Type material.

Holotype: ♂ ( MHBU), China, Chongqing, Wuxi, Shuangyang, Yingtiaoling Natural Reserve , Linkouzi , 1224 m, 22. VI. 2022, leg. L. Y. Wang.

Differential diagnosis.

The new species can be separated from all other Ponyalis by the combination of the following characters: pronotum uniformly black, elytral red (Fig. 10 B ); male antennomere I flattened dorsally, III and IV long-triangular, lamellae of V – X nearly parallel-sided along the whole length, lamella of VI longer, 1.8 × longer than joint itself (Fig. 10 B ); primary costae much stouter than the secondary ones, cells most squared (Fig. 10 B ); phallus projected distad at apical margin and arched at apex in dorsal and ventral views (Fig. 9 J, K ).

It is most close to P. quadricollis in general appearance, but can be distinguished from the latter by the following characters: primary costae strongly stouter than secondary ones (Fig. 10 B ), while barely stouter in P. quadricollis (Fig. 10 A ); phallus barely widened at basal part in dorsal and ventral views (Fig. 9 J, K ), while moderately widened at middle part in P. quadricollis (Fig. 9 G, H ); phallus with distance between the latero-apical thorns barely greater than maximal width of trunk (Fig. 9 J, K ), while barely smaller in P. quadricollis (Fig. 9 G, H ).

Description.

Male (Fig. 10 B ). Body slender, black to dark brown, pronotum dark-brown, elytra red.

Head dorsally flat, antennae reaching apical 1 / 5 length of elytra when inclined, antennomere I flattened dorsally, III and IV long-triangular, 1.4–1.5 × as long as wide, lamellae of V – X nearly parallel-sided along the whole length, 1.5–2.8 × longer than the corresponding antennomere itself, XI fusiform and 5.5 × as long as wide.

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

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

Aedeagus: phallus stout, 3.0 × as long as wide, hardly widened at basal part, moderately projected distad at apical margin and arched at apex in dorsal and ventral views, with acute latero-apical angels, between which the distance barely greater than maximal width of trunk (Fig. 9 J, K ), almost even in width and nearly straight, truncate at ventro-apical 1 / 4 in lateral view (Fig. 9 L ).

Female. Unknown.

Distribution

(Fig. 1 ). China (Chongqing).

Etymology.

The name of the species is derived from the Latin minus (imitator), referring to its similarity to P. quadricollis .
