( Plate 3I , Fig. 189-195 ) Description. Length. Male 7.50 mm., female unknown. External morphology. Moderately long, slightly robust species. General color black with numerous, tiny yellow markings on pronotum, mesonotum and forewings; crown dark brown, marked by black spots; eyes dark brown; face pale yellow with 2 orange, longitudinal stripes in inner lateral margins of clypeus; clypeus dark orange; head narrower than pronotum, obtusely rounded anteriorly; crown narrow, narrower than width of eyes, slightly produced anteriorly beyond eyes, lateral margins convergent basally; eyes large, elongate ovoid; pronotum large, slightly longer medially than crown, surface bullated; mesonotum very large, nearly twice as long medially than pronotum; venation of forewings typical; clypeus long, narrow, lateral margins broadly convex; clypellus short, narrow, about 1/3 as long as clypeus, apex inflated laterally. Male genitalia. Pygofer in lateral view triangulate, small lobe apically, small digitate caudoventral lobe, glabrous ( Fig. 189 ); aedeagus long, tubular sinuate in dorsal and lateral views, shaft inflated in basal 1/3, in dorsal view, apical process recurved, bifurcate, each arm long, outer arm with medial process, toothed apically, outer arm with basal spur, serrate in distal half ( Fig. 190, 191 ); style very long, in dorsal view apophysis narrow in distal half, in lateral view apophysis very broad, constricted in apical 1/ 3, slightly concave apically ( Fig. 192, 193 ); dorsal connective short, narrow ( Fig. 190 ); connective moderately large, anterior arms narrow with median ridge, stem very small, sub-ovate ( Fig. 194 ); subgenital plate long, with few short microsetae on inner lateral margin in apical 1/6 ( Fig. 195 ). Material examined. Holotype male. VIETNAM : [ Ninh Binh ]: Cuc Phuong , 11-18-viii-2010 , IG 31.668 , Leg. J. Constant and P. Limbourg ( IRSNB ). Etymology. The name of the species is descriptive for the 2 digitate, apical processes of the aedeagus. Remarks. From O. bispiculata , sp. nov. to which it is similar in aedeagal features, tuberis can be distinguished by the long robust style in lateral view, narrow subgenital plate and presence of a digitate caudoventral process on the pygofer.
