Promalactis flavescens Wang, Zheng & Li, 1997: 202; Wang 2006: 32. Type locality: China (Shaanxi).

Material examined.

China,Sichuan Province: 4 ♂, 2 ♀, Mt. Qingcheng, 19−24.V.1979; 1 ♂, 1 ♀, Wanniansi, Mt. Emei, 14.VI.1979, genitalia slide Nos. DZH12042 ♂, DZH12014 ♀ (IOZ).

Diagnosis.

Adult with wingspan 12.5−14.0 mm. This species is similar to Promalactis bitaenia Park & Park, 1998, but can be separated by the forewing with a dark brown fascia (Fig. 16); the sacculus with a bundle of strong setae on the dorsal margin distally, the aedeagus about twice length of the valva and with a small subapical tooth in the male genitalia ( Wang 2006, fig. 40); the lamella postvaginalis with the dorsal part nearly quadrangular and the ventral part trapezoidal in the female genitalia (Fig. 39). In Promalactis bitaenia , the forewing has two dark brown fasciae; the sacculus has spines and small teeth on dorsal margin distally, and the aedeagus is slightly longer than the valva and lacks the subapical tooth; and the lamella postvaginalis is irregularly rounded.

Female genitalia (Fig. 39). Apophysis anterioris about 1/2 length of apophysis posterioris. Eighth tergum with sparse long setae on posterior margin. Lamella postvaginalis heavily sclerotized, dorsal part elongate, nearly quadrangular, rounded on posterior margin, ventral part short, about 3/5 length of dorsal part, trapezoidal; lamella antevaginalis large, anterior 3/5 broad and slightly convex laterally, narrowed near anterior margin, anterior margin straight, triangularly protruded backward at anterior 3/5 laterally. Antrum elongate, tubular, posterior 1/3 broader. Ductus bursae weakly sclerotized except basal small portion heavily sclerotized, membranous near corpus bursae, with two plates near middle: one plate hand shaped, protruded, with three strong, curved spines on anterior edge; the other plate subtriangular, with very short spines on anterior edge. Corpus bursae small, rounded and membranous; signum absent.

Distribution.

China (Shaanxi, Sichuan).
