sp. nov.

Taharana truncata , sp. nov.

( Plate 6A View PLATE 6 , Fig. 325-331 View Figures 325-331 )

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

External morphology. Moderate size, slightly robust species. General color black. Forewings black, cells with numerous, irregularly shaped light brown markings, veins marked with short, dark yellow stripes; mesonotum black with small dark yellow spots; pronotum black, bullae dark yellow; crown black with margins dark yellow; eyes dark yellow with black patches; face dark brown, ocellocular area dark yellow; head narrower than pronotum, anterior margin broadly rounded; crown moderately long, narrower than width of eyes, produced anteriorly about ¼ of entire medial length, lateral margins convergent basally; eyes large, pronotum short, moderately large, about as long medially as crown, surface bullated; mesonotum large, nearly twice as long medially as pronotum; clypeus long, broad, lateral margins broadly convex; clypellus short, about 1/3 as long as clypeus, narrow, apex flared.

Male genitalia. Pygofer in lateral view broadly triangulate, glabrous, caudodorsal processes long, sinuate, tapered apically, caudoventral processes narrow throughout length except for apex, obliquely truncate apically ( Fig. 325 View Figures 325-331 ), in dorsal view processes narrow in basal 2/3, curved mesally and broadened in subapical 1/3, with apex short, digitate ( Fig. 326 View Figures 325-331 ); aedeagus long, tubular, shaft inflated in nearly basal 1/ 3 in ventral and lateral views, finely toothed on dorsal surface in distal 1/5 ( Fig. 327, 328 View Figures 325-331 ); style small, apophysis short, digitate ( Fig. 327 View Figures 325-331 ), dorsal connective long, narrow ( Fig. 329 View Figures 325-331 ); connective moderately large, arms broad, tapered anteriorly, medial ridge nearly complete, stem small, semi ovate ( Fig. 330 View Figures 325-331 ); subgenital plate long, broad medially, slightly tapered apically, glabrous ( Fig. 331 View Figures 325-331 ).

Material examined. Holotype male. THAILAND: Loei Phu Ruea NP, Old road to the park, 17 o 27.901’N 101 o 21.301’E, 700 m. / Malaise trap, 26.xii.2006 – 2.i.2007, Patikom Tumtip, leg. T1272 ( QSBG). GoogleMaps

Etymology. The name of the species is descriptive for the truncate caudoventral pygofer processes.

Remarks. Taharana truncata is unique for its truncate caudoventral pygofer processes and triangular shape apex of the pygofer caudodorsal processes, all of which will distinguish the species from all known species.
