( Figs. 42–43 )

Description

Male. Black. Pronotum, scutellum and elytra dark red.

Head slightly convex and feebly grooved behind antennal prominence. Eyes relatively small (interocular distance about 4 times as long as the radius). Ultimate joint of maxillary palpi parallel­sided and about 2 times longer than palpomere 3. Antennae slightly reaching over elytral two thirds, with antennomere 3 and following antennomeres subequal in length to each other and about 1.3 times longer than scape.

Pronotum slightly transverse, 1.1 times wider than long, trapezoidal, with conspicuous median carina in anterior half; hind angles acuminate and produced latero­posteriorly. Scutellum square, almost parallel­sided, slightly rounded and feebly emarginate at apex. Elytra long, 3.25 times longer than wide humerally, slightly widening posteriorly, not dehiscent. Dense pubescence short and decumbent.

Metatrochanters with blunt posterior angles.

Aedeagus with relatively small hood of the median lobe ( Figs. 42–43 ).

Length: 9.0 mm. Width (humerally): 2.2 mm.

Female. Unknown.
