Taharana phetchabunensis , sp. nov.

( Plate 6F , Fig. 361-367 )

Description. Length. Male 7.30-7.90 mm., female unknown.

External morphology. Moderate size, slender species. General color dark brown to black. Forewings with short, yellow stripes on veins, cells with numerous, small, irregular shaped brown spots; mesonotum black with small, yellow spots; pronotum black, bullae yellow; crown brown to black, with dark brown to black markings; eyes light to dark brown; face yellow with reddish brown longitudinal stripe on inner lateral margins of clypeus, clypellus with suffused, narrow, longitudinal stripe medially; head narrower than pronotum, anterior margin obtusely rounded; crown short, slightly narrower than width of eyes, produced about ¼ entire length, lateral margins convergent basally; eyes large, semiglobular; pronotum large, nearly twice as long as crown; surface bullated; mesonotum large, about 1/3 longer medially than pronotum; clypeus long, narrow, lateral margins broadly convex; clypellus short, about 1/3 as long as clypeus, slightly inflated longitudinally along middle, narrow, apex flared laterally.

Male genitalia. Pygofer in lateral view triangulate, glabrous, tapered to blunt point, caudoventral process very long, narrowly laminate, serrated on ventral margin about apical half, small spine on dorsoapical margin ( Fig. 361 ), in dorsal view caudodorsal processes very broad, slightly tapered and curved apically with few microsetae ( Fig. 362 ); aedeagus long, tubular, shaft broad in basal ¼ in dorsal view, small patch of small teeth in apical 1/7, gonopore in apical 4/5 ( Fig. 363, 364 ); style very small, base large, short narrow apophysis ( Fig. 365 ); dorsal connective long, narrow ( Fig. 366 ); connective small, arms narrow, medial ridge incomplete, stem large, ovate ( Fig. 363 ); subgenital plate long, broad, glabrous ( Fig. 367 ).

Material examined. Holotype male. THAILAND: Phetchabun, Nam Nao NP., Forest protection unit - Huay Praelard / cave, 16 o 44.964’N 101 o 27.833’E., 711 m., Pan traps / 21.i.2007 - 22.i.2007, Noopean Hongyothi – Leng Janteab, leg. T1620 ( QSBG) . Additional material examined: Paratypes: 1 male, same data as holotype ( QSBG) ; 3 males, same data as holotype except 20-21.i.2007, T1619 ( QSBG) ; 2 males, same data as holotype except 16-17.i.2007, T1615 ( MLBM, ULKY) ; 1 male, same data as holotype, 18- 19.i.2007, T1617 ( QSBG) ; 1 male, same data as holotype except 19-20.i.2007, T1618 ( QSBG) ; 1 male, same data as holotype, 7-14.viii.2006 T424 ( QSBG) ; 44 males, same data as holotype except various collecting dates and T numbers ( QSBG) .

Etymology. The name of the species is after the collection locality of Phetchabun which produced 54 specimens, all collected in pan traps.

Remarks. The species is nearest to T. incisura and can be separated by the shorter subgenital plate, shorter inflated base of the aedeagal shaft, longer dorsal connective, smaller and broader arms of the connective, broader apical 1/4 of the pygofer and shorter row of ventral teeth with caudodorsal spine on the pygofer caudoventral process.
