Molecular phylogeny of the beetle tribe Oxypodini (Coleoptera: Staphylinidae: Aleocharinae)

This is the first study to comprehensively address the phylogeny of the tribe Oxypodini Thomson and its phylogenetic relationships to other tribes within the staphylinid subfamily Aleocharinae. Using the hitherto largest molecular dataset of Aleocharinae comprising of 4599 bp for representatives of 22 tribes, the Oxypodini are recovered as non‐monophyletic. Members of the tribe belong to three distantly related lineages within the Aleocharinae: (i) the Amarochara group as sister clade to the tribe Aleocharini, (ii) the subtribe Tachyusina within a clade that also includes the tribes Athetini and Hygronomini, (iii) all other Oxypodini in a clade that also includes the tribes Placusini, Hoplandriini and Liparocephalini. Based on the inferred phylogeny, five subtribes of the Oxypodini are recognized: Dinardina Mulsant & Rey, Meoticina Seevers, Microglottina Fenyes, Oxypodina Thomson and Phloeoporina Thomson. The following changes in the classification of the Aleocharinae are proposed: (i) Amarochara Thomson is removed from the Oxypodini and placed in the tribe Aleocharini; (ii) the subtribe Taxicerina Lohse of the Athetini is reinstated as tribe Taxicerini to include Discerota Mulsant & Rey, Halobrecta Thomson (both removed from the Oxypodini) and Taxicera Mulsant & Rey; (iii) the subtribe Tachyusina Thomson is excluded from the Oxypodini and provisionally treated as tribe Tachyusini; (iv) the oxypodine subtribe name Blepharhymenina Klimaszewski & Peck is placed in synonymy with the subtribe name Dinardina Mulsant & Rey.     

First record of the tribe Trigonoderini (Hymenoptera: Pteromalidae) from South Korea with descriptions of two new species

The tribe Trigonoderini (Hymenoptera: Pteromalidae) contains six genera (Gastracanthus Westwood, Janssoniella Kerrich, Miscogasteriella Girault, Platygerrhus Thomson, Plutothrix Förster and Trigonoderus Westwood). This tribe is recorded from South Korea for the first time. Two new species, Janssoniella albiclava Tselikh & Lee sp. nov. from South Korea and J. magna Tselikh & Lee sp. nov. from South Korea and the South Far East of Russia, are described. Eight species (Gastracanthus acutus (Kamijo), G. nigrescens Kamijo, Janssoniella intermedia Hedqvist, Miscogasteriella sulcate (Kamijo), Plutothrix scrobicula Kamijo, P. trifasciata (Thomson), Trigonoderus fraxini Yang and T. nigrocephalus Kamijo) are recorded from South Korea for the first time. The keys for identification of the Eastern–Palearctic species of Janssoniella and Gastracanthus are given and photos of diagnostic characters of the new species are provided.     

Revision of the tribe Colpopterini Gnezdilov, 2003 (Homoptera, Fulgoroidea: Nogodinidae)

The tribe Colpopterini Gnezdilov, 2003 is revised, upgraded to the subfamily Colpopterinae, stat. n., and transferred from the family Issidae Spinola to Nogodinidae Melichar. The tribe Colpopterini is recorded from the Afrotropical Region for the first time—Bumerangum deckerti gen. et sp. n. is described from Southern Africa. The tribe Colpopterini s. str. comprises 6 genera: Bumerangum gen. n., Caudibeccus Gnezdilov et O’Brien, 2008, Colpoptera Burmeister, 1835, Jamaha Gnezdilov et O’Brien, 2008, Neocolpoptera Dozier, 1931, and Ugoa Fennah, 1945. The genera Cheiloceps Uhler, 1895, Tempsa Stål, 1866, Eupilis Walker, 1857, and Gabaloeca Walker, 1870 are transferred to the tribe Issini Spinola of the family Issidae. Issus longulus Lethierry, 1890 is transferred to the genus Colpoptera Burmeister. A key to the genera and a list of the species of the tribe Colpopterini are given. Morphological data confirming independent evolution of similar ovipositor types in the families Issidae and Nogodinidae are provided. The term “styletization” is suggested for describing the transformation of the ovipositor from a rounded to an elongate type.     

