonasukuna Sasaji and Orculus Sicard are synonymized with Scymnomorphus Weise ( syn.n. ); Gnathoweisea Gordon is synonymized with Microweisea Cockerell ( syn.n. ); Hikonasukuna monticola Sasaji and Orculus castaneus Sicard are transferred to Scymnomorphus ( comb.n. ); Smilia planiceps Casey, Gnathoweisea hageni Gordon, Gnathoweisea ferox Gordon, Gnathoweisea micula Gordon and Gnathoweisea texana Gordon are transferred to Microweisea ( comb.n ). Three new genera are described: Allenius gen.n. for Allenius californianus sp.n. (type species) from Mexico and Allenius iviei sp.n. from U.S.A.; Gordoneus gen.n. (type species Gnathoweisea schwarzi Gordon from U.S.A.); and Cathedrana gen.n. (type species Cathedrana natalensis sp.n. from South Africa). The first African member of Carinodulini, Carinodulina ruwenzorii sp.n. is described. The genera Microweisea, Coccidophilus, Serangium and Delphastus are well‐known predators of sternorrynchous Hemiptera, such as scale insects (Diaspididae) and whiteflies (Aleyrodidae), and play a significant role in agricultural ecosystems as biocontrol agents. Host data and biological records are summarized for each genus.     

Phylogeny,character evolution and tribal classification in Crambinae and Scopariinae (Lepidoptera,Crambidae)

Crambinae (2047 spp.) and Scopariinae (577 spp.) are two major groups of pyraloid moths with a worldwide distribution. Their larvae feed predominantly on Poales and Bryophyta, with many cereal crop pests. We present the first molecular phylogeny of the two groups based on five nuclear genes and one mitochondrial gene (total = 4713 bp) sampled for 58 crambine species representing 56 genera and all tribes, 33 scopariine species representing 12 genera, and species in several other crambid lineages. Maximum likelihood and Bayesian analyses of the molecular data resolve suprageneric relationships in Crambinae and Scopariinae, whereas relationships between these and other subfamilies remain ambiguous. Crambinae and Scopariinae are each recovered as monophyletic groups, and Erupini, formerly regarded as an ingroup of Midilinae, is recovered as a possible sister group of Crambinae. The tree topology suggests the following two major changes within Crambinae: Prionapterygini Landry syn.n. of Ancylolomiini Ragonot stat. rev. and Myelobiini Minet syn.n. of Chiloini Heinemann. Argyriini Munroe is monophyletic after the transfer of Pseudocatharylla Bleszynski and Vaxi Bleszynski to Calamotrophini. Crambini, Diptychophorini and Haimbachiini are monophyletic after the exclusion of Ancylolomia Hübner, Euchromius Guenée, Micrelephas Dognin and Miyakea Marumo from Crambini, as well as Microchilo Okano from Diptychophorini. Euchromiini tribe n. is described for Euchromius. Microcramboides Bleszynski syn.n. and Tortriculladia Bleszynski syn.n. are synonymized with Microcrambus Bleszynski. In Scopariinae, Caradjaina Leraut syn.n. and Cholius Guenée syn.n. are synonymized with Scoparia Haworth, and, in addition, Dasyscopa Meyrick syn.n. , Dipleurinodes Leraut syn.n. and Eudipleurina Leraut syn.n. are synonymized with Eudonia Billberg. Micraglossa melanoxantha (Turner) (Scoparia) comb.n. is proposed as a new combination. We analysed 27 morphological characters of wing venation, tympanal organs, male and female genitalia, as well as host plant data and egg‐laying behaviour. The ancestral character‐state reconstructions confirmed previous apomorphies and highlighted new apomorphies for some of the newly recovered clades. The derived, nonadhesive egg‐dropping behaviour is found to have evolved at least twice in Crambinae and is associated with the use of Pooideae as host plants.

The genus Antillothrips Stannard, with descriptions of two new species (Thysanoptera: Phlaeothripidae)

Abstract. The genus Antillothrips Stannard ( Elatea Faure, syn.n.) is redefined with a key to the ten species: australis sp.n.; exastis (Ananthakrishnan & Kudo) stat.n. comb.n.; cingulatus (Hood) (= Haplothrips (Hindsiana) sakimurai Moulton syn.n.; Xenothrips opacus Ananthakrishnan & Kudo syn.n.); graminellus Ananthakrishnan & Jagadish; hartwigi sp.n.; malabaricus (Ananthakrishnan); micropterus Pitkin; nayari (Ananthakrishnan); stannmdi (Faure) comb.n.; varius (Ananthakrishnan & Jagadish). Lectotypes are designated for opacus and exastis.     

