Agaocnemis Moser, 1918

Type species

Agaocnemis pruina Moser, 1918: 115 (designation: monotypy).

Diagnosis

Anterior and posterior pronotal margins not beaded ( Fig. 2 A ), posterior margin prominent with a medial tooth ( Fig. 2 A ); prosternum anteriorly concave (similar to Fig. 12 K ); protibia with three external teeth and without spur ( Fig. 2 A ); male protarsomeres I–II ventrally flattened and with a setal comb ( Fig. 2 A ); elytral striae indistinct, lateral margins beaded, posterior and posterointernal margins not beaded ( Fig. 1 A ); male metatibia internodistally flattened ( Fig. 2 E ); metatarsomere V without internoproximal spine-like setae; abdomen with intersegmental membrane VII–VIII concealed ( Fig. 1 A ).

Remarks

The genera Agaocnemis , Byrasba , Hamatoplectris and Hieritis have a distinct pronotal posterior lobe bearing a small medial tooth that extends over the scutellum ( Fig. 2 A–D). Agaocnemis is distinguished as follows (opposition to 1, Byrasba ; 2, Hamatoplectris ; 3, Hieritis ): male metatibia internodistally flattened ( Fig. 2 E ) (1, 3, without flattened area or teeth ( Fig. 2 F ); 2, male metatibia with an internodistal tooth ( Fig. 2 G )), and female elytron with posterolateral margin broadly beaded ( Fig. 1 B ) (1, 3, female elytral margin finelly beaded; 2, female not known).
