ABSTRACT. Polypedilum (Uresipedilum) alixae sp.n., is described based on material recently collected using Malaise traps placed close to cold acidic peat bogs located in the Nature Reserve of Machais (Vosges region, NE-France). Based on some distinctive characters found in the male adult (basal part of segment VIII triangular; shape of tergite IX, anal point, superior volsella and gonostylus), P. alixae sp.n. keys to the subgenus Uresipedilum Sasa and Kikuchi, 1995 and appears to belong to a local biogeographic element. On the basis of some additional characters for the subgenus, a complemented subgeneric diagnosis of the male adult is given with reference to previous information from the literature. Currently, the subgenus Uresipedilum is represented by five species in France: P. bernardae Moubayed-Breil, 2020; P. claudei Moubayed-Breil, 2020; P. convictum (Walker, 1856); P. cultellatum Goetghebuer, 1931; P. tissoti, Moubayed-Breil and Langton, 2019. Consequently, the description of P. alixae sp.n. increases the total number in the genus to six from this country. The new species is known only from its type-locality in NE-France. Discussion, differential diagnosis and comments on the ecology and geographical distribution of the new species are given.
KEY WORDS: Diptera, Chironomidae, Polypedilum, subgenus Uresipedilum, new species, NE-France.
