Description.

Male (Fig. 2). 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 mixed green and bronze, 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 an gles rounded, posterior angles nearly rectangular, not protruding, disc slightly convex at postero-lateral parts, surface lustrous, finely and sparsely punctate.

Elytra nearly parallel-sided, about 3 times longer than width at humeri, about 3.5 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 (Fig. 9-11): ventral process of each paramere narrow, nearly as long as conjoint dorsal plate; conjoint dorsal plate with apical margin triangularly emarginated in middle, lateroapical angles acutely dentated, each side with a small tooth near middle of 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, all tarsal claws simple, abdominal sternite VIII (Fig. 12) largely emarginated in middle and slightly emarginated on both sides of posterior margin, the portion between middle and each lateral emarginations tapered at apex.

Body length: 8.0-11.0 mm; width: 2.0-2.5 mm.

Diagnosis.

This species is similar to Taiwanocantharis thibetanomima , but can be distinguished from the latter by the following characters: all tarsal claws simple in female; aedeagus: ventral process of each paramere nearly as long as conjoint dorsal plate, conjoint dorsal plate with lateroapical angels acutely dentated, each side with a small tooth near middle of apical margin on inner surface; abdominal sternite VIII of female with the portions between middle and lateral emarginations tapered at apex.

Distribution.

China (Yunnan).

Etymology.

This species is named after the late distinguished taxonomist Dr. Walter Wittmer.

Remarks.

This new species was described based on a part of the paratypes, which are located in Yunnan, China, of Taiwanocantharis thibetanomima . What’s noted, two paratypes provided with the information as "Yulongshan Mts., Baishui, 2900-3500m, 27°08'N, 100°14'E, 7.-12.VII.1990, 22. –24.VI.1993”, according to the original publication by Wittmer (1997), can not found in the collection of NHMB. But four not three paratypes labeled as "Jizushan Mts., 2500-3100m, 25°58'N, 100°21'E, 30.V. –3.VI.1993” were found in NHMB, all of them were designated as the paratypes of Taiwanocantharis wittmeri sp. n.
