Taharana abstrusa , sp. nov.

( Plate 5E , Fig. 289-295 )

Description. Length. Male 7.40-7.50 mm., female unknown.

External morphology. Moderate size, slender species. General color dark brown to black. Forewings with numerous brown irregular shaped markings in cells, veins with short, dark yellow stripes; mesonotum black with few dark yellow spots; pronotum black, bullae dark yellow; crown light brown to black; eyes grey to dark brown; face light to dark brown; head narrower than pronotum, anterior margin obtusely rounded, crown short, 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, nearly twice as long medially as pronotum; clypeus long, moderately broad, lateral margins broadly convex; clypellus short, about 1/3 as long as clypeus, narrow, apex flared.

Male genitalia. Pygofer in lateral view subtriangulate, glabrous, caudodorsal processes long, narrow with small subapical spur on dorsal margin, caudoventral processes long, narrow, sharply attenuated ( Fig. 289 ), in dorsal view, caudodorsal processes narrow, slightly curved mesally in apical 1/3, constricted subapically, caudoventral processes triangulate apically, serrate on inner lateral margin ( Fig. 290 ); aedeagus long, tubular, shaft slightly inflated in basal ¼, finely toothed in apical ¼ on dorsal surface, gonopore distad of middle ( Fig. 291, 292 ); style small, apophysis short, digitate ( Fig. 293 ); dorsal connective short, narrow ( Fig. 291 ); connective large, arms tapered, medial ridge complete, stem small, sub ovate ( Fig. 294 ); subgenital plate short, broad medially, glabrous ( Fig. 295 ).

Material examined. Holotype male. THAILAND: Phetchabun, Thung Salaeng Luang NP / Pine forest, Gang Wang Yeb 16 o 36.284’N 100 o 53.128’E, 749 m. / Malaise trap, 22-29.vi.2007, Pongpitak and Sathit, leg. T2063 ( QSBG); 3 males, same data as holotype except Nam Nao NP, Forest protection unit- Huay Praland / cave, 16 o 44.963’N. 101 o 27.833’E., 711 m., Pan traps, 19- / 20.i.2007, Noopean Hongyothi and Leng Janteab, leg. T1616 , T1617 , T1618 ( QSBG, ULKY, MLBM).

Etymology. The name of the species is descriptive for the position of the caudoventral pygofer process, particularly the triangulate apex which can only be seen in dorsal view.

Remarks. From T. lacertosa to which it is similar in configuration of the pygofer caudoventral processes and aedeagus, T. abstrusa can be separated by the longer, narrower caudodorsal processes in lateral and dorsal views (short in lateral view, clawed in dorsal view in T. lacertosa ).
