Diagnosis. Atheta klagesi can be recognized by the following combination of characters: head and abdominal terga 5–6 black; pronotum, abdominal terga 3–4 and 7–8, and antennal articles 4–11 or 3–11 brown; elytra yellow with vaguely defined darker areas around scutellum and in postero­lateral angles; antennal articles 1–2 or 1–3, legs and mouthparts yellow; antennal articles 5–10 strongly transverse, article 10 twice as wide as long; pronotal pubescence of type V ( Benick & Lohse 1974 ); mesotibial macrosetae thin, as long as tibial width; posterior margin of male tergum 8 convex and crenulate ( Figs. 93, 95 ); aedeagus as in Figs. 99–102 ; and spermatheca as in Fig. 98 . FIGURES 98–102. Genitalia of Atheta klagesi Bernhauer (male, lectotype of At. klagesi (99–102); and female, paralectotype of At. nympha Casey (98)). 98 — spermatheca; 99 — median lobe, parameral view; 100 — apex of median lobe, parameral view; 101 — median lobe, lateral view; 102 — apex of median lobe, lateral view. Scale bar 0.1 mm (98, 100, 102), 0.2 mm (99, 101). Discussion. The types of At. klagesi , At. cephalina , At. nympha , At. discreta , Ps. dissensa and At. villica are similar in external characters and the shape of the aedeagus and spermatheca. All these names are considered to be synonyms. Atheta cephalina is the type species of the subgenus Delphota Casey, 1910a by original designation. Pseudota dissensa is the type species of the genus Pseudota Casey, 1910a by original designation (Casey first species rule). Casey did not specifically state in his description of Pseudota that Ps. dissensa was the type species of Pseudota ; however, while designating the type species of Noverota Casey, 1910a in the same paper, Casey stated (1910a, p. 90): “The first species may be regarded as the type , as in all other cases where the type is not specifically named”. Since both At. cephalina and Ps. dissensa are synonyms of At. klagesi , the names Delphota and Pseudota are subjective synonyms of each other, irrespective of what subgenera in the genus Atheta are accepted as valid. The problem of subgeneric placement of At. klagesi within Atheta is outside the scope of the present paper. The matter will be addressed in a separate work when the generic revision of the tribe Athetini is completed. Distribution. Atheta klagesi is known from the eastern United States ( Minnesota , Iowa, Pennsylvania, New Jersey, New York, Maine) and eastern Canada ( Québec ).
