Olidiana vincula , sp. nov.

( Plate 4C , Fig. 210-216 )

Description. Length. Male 8.00 mm., female unknown.

External morphology. Moderately large, robust species. General color black with distinctive markings; forewings black with pale ivory band along apex with large, translucent, triangular spot near middle of costa, narrow, broken, transverse ivory band basad of base of mesonotum; mesonotum black, unmarked; pronotum black with yellow mark below eyes; crown dark brown with black mark next to eyes, dark yellow longitudinal stripe medially; eyes dark brown; face black, long yellow stripe below eyes; head narrower than pronotum, anterior margin broadly rounded; crown short, broad, slightly wider than width of eyes; eyes large, semiglobular; pronotum large, slightly longer medially than crown, surface bullated; mesonotum very large, nearly twice as long medially than pronotum; clypeus long, broad, lateral margins broadly convex; clypellus short, about 1/3 as long as clypeus, broad, narrower than clypeus, apex slightly inflated longitudinally along middle.

Male genitalia. Pygofer in lateral view small, triangular, with small apical lobe, digitate caudoventral process, sparsely setose apically ( Fig. 210 ); aedeagus with shaft long, tubular, very narrow, with long bifurcate, subapical process projecting basally, in lateral and dorsal views with long, glabrous basal process projecting laterally, long setose process distad of basal process, row of short accessory setae on lateral margin ending with long seta distally ( Fig. 211, 212 ); style short, apophysis moderately broad, about as long as base ( Fig. 213, 214 ); dorsal connective very long, narrow ( Fig. 211 ); connective small, anterior arms slightly tapered distally, medial ridge absent ( Fig. 215 ); subgenital plate long, somewhat narrow, glabrous ( Fig. 216 ).

Material examined. Holotype male. Collection I. R. Sc.N.B., THAILAND 21057: Nahao Khong Nam, 12/05/2001, Loei, Leg. P. Grootaert ( IRSNB).

Etymology. The name of the species is descriptive for the narrow, broken, transverse band below base of mesonotum.

Remarks. This species is similar in general habitus to O. inaequibilia but the latter lacks the narrow, yellow transverse band on the forewings. In male genitalia features, O. vincula is distinguished by the narrower apophysis without apical concavity, by the broader arms of the connective and by the row of short accessory processes on the subapical spine on the aedeagus with an extra long, apical accessory process at the base.
