First mesozoic representative of the subfamily tenebrioninae (Coleoptera,Tenebrionidae) from the lower cretaceous of Yixian (China,Liaoning)

A new genus and a new species of the tenebrionine tribe Alphitobiini, Alphitopsis initialis gen. et sp. nov. is described from Yixian (Liaoning Province, China). The new genus is the oldest member of the subfamily Tenebrioninae and it is most similar to Metaclisa Jacquelin du Val, 1861, but differs from all the genera of the tribe Alphitobiini in the structure of elytral epipleura and antennae.     

Systematic revision of Aluntiini Emeljanov, 1979 (Hemiptera: Fulgoromorpha: Dictyopharidae: Dictyopharinae): reclassification,phylogenetic analysis,and biogeography

The dictyopharid planthopper tribe Aluntiini s.l. is revised and reclassified into two tribes: Aluntiini s.s. and Arjunini Song & Szwedo trib. nov. The tribe Aluntiini s.s. includes five genera: Aluntia Stål, 1866; D endrophora Melichar, 1903 stat. rev. ; Dictyomorpha Melichar, 1912; Indodictyophara Liang & Song, 2012; and Madagascaritia Song & Liang gen. nov. The new tribe Arjunini comprises two genera – Arjuna Muir, 1934 and Pippax Emeljanov, 2008 – both moved from Aluntiini s.l. Four new species – A luntia longicephalica Song & Szwedo sp. nov. , Madagascaritia angusta Song & Liang sp. nov. , Arjuna maai Song & Wang sp. nov. , and Arjuna muiri Song & Wang sp. nov. – are described. A morphologically based phylogenetic analysis is undertaken for Aluntiini, Arjunini, and the representatives of Dictyopharini, Hastini, Orthopagini, and the fossil Worskaitini within Dictyopharinae, all distributed in the Old World. A matrix of 129 characters of the habitus, coloration, head, thorax, and male and female genitalia of the adults was used for the cladistic analysis. The phylogenetic results show that Aluntiini s.l. as placed in Dictyopharidae is well supported, but it is distinctly paraphyletic and should be separated into two unambiguous tribes. A palaeotropical distribution pattern displayed by Aluntiini is suggested. The origin and diversification of Aluntiini are discussed preliminarily. © 2015 The Linnean Society of London     

A new tribe of the subfamily cretonemonychinae (Coleoptera, Nemonychidae) from the Middle Eocene of the Green River

A new tribe, Eocaenonemonychini trib. nov., and a new genus and new species Eocaenonemonyx kuscheli gen. et sp. nov. are described from the Middle Eocene of the Green River (United States). The new tribe differs from the nominate tribe Cretonemonychini in the open procoxal cavities, very narrow mesocoxae, large mandibles, elongate maxillary palpi, and strongly elongate tarsomere 1.     

TAXONOMICAL STUDIES ON ARGIDAE (HYMENOPTERA) OF CHINA— A NEW GENUS AND FIVE NEW SPECIES OF STERIC-TIPHORINAE*

Abstract A key is given for the known Palaearctic and Oriental genera of the family Argidae including a new genus from China. Ortasiceros gen. nov. with five new species, O. nigriceps sp. nov., O. zhengi sp. nov., O. breoicornis sp. nov., O. curvata sp. nov. and O. elevata sp. nov. are described and figured. A new tribe, Ortasicerini trib. nov., is erected for the new genus and Copidocerus Forsius 1921. The type specimens are deposited in the Insect Collection of Central South Forestry University, Zhuzhou, China.     

A partial revision of Gyptis (Gyptini,Ophiodrominae, Hesionidae,Aciculata, Annelida), with descriptions of a new tribe,a new genus and five new species

Phylogenetic analyses of molecular data (COI, 16SrDNA, 18SrDNA, and 28SrDNA) show that the hesionid genus Gyptis Marion & Bobretzky in Marion, 1874, and the tribe Gyptini Pleijel, 1998, are nonmonophyletic as currently delineated. We introduce the new tribe Amphidurini and the new genus Neogyptis to accommodate these new findings. Amphidurini is sister to Gyptini and Ophiodromini and includes Amphiduros Hartman, 1959, Amphiduropsis, Pleijel, 2001, Neogyptis gen. nov. , and, possibly, Parahesione Pettibone, 1956. Morphologically, Amphidurini can be separated from Gyptini by the distally, rather than subdistally, inserted ventral cirri, and Neogyptis by the combination of this feature, the presence of a median antenna, and a distal ring with papillae on the proboscis. We redescribe and transfer the four species Gyptis crypta Pleijel, 1993, Gyptis mediterranea Pleijel, 1993, Gyptis plurisetis Hilbig, 1992, and Gyptis rosea (Malm, 1874) from Gyptis to Neogyptis gen. nov. , and describe five new species from shallow waters in Belize, Hong Kong, off Vladivostok, and deep‐sea hydrothermal vents in the Lau Basin off Fiji.

