Trinoridia trifida , sp. nov.

( Plate 7F , Fig. 424-430 )

Description. Length. Male 9.80 mm., female unknown.

External morphology. Large, robust species. General color dark brown, cells of forewings translucent, veins marked with yellow stripes; mesonotum tannish with dark brown markings; pronotum black, bullae yellow; crown light brown; eyes dark brown; face dark brown, clypeus and ocellocular area dark tannish; head distinctly narrower than pronotum, anterior margin obtusely rounded; crown short, broad, narrower than width of eyes; eyes large, elongate ovoid; pronotum large, about twice as long medially as crown, surface bullated; mesonotum very large, nearly twice as long as pronotum; forewings with typical venation; clypeus long, narrow, lateral margins broadly convex; clypellus narrow, apex slightly flared laterally.

Male genitalia. Pygofer in lateral view narrowly triangulate, small lobe apically ( Fig. 424 ); aedeagus long, tubular, very narrow, sinuate in lateral view, processes very short, gonopore subapical ( Fig. 425, 426 ); dorsal connective, very long, narrow ( Fig. 427 ); style short, apophysis narrow ( Fig. 428 ); connective large, lateral arms triangulate, lateral margins produced anterior to membrane, medial ridge complete, stem short, digitate ( Fig. 429 ); subgenital plate long, narrow, few microsetae apically ( Fig. 430 ).

Material examined. Holotype male. MALAYSIA: Pahang. 2009, Cameron Highlands, Tanah Rata , vill. envir. ca. 1470-1550 m., 04 o 28.4-7’N. 101 o 21.6-22.1’E, sweeping/beating, P. Banar, M. Tryzna and P. Pacholatko leg. 18 iv. – 15.v. ( MMBC) [second label has Cameroon data, not affiliated with Malaysia].

Etymology. The name of the species is descriptive for the 3 short, glabrous processes on the aedeagus.

Remarks. From T. calcaris to which it is similar in male genitalia, T. trifida can be distinguished by the narrow triangulate pygofer, the larger connective with short ligulate stem and narrower apophysis of the style.
