Pentilia Mulsant

Pentilia Mulsant 1850: 502 ; Crotch 1874: 199; Korschefsky 1931: 223: Blackwelder 1945: 450; Gordon 1971: 185.

Type species. Pentilia egena Mulsant , by subsequent designation of Crotch (1874).

Description. Cryptognathini with frons narrow, anterior margin of clypeus emarginate medially, apical 1/4 curved upward ( Fig. 116 ). Antenna with 9 articles, club apparently with 3 articles; maxillary palpus with last article widened apically. Epipleuron strongly descending externally ( Fig. 117 ). Prosternum not widened anterior to coxae, not completely concealing mouthparts in repose ( Fig. 118 ) Proleg with tibia expanded for reception of tarsus, 2/3 width of femur, femur notched for reception of tibia; meso- and metatibia less strongly expanded, grooved on outer margin for reception of tibia. Abdomen with postcoxal line on basal ventrite incomplete, reaching nearly to lateral margin of ventrite. Female genital with stylus and stiff setae, spermatheca curved.

Remarks. Pentilia is defined by key characters. It is most similar to Curticornis Gordon but differs from that genus by an upturned clypeal apex and strongly descending epipleuron. Gordon and González are authors of all taxa here described.
