Taharana sublamina , sp. nov.

( Plate 5D , Fig. 282-288 )

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

External morphology. Moderate size, slender species. General color black; forewings black, veins with short, yellow stripes, cells with brown, irregularly shaped markings; mesonotum black, with few small, yellow spots; pronotum black, bullae yellow; crown dark brown; eyes dark brown; face light brown except for black clypellus; head narrower than pronotum, anterior margin somewhat narrowly rounded; crown short, narrower than width of eyes, slightly produced anteriorly, lateral margins convergent basally; pronotum moderately large, slightly longer medially than 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 triangulate, glabrous, with long narrow caudodorsal process, pointed apically, caudoventral process long, curved, tapered apically, without serrations on ventral margin ( Fig. 282 ), in dorsal view processes slightly broad in apical 1/3, obliquely truncate apically ( Fig. 283 ); aedeagus long, shaft inflated in basal 2/ 5 in dorsal and lateral views, patch of small teeth on dorsoapical margin ( Fig. 284, 285 ); style in lateral view very small, apophysis curved, digitate ( Fig. 286 ); dorsal connective long, narrow ( Fig. 284 ); connective moderately large, anterior arms broad, medial ridge absent, stem small, sub-ovate ( Fig. 287 ); subgenital plate long, broad, glabrous ( Fig. 288 ).

Material examined. Holotype male. THAILAND: Chaiyaphum, Pa Hin Ngam NP, Dry evergreen / forest at waterfall, 15 o 34.802’N 101 o 25.990’E., 430 m., Pan traps, 12- / 13.xi.2006, Katae Sa-nog and Bua- Kaw Adnafai, leg. T1024 ( QSBG) . Paratype, 1 male, same data as holotype except T 1638 ( MLBM).

Etymology. The name of the species is descriptive for the near blade-like caudoventral pygofer process.

Remarks. From T. forcipia to which it is similar in configuration of caudoventral pygofer process and inflated aedeagus, T. sublamina can be separated by the following combinations of features: long tapered caudodorsal process in lateral view, broad, obliquely truncate in dorsal view, narrower, tapered caudoventral pygofer process and by the larger anterior arms of the connective.
