( Figures 107–109 View FIGURES 101 – 109. 101 – 103 , 275–279 View FIGURES 275 – 284. 275 – 279 , 303 View FIGURE 303 )

Diagnosis. This species is can easily be distinguished from other Sticholotis by elytra with four large yellow spots and 16 small black spots around the margins of four yellow spots ( Figs 107–109 View FIGURES 101 – 109. 101 – 103 ), taenia-shaped apex of penis, very slender parameres and penis guide with 3 pairs of denticles at apical 1/5.

Description. TL: 2.70–2.90 mm, TW: 2.31–2.67 mm, TH: 1.42–1.45 mm, TL/TW: 1.09–1.17; PL/PW: 0.40– 0.41; EL/EW: 0.89–0.97; HW/TW: 0.33; PW/TW: 0.60.

Head reddish brown. Pronotum reddish brown, and scutellum dark brown. Elytron predominantly reddish brown, with two large yellow irregular discal spots resting one near base and one near apex, each elytron additionally with 8 small black spots around the margins of yellow spots as in Figs 107–109 View FIGURES 101 – 109. 101 – 103 . Underside brown, elytral epipleuron and legs reddish brown.

Body almost circular in outline, hemispherical, shiny and glabrous. Head frontal punctures fine and shallow, 2.0–3.5 diameters apart, with short sparse setae, interocular distance of eyes 0.63x head width ( Fig. 109 View FIGURES 101 – 109. 101 – 103 ).

Pronotal punctures very fine, 2.5–4.0 diameters apart. Elytral punctures very fine and shallow, similar to those on pronotum, 2.0–3.0 diameters apart. Elytral margins narrow, visible from above.

Prosternal punctures inconspicuous, with long sparse setae. Mesoventral surface shiny, punctures inconspicuous. Metaventrite shiny, punctures inconspicuous. Elytral epipleuron broad, complete to apex, not foveate to accommodate femoral tips of hind legs. Wings well-developed.

Male genitalia: Penis slender, capsule broadening basally and with a small inner process, apex taenia-shaped ( Fig. 276 View FIGURES 275 – 284. 275 – 279 ); tegmen with penis guide longer than parameres, in lateral view straight, widest at base, gradually narrowing to apex, with a wire-like process at apical 1/4 ( Fig. 277 View FIGURES 275 – 284. 275 – 279 ); penis guide in ventral view straight, slightly narrowed at apical 1/5, with 3 pairs of denticles, apex rounded ( Fig. 278 View FIGURES 275 – 284. 275 – 279 ); parameres extremely thin.

Female genitalia: Ovipositor elongate and narrowly triangular, styli inconspicuous, each with many long terminal setae ( Fig. 279 View FIGURES 275 – 284. 275 – 279 ).
