Diagnosis. — Male. Length 2.94 mm . Mandible bidentate. Clypeus trapezoidal. Frons coriaceous, with small punctures. Vertex straight, with rounded corners. Metasomal tergite II with pair of rounded and shallow lateral depressions, distant each other 1.5 X their diameters, with an anterior tubercle with tuft of long hairs slightly directed inward ( Fig. 29 ). Genitalia ( Figs. 30–31 ): paramere with acute apex and arched inward, dorsal margin much developed, mainly at the base ( Fig. 32 ); aedeagus with ventral ramus short, as high as base of cuspis, wide, inner and outer margins straight and slightly convergent, apex acute with outer margin slightly concave, ramus laminar, surface vertical; dorsal body with two pairs of apical lobes, outer pair laminar, wide with rounded apex in lateral view, compressed in dorsal view, wider below the apex, inner pair elongate, membranous, hairy; apodeme not extending beyond the elliptical basal ring. Material examined. HOLOTYPE : male, SAINT VINCENT , 244, H. H. Smith col. ( USNM #2494 ). Here designated as lectotype . Comments. — The original description was based on two specimens . It is very similar to D. plaumanni Evans by tergal process and genitalia, except by the paramere which is thinner apically than in D. plaumanni . In addition, the mandible is bidentate in D. tuberculatus , but tetradentate in D. plaumanni .
