Taharana protriangulata , sp. nov.

( Plate 6H , Fig. 375-381 )

Description. Length. Male 7.60 mm., female unknown.

External morphology. Moderate size, robust species, General color black. Forewings black, veins with short yellow stripes, cells with brown, irregular shaped markings; mesonotum black with yellow spots; pronotum black, bullae yellow; crown light yellow, marked with black spots; eyes light brown; face yellow, clypeus with orange longitudinal band on inner lateral margin; head slightly narrower than pronotum, anterior margin broadly rounded; crown short, about as wide as width of eyes, slightly produced anteriorly, lateral margins convergent basally; pronotum moderately large, slightly longer medially than crown; mesonotum large, nearly twice as long medially as pronotum; clypeus long, broad, lateral margins broadly convex; clypellus short, narrow, apex flared.

Male genitalia. Pygofer in lateral view narrowly triangular, glabrous, caudodorsal process short, tapered apically, caudoventral process long, apical half serrate on ventral margin ( Fig. 375 ), in dorsal view, caudodorsal processes slightly bowed, apex sub triangulate ( Fig. 376 ); aedeagus long, tubular, shaft inflated in basal ¼, patch of small teeth on dorsoapical margin, gonopore near middle ( Fig. 377, 378 ); style small, very short, digitate apophysis ( Fig. 379 ); dorsal connective moderately long, narrow ( Fig. 377 ); connective small, anterior arms slightly curved, medial ridge complete, stem small, digitate ( Fig. 380 ); subgenital plate long, broad, glabrous ( Fig. 381 ).

Material examined. Holotype male. THAILAND: Sakon Nakhon, Phu Phan NP., Behind office / 17 o 03.488’N 103 o 58.497’E., Malaise trap, 27.vii-2.viii.2006. / Sailong, Tongboonch, leg. T208 ( QSBG).

Etymology. The species name is descriptive for the triangulate apex of the pygofer in lateral view and caudodorsal apex in dorsal view.

Remarks. The species is most similar to T. incisura in configuration of the caudoventral pygofer process and can be distinguished by the following combination of characters: apex of caudodorsal processes triangulate, (digitate in T. incisura ), shaft of aedeagus inflated in basal ¼, (inflated in basal half in T. incisura ), shorter, narrower subgenital plate and smaller style and connective than in T. incisura .
