Paratype : China : 1 ♂ ( CAU ), Zhejiang , Xitianmushan, V . 1960 , leg. J. K. Yang. Differential diagnosis. This species can be separated from all other Ponyalis by the combination of the following characters: pronotum black, with red margins, elytra red (Fig. 8 C ); male antennomere I nearly globular, III long-triangular, lamellae of IV – X abruptly extended laterally and nearly parallel-sided along the whole length, lamella of IV long and 2 × longer than joint itself (Fig. 8 C ); elytral primary costae much stouter than the secondary ones in whole length, cells most squared (Fig. 8 C ); phallus widened at apical part and arcuate at lateral margins, nearly straight at apical margin in dorsal and ventral views (Fig. 9 D, E ). The new species is similar to P. fukiensis in the body coloration and extremely long lamellae of antennomeres IV – X, but can be distinguished from the latter by the following characters: male antennomere III with outer apical angle barely protruding laterally (Fig. 8 C ), while strongly protruding laterally in P. fukiensis (Fig. 2 C ); phallus nearly straight at apical margin (Fig. 9 D, E ), while moderately projected distad in P. fukiensis (Fig. 3 D, E ); phallus with distance between the latero-apical thorns barely greater than maximal width of trunk (Fig. 9 D, E ), while barely smaller in P. fukiensis (Fig. 3 D, E ). Description. Male (Fig. 8 C ). Body slender, black to dark brown, pronotum red, with a black patch in the middle of disc, elytra red. Head dorsally flat, antennae reaching apical 1 / 5 length of elytra when inclined, antennomere I nearly globular, III long-triangular, 1.6 × as long as wide, with outer apical angle barely protruding laterally, lamellae of IV – X abruptly extended laterally and nearly parallel-sided along the whole length, 2.9–7.0 × longer than the corresponding antennomere itself, XI nearly parallel-sided and 11.0 × as long as wide. Pronotum nearly trapezoidal, flat, and barely wider than long, with rounded anterior angles and acute posterior angles, anterior margin arched, lateral margins nearly straight and posterior margin bisinuate. Scutellum barely narrowed posteriorly and obviously emarginate at apex. Elytra barely widened posteriorly, primary costae stouter than secondary ones, and primary costae II and III stouter than others in whole length of elytra, most cells squared to rectangular. Aedeagus: phallus stout, 2.8 × as long as wide, moderately widened at apical part and arcuate at lateral margins, nearly straight at apical margin in dorsal and ventral views, with sharp latero-apical thorns, between which the distance barely smaller than maximal width of trunk (Fig. 9 D, E ), almost even in width and weakly bent dorsally, truncate at ventro-apical 1 / 5 in lateral view (Fig. 9 F ). Female. Unknown. Distribution (Fig. 1 ). China ( Anhui , Zhejiang ). Etymology. The specific name is derived from the Latin truncatus (cut off), referring to its phallus nearly straight at apical margin.
