description: Sticholotis dadugangensis Wang & Ren sp. nov.
(Figures 47–49, 178–182, 298)
Diagnosis. This species is similar to S. formosana in dorsal color pattern, but can be distinguished from latter as follows: anterior spots on elytra touching anterior elytral margins (Fig. 47), penis very long and slender (Fig. 179), and penis guide slightly shorter than parameres (Fig. 180). In S. formosana, anterior spots on elytra do not touch anterior elytral margins (Fig. 33), penis is short (Fig. 155), and penis guide is longer than parameres (Fig. 156).
Description. TL: 2.70–2.90 mm, TW: 2.51–2.67 mm, TH: 1.38–1.48 mm, TL/TW: 1.08–1.09; PL/PW: 0.43– 0.45; EL/EW: 0.83–0.89; HW/TW: 0.23; PW/TW: 0.63.
Head reddish brown, mouthparts yellow. Pronotum and scutellum black. Elytra black, each elytron with 2 large yellowish spots, anterior spot very large, irregular, at middle of basal margin (touching margin), posterior small, 1/ 2 size of anterior spot, at apical third (Figs 47–49). Underside reddish brown, middle of meso- and metaventrite dark brown. Legs yellowish brown.
Body almost circular in outline, hemispherical, shiny and glabrous. Head frontal punctures fine and conspicuous, 1.0–2.0 diameters apart, with scattered short setae, interocular distance of eyes 0.63x head width (Fig. 49).
Pronotal punctures fine and conspicuous, 1.5–2.5 diameters apart. Elytral surface polished, punctures very fine and shallow, smaller than those on pronotum, 2.0–4.0 diameters apart. Elytral margins moderately wide, hardly visible from above.
Prosternal surface mat and shagreened, punctures inconspicuous, with scattered long setae. Mesoventral surface shiny, punctures coarse and sparsely distributed with scattered short setae. Metaventrite with large and densely distributed punctures, 1.2–2.0 diameters apart. Elytral epipleuron broad, complete to apex, feebly foveate to accommodate femoral tips of hind legs. Wings well-developed.
Male genitalia: Penis long and slender, strongly curved, capsule broadening basally and with a small inner process (Fig. 179); tegmen with penis guide slightly longer than paramere, in lateral view thin and straight, arcuately projected at base(Fig. 180); penis guide in ventral view parallel along 7/8 its length, then narrowing to apex (Fig. 181); parameres long and slender.
Female genitalia: Ovipositor elongate and narrowly triangular, styli inconspicuous (Fig. 182).
Holotype: 1male, China, Yunnan: Dadugang, Puer, [22°22.35′N, 100°56.68′E], ca 950m, 26.iv.2008, Wang XM leg (SCAU); Paratype (1): 1female, same data as holotype.
Distribution. China: Yunnan.
Etymology. The specific epithet is named after Dadugang, the type locality of this ladybird.
