( Plate 6B , Fig. 332-338 ) Description. Length. Male 7.60 mm., female unknown. External morphology. Moderately large, slender species. General color black. Forewings with numerous, irregularly shaped brown spots in cells, veins with short, dark yellow stripes; mesonotum black; pronotum black, bullae dark yellow; crown black with small, dark brown spots, some contiguous; eyes light brown; clypeus black, with few short, dark yellow, transverse stripes on middle of lateral margins, rest of face light tan; head narrower than pronotum, anterior margin narrowly rounded; crown narrower than width of eyes, slightly produced anteriorly, lateral margins convergent basally; eyes large, semiglobular; clypeus long, broad, lateral margins broadly convex, clypellus short, about 1/3 as long as clypeus, narrow, slightly inflated longitudinally along middle, apex flared. Male genitalia. Male pygofer in lateral view narrowly triangulate, glabrous, caudodorsal process short, slightly curved dorsally, apex truncate, caudoventral process with triangulate apex ( Fig. 332 ), in dorsal view narrow, curved mesally in apical 1/3, apex pointed ( Fig. 333 ); aedeagus moderately long, tubular, shaft in ventral view inflated in basal 1/3, finely toothed in distal 1/5 on dorsal margin ( Fig. 334, 335 ); style in lateral view small, apophysis digitate, about as long as base ( Fig. 336 ); dorsal connective long, narrow ( Fig. 334 ); connective moderate size, arms tapered distally, medial ridge nearly complete, stem ovate ( Fig. 337 ); subgenital plate long, broad, glabrous ( Fig. 338 ).

Paratype male, same data as holotype ( MLBM ). Etymology. The name of this species is descriptive for the narrow caudodorsal processes of the pygofer in dorsal view. Remarks. From T. brevicutata to which it has similar caudoventral processes, T. angusta can be separated by the much narrower caudodorsal processes in dorsal view and by the much longer subgenital plate with evenly tapered apex.
