Figs 1, 11 G – I, 12 C, D

Type material.

Holotype: ♂ (IZAS), China, Hainan, Jianfeng, 21. V. 1980, leg. F. J. Pu . Paratype: 1 ♀ (IZAS), same data as the holotype .

Differential diagnosis.

This new species can be readily identified from all other Ponyalis by the combination of the following characters: pronotum uniformly black, elytra red (Fig. 12 C, D); male antennomere I flattened dorsally, III and IV long-triangular, lamella of VI longer, 1.8 × longer than joint itself (Fig. 12 C); elytral primary costae much stouter than the secondary ones, cells transverse (Fig. 12 C, D); phallus widened near middle and sinuate at lateral margins, projected distad and narrowly rounded at apical margin in dorsal and ventral views (Fig. 11 G, H).

It looks like P. klapperichi in the general appearance, but can be distinguished from the latter by the following characters: male pronotum broad (0.7 × longer than wider) (Fig. 12 C), while slender in P. klapperichi (0.9–1.0 × longer than wider) (Fig. 6 A); lamella of antennomere VII 2.3 × longer than joint itself (Fig. 12 C), while 3.0 × in P. klapperichi (Fig. 6 A); phallus moderately projected distad at apical margin (Fig. 11 G, H), while nearly straight in P. klapperichi (Fig. 5 A, B).

Description.

Male (Fig. 12 C). Body stout, black, pronotum dark-brown, elytra cinnabar red.

Head dorsally flat, antennae reaching elytral mid-length when inclined, antennomere I barely flattened dorsally, III – IV long-triangular, 1.3–1.5 × as long as wide, lamellae of V – VII extended along whole length of corresponding stem and tapered laterally, 1.5–2.3 × longer than the corresponding antennomere itself.

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

Elytra barely widened posteriorly, primary costae stouter than secondary ones, primary costae II, III and IV stouter than others in whole length of elytra, most cells rectangular.

Aedeagus: phallus stout, 2.1 × as long as wide, abruptly widened at middle and sinuate 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 much smaller than maximal width of trunk (Fig. 11 G, H), almost even in width and weakly bent dorsally, truncate at ventro-apical 1 / 4 in lateral view (Fig. 11 I); internal sac membranous and expanded, densely covered with minute tubercles and short bristles on surface, abruptly thinned into a thorn-like apex (Fig. 11 G – I).

Female (Fig. 12 D). Similar to male, but body stouter.

Distribution

(Fig. 1). China (Hainan).

Etymology.

The name of the species is derived from the name of the type locality, Hainan Island, China.

Remarks.

The left pro- and meso-legs, left VIII – XI and right VI – XI antennomeres of the holotype, and both antennomeres II – XI, left proleg, and the right pro- and mesotarsomeres III – V of the paratype are missing.
