( Figs 15View FIGURES 13 – 24, 46View FIGURES 45 – 56, 77View FIGURES 76 – 87, 154–156View FIGURES 148 – 162)

Description. Male. Body length 3.70 mm. Color: head and mesosoma dark castaneous; metasoma castaneous. Head ( Fig. 15View 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 coriaceous; anterior margin ecarinate. Metasoma ( Fig. 46View FIGURES 45 – 56). Tergal process with lateral, shallow, circular and small depression, with small, very low and dorsad tubercle placed on inner area of depression, pit small, with short and sparse tuft of setae. Posterior hypopygeal margin weakly concave ( Fig. 77View FIGURES 76 – 87). Genitalia ( Figs 154–156View FIGURES 148 – 162). Paramere with dorsal margin entirely wide; apical margin truncate. Aedeagal ventral ramus shorter than dorsal body, entirely wide; cross section laminar; surface vertical; inner margin slightly sinuous with small projection in apical portion; outer margin slightly sinuous; apex long, simple, parallel; additional inner ramus long; basal stub short and narrow. Aedeagal dorsal body with pair of apical lobe; outer lobe long, subvertical and narrow, with apical margin rounded and ventrad; inner pair stout, membranous and setose. Apodeme not extending beyond genital ring.

Variations. Body length 3.07 mm (min.) 4.45 mm (max). Tooth of median clypeal lobe rounded; anterior margin of pronotal disc coarse; depression of tergal process very shallow and pit of tubercle large.

Remarks. This species is similar to D. ardonius  sp. nov. by having spine in the ventral margin of the apical lobes of the aedeagal dorsal body and the ventral ramus entirely wide with the inner margin sinuous. However, this species has the dorsal margin of the paramere straight, the apex of the basal bar projected forward and the apical margin of the aedeagal ventral ramus smooth, whereas D. ardonius  sp. nov. has the dorsal margin of the paramere sinuous, the apex of the basal bar not projected forward and the apical margin of the aedeagal ventral ramus wavy.