A new species of <Emphasis Type="Italic">Paroxyaena</Emphasis> (Hyaenodontidae,Creodonta) from phosphorites of Quercy,Late Eocene,France

An almost complete skull without a lower jaw of Paroxyaena pavlovi sp. nov. (Pterodontinae) is described. A new tribe, Paroxyaenini tribe nov., is established. The round foramen and orbital fissure of Paroxyaenini are completely fused, whereas those of Pterodontini are separate. The deciduous teeth of Paroxyaena are described for the first time.     

Mesozoic leaf beetles of the tribe Mesolpinini trib. nov. (Coleoptera,Chrysomelidae) from the Lower Cretaceous

This publication is based on recent studies of Lower Cretaceous leaf beetles from the Yixian Formation (Liaoning, China), which are represented by five new species of one new genus Mesolpinus gen. nov. (M. antenattus sp. nov. [type species], M. adapertilis sp. nov., M. angusticollis sp. nov., M. basicollis sp. nov., and M. trapezicollis sp. nov.) assigned to a new tribe, Mesolpinini trib. nov. of the subfamily Chrysomelinae. This tribe, which includes only species from the Jehol biota, is the oldest known group of the family in the fossil record. A key to species of the genus Mesolpinus gen. nov. is provided and the position of the new tribe is discussed. A brief overview of the Mesozoic data on the subfamily Chrysomeloidea is given.     

Pselaphotumulus,a new genus of pselaphine endemic to New Zealand (Coleoptera: Staphylinidae: Pselaphinae: Pselaphitae)

ABSTRACT

Pselaphotumulus Owens and Carlton, gen. nov., is described as the sixth genus in the tribe Pselaphini known from New Zealand. Three new species are described: Pselaphotumulus aorerei, sp. nov., Pselaphotumulus dubius, sp. nov. and Pselaphotumulus unus, sp. nov.. Three species, Pselaphus cavelli (Broun 1893), Pselaphus oviceps (Broun 1917) and Pselaphus urquharti (Broun 1917) are transferred to Pselaphotumulus, nov. combs. Lectotypes from type series in the New Zealand Broun Collection (Natural History Museum, London) are designated for these three species. Habitus photographs, distributional maps and line drawings of diagnostic characters are provided for each species. A key to species is provided. Searches of museum collections have not yielded representatives outside of New Zealand, suggesting that this is the first endemic genus in the tribe Pselaphini described from the New Zealand’s main islands, specifically, the South Island. Pselaphotumulus species exhibit restricted distribution patterns that approximately coincide with the Pacific/Indo Australian Plate boundary.     

New click beetles (Coleoptera: Elateridae) from the cretaceous of Russia and Kazakhstan

A new tribe, two new genera, and seven new species of click beetles are described: Pollostelaterini, trib. nov., Pollostelater baissensis, gen. et sp. nov. from the Lower Cretaceous of Transbaikalia (Baisa locality), five new species in the genus Cryptocoelus Dolin et Nel C. sinitshenkovae, sp. nov. (Romanovka locality), C. shcherbakovi, sp. nov., C. baissensis, sp. nov., C. lukashevichae, sp. nov., C. dolini, sp. nov. (all from Baisa locality), and Turonelater giganteus, gen. et sp. nov. from the Turonian of Southern Kazakhstan (Kzyl-Dzhar locality).     

Phylogeny, classification, and biogeography of the cycloteline Therevinae (Insecta: Diptera: Thereavidae)

