Fore tibia with 4 dorsal bristles, of which the upmost is the longest. Dorsal hair palisade of mid tibia extends up to 2/3 of its length. Hind tibia without dorsal isolated bristles. Posterior face of hind femur with 2 peg-like bristles, which are very long and blunt at top, beside them are 2–3 small bristles or hairs, and dorsally with 1–3 hairs just below dorsal edge. Hind coxal lobe hemispheric. Abdomen. Tergite I yellow on anterior half and dark brown on posterior edge. Tergites II–V yellow with brownish lateral region. Tergite VI dark brown with yellowish anterior edge. Venter of abdomen yellow. Terminalia brown, except cercus yellow.

Etymology. The specific epithet refers to the long peg-like bristles on posterior face of hind femur..

Holotype: ♂, Zhejiang, Mt. Tianmu (30°21'N, 119°25'E, 1334m), 30-VI-2013, Lixin Su.

Remarks. The species can be easily distinguished from other species of the genus by its special long peg-like bristles. In Disney's key (1990a), the species runs to couplet 23 to D. caini Disney. However , the new species is easily distinguished by the very long peg-like bristles on posterior face of hind femur.
