( Figs. 1 e, 2e, 3b, 4e)

Homaloxestis saitoi Park, 2004: 39 . Type Locality: Chiang Mai, Loei, Nakhon, Thailand.

Material examined. CHINA: 1 ♂, 3 ♀, Ruili Rare Arboretum, Ruili County (23º38′N, 97º59′E) Yunnan Province, 1000 m, 6, 7.viii.2005, coll. Yingdang Ren.

Diagnosis. Adult ( Fig. 1 e) with wingspan 15.0–16.0 mm. Seventh sternite ( Fig. 4 e) with lateral ribs moderately sclerotized, antero-median rod narrowed to bluntly rounded apex. This species can be separated from its congeners by the valva with the median part nearly parallel dorso-ventrally and triangularly protruded dorsodistally in the male genitalia ( Fig. 2 e). The female genitalia ( Fig. 3 b) differ from those of the known species of the genus by the ductus bursae medially inflated on one side and with many conical spinules internally; the inflated part is about twice as wide as the anterior part.

Distribution. China (Yunnan), Thailand.

Notes. This species is newly recorded for China.
