Adetaptera Santos-Silva, Nascimento and Wappes , gen. nov.

Etymology. From “ Adetus ” (genus of Apomecynini ) + aptera (wingless). Feminine gender.

Type species. Parmenonta albisetosa Bates, 1880 , here designated.

Description. Body from small to moderate-sized, cylindrical. Head retractile; frons transverse; antennal tubercles flat or slightly elevated, widely separated; eyes coarsely faceted, small, divided; lower eye lobes much shorter than gena; antennae distinctly not reaching elytral apex; scape short, slightly surpassing anterior margins of prothorax; antennomere III longer than scape; antennomere IV shorter than III; remaining antennomeres shorter than IV, decreasing in length or with similar length. Prothorax from about as long as wide to slightly longer than wide; sides unarmed; in side view, very slightly inclined toward posterior margin, not tuberculate. Procoxal cavities closed posteriorly; prosternal process distinctly, gradually widened toward apex. Metaventrite noticeably reduced ( Fig. 40 , 43 ), slightly wider than mesoventrite. Elytra from equal to very slightly wider basally than posterior area of prothorax; parallel-sided from humerus to distal quarter, then gradually rounded, or gradually widened from base to about middle, then gradually narrowed toward apex; apex rounded, slightly truncate or distinctly bispinose; in side view, dorsal surface nearly uniformly convex; without erect setae. Membranous wings absent ( Fig. 39 , 42 ). Legs short, femora gradually, slightly clavate, or almost fusiform. Abdominal ventrite V not deeply excavate posterocentrally in both sexes.

Remarks. Adetaptera gen. nov. differs from Adetus by the membranous wings absent (present in Adetus ), and by the metaventrite distinctly reduced (not so in Adetus ).

Species, besides the type species, transferred to Adetaptera : A. albosticta ( Galileo and Martins, 2003) comb. nov.; A. chapadensis (Martins and Galileo, 1999) comb. nov.; A. fulvosticta ( Bates, 1885) comb. nov.; A. insularis (Fisher, 1930) comb. nov.; A. laevepunctata ( Breuning, 1940) comb. nov.; A. lenticula (Galileo and Martins, 2006) comb. nov.; A. maculata (Martins and Galileo, 1999) comb. nov.; A. minor ( Bates, 1880) comb. nov.; A. ovatula ( Bates, 1880) comb. nov.; A. parallela ( Lameere, 1893) comb. nov.; A. punctigera (Germar, 1823) comb. nov. ( Fig. 39–40 ); A. strandiella ( Breuning, 1940) comb. nov.; A. thomasi ( Linsley and Chemsak, 1985) comb. nov.; A. wickhami (Schaeffer, 1908) comb. nov. Although A. dominicana (Galileo and Martins, 2004) is provisionally transferred to Adetaptera , it may (because of its antennal length and shape, and presence of long, erect setae of elytra) belong to another genus.

It is also possible that other species currently placed in Adetus belong to Adetaptera , and that species placed in Adetaptera belong to Adetus .