Reassessment of Paleotachina Townsend and Electrotachina Townsend and their removal from?the?Tachinidae (Diptera)

The monotypic genera Paleotachina Townsend, 1921 and Electrotachina Townsend, 1938 were originally described as fossils in amber but were later discovered to be inclusions in copal. Both taxa were originally assigned to the Tachinidae (Diptera) and this placement has continued to the present day. The holotypes of the two type species, P. smithii Townsend and E. smithii Townsend, were examined and the following taxonomic and nomenclatural changes are proposed: Paleotachina is transferred to the Muscidae and placed in synonymy with Aethiopomyia Malloch, 1921, syn. n.; P. smithii Townsend, type species of Paleotachina, is synonymized with Aethiopomyia gigas (Stein, 1906), syn. n.; Electrotachina is transferred to the Sarcophagidae and placed in synonymy with Dolichotachina Villeneuve, 1913, syn. n.; E. smithii Townsend, type species of Electrotachina, is recognized as a valid species of Dolichotachina comb. n. Images of the holotypes of P. smithii and E. smithii are provided and features that have helped place these copal inclusions in their new combinations are discussed.     

Molecular phylogeny,larval case architecture,host–plant associations and classification of European Coleophoridae (Lepidoptera)

Bauer, F., Stübner, A., Neinhuis, C. & Nuss, M. (2012). Molecular phylogeny, larval case architecture, host–plant associations and classification of European Coleophoridae (Lepidoptera). —Zoologica Scripta, 41, 248–265. Several attempts based on adult morphology have aimed at classifying the megadiverse Coleophoridae, either by defining species groups or by splitting the large genus Coleophora into many smaller genera. A previous cladistic analysis focussing on larvae suggests monophyly of some case type groups as well as host–plant associations with a preference for certain plant tissues and growth forms. Here, a first molecular phylogeny for Coleophoridae is presented to test these partly contradicting hypotheses. Bayesian statistics is applied to different partitioning strategies of a COI + wingless data set (1815 bp) for 105 European species, revealing eight monophyletic species groups. A broader defined Coleophora with internal groups is better supported than the division into many genera. Goniodoma Zeller, 1849 syn. rev. and Metriotes Herrich‐Schäffer, 1853 syn. n. are nested within Coleophora Hübner, 1822. Seven species are transferred to Coleophora: C. auroguttella ( Zeller, 1849 ) comb. rev., C. limoniella Stainton, 1884 comb. rev., C. millierella (Ragonot, 1882) comb. n., C. nemesi (C?pu?e, 1970) comb. n., C. sinica (Li & Zheng, 2002) comb. n. (from Goniodoma) as well as C. jaeckhi (Baldizzone, 1985) comb. n. and C. lutarea (Haworth, 1828) comb. n. (from Metriotes). None of the formerly suggested case types is synapomorphic for any of the recovered clades. In contrast, cases built from glossy silk that turns black or dark brown is synapomorphic for the vibicella group. Some clades have radiated on certain plant taxa along with a specialisation in specific tissues, for example, the clade containing the saturatella (leaf miners) and frischella (seed miners) groups is associated with Fabaceae, the albella group (seed miners) with Caryophyllales and the serpylletorum group (leaf miners) with Lamiaceae. Calculating an index of host specificity for all studied species confirms significant differences between seed and leaf feeders on herbaceous plants, but not between leaf feeders on herbaceous and woody plants.     

The millipede family Polydesmidae in Taiwan, with descriptions of five new species (Polydesmida, Diplopoda)

Polydesmidae are represented in Taiwan by seven species in two genera. Neither of the genera is endemic to Taiwan, but six of the species are, including five new: Nipponesmus minorsp. n., Epanerchodus bispinosussp. n., Epanerchodus curtigonopussp. n., Epanerchodus flagellifersp. n. and Epanerchodus pinguissp. n. In addition, the diagnosis of the hitherto enigmatic genus Nipponesmus Chamberlin & Wang, 1953 is refined vis-à-vis the especially similar, Central Asian, Siberian and Eastern European genus Schizoturanius Verhoeff, 1931, chiefly based on new material of the type-species Nipponesmus shirinensis Chamberlin & Wang, 1953; this species is adequately redescribed and represents still another Taiwanese endemic. A key to all three currently known species of Nipponesmus Chamberlin & Wang, 1953 is given. The highly speciose Central to East Asian genus Epanerchodus Attems, 1901 is represented in Taiwan by five species, all keyed, including Epanerchodus orientalis Attems, 1901, which is long known to be highly variable in Japan and found particularly polymorphous and apparently allochthonous in Taiwan. The following synonymy is formalized: Epanerchodus orientalis orientalis Attems, 1901 = Epanerchodus orientalis takakuwai Verhoeff, 1913, syn. n. The genus Usbekodesmus Lohmander, 1932 is formally synonymized with Epanerchodus Attems, 1901, syn. n., resulting in the following new formal transfers: Epanerchodus redikorzevi (Lohmander, 1932), Epanerchodus swatensis (Golovatch, 1991), Epanerchodus varius (Geoffroy & Golovatch, 2004), Epanerchodus anachoretus (Golovatch, 1986), Epanerchodus buddhis (Golovatch, 1986), Epanerchodus occultus (Golovatch, 1986), Epanerchodus sacer (Golovatch, 1987), Epanerchodus theocraticus (Golovatch, 1990) and Epanerchodus theosophicus (Golovatch, 1986), all comb. n. ex Usbekodesmus. The distributions of all seven species of Polydesmidae occurring in Taiwan are mapped and discussed.     

