Material examined.

3♂1♀, Myanmar, near 1.5 km from the roadside between Kanpetlet and Nat Ma Taung National Park; 21°13.058'N, 93°59.033'E; elevation ca 2420 m; 1.V.2017; Wu J. and Chen Z. leg. (IZCAS AR-25151-25152-25153-25154).

Diagnosis.

Males of this species can be recognized by the circular, scale-like structure on the distal part of the bulb (white arrows in Fig. 2E, F) and the cymbium, which has two or three stout, dark setae with large bases (black arrows in Fig. 2G). Females are distinguished by having a darkened band (db) on the posterior margin of the epigastric furrow (Figs 3G, 15A).
