description: Glaucocharis brevis sp. n.
(Figs. 2, 11, 20)
Type material. Holotype 3, Dashahe, Daozhen (28°53ʹN, 107°36ʹE), Guizhou Province, 1450 m, 23.v.2004, leg. Shulian Hao, genitalia slide No. LWC07235. Paratypes: 2 ƤƤ, same data as holotype except 600–1450 m, 23, 28.v.2004; 7 3, 10 ƤƤ, Kuankuoshui (28°15ʹN, 107°01ʹE), Suiyang, Guizhou Province, 840–1500 m, 3- 9.vi.2010, leg. Linlin Yang (NKUM).
Diagnosis. This species is similar to G. r a m o n a (Bleszynski, 1965) in appearance, but can be separated by the conspicuously different male genitalia. In G. brevis sp. n., the gnathos is about five times as long as uncus and bears two apical spines, the valva is truncate apically, and the juxta bears two lateral clusters of long and outcurved spines. In G. r a m o n a, the gnathos is nearly as long as uncus and bears a single prong, the valva is pointed apically, and the juxta lacks the clusters of long spines, but bears an accessory structure that broadens from narrow base to slightly concave posterior margin. This species also resembles G. flavifasciaria sp. n. in appearance, but can be distinguished by the gnathos much longer than uncus, the costa without protuberance, and the U-shaped juxta; while in G. flavifasciaria sp. n., the gnathos is a bit shorter than uncus, the costa bears a large protuberance before middle, and the juxta is V-shaped.
Description. Adult (Fig. 2). Forewing length 5.5–7.0 mm. Frons and vertex pale yellow. Labial palpus pale brown on outer side except distal one third of second segment pale yellow, pale yellow on inner side. Maxillary palpus pale brown, white basally, yellowish white distally. Antenna with dorsal surface pale brown and yellowish white alternately, ventral surface pale yellow ciliated white. Patagium pale brown to blackish brown, mixed with pale yellow. Tegula pale yellow, blackish brown on outer side. Thorax blackish brown. Forewing densely covered with pale brown scales; antemedian line blackish brown, straight or gently outcurved; broad pale yellow fascia along outside of antemedian line, with width about one seventh length of forewing; reniform stigma black, small and rounded; postmedian line blackish brown, inconspicuous medially, angled outwards at anterior one third and inwards at posterior one fourth; apex pale yellow, with white apical stripe; termen orange yellow, with three black marginal spots; fringe pale brown, white basally and medially on apex. Hindwing white in male, pale brown in female; fringe white except pale brown subbasally. Male abdomen white and pale brown alternately, female abdomen pale brown. Legs yellowish white, femur and tibia of foreleg pale brown on outer side.
Male genitalia (Fig. 11). Uncus broad and short, rounded apically. Gnathos slender, about five times as long as uncus, bearing two apical spines. Valva broad basally, narrowed to truncate apex. Costa well-sclerotized, concave at about two thirds. Juxta U-shaped, with two clusters of outcurved spines posterolaterally. Phallus about three fourths length of valva, curved medially; distal one third with some tiny spinelike cornuti.
Female genitalia (Fig. 20). Papilla analis ovate, about half length of apophysis posterioris. Tergite eight about two fifths length of apophysis anterioris. Tergite seven sclerotized and spinous posteriorly. Ostium bursae surrounded by dense spinules. Ductus bursae long and thin. Ductus seminalis arising from anterior two fifths of ductus bursae. Corpus bursae ovate; signa double and rounded, one placed at near posterior margin of corpus bursae, another placed at posterior one third of corpus bursae.
Distribution. China (Guizhou).
Etymology. The specific name is derived from the Latin word brevi s = short, in reference to the distinctively short uncus in the male genitalia.