The genus Alphitobius Stephens (Coleoptera,Tenebrionidae, Alphitobiini) in Africa and adjacent islands

All species of the genus Alphitobius Stephens, 1829 (Alphitobiini Reitter, 1917, subfamily Tenebrioninae Latreille, 1802) from Africa and adjacent islands are revised. New species: Alphitobius capitaneus sp. n. from Kenya. New synonyms: Cryptops ulomoides Solier, 1851, syn. n. of Alphitobius diaperinus (Panzer, 1796); Alphitobius rufus Ardoin, 1976, syn. n. of Alphitobius hobohmi Koch, 1953); Peltoides (Micropeltoides) crypticoides Pic, 1916, syn. n. of Peltoides (Micropeltoides) opacus (Gerstaecker, 1871), comb. n. Homonym: Alphitobius ulomoides Koch, 1953 = Alphitobius arnoldi nom. n. New combinations from Alphitobius: Ulomoides basilewskyi (Ardoin, 1969), comb. n.; Peltoides (Micropeltoides) opacus (Gerstaecker, 1871), comb. n. Figures of all examined species are added and a species key is compiled.     

Euptychia boulleti (Le Cerf) n. comb. (Lepidoptera: Nymphalidae: Satyrinae), a Rare and Endangered Butterfly from Southeastern Brazil

This paper discusses the systematic position of the rare and endangered satyrine butterfly Caenoptychia boulleti Le Cerf, the only included species in Caenoptychia (type species), based on adult morphology and molecular data. The results showed that Caenoptychia Le Cerf belongs to the Euptychia Hübner clade, and the genus is synonymized with Euptychia, new synonymy. Euptychia boulleti (Le Cerf) is a new combination. The male genitalia of E. boulleti showed at least one important synapomorphy with the other species of Euptychia, which is the presence of a posterior projection of the tegumen above the uncus. Molecular data reinforces the position of Caenoptychia within the genus Euptychia.     

Molecules,morphology and Mimeoma scarabs: evolutionary and taxonomic implications for a palm‐associated scarab group

Cyclocephaline scarabs, the second largest tribe of rhinoceros beetles, are important pollinators of early‐diverging angiosperm families in the tropics. The evolutionary history of cyclocephaline genera is poorly resolved and several genera are thought to be nonmonophyletic. We assess the monophyly of Mimeoma Casey, a group of Neotropical palm‐feeding scarabs, and its relationship to Cyclocephala with a phylogenetic analysis of 2899 bp of DNA sequence data and 18 morphological characters. All five species of Mimeoma were included in analyses along with species of Cyclocephala Dejean, Dyscinetus Harold and Tomarus Erichson as outgroup taxa. Nearly complete 28S, 12S and CO1 data were collected from 26 of 29 specimens, of which 16 samples were pinned, museum specimens. 28S data strongly support a nonmonophyletic Mimeoma; mitochondrial data (CO1 and 12S) suggest that Mimeoma species are nested within an apical clade of other Cyclocephala species; combined molecular and morphological data identify two strongly supported clades of Mimeoma species but do not support their sister relationship. Combined data show that Mimeoma species are nested within Cyclocephala, thus rendering Cyclocephala paraphyletic. Mimeoma is synonymized within Cyclocephala resulting in the following new combinations: Cyclocephala acuta Arrow n.comb ., Cyclocephala englemani (Ratcliffe) n.comb ., Cyclocephala maculata Burmeister n.comb ., Cyclocephala nigra (Endrödi) n.comb . and Cyclocephala signatoides Höhne n.comb . Our results demonstrate that pinned, museum specimens can be used to obtain DNA sequence data (particularly high‐copy gene regions) for evolutionary studies, and provide the first empirical support that host‐plant associations within cyclocephaline scarab clades are conserved at the plant family‐level.     

