Chariodema Blanchard, 1850: 117 .

Type species

Philochlaenia virescens Blanchard, 1842 (designation: Evans 2003: 247).

Diagnosis

Body usually yellow or yellowish-brown, bright, and pronotum with or without green reflex ( Fig. 18 G ); pronotal anterior margin not beaded; pronotum−scutellum contact acutely sinuous ( Fig. 8 B ); prosternum with an anterior longitudinal carina; protibia with two external teeth and with a spur; meso- and metacoxae separate; internal area of metatarsomere V with spine-like setae; male ventrite VI with two parallel and setose carinae ( Fig. 9 A ).

Remarks

The genera Ancistrosoma , Chariodema , Faula , Manopus , Pectinosoma and Pseudopectinosoma are similar to each other. They have a sinuous pronotum−scutellum contact and meso- and metacoxae separate. Chariodema is distinguished by protibia with two external teeth and with a spur, and male ventrite VI with two parallel and setose carinae ( Fig. 9 A ).
