Diagnosis
This species is close to Aspidimerus guangxiensis and Aspidimerus birmanicus (Gorham) in dorsal coloration, but can be identified by the following characters: Penis stout and short. Penis capsule with a small inner process (Fig. 56). In ventral view, penis guide extremely broad, nearly parallel-sided at basal 6/7, then strongly and asymmetrically convergent to a pointed tip (Fig. 58). In Aspidimerus guangxiensis, penis guide widest at base, gradually narrowing to the apex, apex with a lateral hook-like process in ventral view (Fig. 54). In Aspidimerus birmanicus, penis relatively long, penis capsule with a long inner process, penis guide distinctly narrower than that of Aspidimerus matsumurai in ventral view.
Aspidimerus matsumurai is also similar to Aspidimerus laokayensis in male genitalia, but can be distinguished from the latter by its color pattern and detailed structure of genitalia.
Description
TL: 3.75–4.60mm, TW: 3.00–3.50mm, TH: 1.65–2.00mm, TL/TW: 1.25–1.31; PL/PW: 0.50–0.51; EL/EW: 0.97–1.03.
Body oblong oval, moderately convex and pubescent (Figs 24–26). Head yellow with clypeus dark brown and eyes black (Fig. 26). Pronotum black except antero-lateral corners and anterior margin yellowish brown (Fig. 26). Scutellum black. Elytra black with two round red (sometimes yellowish brown) spots (Fig. 24). Underside black, except legs and abdomen reddish brown.
Head small, 0.42 times elytral width (HW/EW=1:2.40). Punctures on frons close, separated by 0.3–0.5 times their diameter, with thin, yellow white pubescence. Eyes large and broadly oval, rather finely faceted, widest interocular distance 0.60 times head width, posterior of the eye with silver setae. Pronotum 0.73 times elytral width (PW/EW=1:1.36). Pronotal punctures similar to those on head, separated by 0.5–1.5 times their diameter, with thick silver white pubescence. Punctures on elytra slightly larger than those on pronotum, separated by 0.5–1.0 times their diameter. Prosternum coarsely punctate, with pubescence sparse, long and yellowish. Mesoventrite indistinctly punctate, with several hairs. Punctures on metaventrite fine, separated by 0.2–0.5 times their diameter, with long setae.
Male genitalia: Penis stout and short, curved at basal 1/3, gradually narrowing to the apex (Fig. 56). Apical 2/5 length of penis with membranous appendage. Penis capsule with a large outer process and a small inner one (Figs 56–57). Penis guide stout, spoon-shaped in lateral view (Fig. 59). In ventral view, penis guide very broad, nearly parallel-sided, slightly divergent apically, apical part asymmetrical, suddenly and strongly convergent to a blunted tip (Fig. 58). Parameres slender, sparsely setose at apex, slightly shorter than penis guide (Fig. 59).
Female genitalia: Tenth tergite broad, arc-shaped with terminal setae. Coxites broad, 0.4 times as long as wide, each with moderately long terminal setae (Fig. 60); spermatheca absent.
