DESCRIPTION. Male ( holotype ). General appearance more or less similar to that of both previous species ( D. laosi sp. n. and D. sjostedti ), but: coloration uniformly whitish with greenish tinge as well as light brown spines of hind tibiae and marks on denticulated parts of cerci; pronotum shorter than in males of these species and almost without humeral notches ( Figs 14–16 ); tegmina strongly shortened (reaching apex of third abdominal tergite) and with stridulatory apparatus distinctly longer than more distal tegminal parts (these parts with only 3 longitudinal veins and narrowly rounded apices) but not completely covered by pronotal hind lobe ( Figs 15, 16 ); hind wings invisible (absent?); subapical tergite without posterolateral projections; last tergite with almost widely rounded posterior edge; cerci long, clearly arcuate, moderately thin, with laterally flattened but not widened distal parts, with thin and straight medial spine on each cercal base (this spine finely denticulated) which not pressed to main cercal body, and with ventromedial angular projection at middle of this cercal body (this projection horizontally lamellar, posteromedially denticulated and connected with low, long and denticulated ventromedial keel along more distal part of this cercal body; Figs 38–40 ); genital plate wide but with strongly narrowed distal part having thin styles and distinct angularly rounded notch between them ( Fig. 39, 40 ). Genitalia with sclerotized part long, narrow and mostly semimembranous but having a pair of thin and rather long spines slightly arcuate in proximal parts ( Fig. 17 ). Female unknown. Length (in mm). Body 7.8; pronotum 3.2; visible parts of tegmina 1.8; hind femora 8.4. COMPARISON. The new species is somewhat similar to D. ( D .) brachyptera Chang, Du et Shi, 2013 from Taiwan and to D. abruptum Gorochov, 2012 from Sulawesi in strongly shortened wings. However: it differs from D . ( D .) brachyptera in narrower distal parts of the male cerci, the presence of a lamellar ventromedial projection at the middle of each male cercus, and a less arcuate proximedial spine of this cercus; from D. abruptum , lacking known male, the new species is distinguished by the absence of distinct yellowish stripes along the lateral edges of the pronotal disc and slightly less low pronotal lateral lobes. And from all other congeners, it differs in strongly shortened wings and some features of body coloration and of abdominal structure (including shape of spines in the male genitalia).
