( Figs 13 View FIGURES 13 – 24 , 44 View FIGURES 33 – 44 , 75 View FIGURES 64 – 75 , 142–144 View FIGURES 136 – 147 )

Description. Male. Body length 4.78 mm. Color: body castaneous. Head ( Fig. 13 View FIGURES 13 – 24 ). Mandible with two distal teeth. Median clypeal lobe trapezoidal, with one angulate tooth; median clypeal carina high in profile, complete or nearly so, straight in profile or nearly so. Frons weakly coriaceous and punctures small. Vertex crest weakly concave. Pronotal disc weakly coriaceous; anterior margin coarse. Metasoma ( Fig. 44 View FIGURES 33 – 44 ). Tergal process lateral with shallow, subcircular and large depression, with small, low and dorsad tubercle placed on anterior area of depression, pit large, with short and sparse tuft of setae. Posterior hypopygeal margin sinuous ( Fig. 75 View FIGURES 64 – 75 ). Genitalia ( Figs 142–144 View FIGURES 136 – 147 ): paramere with dorsal margin entirely wide; apical margin truncate. Aedeagal ventral ramus shorter than dorsal body, entirely wide with small projection apicad; cross section laminar; surface vertical; inner margin sinuous, outer margin sinuous; apex short, simple, parallel; additional inner ramus long; basal stub absent. Aedeagal dorsal body with two pairs of apical lobes; outer lobe, long, vertical and very narrow, with apical margin crenulate and posterad; inner pair, stout, membranous and setose. Apodeme not extending beyond genital ring.

Variations. Body length 3.31 (min.) mm and 6.06 mm (max.). Depression of tergal process deep or very shallow.

Remarks. This species is easily recognized by having the ventral margin of the apical lobes of the aedeagal dorsal body deeply excavated, the apex of the basal with apex projected forward, the aedeagal ventral ramus vertical and the apex with a small projection dorsad. This species is similar to D. arteus sp. nov. by having the dorsal margin of the paramere sinuous, the apex of the basal bar projected forward and the inner margin of the aedeagal ventral ramus crenulate. However, this species has the apex of the basal bar crenulate, the ventral margin of the aedeagal dorsal body deeply excavated and the apical margin of the aedeagal dorsal body with small dorsad projection, whereas D. arteus sp. nov. has the apex of the basal bar smooth, the ventral margin of the apical lobes of the aedeagal dorsal body not excavated and the aedeagal ventral ramus without projection.
