Urytalpa nigrita (Johannsen, 1910)

MATERIAL. 4 ♂♂, Ladannah, 4– 15.07.1999 ( FRIP) .

DISTRIBUTION. Nearctic, known by two specimens from USA and Canada [ Kjaerandsen et al., 2009]. Here for the first time recorded from the Palaearctic region and Russia. REMARKS. Taimyr specimens ( Fig. 2 ) have minor differences in the basal part of the male aedeagal apparatus (e.g. presence of additional basal appendages), comparing with Canadian specimen, figured by Kjaerandsen et al. [2009]. We, however, believe they are conspecific, considering the general similarity of terminalia and especially characteristic apex of aedeagus, forming four small projections [cf. Kjaerandsen et al. 2009, p. 45, Fig. 9 A ]. There are 3 other specimens in the series with slightly different structure of male terminalia ( Fig. 3 ), and probably representing distinct species somewhat more similar to U. rhapsodica Chandler, 1995 .
