Description. Male. Body small sized. Head with fastigium of vertex divided into two conical tubercles. Legs long and slender; fore femora about 1.6 times as long as the pronotum, beneath unarmed, internal knee lobe without spines, genicular lobe with 1 long movable spur; fore tibia beneath with 2 external and 2 internal spurs, between the paired apical spurs with a short spur. Mid femora with a long movable spur on the internal and genicular lobe, mid tibia beneath with 2 external and 1 internal spur, between the paired apical spurs with a short spur. Hind femora beneath with 4–5 inter spines and without outer spines; hind tibia above with 44–47 outer spines and 39–42 inter spines, arrange in clusters, inner subapical spur of hind tibia longer than hind metatarsus. Hind metatarsus with 2 dorsal spines. Apical half of male paraproct slightly compressed ( Fig. 46 ). Apex of process of male 7th abdominal tergite rather short and narrow ( Fig. 47 ). Male genitalia with notched apex of rather long dorso-median lobe and lateral lobes quite short ( Fig. 48 ).

Female. Subgenital plate nearly rounded and with a truncated apex ( Fig. 49 ). Ovipositor longer than the half of hind femora.

Coloration. Body light brown. Face with 4 darkish longitudinal bands. Legs with distinct dark marks.

Measurements. (length in mm) Body Ƌ 10.0–15.0, ♀9.0–15.0; Pronotum Ƌ 4.0–6.0, ♀ 4.0–5.0; Fore femora Ƌ 7.5–9.5, ♀ 7.0–9.0; Hind femora Ƌ 17.0–20.0, ♀ 16.0–18.0; Hind tibia Ƌ 17.0–20.0, ♀16.0–18.0; Ovipositor ♀ 11.0–14.0.

Material examined. Holotype, 1♂, Lushui, Yunnan, 2300m, 2010. VI.24–25, collected by Bi Wen-Xuan et al., paratype, 6ƋƋ, 9♀♀, same data as holotype; 2ƋƋ, 1♀, Gongshan, Yunnan, 1900m, 2010. VI.28–VII.3, collected by Bi Wen-Xuan et al ..

Distribution. China (Yunnan).

Discussion. This new species is similar to D. brevis sp. nov. and D. emeiensis sp. nov., but differs as follows: spines on hind tibia arrange in clusters, inner subapical spur longer than hind metatarsus.
