Style triangular apically, apical part curved dorsad ( Fig. 21f ). Aedeagal shaft slightly curved dorsad, pair of apical processes long, slightly expanded subapically; preatrial process short, not reaching gonopore, apical margin slightly concave in ventral view; gonopore central ( Figs. 21h, i ).

Measurement: Male 2.90mm.

Material examined: Holotype: ♂ [ QSBG], THAILAND: Kanchanaburi, Khuean Srinagarindra NP, Huai Mae Kamint / Tourist center, 14°38.123'N, 98°59.657'E, Malaise trap, 9–16.x.2008, coll. Somboon & Daorueng.
