Diagnosis.

The genitalia of this species are very similar to those of Nyctiophylax (Paranyctiophylax) nahum  (Malicky & Chantaramongkol, 1993) in the long basoventral process of each inferior appendage and in the long slender dorsal process of each preanal appendage. However, in the new species the dorsal process of each preanal appendage is long and stout, curved caudolaterad in dorsal view, but straight and much more slender in Nyctiophylax nahum  ; and the basoventral process of each inferior appendage forms a 45-degree angle with the main body of the appendage in lateral view in the new species, but an angle of about 90 degrees in Nyctiophylax nahum  . The shape of the mesoventral process of each preanal appendage is somewhat similar to that of Nyctiophylax (Paranyctiophylax) devanampriya  (Schmid, 1958), but in that species the basoventral process of each inferior appendage is much shorter than that of the new species, which is about 1/3rd as long as the main body of the appendage.

Description of adult male.

Head grayish brown with yellowish antennae, pronotum light gray, meso- and metanota brown dorsally, yellowish lateroventrally with concolorous thoracic legs, forewings light brown. Length of body with folded forewings: 4.3-5.5 mm (n=15).

Male genitalia. Tergum IX short, membranous, broadly rounded apically in dorsal view (Fig. 7C). Sternum IX relatively large, in lateral view (Fig. 7A) subtriangular, with short posterodorsal margins 1/3rd as long as ventral surface, anterolateral margins oblique and convex, especially subventrally, posterolateral margins nearly straight, vertical; in ventral view (Fig. 7B), posteromesal margin broadly and shallowly excised, anteromesal margin with short V-shaped excision. Tergum X fused laterally to tergum IX, represented as 2 small setose lateral lobes. Without obvious intermediate appendages. Preanal appendages slender, straight in lateral view (Fig. 7A), curved slightly caudad in dorsal view (Fig. 7C); each with long dorsal process curved caudolaterad, acute apically; its mesoventral process broad at basal 2/3rds, with acute apex hooked slightly ventrad and mesad beneath phallus. Inferior appendages each with acute posterior basoventral process half as long as main body of appendage; main body of appendage slender, setose, and acute apically. Phallus with phallobase sclerotized, broader apically, with pair of short sclerites dorsally, phallicata membranous, without internal spines.

Female and immature stages.

Unknown.

Distribution.

Oriental Biogeographic Region, China (An-hui, Jiang-xi).

Etymology.

Pungens, Latin adjective, „acute,“ referring to the acute, posterior basoventral process of each inferior appendage.
