Diagnosis.
This species can be separated from other known species of the genus by the spinous, narrowly tongue-shaped ventral plate of gnathos; by the reniform valva, in which the sacculus is elongately triangular with a short spine-shaped apex; and by the short phallus, which bears two small sclerotized plates at distal 1/5.
Description.
Adult (
Fig. 7
): Wing expanse 13.0-14.0 mm. Head white, covered with sparse long hairs. Labial palpus white, tinged with yellow on outside of second segment. Antenna with scape white, flagellum pale yellow. Thorax, tegula and forewing white. Forewing mixed with yellowish brown scales, with a triangular yellowish brown blotch on tornus and a round brown spot on distal 1/3 of fold; costal margin with basal 1/ 6 black, distal 2/5 yellowish brown; termen oblique; cilia white except distal 1/4 dark yellowish brown. Hindwing and cilia greyish white; outer margin pale yellow. Legs white, except hind tibia black at apex and tarsus pale yellow.

Male genitalia (
Fig. 14
): Socius slender, slightly widened medially, strongly sclerotized and hooked distally. Tuba analis membranous. Gnathos with ventral plate narrowly tongue shaped, spinous. Valva broad and short, reniform, with fine hairs in distal 2/3, nearly same width from base to near apex; apex rounded; inner process of proximodorsal part horn shaped; costa concave at 3/5. Sacculus longer than half length of valva, elongately triangular, with sclerotized, short spine-shaped apex. Saccus with posterior 1/3 broad U-shaped, anterior 2/3 slightly narrow and nearly parallel sided, apex rounded. Phallus short and straight, as long as saccus, more or less twisted, with a long dentation extending from about 1/3 obliquely to near apex; two small sclerotized plates at distal 1/5. Eighth sternite very developed (
Fig. 15
).
Female genitalia (
Fig. 16
): Papillae analis large and broad, somewhat rectangular, blunt on posterior margin. Apophyses anteriores short, about half length of apophyses posteriores. Lamella postvaginalis large, concave at middle and with short spines on posterior margin. Antrum broad, weakly sclerotized, protruding posterolaterally. Ductus bursae sclerotized, not clearly differentiated from corpus bursae. Corpus bursae irregularly long ovate; signum small, with teeth.
