Olemehlia krali,a new genus and species of Ripidiinae from Baltic amber (Coleoptera: Ripiphoridae)

A new genus and species, Olemehlia krali n. g. & n. sp. (Coleoptera: Ripiphoridae: Ripidiinae), is described from Baltic amber. The newly described genus is compared with all known fossil and extant closely related genera of the subfamily Ripidiinae. It is characterised by the following combination of characters: antennae consisting of 10 antennomeres, with scape, pedicel, and antennomere 3 simple and antennomeres 4–10 uniflabellate, mouthparts reduced to a small single unpaired tubercle, postocular ommatidia absent, pronotum trapezoid without grooves or impressions, elytra without white apical spots, tarsal formula 5–5–4, hind tarsomere I shorter than three remaining combined. Diversity of Ripiphoridae in Baltic amber is discussed; key to Ripidiinae genera from Baltic amber is provided.     

A new genus and species of the rove beetle tribe Mesoporini from Baltic amber (Coleoptera: Staphylinidae: Aleocharinae)

A new extinct rove beetle, Palaeomesoporus electiricus gen. et sp.n., is described from a single specimen of Eocene Baltic amber. This fossil beetle is placed in the tribe Mesoporini, a ‘basal’ group of the mega-diverse subfamily Aleocharinae. Palaeomesoporus is easily discriminated from other mesoporine genera due to its less-developed antennal club, longer and slender elytron lacking a sinuate posterior margin, and prominently shorter mesotarsus. This finding sheds light on the paleodiversity and evolutionary history of the tribe and ‘basal’ Aleocharinae.     

New gall midges of the subfamily Lestremiinae (Diptera, Cecidomyiidae) from the Rovno amber

Two new genera and eight new species of the gall midges subfamily Lestremiinae, viz. Berestella insuperabilis gen. et sp. nov., Monardia impellucida sp. nov., Xylopriona aristata sp. nov. (Micromyini), Aprionus improvisus sp. nov., A.? vlaskini sp. nov. (Aprionini), Vicemyia immediata gen. et sp. nov. (Peromyiini), Cordylomyia cauta sp. nov. (Campylomyzini) and Bryomyia necessaria sp. nov. (Bryomyiini) from the Late Eocene Rovno amber are described. New combinations, i.e., Cordylomyia declinata (Fedotova, 2004), comb. nov. and Cordylomyia magnifica (Nel et Prokop, 2006), comb. nov. (both are transferred from Neurolyga) are proposed. No species in common with the fauna from the Baltic amber are recorded.     

A new species of Diochus from Baltic amber (Coleoptera, Staphylinidae, Diochini)

The first fossil of the staphylinine tribe Diochini Casey is described and figured from an inclusion in mid-Eocene (Lutetian) Baltic amber. Diochus electrussp. n. is distinguished from its congeners and the diversity of rove beetles (Staphylinidae s.l.) is summarized briefly.     

Redescription of Eatonisca tertiaria Meunier 1905 from Baltic amber (Diptera: Psychodidae: Trichomyiinae)

Eatonisca tertiaria Meunier 1905, is redescribed from the Eocene Baltic amber, with details of the eyes, antennae and male genitalia structure provided. This fossil is placed within Trichomyiinae, and shares several plesiomorphies with Psychodinae, Phlebotominae, and Sycoracinae.     

Turcichondrostoma,a new genus for the Leuciscidae (Teleostei: Cypriniformes) from Southwestern Anatolia

Turcichondrostoma, a new genus, from the Southwestern Anatolia is distinguished by having fewer gill rakers on first gill arch and morphologies of premaxilla and dentary bones. In addition, as a result of the phylogenetic analyses based on combine data set (mtDNA COI + Cytb) sequences (1706 bp.), Turcichondrostoma genus was recovered with high posterior probability value (BI PP:1.0) and strong-supported bootstrap value (ML BP: 100%) among the former Chondrostoma groups. Also, high K2P mean genetic distance values (more than 7.84%) differentiated genus Turcichondrostoma from the other genera of former Chondrostoma group. The results of both morphological-osteological and molecular analyses are congruent with each other. The results of this study revealed that the genus Turcichondrostoma is easily distinguished from the genera in Chondrostoma group.     

New species of bark beetles from the Rovno amber (Insecta: Coleoptera: Scolytidae)

Two new species of bark beetles are described from the Late Eocene Rovno amber. Xylechinus mozolevskae sp. nov. (Hylesininae: Tomicini) is the first fossil representative of this genus, differing from recent species in having large triangular scales along the suture. Taphramites rovnoensis sp. nov. (Scolytinae: Dryocoetini) differs from the closest species, T. gnathotrichus from Baltic amber, in the presence of short thin hairs on the elytra.     

A new genus and species in the tribe Empoascini (Hemiptera,Cicadellidae, Typhlocybinae) from China

Taxonomic notes on the genus Syndiamesa Kieffer (Diptera: Chironomidae) from Japan, with description of a new species

The Japanese species of the genus Syndiamesa are revised. A new species, Syndiamesa longipilosa sp. nov., from Honshu, Japan is described from male and female material. The male of Syndiamesa mira (Makarchenko) from Japan is redescribed and figured. Syndiamesa chuzemagna Sasa is synonymized with Syndiamesa yosiii Tokunaga. Syndiamesa bicolor Tokunaga is transferred to the genus Sympotthastia. A key to males of Japanese Syndiamesa is provided.     