Bobgunnia, a new African genus of tribe Swartzieae (Fabaceae, Faboideae)

A new genus, Bobgunnia, is established in tribe Swartzieae for the African species of Swartzia. Two new combinations are made: B. fistuloides and B. madagascariensis. The new genus has seeds, unlike the remainder of tribe Swartzieae but like the other tribes of Faboideae. The systematic position of Swartzieae is reevaluated.     

Trichelodes (=Hexanodes), type of Trichelodini new tribe,and its affinities with the Trinodini (Coleoptera: Dermestidae)

Abstract

Hexanodes Blair, 1941 from New Zealand is synonymous with the Australian genus Trichelodes Carter, 1935, here transferred from the Dascillidae (sensu Carter) to the monotypic new dermestid tribe Trichelodini. Couplets for Trichelodini and the closely related Trinodini are given for integration into Crowson's key to the subfamilies (= tribes?) of Dermestidae. The genera of Trinodini and the two known species of Trichelodes are keyed. Trichelodes delicatula (Australia) and T. vulgata (New Zealand) are redescribed; a lectotype is designated for vulgata, and its synonymy is updated.     

Synopsis of the tribe Bocageeae (Annonaceae), with revisions of Cardiopetalum,Froesiodendron, Trigynaea,Bocagea, and Hornschuchia

The tribal name Bocageeae Endlicher is reestablished and the tribe is circumscribed on the basis of solitary internodal ebracteate pedicels that are articulated at the base, and pollen shed in polyads of eight or more grains. Septate anther locules, large pollen size, and seed appendages are prevalent in the tribe. Intectate pollen with free-standing columellae, rare in Annonaceae, occurs not only in the genusTrigynaea but also in some species ofBocagea andHornschuchia. As defined here, the Bocageeae include seven neotropical genera:Cymbopetalum, Porcelia, Bocagea, Cardiopetalum, Froesiodendron, Hornschuchia, andTrigynaea. The latter five genera are revised and the treatments include ten new species:Cardiopetalum plicatum, Froesiodendron urceocalyx, Hornschuchia lianarum, H. santosii, H. leptandra, Trigynaea cinnamomea, T. lanceipetala, T. triplinervis, T. lagaropoda, andT. axilliflora, all from tropical South America. A new combination,Froesiodendron longicuspe, changes the rank of that taxon from subspecies to species.Cardiopetalum surinamense is removed fromFroesiodendron and reassigned toCardiopetalum on the basis of its connate petals, dehiscent monocarps, and seeds with bilobed arils. A cladogram provides an explicit hypothesis of intergeneric relationships in the tribe. The new combinationOnychopetalum periquino, based onTrigynaea periquino, is made.     

New and little known planthoppers of the subfamily Ommatidiotinae (Homoptera,Fulgoroidea, Caliscelidae) from Madagascar and South Asia

Cano merinus gen. et sp. n., belonging to the tribe Augilini Baker, is described from Madagascar. Tubilustrium typicum Distant, 1916 is transferred from the tribe Ommatidiotini Fieber to the tribe Augilini. Lasonia kirkaldyi Melichar, 1903 is transferred from the family Issidae to the family Caliscelidae, tribe Adenissini Dlabola. A key to the tribes of the subfamily Ommatidiotinae is provided.     

The tribe Bryocorini (Insecta: Heteroptera: Miridae: Bryocorinae): phylogeny,description of a new genus,and adaptive radiation on ferns

