( Figs 27View FIGURES 25 – 32, 58View FIGURES 57 – 63, 89View FIGURES 88 – 94, 211–212View FIGURES 211 – 222)

Description. Male. Body length 1.73 mm. Color: head and mesosoma dark castaneous; metasoma castaneous. Head ( Fig. 27View FIGURES 25 – 32). Mandible with four distal teeth. Median clypeal lobe ill-defined, with one rounded 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 ecarinate. Metasoma ( Fig. 58View FIGURES 57 – 63). Tergal process lateral, without depression, with very small, low and dorsad tubercle, pit very small, with short tuft of setae. Posterior hypopygeal margin sinuous ( Fig. 89View FIGURES 88 – 94). Genitalia ( Figs 211–212View FIGURES 211 – 222): paramere with dorsal margin wide basally; apical margin truncate. Aedeagal ventral ramus higher than dorsal body, wide, progressively narrowing apicad; cross section laminar; surface horizontal; inner margin straight; outer margin sinuous; apex long, simple, parallel; additional inner ramus absent; basal stub very short and narrow. Aedeagal dorsal body with two pairs of apical lobes; outer lobe very short, horizontal and narrow, with apical margin abruptly acute and slightly mesad; inner pair stout, membranous and setose. Apodeme extending beyond genital ring.

Variation. Pit of tubercle of tergal process without setae.

Remarks. This species is easily recognized by having the dorsal margin of the paramere straight and the apex very excavated in the apical region and the apical lobes of the aedeagal dorsal body very short. This species is similar to D. azagus  sp. nov. by having the dorsal margin of the paramere straight and the apex very excavated. However, this species has the tergal process present, the apical lobes of the aedeagal dorsal body very short and the aedeagal ventral ramus progressively narrowing apicad, whereas D. azagus  sp. nov has the tergal process absent, the apical lobes of the aedeagal dorsal body long and the apex of the aedeagal ventral ramus narrowing abruptly apicad.
