Cryptolechia olivaria sp. n.

( Fig. 16 )

Type material Holotype: ♂, CHINA: Mt. Tianmu (30°26'N, 119°34'E), Zhejiang Province, 1500 m, 18.viii.1999, coll. Houhun Li et al.

Diagnosis

This species is similar to C. acutiuscula in male genital characters but can be separated from the latter by the absence of spots along the costal margin of the forewing, the sharply pointed apex of the sacculus, and the aedeagus about 3/4 length of valva.

Description

Forewing length 14.5 mm. Head yellowish white. Labial palpus whitish yellow except for second segment black distolaterally; third segment slender and pointed apically, about 2/3 length of second. Antenna whitish yellow, flagellum scales brown and whitish yellow dorsally. Thorax, tegula, and forewing pale yellow, with light brown scales. Forewing lanceolate, with small brown dots at middle of cell, end of cell, and 3/5 of fold; a series of tiny brown dots from near apex along termen to tornus; cilia gray but yellow at base. Legs whitish yellow, with grayish­brown scales on outside of tibiae and tarsi, forming brown blotches on tarsi.

Male genitalia ( Fig. 16 ): Uncus long and slender, rodlike. Tegumen U­shaped. Valva slightly narrower in basal half, apex bluntly rounded; costa with sclerotized edge, basally extended, forming an olive­shaped, hairy process. Sacculus large, irregularly triangular, distal portion spine­shaped. Saccus triangular, distal portion abruptly narrowed, roundattenuate at apex. Aedeagus stout, about 3/4 length of valva, basal portion thin, distally with four sclerotized cornuti.

Female: Unknown.

Etymology The specific name is derived from the Latin olivarius (olivary), in reference to the costa of the valva bearing a hairy olive­shaped process basally.
