Material examined.

Japan: 1 ♂ (IZAS), Japan, Kyoto, 30. V. 1932, leg. S. Yie .

Differential diagnosis.

This species can be differentiated from all other Ponyalis by the combination of the following characters: pronotum uniformly black, elytra red (Fig. 10 A); male antennomere I flattened dorsally, III long-triangular, IV and V wide-triangular, lamellae of VI – X nearly parallel-sided along the whole length, lamella of VI longer, 1.8 × longer than joint itself (Fig. 10 A); elytral primary costae barely stouter than the secondary ones, cells transverse (Fig. 10 A); phallus widened at middle part, moderately projected distad at apical margin and arched at apex in dorsal and ventral views (Fig. 9 G, H).

Descriptive notes.

Male (Fig. 10 A). Antennae reaching apical 1 / 5 length of elytra when inclined, antennomere I flattened dorsally, III long-triangular, 1.2 × as long as wide, IV and V widely triangular, approximately as long as wide, with outer apical angels strongly protruding laterally, lamellae of VI – X nearly parallel-sided along the whole length, 2.0–3.4 × longer than the corresponding antennomere itself, XI nearly parallel-sided and 5.1 × as long as wide.

Aedeagus: phallus slender and 2.5 × as long as wide, moderately widened at middle part and arcuate at lateral margins, moderately projected distad at apical margin and arched at apex, with acute latero-apical angels, between which the distance barely smaller than maximal width of trunk (Fig. 9 G, H), weakly bent dorsally and tapered distad in lateral view (Fig. 9 I).

Distribution

(Fig. 1). Japan.

Remarks.

Bocak (1999) provided male antennae and aedeagus illustrations for this species, and we present the male habitus for the first time.
