Genitalia of Atheta frosti Bernhauer (male, lectotype of At. modiella Casey (75– 79); and female, lectotype of At. frosti (80)). 75 — median lobe, parameral view; 76 — median lobe, lateral view; 77 — apex of median lobe, parameral view; 78 — apex of median lobe, lateral view; 79 — median lobe with retracted internal sac, abparameral view; 80 — spermatheca. Scale bar 0.1 mm (77–80), 0.2 mm (75–76). Diagnosis. Atheta frosti is closely related to Palaearctic At. nigritula ( Gravenhorst, 1802 ) but differs in the shape of the male tergum 8 ( Figs. 70, 72 ), the aedeagus ( Figs. 75– 79 ) and spermatheca ( Fig. 80 ). Discussion. The types of At. frosti , At. comitata , At. gnoma , At. elota , At. insidiosa , Ps. puricula , At. candidula , At. diffisa , At. nata , At. modiella and At. vacillans are similar in external characters and in the shape of the aedeagus and spermatheca. All these names are considered to be synonyms. Distribution. Atheta frosti is widely distributed in the eastern United States ( Vermont , New Hampshire , Massachusetts , Rhode Island , New York , Pennsylvania and North Carolina ) but its distribution is poorly documented.
