Diagnosis.

This species closely resembles Aspidimerus ruficrus in elytral color pattern (Figs 33, 36), but male genitalia are quite different (Figs 73-76; 79-82). It is also similar to Aspidimerus esakii in male genitalia, but can be distinguished from the latter by the elytra yellow with 7 black spots (Fig. 33), apex of penis with relatively small membranous appendage (Fig. 73), different shape of penis capsule (Figs 43, 73) and more narrowly truncate apex of penis guide in ventral view (Figs 46, 75). The spermatheca (Fig. 77) is also different from that of Aspidimerus esakii given by Sasaji (1968).

Description.

TL: 4.50-4.75mm, TW: 3.40-3.60mm, TH: 2.00-2.25mm, TL/TW: 1.32; PL/PW: 0.54-0.56; EL/EW: 1.04-1.06.

Body medium size and oval, dorsum moderately convex and pubescent (Fig. 33-35). Head dark yellow with basal margin and clypeus reddish brown, eyes black. Pronotum black, except anterior corners dark yellow (Fig. 35). Scutellum black. Elytra yellowish brown with black sutural stripe distinctly expanded near basal half (Fig. 33). Elytral margins black. Each elytron with 3 black spots arranged as Fig. 34. Underside reddish brown, except legs dark yellow.

Head small, 0.44 times elytral width (HW/EW=1:2.27). Surface of head with fine punctures, separated by 0.3-1.0 times their diameter, with thick, yellowish pubescence. Eyes large and almost oval, rather finely faceted, the widest interocular distance 0.50 times head width. Pronotum 0.71 times elytral width (PW/EW=1:1.42). Punctation on pronotum sparser than on head, separated by 1.0-1.5 times their diameter, with thick, yellowish pubescence. Surface of elytra densely pubescent and sparsely punctate, punctures separated by 0.5-2.0 times their diameter. Underside finely punctate, with pubescence dense, moderately long and yellowish.

Male genitalia: Penis relatively long, slender, curved almost in a circle. Penis capsule with a short outer process and a long inner one, apex of penis with relatively small membranous appendage (Figs 73-74). Penis guide slender, gradually tapering to apex in lateral view (Fig. 76). In ventral view, penis guide short oval, widest at base with truncate apex (Fig. 75). Parameres slender, densely setose along almost half of their length, longer than penis guide (Fig. 76).

Female genitalia: Tenth tergite broad with terminal setae. Coxites subtriangular with moderately long terminal setae (Fig. 78). Spermatheca vermiform with wide nodulus and long ramus (Fig. 77).
