Description. Male. Body small (10–13 mm). Median ocellus oval and lateral ocelli circular situated on lateral surface of basal fastigium verticis. Posteromedian projection of 7 th abdominal tergite long, obviously surpassing apices of paraproct (Fig. 10E & F; Fig. 11A). The first half concaved laterally from the sides (Fig. 10E; Fig. 11A), second half flat and parallel curving downwards. The apex slightly curved inwards or downward (Fig. 10E; Fig. 11C), apical area of posteromedian projection dichotomous and acute when viewed from ventral side (Fig. 10C & E; Fig. 11C). Paraproct rather long (not as long as D. tsongkhapa), proximal half broad, narrowing towards apex, obtuse, slightly curved from middle directing backward. Subgenital plate similar to sister species D. tsongkhapa (Fig. 6). Cerci slender, conical, apices obtuse. Linear measures of body elements (Table 2). Fore and mid leg spine details as per the generic description. Hind leg spine details (Table 3).

Colouration. Head dorsally yellowish or white and black. The body is mostly very dark to black with or without small pale spots and numerous short black and yellow hairs. A pale dorsomedial stripe (think or thin) extends from the pronotum to the 2 nd or 6 th abdominal tergite (Fig. 10F). White spots possible on metanotum and 1 st tergite (Fig.10F). Paraproct black. Cerci black with white on ventral and basal parts, and with dense short yellowish-brown hairs and few long pale hairs at the base (Fig. 10C).

Female. Body colour darker than male without white spots on metanotum and 1 st abdominal tergite. Median line is rather thin extending only until 2 nd abdominal tergite. Posteromedian projection of 7 th abdominal tergite short and angular with posteromedial apex rounded completely covering 8 th abdominal tergite (Fig. 11D). Subgenital plate almost translucent, broad and short, almost convex with obtusely rounded apex (Fig. 11F). Ovipositor slightly longer than body length, thin. Upper valves broad and apex acute. Lower valves with numerous fine teeth from below the apex (Fig. 11). Size of body elements (Table 2) and leg spine combination (Table 3) are similar to male.

Etymology. The new species is named in honour of late Dr. Phub Dorji, the first president of the College of Natural Resources, Royal University of Bhutan.
