( Figs. 1, 1 a, 1b, 5, 9, 9a, 9b, 9c, 13, 13a)

Lecithocera anglijuxta Wu, 1997 , Fauna Sinica Insecta 7: 126, 246. TL: Yunnan, China.

Remarks. The species was described from a single male ( China, Yunnan Province, 5 May 1956) ( Wu 1997). The wing venation and female genitalia are described below. The type is deposited in the Institute of Zoology, Beijing, China.

Diagnosis. This species can be distinguished from its congeners by the uniform yellowish-brown forewing color, the silvery-white antenna, and the unique shape of the uncus in the male genitalia.

Forewing ( Fig. 5 ). Wingspan 17.0–17.5 mm; R2 arising near upper corner of cell; R3 free from R4+5; R4 and R5 stalked beyond mid-length; R5 to termen; M1 far from R3 at base; M2 extending nearly parallel to M3; M3 free from stalk of CuA1+2; CuA1 and CuA2 stalked for ca. 1/4 length; cell closed. Hindwing with Rs and M1 stalked at 1/3; M2 well developed; M3 and CuA1 stalked near 1/2 length.

Male genitalia (Figs. 9, 9a, b). Described and illustrated by Wu (1997: plate 11, fig. 1).

Female genitalia (Figs. 13, 13a). Eighth sternum with round caudal margin. Apophyses anteriores slightly less than 1/2 length of apophyses posteriores, connected by heavily sclerotized band. Antrum membranous, not clearly distinct from ductus bursae. Ductus bursae narrow in posterior 1/4, then broadened and heavily wrinkled, with about 10 spinelike processes internally; the broadened part wider than corpus bursae and of approximately same length; ductus seminalis arising from posterior corner of the broadened part. Corpus bursae semi-ovate, membranous; signum plate elongate, ca. 1/3 length of corpus bursae, with dense conical spines on surface.
