Fore femora about three times as long as the pronotum, femora unarmed on ventral surface, internal genicular lobe with one small spine, external genicular lobe with one long spine; tibiae with two external and two internal spines on ventral surface, apex with one pair of dorsal spines and one pair of ventral spines, one spinule between two ventral end spines. Middle femora unarmed on ventral surface and with 1 movable spine on the internal and external genicular lobes respectively middle tibiae ventrally with two internal and two external spines, apex with one pair of dorsal spines and one pair of ventral spines, one spinule between two ventral end spines. Hind femora ventrally with 12–15 inner spines; tibiae with 33–35 internal spinules and 29–33 external spinules on dorsal surface, subapex with one pair of dorsal spines, apex with one pair of dorsal spines and two pairs of ventral spines; hind metatarsus dorsally with 2–3 spinules ( Fig. 4G–H ). Apex of paraproct blunt. Posteromedian process of 7th abdominal tergite elongate, obviously surpassing apex of paraproct, base of posteromedian process broad, gradually narrowing, the middle area curved downward, apex blunt ( Fig. 4C, E–F ).

Female. Base of ovipositor broad, narrowing to apex, dorsal valvulae smooth, ventral valvulae ventrally denticulate on apical area.

Coloration. Face with four longitudinal black stripes. All tergites laterally with a few irregular light marks ( Fig. 4D ). Hind femora basal half with irregular black stripes on upper half part, and apical half with 2 annular black stripes ( Fig. 4I ).

Measurements (in mm). Length of body ♁30.6, ♀ 30.1; length of pronotum ♁8.7, ♀ 9.3; length of fore femora ♁23.9, ♀ 28.2; length of hind femora ♁42.7, ♀ 46.4; length of hind tibiae ♁47.6, ♀ 51.2; length of hind basitarsi ♁11.48, ♀ 12.3; length of ovipositor 29.6.

The new species is similar to D. palpata Rehn, 1906 and D. cryptopygia (Chopard, 1918) , but differs from D. palpata in the dorsal plate of the male 7th abdominal tergite not bifurcated and the paraproct slender; differ from D. cryptopygia in male 7th abdominal tergite not bifurcated and the paraproct not suddenly narrowly on apical part.