A new species of the bee genus Ctenoplectrella in middle Eocene Baltic amber (Hymenoptera, Megachilidae)

A new species of the extinct bee genus Ctenoplectrella Cockerell (Megachilinae: Ctenoplectrellini) is described and figured from two females preserved in middle Eocene (Lutetian) Baltic amber. Ctenoplectrella phaetonsp. n. is distinguished from its congeners on the basis of its body proportions, integumental sculpturing, wing venation, and pubescence, and is one of the more distinctive members of the genus. A revised key to the species of Ctenoplectrella is provided.     

Abraracourcix curvivenatus n. gen. n. sp. from the Lowermost Eocene Oise amber (Hemiptera: Fulgoromorpha: Ricaniidae)

An extinct genus Abraracourcix n. gen. with A. curvivenatus n. sp. is described based on the specimen from the Lowermost Eocene Oise amber. The venation characters and possible hostplant relationships, as well as taxonomic position and biogeographical pattern of recent Pochazoides generic group are discussed.     

Phylogeny of Grumichellini Morse, 1981 (Trichoptera: Leptoceridae) with the description of a new genus from southeastern Peru

Osflintia manu, new genus, new species, of long-horned caddisfly (Leptoceridae: Triplectidinae: Grumichellini) is described and illustrated from southeastern Peru. The phylogeny of Grumichellini Morse (Leptoceridae: Triplectidinae) is revisited and hypotheses of homology of some morphological characters are reconsidered. The monophyly of the tribe is corroborated and the phylogenetic relationships of its included genera are inferred to be (Triplexa (Gracilipsodes ((Grumichella, Amazonatolica) (Atanatolica, Osflintia, n. gen.)))) from adult and larval characters. Diagnostic characters of the new genus include the following: reduced tibial spur formula (2, 2, 2), loss of forewing crossvein sc-r1, hind wing discoidal cell closed, hind wing fork IV present, pair of long setae on tergum IX of the male genitalia, and pair of processes on the apex of segment X.     

Revision of the genus Epimesoplecia Zhang, 2007 (Diptera,Nematocera, Protopleciidae) with five new species

The genus Epimesoplecia Zhang, 2007 of Protopleciidae is revised based on five new species, Epimesopleciaplethorasp. n., Epimesopleciaprosoneurasp. n., Epimesopleciastanasp. n., Epimesopleciamacrostrenasp. n., and Epimesopleciaambloneurasp. n., described and illustrated from the Jiulongshan Formation of China. These new species, with clearly preserved characters of (1) compound eyes connected in males; (2) antennae, filiform or moniliform, with 16 segments; (3) r-m reaching the middle of the wing; (4) R₄₊₅ ending very close to wing apex; (5) ratio of bRs/dRs ranging from 1.6 to 10.5; (6) M₂ more than 3 times as long as dM₁₊₂; (7) legs thin and long, femur slender, almost equal to tibia; (8) tibial spurs minute; and (9) male genitalia (previously unknown), enable us to emend the diagnosis of Epimesoplecia Zhang, 2007. In addition, all described species of Epimesoplecia are characterized, their features summarized, and a key to Epimesoplecia species is given.

A new genus and species of triggerfish from the Middle Eocene of the Northern Caucasus,the earliest member of the Balistidae (Tetraodontiformes)

Until now, the earliest known members of the triggerfish family Balistidae have been two genera from the Oligocene. Herein is described the new balistid Gornylistes prodigiosus gen. et sp. nov. from the uppermost Middle Eocene (Kuma Horizon) of the Northern Caucasus (Gorny Luch locality); it is as thoroughly modern in its bauplan as the taxa of balistids from the Oligocene and more recent periods, and far more advanced morphologically than the several stem taxa of the balistoid + ostracioid clade known from earlier in the Middle and Lower Eocene and from the Upper Paleocene.

中国新记录巴克斯霉属Backusella的两个分类单元(英文)

最近在中国十个省市发现了一个新记录属——巴克斯霉属Backusella,包括一个种的两个变种,即卷曲巴克斯霉原变种B.circina var.circina和卷曲巴克斯霉改级光孢变种B. circina var. lamprospora stat. nov. ≡ B. lamprospora。文章对这两个变种提供了形态描述和线条图,还提供了属内区分所有可以承认的分类群的检索表。把这两个分类群从种级降为变种级的理由亦有所讨论。ITS rDNA序列分析表明,卷曲巴克斯霉是一个多系类群,与放射毛霉属Actinomucor、毛霉属Mucor和根毛霉属Rhizomucor有着密切的谱系关系。这一结果暗示目前的卷曲巴克斯霉种的概念较大,可称为广义卷曲巴克斯霉B.circina s.l.;如果仅仅依靠分子数据,很有可能给出错误的分类学鉴定结果。
