Description.

Length: 7–9 mm (4 specimens measured).

Head: Dark red-brown to black; interocular space 2.4 eye widths; antennae dark red-brown, very long, clearly reaching beyond pronotal base when laid back.

Pronotum: Length to width ratio 1.0:1; brown.

Elytra: Light brown to brown, with a large dark brown basal and a large dark brown apical macula on each side.

Legs: Brown; profemora thicker than mesofemora thicker than metafemora; protibiae straight, mesotibiae bent, metatibiae almost straight, mesotibiae with a larger (but not stout) spur and a smaller spur, metatibial spurs short, almost straight, slightly bent at the tip.

Lower surface: Dark brown.

Terminal abdominal segments: Anterior margin of pygidium straight, posterior margin almost straight, lateral margins curved, pygidial arms long, medium broad and distinctly converging posteriorly; anterior margin of sixth ventrite slightly sinuous, posterior margin slightly concave, lateral margins slightly curved and converging posteriorly.

Male genitalia: Phallus shorter than tegmen, dorsal sinus deep, ventral sinus short and narrow, phallobasic struts thin, almost straight, tips acute, phallobasic apodeme medium broad and slightly dilated towards its anterior limit; phallic tip constricted towards its posterior limit, phallic plates broad, phallic struts medium broad, tips curved; spicular fork fused up to one third, spiculae slightly sinuous, with distinct thorns, tips of spiculae bent and distinctly dilated.

Distribution. India.

Seasonal occurrence. Collected in July.
