General color dark brown to black; forewings with numerous yellow, small stripes on veins, cells reticulated; mesonotum light brown with dark markings; pronotum black with yellow bullae; crown tannish with few black spots; eyes dark brown to tannish; face tannish; clypeus with reddish brown longitudinal stripes on inner lateral margins; clypellus light brown; head much narrower than pronotum, anterior margin broadly rounded; crown short, narrow, narrower than width of eyes, slightly produced anteriorly, lateral margins convergent basally; eyes large, semiglobular; pronotum large, slightly longer medially than crown, surface bullated, mesonotum large, about half longer medially than pronotum; clypeus long, broad in posterior 1/3; clypellus narrow, slightly inflated longitudinally in middle, apex flared laterally.

Male genitalia. Pygofer in lateral view broadly triangulate, small digitate lobe distally, glabrous, without caudoventral process ( Fig. 83 ); aedeagus with shaft inflated in basal ¼ in dorsal and lateral views, shaft narrow, tubular in distal ¾, two short rows of short setae near middle of shaft in dorsal view, gonopore near middle ( Fig. 84, 85 ); style with long, narrow apophysis in distal 2/3 ( Fig. 86, 87 ); dorsal connective moderately long, narrow ( Fig. 84, 85 ); connective large, anterior arms narrow, tapered anteriorly, medial ridge incomplete, stem large, sub quadrate ( Fig. 88 ); subgenital plate long, with prominent apical spine, sparsely setose subapically on outer lateral margin ( Fig. 89 ).

NW/ Mae / Kamint entrance station 1, 14 o 38.123’ N 98 o 59.657’ E., Pan trap, / 18-19.ix.2008, Somboon and Daorueng, leg., T3455 ( MLBM) .

Etymology. The name of the species is descriptive for the 2 rows of brush-like subapical setae on the lateral margin of the aedeagus.

Remarks. The species is unique by the presence of a double row of aedeagal setae and can be separated by a combination of this feature, the inflated base of the aedeagus, the narrower connective, the very long apophysis of the style and the prominent apical spine of the subgenital plate.
