Taharana exiquitas , sp. nov.

( Plate 6C , Fig. 339-345 )

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

External morphology. Moderate size, slender species. General color black. Forewings with numerous, brown, irregular shaped markings in cells, veins with short, yellow stripes; mesonotum black with numerous small yellow spots; pronotum black, bullae yellow; crown black with small yellow markings medially; face black with light brown markings on clypeus; head narrower than pronotum, anterior margin obtusely rounded; crown short, narrower than width of eyes, produced anteriorly about ¼ entire length, lateral margins convergent basally; clypeus long, broad, lateral margins parallel; clypellus short, about 1/3 as long as clypeus, narrow, apex flared.

Male genitalia. Pygofer in lateral view triangulate, glabrous, caudoventral process narrowly triangulate apically ( Fig. 339 ), caudodorsal processes in dorsal view long, robust, sinuate, in dorsal view narrow, curved mesally, sub apex slightly concave on inner lateral margin, apex short, digitate ( Fig. 340 ); aedeagus moderately long, tubular, shaft slightly inflated in basal 1/ 3 in ventral view, minute teeth apically on dorsal surface ( Fig. 341, 342 ); style short, apophysis broadly digitate ( Fig. 343 ); dorsal connective moderately long, narrow ( Fig. 341 ); connective broad, arms narrow, medial ridge complete, stem small, ovate ( Fig. 344 ); subgenital plate moderately long, broad medially, glabrous ( Fig. 345 ).

Material examined. Holotype male. THAILAND: Loei, Phu Ruea NP, Ma Kraow ditch, 17 o 29.652’N 101 o 21.020’E, / 1167 m., Pan traps, 6-7.xi.2006, Patikhom Tumtip, leg, T1109 ( QSBG) . Paratype. 1 male, same data as holotype ( MLBM).

Etymology. The species name is descriptive for the small male genitalia features compared to other species.

Remarks. From T. angusta to which it is similar in pygofer caudoventral processes, T. exiquitas can be distinguished by the narrower triangular apex of the pygofer caudoventral processes, shorter subgenital plate, sinuate caudodorsal processes and shorter aedeagus.
