Redescription.

Male (Fig. 1). Body black, except mandibles dark brown, antennomeres I–II brown on ventral sides, pronotum yellow, with a large black marking extending from anterior to posterior margin, elytra green, with strongly metallic shine.

Head rounded, surface matt on frons, densely punctate on vertex, eyes slightly protruding, head width acrossing eyes distinctly narrower than pronotum; terminal maxillary palpomeres nearly long-triangular, widest at basal one-third; antennae filiform, extending to elytral middle length, antennomeres II about 3 times longer than wide, III slightly longer than II, IV–XI each with a narrow, smooth longitudinal to oval groove nearly in middle of outer margin.

Pronotum wider than long, widest at anterior one-third, anterior margin straight, lateral margins sinuate, posterior margin bisinuate and narrowly bordered, anterior angles rounded, posterior angles slightly protruding, disc slightly convex at postero-lateral parts, surface lustrous, slightly largely and sparsely punctate.

Elytra nearly parallel-sided, about 3 times longer than width at humeri, about 4 times of length of pronotum, dorsum finely punctate, lustrous at anterior one-third parts, roughly but shallowly rugoluse-lacunose on the rest.

Legs: all outer tarsal claws each with a triangular lobe at base, inner claws simple.

Aedeagus (Figs 5-7): ventral process of each paramere narrow, distinctly shorter than conjoint dorsal plate; conjoint dorsal plate with apical margin widely emarginated in middle, lateroapical angles obtusely dentated, each side with a large tooth near apical margin on inner surface; laterophyse adhered to median lobe, with apex bent towards middle, the portion around the bending corner with upper margin slightly protuberant and bent dorsally.

Female. Similar to male, but eyes smaller, terminal maxillary palpomeres shorter, nearly widest in middle, antennae shorter, extending to elytral one-third length, antennomeres IV–XI without any groove, pronotum wider, elytra with lateral margins slightly diverging posteriorly, abdominal sternite VIII (Fig. 8) largely emarginated in middle and slightly emarginated on both sides of posterior margin, the portion between middle and each lateral emarginations rounded at apex.

Body length: 9.0-11.0 mm; width: 2.0-2.5 mm.

Distribution.

China (Sichuan). Excluded from Yunnan province at the moment.

Remarks.

In the study, the type series of this species were discovered to be plural and consist of two species. Except the true Taiwanocantharis thibetanomima , which was located in Sichuan, China, the paratypes from Yunnan, China designated in the original publication belong to another unknown species described below, Taiwanocantharis wittmeri sp. n. Besides, the photos of aedeagus provided by Wittmer (1997b) is not of Taiwanocantharis thibetanomima but Taiwanocantharis wittmeri sp. n. So it is necessary to redescribe and illustrate this species here.
