查看更多>>摘要：The subfamily Pantheinae is diagnosed. The genus Trisuloides Butler, 1881 of the subfamily Pantheinae is revised. Three new species {Trisuloides xizanga sp. n., T. becheri sp. n. and T. prosericea sp. n) are described from China as new. The name Trisuloides catocalina Moore, 1883 stat. rev. is recognized as valid, not a synonym of Trisuloides sericea Butler, 1881 and not a homonym of Tambana catocalina Moore, 1882 (currently placed in Antitrisuloides Holloway, 1985). The name Trisuloides luteifasciaHampson, 1894 is recognized as a junior synonym (syn. n.) of Trisuloides catocalina Moore, 1883. A key for identification of Trisuloides species based on genitalia characters is provided. The monotypic genus Dis-epholcia, which is closest to Trisuloides,is reviewed.
查看更多>>摘要：The Tanypodinae from Lake Winnipeg, Manitoba, Canada are listed and taxonomic and ecological notes given. The males of Paramerina fragilis (Walley) mdHelopelopiapilicaudata (Walley), and the immatures of Telopelopia okoboji (Walley) are redescribed. The larvae of cf. Conchapelopia currani (Walley) and cf. Helopelopia pilicaudata are described.
查看更多>>摘要：The immatures and males of A. (Karelia) illinoensis (Malloch), A. (K.) philosphagnos Beck e^Beck, A. (K.) pulchripennis (Lundbeck), A. (A.) mallochi (Walley), A. (A.) aspera Roback, A. (A.) basalis (Walley) and A. (Asayia) annulata (Say) are redescribed and/or illustrated. A. (A.) basalis (Walley) is regarded as a valid species separate from Nearctic A. (A.) monilis auct nec (L.). Seven species of Ablabesmyia were found from Lake Winnipeg, Manitoba, 3 from Marion Lake, British Columbia while other samples from Alberta to Ontario contained no more than one species. Keys are given to Nearctic immatures of Ablabesmyia. The distribution of Ablabesmyia in Lake Winnipeg is mapped and discussed. The separation of larval instars is shown approximately to follow Dyar's rule.
查看更多>>摘要：Tanytarsus fereci sp. nov. is described from a specimen found in Eocene Baltic amber. The new species is compared with the fossil Tanytarsus serafini Gilka and with the extant T. aculeatus Brundin. Following the analysis of morphological diagnostic characters, T. fereci is placed in the mendax species group.
