( Figures 68–70 View FIGURES 65 – 73. 65 – 67 , 211–216 View FIGURES 206 – 216. 206 – 210 , 299 View FIGURE 299 )

Diagnosis. This species can be distinguished from other Sticholotis species by the penis with contorted apical part and pointed apex, rather thin and slender parameres and straight penis guide ( Fig. 68 View FIGURES 65 – 73. 65 – 67 ).

Description. TL: 2.11–2.47 mm, TW: 1.88–2.21 mm, TH: 1.15–1.32 mm, TL/TW: 1.11–1.12; PL/PW: 0.39– 0.42; EL/EW: 0.89–0.90; HW/TW: 0.34; PW/TW: 0.61.

Head yellowish brown. Dorsal color pattern as follows ( Figs 68–70 View FIGURES 65 – 73. 65 – 67 ): Elytra predominantly yellowish brown, with moderately wide reddish brown band along lateral margins; band expanded at middle of lateral margin and elytral apex. Elytra with 6 moderately black rounded spots disposed as follows: two resting near middle of elytral suture, the remaining four spots slightly larger, concentrated in the apical and basal halves of each elytral disc. Sometimes spots on elytra small, external margin bands and spots besides central suture disappear. Underside reddish brown; metaventrite black brown. Legs yellowish brown and tarsi yellow.

Body almost circular in outline, hemispherical, shiny and glabrous. Head frontal punctures inconspicuous, with short sparse setae, interocular distance of eyes 0.61x head width ( Fig. 70 View FIGURES 65 – 73. 65 – 67 ).

Pronotal punctures fine and densely distributed, 1.0–2.0 diameters apart. Elytral punctures slightly larger than those on pronotum, 1.5–2.5 diameters apart, with row of large dark punctures along sutural, lateral margins. Elytral margins moderately explanate, entirely visible from above.

Prosternal punctures inconspicuous, with scattered long setae. Mesoventral surface shiny and slightly shagreened, with sparse short setae. Metaventrite covered by coarse and sparse punctures. Elytral epipleuron moderately broad, complete to apex, feebly foveate to accommodate femoral tips of hind legs. Wings welldeveloped.

Male genitalia: Penis short and slender, slightly curved at base, capsule broadening basally and with small inner process, apex pointed, contorted and curved ( Figs 212–213 View FIGURES 206 – 216. 206 – 210 ); tegmen with penis guide slightly longer than parameres, in lateral view short and stout, subparallel to apical 2/3, strongly narrowing to apex ( Fig. 214 View FIGURES 206 – 216. 206 – 210 ); penis guide in ventral view elongate, subparallel, strongly narrowed at apical 1/5, apex rounded ( Fig. 215 View FIGURES 206 – 216. 206 – 210 ); parameres slender, almost straight, with short setae apically.

Female genitalia: Ovipositor elongate and narrowly triangular, styli inconspicuous, each with several long terminal setae ( Fig. 216 View FIGURES 206 – 216. 206 – 210 ).