Twenty-one members of the Laurasian group of Therevinae (Diptera: Therevidae) are compared using 65 adult morphological characters. Cladistic analysis using parsimony on the 17 ingroup and 4 outgroup taxa provides a well-supported hypothesis of relationships among taxa within the Gyclotelini, tribe nov. The Cyclotelini is a monophyletic assemblage of mostly New World genera, including Anolinga , gen. nov. , Breviperna Irwin, Coleiana , gen. nov. , Crebraseta , gen. nov. , Cyclotelus Walker, Mesonana , gen.nov. , and Ozodiceromyia Bigot. In addition, three Old World genera, Ammothereva Lyneborg, Bugulaverpa , gen. nov. , and Procyclotelus Nagatomi & Lyneborg, are included in the tribe. These ten genera are divided into two monophyletic genus-groups, the Brevipema-group and the Cyclotelus-group. Keys are provided for the genera of Cyclotelini. The tribe, the two informal genus-groups, and all genera are diagnosed; five new genera and six new species are proposed. The biogeographical histories of the genera are discussed in terms of their cladistic relationships using methods of cladistic biogeography. Two major vicariant events account for the current distribution of the tribe. The first relates to the Beringian land bridge connecting western North America and eastern Asia. Second, New World cyclotelines were profoundly affected by the Early Eocene breakup of the archipelagic bridge between North and South America, and the distributions support the hypotheses favouring the continental origin of the Greater Antilles.     

A remarkable new opsiine leafhopper genus (Hemiptera: Cicadellidae: Deltocephalinae) from Southern China,with notes on its phylogenetic position

A remarkable new genus of tribe Opsiini (Deltocephalinae), Yinformibus gen. nov. including Yinformibus menglaensis sp. nov. is described from Yunnan of China. The new genus is placed in the tribe Opsiini based on male adults having a pair of aedeagal shafts, each with its own gonopore. Partial 28S rDNA and Histone H3 sequences are provided for the new species, and a phylogenetic analysis based on these markers for Deltocephalinae retrieved from GenBank suggests Opsiini is monophyletic and supports the placement of Yinformibus gen. nov. in Opsiini. The molecular results placed the new genus in a clade comprising Hishimonus Ishihara, Opsius Fieber, and an undescribed genus from Zambia. Additionally, we also analysed the relationships of Yinformibus gen. nov. with other genera based on morphology.

Phylogenetic relationships in the tribe Oxyptilini (Lepidoptera,Pterophoridae, Pterophorinae) based on morphological data of adults

The monophyly of the tribe Oxyptilini and phylogenetic relationships of the genera embraced in this tribe were examined using 171 (75 binary and 96 multistate) characters of adult morphology. The study material included 98 species of 30 genera, representing all previously recognized genera of Oxyptilini, together with the genera Sphenarches, Antarches, Diacrotricha, and Cosmoclostis, four species of Oidaematophorini, three species of Platyptiliini, as well as three and two other species belonging to Pterophorini and Exelastini respectively. Two Agdistis species were used as outgroups. The cladistic analysis resulted in six equally parsimonious trees. A majority of the recovered synapomorphic characters have previously been used in the taxonomy of the subfamily. However, 25 novel characters were found. The monophyly of Oxyptilini was supported, although only with homoplastic characters and low amounts of tree confidence; the genera Capperia, Procapperia, Paracapperia, Oxyptilus, Megalorhipida, and Trichoptilus were found to be nonmonophyletic; Sphenarches and Antarches were recovered as members of Oxyptilini; the two genera Cosmoclostis and Diacrotricha were placed out of Oxyptilini, inside the tribe Pterophorini; and close affinity of the genus Dejongia to Stangeia, Stenodacma, Megalorhipida, Trichoptilus, and Buckleria species was revealed. Four new combinations, Cosmoclostis lanceata (Arenberger) comb. nov. , Nippoptilia regulus (Meyrick) comb. nov. , Capperia tadzhica (Zagulajev) comb. nov. , and Buckleria negotiosus (Meyrick) comb. nov. are proposed; Capperia insomnis Townsend was considered as a senior synonym of Procapperia hackeri Arenberger syn. nov. , Buckleria negotiosus (Meyrick) as a senior synonym of Buckleria vanderwolfi Gielis syn. nov. , and Oxyptilus variegatus Meyrick syn. nov. as a junior synonym of Oxyptilus secutor Meyrick. © 2011 The Linnean Society of London, Zoological Journal of the Linnean Society, 2011, 163 , 484–547.     

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.     

Neotapirissus gen. nov. of the tribe Issini (Hemiptera: Fulgoromorpha: Issidae) from Hainan Island

Neotapirissus gen. nov. , in the tribe Issini (Hemiptera: Fulgoromorpha: Issidae), is described from China, and type species Neotapirissus reticularis sp. nov. (China: Hainan) is described and illustrated. The female internal reproductive organs of the new species are also described and illustrated. The new genus is compared to the superficially similar genus Tapirissus Gnezdilov. The morphological diversity of the issids distributed in Hainan Island is discussed briefly.     

