Thubana dialeukos Park, 2003: 138.

Material examined.

1 ♂, China, Yunnan Province: Rare Botanical Garden, Ruili (24°00'N; 97°50'E), 1000 m, 6.VIII.2005, coll. Yingdang Ren, genitalia slide No. YLL08075.

Diagnosis.

This species is very close to Thubana leucosphena and hardly distinguishable from the latter by the superficial characters (Fig. 2) and the venation. However, it can be easily differentiated by the following characters of the male genitalia (Fig. 8): the valva broad at base, narrowed to before middle, gently raising obliquely upward in distal half, narrowed to blunt apex; the costa straight in basal 1/6, gently concave in distal 5/6; the juxta quadrate, with small, slender, almost straight posterolateral lobes; the aedeagus stout, shorter and broader than valva, with two dentate preapical lobes, and the cornuti consisting of a S-shaped fragment and a mass of short spines.

Distribution.

China (Yunnan), Thailand.

Notes.

This species is recorded for the first time in China.
