Diagnosis.

This species is similar to Aspidimerus ruficrus in general appearance, but can be distinguished by the stout, strongly curved penis guide in lateral view and symmetrical with obtuse apex in ventral view (Figs 71-72). In Aspidimerus ruficrus , penis guide slender, slightly straight in lateral view and vase-shaped with truncate apex in ventral view (Figs 81-82). The shape of penis is also diagnostic (Fig. 69).

Description.

TL: 4.80mm, TW: 3.60mm, TH: 1.58mm, TL/TW: 1.33; PL/PW: 0.33; EL/EW: 1.14.

Body relatively large, oval, dorsum convex and pubescent (Fig. 32). Head yellowish brown in male and reddish brown in female. Eyes black. Clypeus, mouthparts and antennae reddish brown. Pronotum black with anterior corner yellowish brown (Fig. 31). Scutellum black. Elytra yellowish brown with 3 black spots on each elytron, spot 1 subrounded, situated on humeral callus, spot 2 long oval, largest, situated on middle of elytra, spot 3 smaller, oblong, and extending to the apex confluent with the border (Figs 31-32). Lateral margins black. Underside reddish brown except prosternum, mesoventrite and metaventrite black.

Head transverse and ventrally flattened, 0.36 times elytral width (HW/EW=1:2.77). Punctures on frons moderately large, separated by 0.5-1.0 times their diameter, with short sparsely distributed setae. Eyes moderately large and finely faceted, widest interocular distance 0.62 times head width. Pronotum 0.70 times elytral width (PW/EW=1:1.43), closely covered with fine punctures associated with long dense pubescence, punctures smaller than those on head, separated by 0.5-1.5 times their diameter. Punctures on elytra very fine and close, similar to those on pronotum, with dense silver white pubescence. Prosternum coarse, with sparse long yellowish pubescence. Punctures on metaventrite moderately large, separated by 0.5-1.0 times their diameter, with dense yellowish pubescence.

Male genitalia: Penis short and stout, strongly curved at basal half, apical half with membranous appendage (Figs 69-70). Penis capsule with a large outer process and a small, unciform inner process (Fig. 69). Penis guide stout and strongly curved in lateral view (Fig. 72). In ventral view, penis guide symmetrical, widest at middle and converging gradually to a blunted tip (Fig. 71). Parameres slender, equal in length to penis guide, sparsely setose at apex (Fig. 72)

Female genitalia: Unknown.
