Three recent genera are included in the supertribe Stomatosematidi: Stomatosema (16 species), Vanchidiplosis (4 species), and Didactylomyia (3 species). Seven species of the genus Stomatosema and two species of the genus Vanchidiplosis occur in the Palaearctic. The reliable findings of representatives of the supertribe were not known in fossilized condition. One new genus and 3 new species are described from amber of the Late Eocene age (Rovno region): Stomatosema iljieteugeniae sp. n., Clarumreddera korneyevi gen. n. et sp. n. and C. conceptiva sp. n.


One new genus and two new species are described from an amber sample of the Late Eocene age (Rovno district, Ukraine): Didactylomyia dlusskyi sp.n., Rovnodidactylomyia zosimovichi gen. n. et sp. n., R. sidorenkoi sp. n. and R. iconica sp. n. Two species from a Baltic amber sample of the Late Eocene age described earlier (Bryocrypta - R. girafa (Meunier 1904) comb. n. and R. capitosa (Meunier 1904)) were referred to the genus Rovnodidactylomyia. The genus Didactylomyia at the fossil condition was described for the first time; two contemporary Palaearctic species are reported. Keys to the species of the genus Didactylomyia are given.

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. © Pleiades Publishing, Ltd., 2009.

Optimum temperature and plant growth conditions for the development of Diuraphis noxia (RWA) (Kurdjumov) (Rhynchota Aphididae) exist in spring barley. Our experiments showed that approximately 42% of barley tillers were damaged, compared to 6% of winter wheat tillers and 1% of spring wheat tillers. Relative resistance productive tillers infested with RWA to this pest was observed in hulled barley and acceptance in hulless winter and spring bread wheat. Awnless wheat was more resistant to RWA than awned wheat. The reduction of grain number and weight per spike, 1000-grain weight in productive tillers infested with of RWA was in winter wheat 48, 82 and 33%, spring wheat 55, 65 and 23%, in barley 23, 37 and 16%, respectively. Yield losses were estimated to 18.6% for barley, 5.9% for winter wheat and 0.7% for spring wheat.

The new genus Groveromyia gen.n is described from the Late Eocene Rovno amber. It includes 3 new species - G. occlusa sp. n., G. digna sp. n., G. astrosa sp. n., and G. concinna (Fedotova, 2005) comb. n. (Bryocrypta). Some changes in biometric parameters of the genera and species were revealed in the comparison of the modern and Late Eocene Stomatosematidi. Keys for the identification of modern and fossil genera of the tribe Stomatosematidi and species of the genus Groveromyia are given.

A new bristletail species, Pedetontus phuketi sp. n., is described from Phuket Island, Thailand. It is most similar to P. hainanensis Yu, Zhang W.-W. et Zhang J.-Y., 2010 described from Hainan Island (China). The genus Pedetontus comprises 33 described species in two subgenera: Pedetontus s. str. (6 species) and Verhoeffilis (27 species). The subgenus Verhoeffilis has originated in the southeastern part of the Palaearctic Region. Its representatives migrated to North America in the Paleocene through the Bering Land Bridge which was sunken in the Eocene, so that the Nearctic centre of Pedetontus speciation became isolated and the subgenus Pedetontus s. str. has been formed. The Bering Land Bridge was formed at the end of the Miocene, and the backward migration of bristletails of the subgenus Pedetontus s. str. from the Nearctic to the Palaearctic occurred. Pedetontus palaearcticus was formed on Kamchatka. The southward migration of bristletails of the subgenus Verhoeffilis has led to formation of 10 Indo-Malayan species. © 2013 Pleiades Publishing, Inc.


A new bristletail species, Pedetontinus kabaki sp. n., is described from Sichuan Province, China. It possess faceted eyes clearly longer than wide, with the contact line shorter than 0.5, paired ocelli relatively closer to each other, and fore femur swollen. A key to 18 described species of the world fauna is given. The plesiomorphic and apomorphic states of 13 characters of Pedetontinus are considered; the phylogenetic relationships of species are discussed. © 2015, Pleiades Publishing, Inc.
