Sticholotis hirashimai Sasaji

(Figures 17–19, 129–133, 295)

Sticholotis hirashimai Sasaji, 1967: 14; Ren et al., 2009: 32.

Diagnosis. This species can be distinguished from other Chinese species of Sticholotis by dark brown body without spots (Figs 17–19). The male genitalia of this species are very distinctive because of very large penis basal capsule and penis guide with a pair of distinct lamellate processes at basal 2/5 length (Figs 130–132).

Description. TL: 2.47–2.77 mm, TW: 2.24–2.57 mm, TH: 1.35–1.48 mm, TL/TW: 1.08–1.10; PL/PW: 0.43– 0.45; EL/EW: 0.87–0.90; HW/TW: 0.35; PW/TW: 0.67.

Body uniformly saddle brown, except legs yellowish brown; almost circular in outline, hemispherical, shiny and glabrous (Figs 17–19). Head frontal punctures shallow and inconspicuous, with scattered short setae. Interocular distance 0.67x head width (Fig. 19).

Pronotal punctures fine and sparsely distributed, 1.5–2.5 diameters apart. Elytral punctures very fine and sparsely distributed, slightly larger than those on pronotum, 1.5–3.0 diameters apart. Lateral margins of elytra very narrow, hardly visible from above.

Prosternum with inconspicuous punctures and scattered long setae. Mesoventral punctures coarse, 0.2–1.0 diameters apart, with short sparsely distributed setae. Central disc of metaventrite covered by coarse and dense punctures. Elytral epipleuron broad and complete to apex, feebly foveate to accommodate femoral tips of hind legs. Wings well-developed.

Male genitalia. Penis slender, basal capsule very large, apex with thin and arcuate sclerotized appendage and membranous appendage (Fig. 130); tegmen with penis guide slightly longer than parameres, in ventral view spindle-shaped, relatively broad with weakly swollen sides at basal 2/3 and then strongly narrowing towards apex (Fig. 132), in lateral view thin and straight, with pair of distinct lamellate processes present at basal 2/5 length (Fig. 131); parameres long and slender.

Female genitalia. Ovipositor elongate; coxites narrowly triangular, styli inconspicuous, each with sparse long terminal setae (Fig. 133).
