( Figures 29–31 View FIGURES 29 – 37. 29 – 31 , 150–153 View FIGURES 150 – 158. 150 – 153 , 296 View FIGURE 296 )

Diagnosis. This species can be distinguished from other species of Sticholotis by relatively flat body, unique elytral color pattern and pronotum with dense short pubescence ( Figs 29–31 View FIGURES 29 – 37. 29 – 31 ).

Description. TL: 2.27 mm, TW: 2.01 mm, TH: 0.86 mm, TL/TW: 1.13; PL/PW: 0.41; EL/EW: 0.82; HW/TW: 0.34; PW/TW: 0.61.

Head dark brown, with mouthparts brown. Pronotum black, anterior margin and lateral sides usually narrowly and obscurely reddish brown. Scutellum black. Elytra dark brown, with narrow reddish brown lateral margins, each elytron with a large irregular C-shaped spot, like a flame ( Figs 29–31 View FIGURES 29 – 37. 29 – 31 ). Underside dark brown.

Body almost circular in outline, hemispherical, shiny and glabrous. Head frontal punctures medium and densely distributed, 0.5–1.0 diameters apart, with short sparse setae. Eyes small and coarsely faceted, interocular distance 0.62x head width ( Fig. 31 View FIGURES 29 – 37. 29 – 31 ).

Pronotal surface shining and slightly shagreened, punctures medium and conspicuous, 0.5–1.5 diameters apart, slightly smaller than those on head, covered with short densely distributed pubescence. Elytral surface polished, punctures medium, similar to those on pronotum, 1.0–1.5 diameters apart, with two arcuate rows of large punctures on mid suture. Elytral margins very wide, visible from above.

Prosternal punctures inconspicuous, with scattered long setae. Mesoventral intercoxal process transverse, anterior margin feebly emarginate, punctures large, 0.5–1.0 diameters apart. Metaventrite broad and slightly shagreened, covered by large and dense punctures distributed at center, separated by 0.5–1.0 diameters, fine and sparsely in lateral side. Elytral epipleuron broad, complete to apex, very feebly foveate to accommodate femoral tips of hind legs. Wings well-developed.

Male genitalia: Penis slender, penis capsule broadening basally and with small inner process ( Fig. 151 View FIGURES 150 – 158. 150 – 153 ); tegmen with penis guide distinctly longer than paramere, in lateral view straight ( Fig. 152 View FIGURES 150 – 158. 150 – 153 ); penis guide in ventral view subparallel, apex rounded ( Fig. 153 View FIGURES 150 – 158. 150 – 153 ); parameres thin and straight, with dense long setae.

Female genitalia: Unknown.

Holotype: 1male, China, Guizhou: Chenguan District, Wangmo , [25°9.99′N, 106°5.28′E], ca 860m, 19.vi.1986, Ren SX leg ( SCAU) GoogleMaps . Paratype: 1male, same data as holotype GoogleMaps .

Distribution. China: Guizhou.

Etymology. The name of this new species is formed from the Latin noun flammula , referring to elytra with flame-shaped maculae.
