Ankylopteryx (A.) delicatula : Banks 1937: 280 (original: Ankylopteryx ; type locality: Ryukyu (Japan, Okinawa); syntypes in MCZ); Kuwayama 1964: 42 ( Ankylopteryx ); Brooks and Barnard 1990: 265 ( Ankylopteryx (Ankylopteryx) ); Tsukaguchi 1995: 123 (key to Japanese species), 126, fig. 100 ( Ankylopteryx ).

Material examined.

China: 1 ex, Yunnan, Jinghong, Sanchahe, 620 m, 1981.IV.12, Yang Chikun (CAU); 1 ♀, Yunnan, Yingjiang, Tongbiguan, Jinzhuzhai, 2012.V.2, Liang Feiyang (CAU); 1 ♂, Hong Kong, 2015.V, Liang Minxuan (CLMX).

Diagnosis.

Frons with two brownish small spots between antennae, two brownish stripes below toruli; frontal markings more or less curved posteriorly and contiguous with clypeal markings anteriorly; gena with a long brownish stripe. Protibia and mesotibia with median markings. Both wings distinctly marked with brownish vittae along posterior margins near base and medial fork to apex of distal cubital cell (dcc). Abdomen with brownish markings on terga 2-8.

Supplemental description.

Female: Sternum 8 distinctly convex at median part of posterior margin, with setae apically. Subgenitale stubby, bilobed apically; spermatheca round, as wide as long; spermaduct coiled, about three times as long as spermatheca.

Distribution.

China (Yunnan, Hong Kong); Japan (Okinawa).

Remarks.

The frontal spots between antennae and vittae on both wings in our examined specimens from Yunnan are same with that in the type of A. delicatula , as originally described. Accordingly, we identified the above two specimens from Yunnan to be A. delicatula , which is newly recorded from China.
