Abstract

A new species of Proteremaeus, P. nebaikini, is described from Khabarovsk District, Soviet Far East, on the basis of adults. Evidence is presented for considering Sibiremaetts Ryabinin and Krivolutsky. 1975 as a junior synonym of Proteremaeus Piffl, 1965 A key is given to adults of the eight known species of Proteremaeus. Extant members of this genus are known only from the Palaearctic. Thus, a recently discovered fossil specimen of this genus from the late Tertiary, from Ellesmere Island, Canada, has important biogeographic implications which are discussed.

Résumé

Une nouvelle espèce de Proteremaeus, P. nebaikini, est décrit de la région Khabarovsk de l’extrême est Soviétique, basée sur les adultes. Sibiremaeus Ryabinin et Kriyolutsky, 1975 est considéré comme un synonyme récent de Proteremaeus Piffl, 1965. L ouvrage comprend une clé des huits espèces connues. Les membres existants de ce genre sont connus seulement de la région Palaearctique. Donc, on discute les implications importantes biogéographique d’un spécimen fossil découvert récemment de l’isle Ellesmere au Canada.
