Key to Russian species of Peronomerus

1. Fourth pro-, meso- and metatarsomeres in both sexes more shallowly emarginated apically, with apical angles not forming long lobes ( Figs 2–6 ). Dorsum black, with a golden shine ( Figs 1, 2 ). Median lobe of aedeagus sharply bent at middle ( Fig. 14 ) and with a very large narrow sclerotized process in internal sac ( Figs 29, 30 ) ....... P. auripilis

– Fourth pro-, meso- and metatarsomeres in both sexes deeply emarginated apically ( Figs 8– 12 ), with apical angles forming long lobes (about a third of length of corresponding fifth tarsomeres). Dorsum black, without a golden shine ( Figs 7, 10 ). Median lobe of aedeagus more strongly arcuate ( Fig. 19 ), without a large sclerotized process in internal sac ( Figs 31, 32 ) ................................................................................................................
