( Figs 17 View FIGURES 13 – 24 , 48 View FIGURES 45 – 56 , 79 View FIGURES 76 – 87 , 165–166 View FIGURES 163 – 173 )

Description. Male. Body length 2.00 mm. Color: body castaneous. Head ( Fig. 17 View FIGURES 13 – 24 ). Mandible with four distal teeth. Median clypeal lobe ill-defined, with one angulate tooth; median clypeal carina low 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. 48 View FIGURES 45 – 56 ). Tergal process, with lateral, shallow, linear and small depression, without tubercle, pit absent, with very short tuft of setae with one distinctly long seta. Posterior hypopygeal margin weakly concave ( Fig. 79 View FIGURES 76 – 87 ). Genitalia ( Figs 165–166 View FIGURES 163 – 173 ): paramere with dorsal margin wide basally; apical margin truncate. Aedeagal ventral ramus shorter than dorsal body, wide, abruptly narrowing apicad; cross section laminar; surface horizontal; inner margin straight; outer margin slightly sinuous; apex short, simple, angled outward; additional inner ramus absent; basal stub short and very narrow. Aedeagal dorsal body with two pairs of apical lobes; outer lobe short, subvertical and wide with apical margin abruptly acute and dorsad; inner pair stout, membranous and setose. Apodeme not extending beyond genital ring.

Variation. Head, mesosoma and metasoma light castaneous.

Remarks. This species is similar to D. gilvipes by having the dorsal margin of the paramere expanded distally and the aedeagal ventral ramus abruptly narrowing apicad. However, this species has the apical lobes of the aedeagal dorsal body short and wider and the apical margin of the paramere crenulate, whereas D. gilvipes has the apical lobes of the aedeagal dorsal body long and narrow and the apical margin of the paramere smooth.
