Diagnosis. This species is similar to Aspidimerus matsumurai Sasajiin elytra with two spots (Figs 21, 24), but can be distinguished from the latter by its smaller size and unique male genitalia: penis short, apical 1/2 length with membranous appendage (Fig. 53), penis guide extremely broad, widest at base, gradually narrowing to the apex, apex with a lateral, hook-like process in ventral view (Fig. 54). In Aspidimerus matsumurai ,penis short, apical 2/5 length with less membranous appendage (Fig. 56), penis guide broad in ventral view, nearly parallel-sided at basal 6/7, then strongly and asymmetrically convergent to a pointed tip (Fig. 58). Description. TL: 2.75-2.80mm, TW: 2.25-2.30mm, TH: 1.55-1.65mm, TL/TW: 1.25-1.30; PL/PW: 0.50-0.55; EL/EW: 0.91-1.11. Body small, oval, moderately convex, dorsal surface pubescent (Figs 21-23). Head yellow or reddish brown with eyes black (Fig. 23). Pronotum black, with basal margin reddish brown and anterior corners yellowish brown. Scutellum and elytra black. Each elytron with one yellowish brown spot, rounded, situated at the middle of elytron (Fig. 21). Underside dark brown, except legs and abdomen reddish brown. Head small, 0.44 times elytral width (HW/EW=1:2.25). Punctures on frons fine, separated by 1.0-2.0 times their diameter, with short silver white setae. Eyes small, broadly oval, widest interocular distance 0.55 times head width (Fig. 20). Pronotum 0.67 times elytral width (PW/EW=1:1.50). Pronotal punctures fine, separated by 1.0-3.0 times their diameter. Scutellum triangular. Punctures on elytra slightly larger than those on pronotum, separated by 1.0-2.0 times their diameter. Prosternum coarse, with sparse punctation and long pubescence. Mesoventrite small, with a few setae. Metaventrite densely pubescent with punctures large and closely spaced, separated by 0.5-1.0 times their diameter. Male genitalia: Penis short and stout. Penis capsule with a distinctly outer process and a long inner one (Fig. 53). Penis guide widest at base and abruptly constricted forming a pointed apex in lateral view (Fig. 55). In ventral view, penis guide flat and asymmetrical, widest at base, gradually narrowing to the apex, apex with a lateral, hook-like process (Fig. 54). Parameres slender, sparsely setose at apex, shorter than penis guide (Fig. 55). Female genitalia: Unknown. Specimens examined.
