	abstract = {<p>The distribution of Acomopterella species in the Palaearctic region has been re-examined in this study, using recently collected material. The European species was found to be distributed in the eastern Palaearctic as well. A second Palaearctic species from Honshu (Japan) is herein described. The morphology of adult specimens was studied by light microscopy and scanning electron microscopy. The shape of functional specialized setae on mid tibiae in Acomopterella and seven further fungus gnat genera is described and the suitability of this character for systematic studies is discussed. Details of a \&ldquo;hind tibial organ\&rdquo; are described.The position of Acomopterella in the tribe Gnoristini is briefly discussed. Acomopterella is found to be more closely related to Speolepta Edwards, 1925, than to any other recent genus.</p>

	abstract = {The genus Katatopygia gen. n. is proposed for the Boletina erythropyga/punctus-group that was first introduced by Garrett (1924, 1925) and currently comprises eight described species. Molecular studies have strongly indicated that this group forms a monophyletic sister-group to a clade consisting of all other Boletina, Coelosia and Gnoriste, and its monophyly is supported by morphological data as well. The new genus includes the following species: Katatopygia antoma (Garrett, 1924), comb. n., Katatopygia antica (Garrett, 1924), comb. n., Katatopygia erythropyga (Holmgren, 1883), comb. n., Katatopygia hissarica (Zaitzev \& Polevoi, 2002), comb. n., Katatopygia magna (Garrett, 1925), comb. n., Katatopygia laticauda (Saigusa, 1968), comb. n., Katatopygia neoerythropyga (Zaitzev \& Polevoi, 2002), comb. n. and Katatopygia sahlbergi (Lundstr{\"o}m, 1906), comb. n., all transferred from Boletina. K. sahlbergi is found to be a senior synonym of Boletina punctus Garrett, 1925, syn. n. A phylogeny based on morphological data and using parsimony analysis yielded four most parsimonious trees where the new genus is retrieved as monophyletic with high support. Katatopygia neoerythropyga is found to be the sister-taxon to all other species that form two clades, one with K. sahlbergi-like species and one with K. erythropyga-like species. A key to males of Katatopygia is provided. },

	abstract = {<p> Six new species are described, raising the number of North American Acomoptera species to seven and the genus total to ten, and nearly doubling the number of species within the putative clade containing Acomoptera, Drepanocercus, and Paratinia. These novel species forms have implications for the concept of Acomoptera that in turn, may impact our understanding of its generic relationships and the evolution and composition of Gnoristinae and Sciophilinae. The new species, A. crispa, A. digitata, A. echinosa, A. forculata, A. nelsoni, and A. vockerothi, are compared with the type species of the genus, A. plexipus (Garrett), whose diagnostic features are imaged and illustrated for the first time. The European species, A. difficilis (Dziedzicki) is also illustrated and compared. Acomoptera spinistyla (S\&oslash;li) comb. nov is transferred from Drepanocercus. A key to species is provided. Future work will seek to incorporate this knowledge into a systematic phylogenetic study of relationships between these species and their sister taxa. </p>},