Phylogenetic relationships within Diplotaxini Kirby (Coleoptera: Melolonthidae: Melolonthinae) with emphasis on Liogenys Guérin‐Méneville

Diplotaxini Kirby is one of the 29 tribes of Melolonthinae with Nearctic, Neotropical, Paleartic, Afrotropical and Oriental distribution. According to the current classification, Diplotaxini is composed of 706 species described in 21 genera. Neotropical Diplotaxini comprise 94 species, of which 78 are members of Liogenys Guérin Méneville, the largest Neotropical genus. Until now, no phylogenetic studies on Diplotaxini have tested whether the tribe is natural or artificial. This study tested the relationships among Diplotaxini genera, created hypotheses for better defining them, and assessed the monophyly of Liogenys. Cladistic analyses using 167 adult morphological characters were performed. The 83 included taxa represent three subfamilies of Melolonthidae, four tribes of Melolonthinae, and most genera of Diplotaxini, with emphasis on Liogenys. The data were analysed using parsimony under equal and implied weights. In both analyses, the traditional concept of Diplotaxini is shown to be a polyphyletic assemblage. Empecta Erichson and Clypeasta Fairmaire are closely related to Melolontha melolontha (Linnaeus) and Pseudoliogenys Moser close to Myloxenoides Martínez (Tanyproctini). Pachrodema Blanchard is identified as the sister group of Liogenys. The monophyly of both Pacuvia Curtis and Homalochilus Blanchard is confirmed and the paraphyly of Diplotaxis Kirby is suggested. The analyses strongly supported the polyphyly of Liogenys. To render this genus monophyletic, we transferred L. ferrugata Mannerheim (related to M. melolontha) to Phyllophaga Harris, and L. micropyga Burmeister to Diplotaxis, forming Diplotaxis micropyga (Burmeister, 1855) comb.n. ; and included Homoliogenys tarsalis (Moser) and Hilarianus anguliceps Blanchard in Liogenys. As H. anguliceps is syn. junior of Liogenys punctaticollis, Hilarianus is synonymized with Liogenys. Hilarianus ovalis and Hilarianus rufinus are here assigned to Manonychus, and Hilarianus uniformis and Hilarianus suboblongus to Blepharotoma, forming: Blepharotoma uniformis comb.n. , Blepharotoma suboblongus comb.n. , Manonychus ovalis comb.n. and Manonychus rufinus comb.n.

Xiphomastix De Santis is synonymized with Anagyrus Howards (syn. n.), both included species ( X. nigriceps De Santis and X. bellator De Santis) being transferred to the latter. Propsyllaephagus Blanchard is synonymized with Psyllaephagus Ashmead (syn.n), Aratiscus laevigatus De Santis is transferred to Zeteticontus Silvestri (comb n.) and a key to the South American species of the genus is provided.     

Phylogeny and classification of the Signiphoridae (Hymenoptera: Chalcidoidea)

Abstract. A data set consisting of twenty-eight anatomical characters scored for twenty-eight terminal taxa representing the world fauna of Signiphoridae was analysed using parsimony and compatibility methods. The Coccophaginae (Aphelinidae) and the Azotinae (Aphelinidae) were used as outgroups to establish polarity of character state changes. Relationships of Signiphoridae to other Chalcidoidea are discussed. Several multistate characters were treated in the parsimony analyses either as unordered or as ordered into transformation series using additive binary coding, which in some cases drastically reduced the number of equally parsimonious solutions. Monophyly of Signiphoridae is supported by seven synapomorphies. Four genera, Chartocerus, Thysanus, Clytina and Signiphora , are recognized within Signiphoridae based on synapomorphies. Rozanoviella syn.n . and Kerrichiella syn.n . are synonymized under Signiphora. Species of Signiphora are further assigned to four species groups, three of which are demonstrably monophyletic. Nine species or subspecies are transferred to Chartocerus from Signiphora ( australicus comb.n. , australiensis comb.n. , australiensis orbiculatus comb.n., beethoveni comb.n. , corvinus comb.n. , funeralis comb.n. , reticulata comb.n. , ruskini comb.n. , thusanoides comb.n.) , one species to Thysanus from Signiphora (melancholicus comb.n.) , and one species to Signiphora from Kerrichiella ( coleoptratus comb.n.) . A key to genera of Signiphoridae and species groups of Signiphora is presented. A diagnosis, relevant nomenclatural history, and a list of included species are given for each genus and species group, and the biology and distribution of each is summarized.     

