Material examined.

China: 1 ♂ (IZAS), Yunnan, Lijiang, 3100 m, 27. V. 1980, leg. L. Y. Wang; 1 ♂ (IZAS), Yunnan, Mancheng, 1700 m, 16. IV. 1980, leg. P. Gao.

Differential diagnosis.

This species can be differentiated from all other Ponyalis by the combination of the following characters: pronotum red, present with a large black patch, extending to anterior and posterior margins, elytra red (Fig. 6 C, D); male antennomere I flattened dorsally, III – IV long-triangular, lamellae of V – X extended along whole length of corresponding stem and tapered laterally (Fig. 6 C); elytra 5.5 × longer than pronotum and 1.2–1.3 × wider than posterior margin of pronotum, primary costae nearly as strong as the secondary ones, cells transverse (Fig. 6 C, D); phallus abruptly widened near middle part, moderately projected distad at apical margin and narrowly rounded at apex in dorsal and ventral views (Fig. 5 D, E).

Descriptive notes.

Male (Fig. 6 C, D). Antennae reaching apical 1 / 4 length of elytra when inclined, antennomere I flattened dorsally, III and IV long-triangular, 1.3–1.4 × as long as wide, lamellae of V – X extended along whole length of corresponding stem and tapered laterally, 1.2–2.2 × longer than the corresponding antennomere itself, XI fusiform and 5.0 × as long as wide.

Aedeagus: phallus stout, 2.3 × as long as wide, abruptly widened near middle part and obtusely angled 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. 5 D, E), almost even in width and weakly bent dorsally, truncate at ventro-apical 1 / 4 in lateral view (Fig. 5 F).

Distribution

(Fig. 1). China (Yunnan), Vietnam, Myanmar.

Remarks.

As noted by others (e. g., Bocak 1999), this species shows some variations in the coloration of pronotum, of which the black patch could be extending to anterior margin (Fig. 6 D) or not (Fig. 6 C).
