Men Q.-L., Starkevich P., He L.-F., Shi J.-X., Shi M.-Y., Zhang Z.-X., Hu J.-H., Chen A., Zhang Y.-X.Tipula (Vestiplex) from Yunnan and Tibet, China: one new species and redescriptions of five known species (Diptera: Tipulidae)Acta Entomologica Musei Nationalis Pragae 61(2): 341-362
Abstract: A new crane fly species Tipula (Vestiplex) lushuiensis Men & Starkevich, sp. nov., is described and illustrated based on materials collected in Yunnan and Tibet, China. Tipula (V.) alyxis Alexander, 1963, T. (V.) guibifida Yang & Yang, 1992, T. (V.) himalayensis Brunetti, 1911, T. (V.) quasimarmoratipennis Brunetti, 1912 and T. (V.) reposita Walker, 1848 are redescribed and illustrated based on additional morphological characters. Tipula (V.) quasimarmoratipennis and T. (V.) reposita are listed as new records for the Chinese fauna. Male of T. (V.) quasimarmoratipennis and females of T. (V.) alyxis, T. (V.) guibifida and T. (V.) himalayensis are illustrated for the first time.Published online: 22nd September 2021
Grebennikov V. V., Anderson R. S. Yagder serratus, a new eyeless weevil from Mexico and the non-monophyly of Brachycerinae, the evolutionary twilight zone of true weevils (Coleoptera: Curculionidae)Acta Entomologica Musei Nationalis Pragae 61(2): 363-374
Abstract: We describe and illustrate a new eyeless weevil, Yagder serratus gen. & sp. nov., based on a single adult female collected by sifting forest leaf litter in Mexico. A phylogenetic analysis of 39 terminals and 2679 aligned positions from three DNA fragments places the new species into the subfamily Brachycerinae (as incertae sedis) and outside the highly diversified clade of ‘higher’ true weevils. Neither Brachycerinae, nor its tribe Raymondionymini traditionally uniting most eyeless weevils, are monophyletic unless the latter is limited to a Mediterranean core group. Both these taxa are taxonomic dumping-grounds likely containing species-poor sisters of species-rich clades. When resolved, the subfamily Brachycerinae will be likely split into two or more species-poor deeply-divergent subfamilies. Published online: 22nd September 2021
