( Figs . 75, 141 , 160 )

Holotype: ♀. Amazon ( Brazil), Bates ( BMNH).

Color: Cranium mostly black, region behind eyes slightly flavotestaceous, gula flavotestaceous; pronotum mostly black, venter and upper sides flavotestaceous; mesoscutellum black; elytra black. Head: Antennal capitulum long ( Fig. 75 ), each capitular antennomere not as long as combined length of scape, pedicel, and funicle; antennal carina very prominent; EW/FW 10/15. Thorax: Pronotal anterior margin not projected at middle, side margin of disc with obtuse tubercle; PW/PL 43/43; elytral disc not strongly deflexed at sides, carina not present; EL/EW 145/35. Abdomen: Male pygidium not incised at distal margin.
