( Figs 22View FIGURES 13 – 24, 53View FIGURES 45 – 56, 84View FIGURES 76 – 87, 184–185View FIGURES 184 – 197)

Description. Male. Body length 1.85 mm. Color: head and mesosoma dark castaneous; metasoma castaneous. Head ( Fig. 22View FIGURES 13 – 24). Mandible with two distal teeth. Median clypeal lobe subtrapezoidal, 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 ecarinate. Metasoma ( Fig. 53View FIGURES 45 – 56). Tergal process with lateral, shallow, subcircular and small depression, with small, high and dorsad tubercle placed on center of depression, pit small, with short and dense tuft of setae. Posterior hypopygeal margin straight or nearly so ( Fig. 84View FIGURES 76 – 87). Genitalia ( Figs 184–185View FIGURES 184 – 197): paramere with dorsal margin wide basally; apical margin truncate. Aedeagal ventral ramus as long as dorsal body, wide, progressively narrowing apicad; cross section laminar; surface subhorizontal; inner margin straight; outer margin slightly sinuous; apex long, simple, slightly curved inward; additional inner ramus absent; basal stub short and very narrow. Aedeagal dorsal body with pair of apical lobe; outer lobe short, horizontal and very narrow, with apical margin abruptly acute and ventrad; inner pair stout, membranous and setose. Apodeme extending beyond genital ring.

Variations. Depression of tergal process very shallow, tubercle low; apical lobe of aedeagal dorsal body longer and narrower.

Remarks. This species is similar to D. areius  sp. nov. by having the paramere excavated apically and expanded basally and the aedeagal dorsal body with three narrow and long filaments which connect the apical lobes of the aedeagal dorsal body to the basal portion of the aedeagal dorsal body. However, this species has the apex of apical lobes of the aedeagal dorsal body abruptly acute and the aedeagal ventral ramus with the apex toothed, whereas D. areius  sp. nov. has the apex of the apical lobes of the aedeagal dorsal body with a small laterad projection and the aedeagal ventral ramus with the apex translucent and smooth.
