Type material.

Holotype: ♂ ( MHBU), China, Sichuan, Emeishan, Baoguoshi , 902 m, 29. V. 2010, leg. Q. Yuan & S. Xian.

Differential diagnosis.

The new species can be differentiated from the remaining Ponyalis species by the combination of the following characters: pronotum black, with red margins, elytra red (Fig. 10 C ); male antennomere I nearly globular, III long-triangular, lamellae of IV – X nearly parallel-sided along the whole length, lamella of IX 2.5 × as long as joint itself (Fig. 10 C ); elytral primary costae much stouter than the secondary ones, cells most squared (Fig. 10 C ); phallus widened at middle part, moderately projected distad at apical margin and narrowly rounded at apex in dorsal and ventral views (Fig. 11 A, B ).

It seems similar to P. sichuanensis ( Bocak, 1999) on basis of the general appearance, but can be easily distinguished from the latter by the following characters: lamellae of male antennomere IX 2.0 × as long as joint itself (Fig. 10 C ), while 1.5 × in P. sichuanensis ; pronotum with a black patch extending to posterior margin (Fig. 10 C ), while never reaching in P. sichuanensis ; phallus arched at apical margin (Fig. 11 A, B ), while nearly straight in P. sichuanensis ( Bocak 1999: fig. 73).

Description.

Male (Fig. 10 C ). Body slender, black to dark brown, pronotum pale brown, with a black patch in middle of disc, which extending to posterior margin, elytra red, tibiae paler at bases.

Head dorsally flat, antennae reaching apical 1 / 5 length of elytra when inclined, antennomere I nearly globular, III long-triangular, 1.3 × as long as wide, lamellae of IV – X nearly parallel-sided along the whole length, 2.0–3.6 × longer than the corresponding antennomere itself, XI parallel-sided and 6.5 × as long as wide.

Pronotum nearly trapezoidal, flat, and barely wider than long, with rounded anterior angles and rectangular posterior angles, anterior margin barely arched, lateral margins nearly straight and posterior margin nearly straight. Scutellum barely narrowed posteriorly and obviously emarginate at apex.

Elytra parallel-sided, primary costae stouter than secondary ones, and primary costae II and IV stouter than others in whole length of elytra, most cells irregular.

Aedeagus: phallus stout, 3.1 × as long as wide, moderately widened at middle part and arcuate at lateral margins, moderately projected distad at apical margin and narrowly rounded at apex in dorsal and ventral views, with acute latero-apical angels, between which the distance barely smaller than maximal width of trunk (Fig. 11 A, B ), almost even in width and weakly bent dorsally, truncate at ventro-apical 1 / 5 in lateral view (Fig. 11 C ).

Female. Unknown.

Distribution

(Fig. 1 ). China (Sichuan).

Etymology.

The specific name is derived from the Latin longus (long) and cornus (horn), referring to its long antennae.
