Forewings black with numerous, small dark, irregular yellow markings in cells; mesonotum black with dark yellow spots; pronotum black, bullae dark yellow, crown yellow with black markings in each side of middle, eyes dark brown; face yellow, short brown transverse stripes on inner lateral margins, clypellus yellow with tinge of brown medially; head narrower than pronotum, anterior margin obtusely rounded; crown short, broad, slightly narrower than width of eyes; pronotum large, nearly twice as long medially as crown; mesonotum large, nearly half again as long medially as pronotum; clypeus long, narrow, lateral margins broadly convex; clypellus short, narrow, lateral margins parallel.

Male genitalia. Male pygofer in lateral view broadly triangular, caudodorsal process short, broad basally, narrow, curved distally, caudoventral process long, broad in apical half, serrate on ventral margin in apical half ( Fig. 353 ), in dorsal view caudodorsal processes narrowed apically, hooked apically ( Fig. 354 ); aedeagus moderately long, shaft inflated in basal half, slightly inflated in distal 1/ 5 in dorsal view, in lateral view apex curved laterally, toothed on dorsal margin in apical region ( Fig. 355, 356 ); style small, apophysis short, digitate ( Fig. 357, 358 ); dorsal connective short, narrow ( Fig. 355 ); connective moderately large, anterior arms curved anteriorly, medial ridge complete, stem broad, sub ovate ( Fig. 359 ); subgenital plate long, broad, sparsely setose apically ( Fig. 360 ).

Material examined. Holotype male. THAILAND: Phetchabun, Thung Salaeng, Luang, Pine forest , Gang Wang Nam Yen , 16 o 36.284’N 10 o 53.128' E., 749 m. / pan trap, 19-20.vi.2007, Pongpitak and Sathit, leg. T2055 ( QSBG).

Etymology. The name of the species is descriptive for the evenly serrated ventral margin of the caudoventral pygofer process.

Remarks. This species can be distinguished by the combination of the following features: Aedeagus inflated in basal half in dorsal view, pygofer caudodorsal process narrow apically and curved laterally in lateral and dorsal views and the broad subgenital plate.