DEUCALION GEN. NOV. AND ANISOSCHIZUS GEN. NOV. (CERAMIACEAE,CERAMIALES), TWO NEW PROPAGULE-FORMING RED ALGAE FROM SOUTHERN AUSTRALIA1

Two new propagule-farming red algae from southern Australia, Deucalion levringii (Lindauer) gen. et comb. nov. and Anisoschizus propaguli gen. et sp. nov., are described and defined largely on their development in laboratory culture. Deucalion is included in the tribe Compsothamnieae on the basis of its subapical procarp and alternate distichous branching. It differs from the other genera included in that tribe in that it produces 3-celled propagules, polysporangia, a subapical cell of the fertile axis which bears 3 pericentral cells, and an apparently post-fertilization involucre which develops from the hypogenous and sub-hypogenous cells of the fertile axis. Its gametophyte morphology has been elucidated in culture, as only sporophytes are known from the field. Gametophytes do not appear to produce propagules. Anisoschizus is provisionally included in the tribe Spermothamnieae on the basis of its subdichotomous branching, possession of a prostrate system and the production of polysporangia. It differs from the other genera of the tribe in the production of 2-celled propagules. Observations on the germination of the “monosporangia” of Mazoyerella arachnoidea and Monosporus spp. indicate that they are analagous to the propagules of Deucalion and Anisoschizus. The nature of these propagules and their role in recycling the parent plant are discussed and contrasted with true monosporangia. It is recommended that Monosporus be maintained as a form genus containing representatives from more than one tribe, as exemplified by plants from Lord Howe I. provisionally identified as M. indicus Boergesen which have both prostrate and erect, as opposed to only erect, axes.     

New gall midges of the tribe Leptosynini (Diptera,Cecidomyiidae) from the Late Eocene ambers and the classification of the supertribe Heteropezidi

Three new genera and 27 new species of gall midges are described from the Late Eocene ambers: Henria baltica sp. nov., Frirenia manca sp. nov., F. musicata sp. nov., Leptosyna samlandica sp. nov., L. fastosa sp. nov. from Baltic amber and H. xystica sp. nov., H. liquida sp. nov., Stellasegna vlaskini gen. et sp. nov., S. vaporea sp. nov., S. nexa sp. nov., Rasnitsia verticosa gen. et sp. nov., F. rohdendorfi sp. nov., F. schevchenkoi sp. nov., F. melica sp. nov., F. lukashevichae sp. nov., F. leporidis sp. nov., F. marmarygma sp. nov., F. vesana sp. nov., Vincinescia alisae gen. et sp. nov., L. margarita sp. nov., L. munifera sp. nov., L. sukachevae sp. nov., L. assa sp. nov., L. larga sp. nov., L. vegeta sp. nov., L. vaticina sp. nov., and L. shcherbakovi sp. nov. from Rovno amber. Strobliella capitata Fedotova is redescribed as Henria capitata (Fedotova, 2004) (comb. nov.). Diagnoses of Henria (= Electroxylomyia Nel et Prokop, syn. nov.), Frirenia, and Leptosyna are revised. As a result, Henria comprises 3 extant and 5 extinct (Late Eocene) species, including H. eocenica (Nel et Prokop), comb. nov. (= Electroxylomyia eocenica), Frirenia comprises 1 extant and 10 Late Eocene species, and Leptosyna comprises 3 extant and 11 Late Eocene species. The tribe Heteropezini is elevated to the supertribal rank (Heteropezidi) and included in the subfamily Lasiopterinae. Leptosynini is treated as a separate tribe, and Lasiopterinae is considered as part of Cecidomyiidae s. str. (i.e., excluding Lestremiidae). Keys to the tribes and genera of Heteropezidi and to species of Henria, Stellasegna, Frirenia, and Leptosyna are provided. The gall midge faunas of the Rovno and Baltic ambers are compared. Phylogenetic relationships within the supertribe are hypothesized.     

New species of Lonchaeidae (Diptera: Schizophora) from Japan and a re‐evaluation of genus Setisquamalonchaea Morge

Three new species of Lonchaeidae are described from material reared from fig syconia in Japan: Silba inubiwa sp. nov., S. ishigaki sp. nov. and S. japonica sp. nov. Based on the taxonomy of these and similar species the boundaries of the genus Silba are re‐evaluated, and, as a result, it is considered that Setisquamalonchaea Morge is synonymous with Silba Macquart. A revised key and generic notes on the tribe Lonchaeini are provided.