A cladistic analysis of the tribe Bryocorini based on 68 morphological characters is conducted. Bryocorini are supported as a monophyletic group with Eccritotarsini as their sister taxon. Based on the phylogenetic analysis, we redefine the tribe Bryocorini to contain the following seven genera: Bryocorella Carvalho, 1956, Bryocoris Fallén, 1829, Bryophilocapsus Yasunaga, 2000, Cobalorrhynchus Reuter, 1906 gen. dist., D iplazicoris gen. nov. , Hekista Kirkaldy, 1902, and Monalocoris Dahlbom, 1851. The genus Bryocorella is transferred to Bryocorini from the tribe Eccritotarsini. The subgenus Cobalorrhynchus is treated as a separate genus. Diplazicoris is described as monotypic to accommodate D iplazicoris lombokianus sp. nov. An updated diagnosis of the tribe, a key to genera, and a diagnosis of each recognized genus are presented. Selected photomicrographs, scanning micrographs, and illustrations of the pretarsus, metepisternal scent efferent system, metafemoral trichobothria, and morphology of head, pronotum, and male and female genitalia are provided. Mapping of the host data on the revealed tree shows that Bryocorini represent one of the very few currently known examples of the adaptive radiation of a fairly large insect group on ferns. © 2015 The Linnean Society of London     

Discovery of a new fossil soldier beetle in Eocene Baltic amber,with the establishment of the new tribe Cacomorphocerini

Eocene forest ecosystems can be considered as rich biodiversity hotspots regarding soldier beetles (family Cantharidae). Paleogene European ambers, for instance, comprised many genera that are still extant in Europe, but also extinct forms and lineages such as the tribe established herein, or the tribe Mimoplatycini Kazantsev, 2013 that mimics the lycids. In this note, the authors describe Cacomorphocerus wiszniewskii sp. nov., and the new tribe Cacomorphocerini tri. nov. is proposed for Cacomorphocerus Schaufuss, 1892 and Sucinocantharis Ku?ka and Kania, 2010. The new tribe is characterized by antennae with 12 or 16 articles, with saucer-shaped or dilated central antennomeres and is distributed in Eocene Baltic and Rovno amber. Furthermore, Cacomorphocerus is transferred from the subfamily Dysmorphocerinae Brancucci, 1980 to Cantharinae Imhoff, 1856.     

Hyaloscyphaceae in Japan (1): Non-glassy-haired members of the tribe hyaloscypheae

Discomycetes of the family Hyaloscyphaceae were collected from across Japan and identified. In this report, non-glassy-haired members of the tribe Hyaloscypheae, subfamily Hyaloscyphoideae are described and illustrated. The five species involved include one new species (Phialina lacrimiformis) and four species less well known or newly reported in Japan (Dematioscypha dematiicola, Hamatocanthoscypha laricionis var.Iaricionis, Micropodia chrysostigma, M. grisella). cultural studies were carried out, and teleomorph-anamorph relationships are discussed forD. dematiicola, H. laricionis val.laricionis and their anamorphs. A key to the genera of the tribe Hyaloscypheae in Japan is provided.     

Phylogeny and classification of diving beetles in the tribe Cybistrini (Coleoptera, Dytiscidae, Dytiscinae)

Phylogenetic relationships among members of the diving beetle tribe Cybistrini (Coleoptera: Dytiscidae) were inferred from analysis of 47 adult and larval morphological characters and sequences from portions of the genes cytochrome oxidase I (COI) and II (COII), histone III (H3) and wingless. Thirty‐three species of Cybistrini were included, representing all genus‐groups except Regimbartina Chatanay and Megadytes (Bifurcitus) Brinck, and most historically recognized species groups and subgenera used in the tribe. Outgroups include six species from other tribes within Dytiscinae and Lancetinae. Analyses included parsimony analysis of the combined data, likelihood analysis of combined molecular data and partitioned Bayesian analysis of the combined data. Results indicate that Cybistrini is well supported as a monophyletic group. Within the tribe, all currently recognized genus groups were found to be monophyletic with the exception of Onychohydrus Schaum, which is paraphyletic with respect to Austrodytes Watts in the parsimony analysis, but monophyletic in the likelihood and Bayesian analyses, and Cybister sensu stricto, which is paraphyletic with respect to C. (Melanectes) Brinck and C. (Scaphinectes) Ádám in the parsimony analysis or only the latter in the likelihood and Bayesian analyses. Results also suggest that some, but not all, historically recognized species groups or subgenera in the large genus Cybister Curtis are monophyletic, and this is discussed and compared. To improve the classification, the name Sternhydrus Brinck is elevated from subgenus to genus rank ( new status ). Four subgenera in the genus Cybister are recognized: C. (Melanectes) Brinck, C. (Megadytoides) Brinck ( resurrected ), C. (Neocybister) Miller, Bergsten and Whiting ( new subgenus ) and C. (Cybister) Curtis. The following new synonyms are established: Trochalus Dejean ( new synonym ), and ScaphinectesÁdám = Cybister (Cybister) ( new synonym ). The Neotropical species Cybister parvus Trémouilles (not examined) apparently does not fit any historical or currently recognized genus‐group diagnosis in Cybistrini, so it is retained in Cybister but incertae sedis with respect to subgenus. In addition to classification, the evolution of the unique character combinations present in cybistrines are discussed. A key to the adults of genera and subgenera is presented.     

