Diagnosis. Atheta fenyesi can be recognized among the other species of the subgenus Dimetrota auct . by the presence of four projections at the posterior margin of the male tergum 8 ( Figs. 47, 49 ), by the distinct shape of the median lobe ( Figs. 52–54 ) (particularly the fused and expanded ostial lamellae forming a wide rhomboid sclerite on the abparameral side of the median lobe ( Fig. 54 )) and the distinct shape of the spermatheca ( Fig. 55 ).

Discussion. The types of At. fenyesi , At. querula , Dim. resima , Dim. vigilans , At. socors , Dim. immerita , Dim. incredula , Dim. opinata and Dim. cerebrosa are similar in external characters and in the shape of the aedeagus and spermatheca. All these names are considered to be synonyms.

Distribution. Atheta fenyesi is known from California.
