Pisacha encaustica (Jacobi, 1916) comb. nov. & stat. rev.

Soaemis encaustica Jacobi, 1916: 311; Melichar, 1923: 168.

Pisacha naga Distant, 1906: Ishihara, 1965: 207; Wu and Yang, 1989: 166, fig. 3.

Notes. The species Pisacha encaustica (Jacobi, 1916) was firstly described according to one male specimen from Taiwan. Subsequently, it was mistakenly placed as synonym of P. naga by Ishihara (1965) and also misidentified as P. naga by Wu and Yang (1989). The species P. encaustica is clearly different from P. naga (Figs 31–34) by the tegmina without any mark, mesonotum without wide black stripe along lateral carina and frons with median carina present at basal fourth, in P. naga, tegmina with two black stripes, mesonotum with wide black stripe along transverse carina and lateral carina, median carina present at basal half. Conversely, it is very similar to P. kwangsiensis (Figs 35–37), but can be easily distinguished from the latter by 1) dorso-basal portion of phallobase with apico-ventral angle blunt in lateral view (Wu and Yang, 1989, Fig. 3 F), in P. kwangsiensis, dorso-basal portion of phallobase with apico-ventral angle sharp (Fig. 46); 2) dorso-lateral phallobase lobes with doral margin smooth, and lateral apex forming into a pair of bifurcate processes, the two branches have equal length, in P. kwangsiensis, dorsal margin of dorso-lateral phallobase lobes with a pair of small triangular processes at middle, the apical bifurcate processes with upper branch about half length of the under branch; 3) phallus with a pair of shallowly curved short processes, apex directed caudad (Wu & Yang, 1989, Fig. 3 G), in P. kwangsiensis, phallus with a pair of deeply curved hooks backward, apex directed dorsally (Fig. 46); 4) sternum VII with posterior margin slightly convex medianly (Wu & Yang, 1989, Fig. 3 H), in P. kwangsiensis, sternum VII with posterior margin slightly concave in middle (Fig. 53).