Independent origins of coastal colonization in the tribe Athetini (Coleoptera,Staphylinidae)

Less than 1% of Staphylinidae are known to be confined to coastal habitats. To explore the origins of coastal colonization within the tribe Athetini Casey, we present a revised molecular phylogeny. The dataset comprised partial mitochondrial COI, COII, 16S rDNA, NADH1, partial nuclear 18S rDNA and 28S rDNA. We chose a total of 95 species in 51 genera, including 14 coastal species in eight genera and 21 outgroup species from other aleocharine tribes. The concatenated dataset was analysed simultaneously by both parsimony‐ and model‐based (Bayesian and maximum likelihood) methods. The tribe Athetini was not supported as a monophyletic group, but together with the tribes Tachyusini, Ecitocharini and Hygronomini did form a monophylum. The ecological association of species with a coastal habitat was mapped onto a phylogeny to assess the evolution of habitat specialization in the Athetini lineage. The results reveal that five independent origins of coastal colonization have occurred throughout the tribe Athetini: (a) Osakatheta + Adota minuta + coastal Atheta (Badura) (clade A); (b) Adota (clade B); (c) Pontomalota + Tarphiota + Thinusa (clade C); (d) Iotarphia (clade D); and (e) Psammostiba (clade E). The low species number of the coastal Athetini compared with the entire Athetini lineage indicates that coastal habitats are harsh environments and so only a few species were able to colonize this habitat. The following changes in classification are proposed: (a) Ad. minuta Lee and Ahn is removed from the genus Adota and tentatively included in Atheta (Badura); (b) The genus Saphocallus Sharp is transferred from Athetini to Geostibini.     

A new tribe of fossil digger wasps (Insecta: Hymenoptera,Crabronidae) from the Rovno amber,Eocene of Ukraine

A new tribe of digger wasps, Protomicroidini trib. nov. (Hymenoptera, Crabronidae), including a single known species Protomicroides sororius gen. et sp. nov. is described from the Upper Eocene Rovno amber, Ukraine. The new tribe combines features characteristic of several tribes of the Crabroninae and is a sister group of the extant tribe Oxybelini. The most distinctive characters of the new tribe include nonelongate propodeum with strongly developed lateral keel and enclosed dorsal area; semioval postscutellum with a lamellate border; absence of pygidial plate, psammophores, and digging tarsal rakes; and considerably reduced forewing venation.     

Cladispa Baly: revision,biology and reassignment of the genus to the tribe Spilophorini (Coleoptera: Chrysomelidae: Cassidinae)

The genus, Cladispa Baly 1858, is transferred from the tribe Imatidiini (= Cephaloleiini Chapuis, 1875) to Spilophorini Chapuis, 1875 based on the review of type material, newly collected specimens and molecular phylogenetic analysis. The type species, C. quadrimaculata Baly, 1858, is redescribed, and two new species, C. amboroensis sp.n. from Bolivia (Santa Cruz Department) and C. ecuadorica sp.n. from Ecuador (Pastaza Province), are described and figured. The morphology of C. amboroensis sp.n. immature stages is broadly consistent with other Spilophorini. Field observations document that both C. quadrimaculata and C. amboroensis sp.n. are trophic specialists on Orchideaceae. Keys to Cladispa species and Spilophorini genera are provided. Trophic associations of other Cassidinae and Orchideaceae are discussed. This published work has been registered in ZooBank, http://zoobank.org/urn:lsid:zoobank.org:pub:42A1ECF3‐2030‐4938‐8F3D‐FE7EC36F303A     

