( Figs 20 View FIGURES 13 – 24 , 51 View FIGURES 45 – 56 , 82 View FIGURES 76 – 87 , 180–181 View FIGURES 174 – 183 )
Description. Male. Body length 1.73 mm. Color: head castaneous; mesosoma and metasoma light castaneous. Head ( Fig. 20 View FIGURES 13 – 24 ). Mandible with four distal teeth. Median clypeal lobe ill-defined, with one rounded very short tooth; median clypeal carina high in profile, incomplete apically, convex in profile. Frons weakly coriaceous and punctures small. Vertex crest straight. Pronotal disc weakly coriaceous; anterior margin ecarinate. Metasoma ( Fig. 51 View FIGURES 45 – 56 ). Tergal process with lateral, shallow, circular and large depression, with small, low and dorsad tubercle placed on center of depression, pit small, with short tuft of setae. Posterior hypopygeal margin strongly concave ( Fig. 82 View FIGURES 76 – 87 ). Genitalia ( Figs 180–181 View FIGURES 174 – 183 ): paramere with dorsal margin entirely wide; apical margin truncate. Aedeagal ventral ramus shorter than dorsal body, wide, abruptly narrowing apicad; cross section laminar; ramous bifid, surface horizontal; inner margin sinuous; outer margin sinuous; apex short, simple, parallel; additional inner ramus absent; basal stub 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 laterad; inner pair stout, membranous and setose. Apodeme extending beyond genital ring.
Remarks. This species is the most different in setosus species-group by having the aedeagal dorsal body elongated and very short apical lobes of the aedeagal dorsal body. These characters are easy to be recognized. This species is similar to D. filus , by having the aedeagal dorsal body elongated with small apical lobes of the aedeagal dorsal body. However, this species has the paramere the same size as the basiparamere, the apical lobes of the aedeagal dorsal body very short and wide and the aedeagal ventral ramus bifid whereas D. filus has the paramere longer than basiparamere, the apical lobes of the aedeagal dorsal body longer and narrow and the aedeagal ventral ramus not bifid. The base of the aedeagal ventral ramus has small lamelar projections that are difficult to see in magnifying glass, but easily seem in microscope. In this species-group just this species and D. w-aedeagus has the ventral ramus bifid.
