Taharana gracilata , sp. nov.

( Plate 7D , Fig. 410-416 )

Description. Length. Male 7.00-7.40 mm., female unknown.

External morphology. Moderately large, slender species. General color black; forewings black with short, yellow stripes on veins, dark brown, irregularly shaped markings in cells; mesonotum black, without markings; pronotum black, bullae yellow; crown light to dark brown, without markings; eyes light to dark brown; face light brown, without markings; head narrower than pronotum, anterior margin rounded; crown moderately long, narrower than width of eyes, slightly produced anteriorly, lateral margins convergent basally; eyes large, semiglobular; pronotum moderately large, about as long medially as crown, surface bullated; mesonotum large, longer medially than pronotum; clypeus long, narrow, lateral margins broadly convex; clypellus short, narrow, apex flared.

Male genitalia. Pygofer in lateral view narrow, long, glabrous, caudodorsal process very narrow, subapical spine in dorsal view, caudoventral process long, slightly sinuate, broad medially, tapered sharply apically, short row of small teeth on ventral margin medially ( Fig. 410 ), in dorsal view caudodorsal processes caliperate with small subapical spine on inner lateral margin ( Fig. 411 ); aedeagus long, tubular, shaft slightly broad in basal 1/3, tubular in distal 2/ 3 in lateral view, patch of small teeth in dorsoapical margin, gonopore sub-medial ( Fig. 412, 413 ); style very small, base large with short, digitate apophysis ( Fig. 414 ); dorsal connective long, narrow ( Fig. 412 ); connective small, anterior arms very narrow, medial ridge complete, stem digitate ( Fig. 415 ); subgenital plate moderately long, somewhat broad ( Fig. 416 ).

Material examined. Holotype male. THAILAND: Nakhon Si Thammarat, Namtok Yong NP, Behind / Campground Lavatory , 8 o 10.44’N 99 o 44.508’E, 80 m., / Pan trap, 30-31.vii.2008, U. Prai. K., leg., T3085 ( QSBG) . Paratypes. 4 males, same data as holotype, T 3080, T 3075, T 3075, T 3979 ( QSBG, ULKY, MLBM).

Etymology. The species name is descriptive for the slender pygofer processes and connective.

Remarks. This species is similar to T. forcipia in features of the pygofer caudoventral process and can be distinguished by the pygofer with the subapical spine on a very narrow caudodorsal process and broader arms of the connective.
