Fissocantharis laticornis sp. nov.

Figs. 7–8 , 12–14

Description. Male ( Fig. 7 ). Body black. Pronotum and elytra red, pronotum with a darkened median longitudinal stripe. Head, pronotum and elytra covered with reddish brown pubescence, ventral body with white pubescence, glabrous in middle of metasternum.

Head subquadrate, evenly narrowed behind eyes, surface densely and finely punctate, with a distinct middle longitudinal line, which distinctly depressed on vertex; eyes slightly protruding, breadth across eyes wider than anterior margin of pronotum; last maxillary palpomeres widest in middle, rounded at apex; antennae extending to apical one-third of elytra, antennomeres II as long as wide at apices, III – X serrate, each slightly flatted and obliquely widened apically, nearly long-triangular, of which VI widest at apex, VI – VIII each with a narrow longitudinal groove in middle of outer margin, XI longer than X, subparallel-sided and pointed at apex.

Pronotum subquadrate, almost as long as wide, widest near posterior margin, anterior margin arcuate, lateral margins diverging posteriorly, posterior margins nearly straight, anterior angles widely rounded, posterior angles nearly rectangular, disc distinctly convex on posterolateral parts, with a distinct median longitudinal groove.

Elytra about 3.5 times longer than pronotum, 3.5 times longer than wide at humeri, humeral width distinctly wider than posterior margin of pronotum, outer margins slightly converging posteriorly, disc surface densely and finely punctate, with 3 distinct longitudinal costae.

Legs: all claws bifid.

Aedeagus ( Figs. 12–14 ): ventral process of each paramere wide, strongly narrowed apically, rounded at apex, conjoint dorsal plate of parameres parallel-sided, slightly shorter than ventral process of each paramere, with a rounded emargination in middle of apical margin.

Female ( Fig. 8 ). Body wider, eyes less protruding, antenna shorter, extending to the middle of elytra, antennomeres VI – VIII without longitudinal narrow grooves, elytra with outer margins subparallel to each other.

Body length: 9.0 – 11.0 mm; width: 2.0 – 3.0 mm.

Type material. Holotype 3, Taiwan, Nantou Hsien, Mt. Howangshan , 17.III.1991, leg. T. Shinohara ( KURA). Paratypes: 1♀, same data as holotype ( KURA); 1♀, Taiwan, Taoyuan Hsien, Daguanshan, 4.IV.1991, leg. Y. Okushima ( KURA); 13, Taiwan, Nantou Hsien, Sungkang, 28.IV.1996, leg. C. Lou ( KURA) .

Distribution. Taiwan.

Diagnosis. This new species is easily distinguished from all other Taiwanese species of Fissocantharis by its body coloration and pubescence. It is related to several species distributed in southern China and adjacent areas, but distinguishable by the following key.

Etymology. The specific name is derived from Latin word “ latus ”(wide) and “ cornu ”(horn), referring to its antennomeres III – X widened apically.