Description,circumscription and phylogenetics of the new tribe Zaeucoilini (Hymenoptera: Figitidae: Eucoilinae), including a description of a new genus

Abstract Neotropical eucoiline genera that have been included in and allied with the Zaeucoila genus group are redescribed. Following character analysis and phylogenetic reconstruction (25 taxa, 96 morphological characters, 1452 ribosomal and mitochondrial characters), this informal genus group was found to be monophyletic, and hence raised to formal recognition as a tribe of eucoilines, namely Zaeucoilini new tribe . Through phylogenetic reconstruction, Aegeseucoela Buffington was determined to be polyphyletic; the type species of Aegeseucoela, A. grenadensis (Ashmead), is transferred to Agrostocynips comb.n. ; the orphaned species, A. flavotincta (Kieffer), is transferred to Marthiella Buffington gen.n. , comb.n. Based on the examination of the holotype of Diranchis flavipes Ashmead, 1900 , this species is transferred to Rhabdeucoela comb.n. , where it is both a junior, subjective synonym of flavipes ( Ashmead, 1894 ) syn.n. and a junior, secondary homonym. Zaeucoilini contains the following genera: Agrostocynips Diaz, Dettmeria Borgmeier, Dicerataspis Ashmead, Lopheucoila Weld, Marthiella Buffington, Moneucoela Kieffer, Moritiella Buffington, Penteucoila Weld, Preseucoela Buffington, Rhabdeucoela Kieffer, Tropideucoila Ashmead and Zaeucoila Ashmead. Characters and character states applicable specifically to Zaeucoilini are defined and illustrated. Characters supporting the monophyly of each genus are discussed. The plesiomorphic host for members of the Zaeucoilini are postulated as agromyzid leaf‐mining Diptera, with one shift within the clade containing Dettmeria, Dicerataspis and Lopheucoila to fruit‐infesting Diptera. New host records are reported for species of Preseucoela, Rhabdeucoela and Zaeucoila. All known hosts for the species of each genus are reported, as are known distributions and locations of type specimens.     

Discovery of the tribe Odontalgini (Coleoptera: Staphylinidae; Pselaphinae) in Japan

A new species of the pselaphine genus Odontalgus is described from Honshu, Japan, under the name of Odontalgus masaoi. Odontalgus coreanus Löbl known from North Korea is recorded for the first time from Kyushu, Japan. These are the first formal records of the tribe Odontalgini from Japan.     

Phylogeny,classification and evolution of the water scavenger beetle tribe Hydrobiusini inferred from morphology and molecules (Coleoptera: Hydrophilidae: Hydrophilinae)

The water scavenger beetle tribe Hydrobiusini contains 47 species in eight genera distributed worldwide. Most species of the tribe are aquatic, although several species are known to occur in waterfalls or tree mosses. Some members of the tribe are known to communicate via underwater stridulation. While recent morphological and molecular‐based phylogenies have affirmed the monophyly of the tribe as currently circumscribed, doubts remain about the monophyly of included genera. Here we use morphological and molecular data to infer a species‐level phylogeny of the Hydrobiusini. The monophyly of the tribe is decisively supported, as is the monophyly of most genera. The genus Hydrobius was found to be polyphyletic, and as a result the genus Limnohydrobius stat. rev. is removed from synonymy with Hydrobius, yielding three new combinations: L. melaenus comb.n. , L. orientalis comb.n. , and L. tumbius comb.n. Recent changes to the species‐level taxonomy of Hydrobius are reviewed. The morphology of the stridulatory apparatus has undergone a single remarkable transformation within the lineage, from a simple, unmodified pars stridens to one that is highly organized and complex. We present an updated key to genera, revised generic diagnoses and a list of the known distributions for all species within the tribe.
