Differential diagnosis.

This species can be easily separated from all other Ponyalis by the combination of the following characters: pronotum uniformly black, elytra bicolored, at least black at humeri (Fig. 7 A, B ); male antennomere I flattened dorsally, III long-triangular, lamellae of IV – X nearly parallel-sided along the whole length (Fig. 7 A ); elytral primary costae much stouter than the secondary ones in whole length, cells transverse (Fig. 7 A, B ); phallus moderately widened at middle part and arched at apex in dorsal and ventral views (Fig. 5 G, H ), weakly bent dorsally in lateral view (Fig. 5 I ).

Descriptive notes.

Male (Fig. 7 A ). Antennae reaching basal 3 / 5 length of elytra when inclined, antennomere I flattened dorsally, III long-triangular, 1.4 × as long as wide, lamellae of IV – X nearly parallel-sided along the whole length, 1.5–3.9 × longer than the corresponding antennomere itself, XI parallel-sided and 4.2 × as long as wide.

Aedeagus: phallus slender and 3.3 × as long as wide, moderately widened at middle part and arcuate at lateral margins, strongly projected distad at apical margin and arched at apex in dorsal and ventral views, with rectangular latero-apical angels, between which the distance barely smaller than maximal width of trunk (Fig. 5 G, H ), weakly bent dorsally and tapered distad in lateral view (Fig. 5 I ).

Female (Fig. 7 B ). Similar to male, but body stouter, antennae shorter and reaching elytral mid-length when inclined, antennomeres III – V all nearly triangular, lamellae of VI – X 1.1–1.5 × as long as its corresponding antennomere itself, XI fusiform and 2.6 × as long as wide.

Distribution

(Fig. 1 ). China (Henan, Shaanxi, Gansu, Hunan, Hubei, Sichuan).

Remarks.

Bocak (1999) and Kazantsev (2002) provided the illustration of the aedeagus for this species, and here we present the habitus of male and female for the first time.
