Trinoridia calcaris , sp. nov.

( Plate 7G , Fig. 431-436 )

Description. Length. Male 8.14 mm., female unknown.

External morphology. Moderately large, robust species. General color light brown with very small to large, dark brown spots on forewings, central, medial and inner preapical cells translucent; mesonotum ivory, with large, black triangular spot in upper, lateral corners, numerous light brown markings medially; pronotum dark brown, bullae yellow; crown light brown; eyes dark brown; face yellow, clypeus with short, transverse black stripes on inner lateral margins; clypellus yellow with light brown, longitudinal stripe medially; head narrower than pronotum, broadly rounded anteriorly; crown narrow, narrower than width of eyes, slightly produced anteriorly, lateral margins convergent basally; pronotum large, about 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 short, abut 1/3 as long as clypeus, lateral margins narrow, slightly flared apically.

Male genitalia. Pygofer in lateral view broadly triangulate, small lobe apically, caudoventral margin with small digitate process ( Fig. 431 ); aedeagus long, tubular, very narrow, in dorsal view with moderately long, slender, glabrous apical and subapical spines, small spur basad of distal spines, gonopore subapical ( Fig. 432, 433 ); style very short, apophysis broad ( Fig. 434 ); dorsal connective long, narrow ( Fig. 432 ); connective large, anterior arms triangulate, lateral margins produced anteriorly, medial ridge complete, stem large, ovate ( Fig. 435 ); subgenital plate long, broad, outer margin broadly convex along middle, sparsely setose along outer lateral margin ( Fig. 436 ).

Material examined. Holotype male. INDIA: Tamil Nadu, 32 km. E. Kodaikanal, 1050 m., Sept. 25, 1985, C.W. and L.B. O’Brien / Brit. Mus. 1992-118. ( BMNH).

Etymology. The name of the species is descriptive for the small processes on the aedeagus.

Remarks. The species is nearest to T. trifida and can be separated by the broad triangulate pygofer, presence of the caudoventral process and smaller connective and style.
