Description.
Male. Body length
2.24 mm
. Color: body dark castaneous. Head (
Fig. 7
). Mandible with two distal teeth. Median clypeal lobe ill-defined, with one angulate very short tooth; median clypeal carina low in profile, incomplete apically, angled in profile. Frons weakly coriaceous and punctures small. Vertex crest weakly concave. Pronotal disc coriaceous; anterior margin carinate. Metasoma (
Fig. 38
). Tergal process with shallow, subcircular and large depression, with very small and very low dorsad tubercle placed on inner area of depression, pit very small with short tuft of setae. Posterior hypopygeal margin weakly concave (
Fig. 69
). Genitalia (
Figs 127–128
): paramere with dorsal margin entirely wide; apical margin truncate. Aedeagal ventral ramus shorter than dorsal body, wide, abruptly narrowing apicad; cross section laminar; surface subvertical; inner margin sinuous; outer margin sinuous; apex long, crenulate, curved outward; additional inner ramus absent; basal stub absent. Aedeagal dorsal body with two pairs of apical lobes; outer lobe long, horizontal and wide, with apical margin crenulate and laterad; inner pair stout, membranous and setose. Apodeme not extending beyond genital ring.
Variations.
Body length between 1.79 (min.) mm and 2.60 (max.) mm.
Remarks.
This species is similar to
D. asitius
sp. nov.
by having the aedeagal ventral ramus with toothed apex and the paramere with crenulate apex. However, it species has the apical lobes of the aedeagal dorsal body long, with laterad apex and the paramere with the dorsal margin sinuous, whereas
D. asitius
sp. nov.
has the apical lobes of the aedeagal dorsal body shorter with dorsad apex and the paramere with the dorsal margin almost straight.
