sp. nov.

Taharana forcipia , sp. nov.

( Plate 7C View Plate 7 , Fig. 403-409 View Figures 403-409 )

Description. Length. Male 7.30-7.70 mm., female unknown.

External morphology. Moderate size, slender species. General color black; forewings black with small, dark yellow stripes on veins, numerous small, irregular shape, light brown markings in cells; mesonotum black with dark yellow spots; pronotum black, surface with numerous, dark yellow bullae; crown light to dark yellow with narrow black stripe on each side of middle; eyes light to dark yellow; face light yellow; clypeus with narrow, longitudinal, reddish brown stripe on inside of lateral margins; clypellus with suffused orange longitudinal stripe medially; head narrower than pronotum, anterior margin broadly rounded; crown short, narrower than width of eyes, slightly produced anteriorly, lateral margins convergent basally; eyes large, semiglobular; clypeus long, narrow, lateral margins broadly convex, sinuate; clypellus short, narrow, apex flared laterally.

Male genitalia. Pygofer small, glabrous, with narrow, broadly curved caudodorsal process, caudoventral process long, ventral margin broad along middle, tapered to sharp point apically, ventral margin minutely serrate ( Fig. 403 View Figures 403-409 ), in dorsal view caudodorsal processes caliperate ( Fig. 404 View Figures 403-409 ); aedeagus moderately long, tubular, shaft inflated in basal 1/ 3 in ventral view, narrow in distal 2/3, patch of small teeth on dorsoapical margin, gonopore in distal ¾ ( Fig. 405, 406 View Figures 403-409 ); style very small, short apophysis ( Fig. 407 View Figures 403-409 ); dorsal connective moderately long, narrow ( Fig. 404 View Figures 403-409 ); connective small, anterior arms narrow, medial ridge absent, stem short, digitate ( Fig. 408 View Figures 403-409 ); subgenital plate moderately long, broad, glabrous ( Fig. 409 View Figures 403-409 ).

Material examined. Holotype male. THAILAND: Ubon, Ratchathani, Pha Taem NP., Rong Hi Noy, 15 o 40.021’N / 105 o 30.448’E, 240 m., Malaise trap, 7-14.i.2007, Thongkam and Pakdee, leg. T1479 ( QSBG) GoogleMaps . Paratypes. 3 males, same data as holotype except First level- Huay / Sannom waterfall, 15 o 27.407' N 105 o 34.867’E., 230 m. Pan traps, 6.v.2007, Sorowit Mingnan, leg., T 2180 ( QSBG, ULKY).

Etymology. The name of the species is descriptive for the forceps-like caudodorsal pygofer processes in dorsal view.

Remarks. This species is nearest to T. serrata in shape of the caudoventral process of the pygofer and can be separated by the smaller pygofer with shorter, curved, caudodorsal process in lateral view (very long, slender with subapical spine in T. serrata ), by the narrower aedeagal shaft in lateral view and by the subgenital plate which is broader throughout.
