Description

TL: 3.65-4.24 mm, TW: 2.72-3.31 mm, TH: 1.46-1.82 mm, TL/TW: 1.28-1.34, PL/PW: 0.46-0.51, EL/EW: 1.07-1.16.

Body oval, moderately convex. Head black, densely covered with short, greyish pubescence. Mouthparts and antenna black. Pronotum black, densely covered with short, greyish pubescence. Scutellum black. Elytra reddish-brown, with a pair of black spots at elytral apex, densely covered with short, greyish pubescence (Fig. 2 a-c). Underside black, except elytral epipleura brownish-yellow, densely covered with short, greyish pubescence. Abdominal postcoxal lines incomplete, arcuate. Posterior margin of male abdominal ventrite 5 slightly emarginate at middle and of ventrite 6 distinctly emarginate (Fig. 2 d).

Male genitalia: penis slender, penis capsule with short outer arm and long inner arm, apex of penis truncate with membranous appendage (Fig. 2 e-f). Tegmen stout, penis guide parallel along 2/3 length, then gradually narrowing to apex in ventral view; penis guide in lateral view, widest at base, parallel along 2/5 length, then gradually narrowing to apex; parameres as long as penis guide with dense long setae on the inner sides and distal end with a group of long setae in lateral view (Fig. 2 g-h).

Female genitalia: coxites distinctly elongate (Fig. 2 i). Spermatheca approximately C-shaped, cornu without appendage.

Diagnosis

This species can be easily distinguished from other species of Priscibrumus by the following combination of characters: elytra reddish-brown, with a pair of black spots at elytral apex; parameres as long as penis guide.
