( Figs 11 View FIGURES 1 – 12 , 42 View FIGURES 33 – 44 , 73 View FIGURES 64 – 75 , 138–139 View FIGURES 136 – 147 )

Description. Male. Body length 4.0 mm. Color: body dark castaneous. Head ( Fig. 11 View FIGURES 1 – 12 ). Mandible with two distal teeth. Median clypeal lobe trapezoidal, with one angulate tooth; median clypeal carina low in profile, incomplete apically, straight in profile or nearly so. Frons weakly coriaceous and punctures small. Vertex crest straight. Pronotal disc coriaceous; anterior margin coarse. Metasoma ( Fig. 42 View FIGURES 33 – 44 ). Tergal process lateral, without depression, low and dorsad tubercle, pit small, with short and dense tuft of setae. Posterior hypopygeal margin weakly concave ( Fig. 73 View FIGURES 64 – 75 ). Genitalia ( Figs 138–139 View FIGURES 136 – 147 ): paramere with dorsal margin entirely wide; apical margin truncate. Aedeagal ventral ramus higher than dorsal body, wide, progressively narrowing apicad; cross section laminar; surface horizontal; inner margin excavated; outer margin sinuous; apex short, translucent, wavy, parallel, additional inner ramus short; basal stub absent. Aedeagal dorsal body with two pairs of apical lobes; outer lobe short, subhorizontal and wide, with apical margin rounded and ventrad; inner pair stout, membranous and setose. Apodeme extending beyond genital ring.

Variations. Tergal process closer to each other; tubercle higher or with few setae.

Remarks. This species is easily recognized by having the paramere narrow with the dorsal margin straight, very acute apex, the basivolsella wavy and the basal bar in the median portion of the aedeagal dorsal body projected forward. This species is similar to the D. cervoides by having the apex of the aedeagal ventral ramus laminar, translucent with two expansions. However, this species has the paramere narrow, the aedeagal ventral ramus wide with the inner margin of the apex smooth and the basivolsella wavy, whereas D. cervoides has the paramere not so straight, the aedeagal ventral ramus narrower with the inner margin of the apex serrated and the basivolsella not wavy.