The American scale insect genus Udinia De Lotto (Coccidae)

Udinia, an Ethiopian coccid genus, is redefined and a key is given to the thirteen species now recognised: bruncki sp. n. , catori (Green) comb. n. [= Lecanium subhirsutum Newstead syn. n. ], farquharsoni (Newstead) [= U.exoleta (De Lotto) syn. n. ], glabra De Lotto, ikoyensis sp. n. , lobayana (Balachowsky & Ferrero) comb. n. , newsteadi sp. n. , nigeriensis sp. n. , pattersoni sp. n. , paupercula De Lotto, pterolobina De Lotto, scitula De Lotto, setigera (Newstead). Five species are described as new and three species are redescribed and for these lectotypes are designated. The morphological characters used are discussed and listed and intraspecific variations shown by two of the species are tabulated. The distribution of all the species is recorded on two maps and the literature dealing with associations between ants and Udinia and related coccid genera is briefly reviewed.     

A revision of the Oriental stonefly genus Phanoperla (Plecoptera: Perlidae)

The genus Phanoperla (=Dyaperla Banks, 1939) (Plecoptera: Perlidae: Perlini) is revised and generic diagnoses are provided for adults and larvae. Diagnostic and constitutive characters of the tribe Neoperlini are discussed, and Chinoperla Zwick, 1980, is shown to be the closest relative of Phanoperla. Many past misidentifications of Phanoperla species have been corrected by the use of characters recently recognized as important, namely the structure of the internal genitalia of male and female specimens and particularly the complex pattern of spines on the male penial sac made visible by eversion of this structure, and details of sculpturing of the egg chorion.
The following species of Phanoperla are recognized: amorpha sp.n.; anomala (Banks, 1939); bakeri (Banks, 1924); ceylonica Kawai, 1975; comuta sp.n.; flaveola (Klapálek, 1921), comb.n. ( =clarissa (Banks, 1913), syn.n.), (=Neoperla hageni Banks, 1920, syn.n.), (= N.consimilis Banks, 1924, syn.n.); guttata sp.n.; himalayana Zwick, 1977 (= siwalika Harper, 1977); limosa (Hagen, 1858); maculata sp.n.; maindroni (Navas, 1926), comb.n.; malayana sp.n.; minutissima (Enderlein, 1909); nana sp.n.; nervosa Banks, 1939; nuwara Kawai, 1975; omega sp.n.; pallipennis (Banks, 1938); parva sp.n.; pumilio (Klapálek, 1921), comb.n.; peniculus Kawai, 1969a; schmidi sp.n.; sertispina Jewett, 1975; srilanka sp.n.; sumatrae sp.n.; testacea (Hagen, 1858); wedda sp.n. P.claggi (Banks, 1938) is a nomen nudum.
All species are (re-)described and figured; all primary types have been examined. A key to species is provided. Most species can be assigned to one of seven species groups which are defined.
Phanoperla is endemic to the Oriental Region. Species groups are generally widespread, but individual species are in most cases known only from restricted areas.     

Molecular insights into the phylogeny of Blapstinina (Coleoptera: Tenebrionidae: Opatrini)

The monophyly of the North and South American endemic subtribe Blapstinina (Tenebrionidae: Opatrini) is tested through phylogenetic analyses using five molecular markers [nuclear ribosomal 28S (28S), cytochrome oxidase subunit II (COII), arginine kinase (ArgK), carbamoyl-phosphate synthetase domain of rudimentary (CAD), wingless (wg)]. Representatives of several opatrinoid subtribes were taken into consideration, including other geographically overlapping endemic genera, namely Ammodonus, Ephalus and Pseudephalus (all previously considered representatives of Ammobiina). A comparative study of morphology was performed to assess resulting phylogenetic hypotheses. Analyses support the monophyly of Blapstinina; however, they also strongly indicate that Ammodonus should be included within the subtribe. Mecysmus is nested within Blapstinus and therefore, a new synonymy, Blapstinus (= Mecysmus syn.n. ), and the following combinations are introduced: Blapstinus advena comb.n. , B. angustus comb.r. , B. laticollis comb.n. , B. parvulus comb.n. , B. tenuis comb.n. Morphological analysis showed a close affiliation between Ephalus and Pseudephalus. Based on these results, Pseudephalus is synonymized with Ephalus [Ephalus (= Pseudephalus syn.n. )], and the following combination is introduced: Ephalus brevicornis comb.n. Recovered topologies also strongly support transferring Ephalus stat.n. into Opatrina, making the distribution of Opatrina amphi-Atlantic.
