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.

Two new genera (Cataglyphoides gen. nov. and Conoformica gen. nov.) and six new species (Cataglyphoides intermedius sp. nov., Conoformica bitterfeldiana sp. nov., Formica kutscheri sp. nov., F. palaeopolonica sp. nov., F. radchenkoi sp. nov., F. zherikhini sp. nov.) are described. A new combination, Cataglyphoides constrictus (Mayr, 1868), comb. nov., is established. A lectotype of Camponotus constrictus Mayr, 1868 and a neotype of Formica phaethusa Wheeler, 1915 are designated. Formica clymene Wheeler, 1915 is recognized as a new synonym of F. phaethusa Wheeler, 1915. An identification key for workers of Formicini species from Late Eocene European ambers is provided.     

Brachyceran Diptera (Insecta) in Cretaceous ambers, Part IV, Significant New Orthorrhaphous Taxa

Thirteen species of basal Brachycera (11 described as new) are reported, belonging to nine families and three infraorders. They are preserved in amber from the Early Cretaceous (Neocomian) of Lebanon, Albian of northern Spain, upper Albian to lower Cenomanian of northern Myanmar, and Late Cretaceous of New Jersey USA (Turonian) and Alberta, Canada (Campanian). Taxa are as follows, with significance as noted: In Stratiomyomorpha: Stratiomyidae (Cretaceogaster pygmaeus Teskey [2 new specimens in Canadian amber], Lysistrata emerita Grimaldi & Arillo, gen. et sp. n. [stem-group species of the family in Spanish amber]), and Xylomyidae (Cretoxyla azari Grimaldi & Cumming, gen. et sp. n. [in Lebanese amber], and an undescribed species from Spain). In Tabanomorpha: Tabanidae (Cratotabanus newjerseyensis Grimaldi, sp. n., in New Jersey amber). In Muscomorpha: Acroceridae (Schlingeromyia minuta Grimaldi & Hauser, gen. et sp. n. and Burmacyrtus rusmithi Grimaldi & Hauser gen. etsp. n., in Burmese amber, the only definitive species of the family from the Cretaceous); Mythicomyiidae (Microburmyia analvena Grimaldi & Cumming gen. et sp. n. and Microburmyia veanalvena Grimaldi & Cumming, sp. n., stem-group species of the family, both in Burmese amber); Apsilocephalidae or near (therevoid family-group) (Kumaromyia burmitica Grimaldi & Hauser, gen. et sp. n. [in Burmese amber]); Apystomyiidae (Hilarimorphites burmanica Grimaldi & Cumming, sp. n. [in Burmese amber], whose closest relatives are from the Late Jurassic of Kazachstan, the Late Cretaceous of New Jersey, and Recent of California). Lastly, two species belonging to families incertae sedis, both in Burmese amber: Tethepomyiidae (Tethepomyia zigrasi Grimaldi & Arillo sp. n., the aculeate oviscapt of which indicates this family was probably parasitoidal and related to Eremochaetidae); and unplaced to family is Myanmyia asteiformia Grimaldi, gen. et sp. n., a minute fly with highly reduced venation. These new taxa significantly expand the Mesozoic fossil record of rare and phylogenetically significant taxa of lower Brachycera.

Styloconops hamariensis n. sp. in Somalia (Diptera, Ceratopogonidae)

A new species of the genus Styloconops (S. hamariensis n. sp.) is described on material collected in Somalia in the coastal area near Mogadiscio. This ceratopogonid midge is common during the rainy seasons and it has been observed biting on man and cattle. The new species is morphologically similar to S. spinosifrons from which it can be clearly differentiated for at least some diagnostic characters both in the female and male adults.     

Characteristics of Culicoides (Diptera, Ceratopogonidae) breeding places near Salisbury, Rhodesia

Abstract. 1. A survey of Culicoides breeding places was made around Salisbury. Out of forty species caught in light traps, only nineteen were reared from breeding places.
2. The seven most abundant species with their characteristic sites were C.pycnostictw in mud around water bodies, especially dams; C.nivosus very prevalent around puddles rich in organic matter: C. distinctipennis along drainage canals intermediate in organic matter; C.gulbenkiani in cow dung especially on damp soil; Caccraensis gp. only in rot holes and tree forks; Cschultzei gp. along streams and drainage canals in mud rather poor in organic matter; C.tropi-calis in drainage canals very low in organic matter; C.imicola possibly breeds widely dispersed mainly in a rich mixture of organic matter and damp soil, with cow pats and edges of water bodies being marginal.
3. The prevalent species are believed to breed all year round. Preponderance of females in the breeding places was found in C.pycnostictus, C.nivosus and C.accraensis gp. while the reverse was true in C.distinctipennis and C.gulbenkiani. The preponderance of males as indication of proximity to breeding sites is thus probably questionable.     

Gonotrophic cycle of Leptoconops borealis (Diptera, Ceratopogonidae)]

Data are given concerning the gonotrophic cycle in fully engorged specimens of Leptoconops borealis, a mass blood sucker from the coast of the sea of Azov. In fully engorged females the repetition of gonotrophic cycles and degeneration of ovaries take place under the effect of Mermitoidea parasitism.     

First report of Culicoides boyi (Diptera: Ceratopogonidae) in France

Culicoides boyi Nielsen, Kristensen & Pape 2015 (Diptera: Ceratopogonidae), described in Denmark in 2015, is reported in France. This species is closely related to Culicoides pulicaris (Linnaeus 1758) and can only be distinguished from this species by a subtle variation in spot wing pattern and by calculation of maxillary palpal ratio.
