Taharana oblongiserrata , sp. nov.

( Plate 7E , Fig. 417-423 )

Description. Length. Male 7.20-7.60 mm., female unknown.

External Morphology. Moderately large, slender species. General color dark brown to black; forewings dark brown to black, veins marked with short, yellow stripes, cells with numerous, light brown, irregular markings; mesonotum black with small dark yellow markings; pronotum black, bullae dark yellow; crown light yellow to dark brown; eyes translucent to dark brown; entire face light to dark brown; clypeus bordered with narrow black line; head narrower than pronotum, anterior margin broadly rounded; crown short, narrower than width of eyes, lateral margins convergent basally; clypeus long, narrow, lateral margins broadly convex; clypellus short, about 1/3 as long as clypeus, narrow, slightly inflated longitudinally along middle, apex flared.

Male genitalia. Pygofer in lateral view sub-triangulate, glabrous, with long narrow caudodorsal process, narrow in dorsal view, caudoventral process long, apical half expanded, serrate along ventral margin, sometimes expanded in apical 1/3 ( Fig. 417 ), in dorsal view caudodorsal processes broadly curved, apex obliquely truncate ( Fig. 418 ); aedeagus long, tubular, shaft inflated in basal 1/3, patch of fine teeth on dorsoapical margin, gonopore distad of middle ( Fig. 419, 420 ); style small, base large, apophysis short, digitate ( Fig. 421 ); dorsal connective moderately long, narrow ( Fig. 419 ); connective broad, anterior arms narrow, medial ridge complete, stem ovate ( Fig. 422 ); subgenital plate long, broad, glabrous ( Fig. 423 ).

Material examined. Holotype male. THAILAND: Chaiyaphum, Tat Tome NP., Lam Poi Ta, dry evergreen forest / head water, 15 o 58.486’N 102 o 02.239’E., 270 m., Malaise trap, 26.viii.-5.ix.2006 / Tawir Jaruphan and Orawan Budsawong, leg. T555 ( QSBG) . Additional material examined: 21 males, same data as holotype except several subspecific localities, coordinates and T numbers ( QSBG, ULKY, MLBM). Etymology. The species name is descriptive for the configuration of the pygofer caudoventral process.

Remarks. From T. minutura to which it is most similar in configuration of the pygofer caudoventral process, T. oblongiserrata can be separated by longer, narrower caudodorsal pygofer process in lateral and dorsal views, broader anterior arms of the connective and by the rounded apex and fewer, smaller teeth on the ventral margin of the pygofer caudoventral process.
