Pygofer side with dorsal appendage basal half inflated and distal half narrowed; ventrolateral setal group with 9 rigid setae, much smaller than macrosetae ( Fig. 9 ).

Holotype : ♂, THAILAND, Mae Hong Son, Namtok Mae Surin NP, Haad Saen / Huai Fai Kor reservoir, 19°20.857'N; 97°59.123'E, Malaise trap, 20-27.i.2008, coll. Kamkoon, A.
