Sticholotis nanlingensis Wang & Ren sp. nov.

(Figures 92–94, 251–254, 301)

Diagnosis. This species is close to S. klapperichi in dorsal color pattern, it can be distinguished from the latter as follow: punctures on pronotum of nanlingensis slightly larger than those on elytra (Fig. 92), but punctures on pronotum in S. klapperichi are distinctly smaller than those on elytra (Mader 1955).

Description. TL: 2.44 mm, TW: 2.18 mm, TH: 1.29 mm, TL/TW: 1.12; PL/PW: 0.44; EL/EW: 0.92; HW/TW: 0.36; PW/TW: 0.62.

Head brown. Pronotum brown, scutellum dark brown. Elytra reddish brown, with moderately wide brown band along lateral margin; band expanded at middle of lateral margin and elytral apex. Elytra with 6 moderately large, black rounded spots disposed as follows: a pair resting on the humeral calli (touching basal margin); a pair resting on disc slightly posteriad of half length of elytron; one (the largest) resting on 2/5 length of elytral suture; one just before sutural apex (Figs 92–94). Underside dark brown, elytral epipleuron reddish brown. Legs yellowish brown.

Body almost circular in outline, hemispherical, shiny and glabrous. Head frontal punctures fine and shallow, 1.0–2.0 diameters apart, with short setae, interocular distance of eyes 0.55x head width (Fig. 94).

Pronotal punctures medium and dense, 0.3–0.8 diameters apart. Elytral punctures fine, smaller than those on pronotum, 1.0–2.5 diameters apart, with a row of large punctures near middle part of suture. Elytral margins moderately explanate, entirely visible from above.

Prosternal punctures inconspicuous. Mesoventral surface shining, punctures fine, 2.0–3.0 diameters apart. Metaventrite covered by coarse and dense punctures distributed at center. Elytral epipleuron moderately broad, complete to apex, foveate to accommodate femoral tips of hind legs. Wings well-developed.

Male genitalia: Penis slender, strongly curved, broadening basally, capsule with small inner process (Fig. 252); tegmen with penis guide in lateral view stout, widest at base, gradually tapering to apical 1/3, then strongly narrowed, apex pointed; distinctly longer than parameres (Fig. 253); parameres slender, almost straight, with short setae apically; penis guide in ventral view short and stout, widest at base, tapering to apex (Fig. 254).

Female genitalia: unknown.
