Antenna reaching pronotal posterior end; scape robust, distally strongly swollen and bearing dense, short, and thick setae, nearly 1.5 times as long as wide, nearly twice as long as pedicel; pedicel as long as wide, nearly half as long as flagellomere 1; flagellum with c. 38 segments; flagellomere 1 long, nearly 1.5 times as long as wide, nearly twice as long as following flagellomere; remaining flagellomeres each nearly as long as wide; terminal flagellomere invisible. Terminal labial palpomere proximally distinctly swollen and distinctly tapering towards distal acute point.

Thorax. Pronotum long and robust, nearly as long as pterothorax, bearing pedicellate, dense, long, and thick setae. Mesonotum and metanotum bearing dense, long, thick setae. Profemur bearing dense, long, soft setae, profemoral ISs rows: anteroventral row with major process arising near proximal 1/5 length of profemur and four gradually shortened processes (all processes arranged according to length) along near distal half length of profemur, primary branch very long, over 2/3 × length of protibia and 1.5 × length of secondary branch; posteroventral row with nine gradually shortened processes; primary process very long, distinctly far from and 2.5 × length of following one, slightly longer than secondary branch; protibia dorsally bearing short and dense setae, protibial prostrate setae slightly angularly curved, 25 visible; protarsus: tarsomere 1 nearly as long as tarsomeres 2–3 combined, tarsomere 2 slightly longer than tarsomere 3, slightly shorter than tarsomere 5, tarsomere 4 slightly shorter than tarsomere 3, tarsomeres 1–4 ventrally bearing 8, 3, 3, 2 conical setae respectively. Mid and hind legs bearing dense long setae; meso- and meta-tarsi each with tarsomere 1 c. as long as tarsomeres 2–5 combined, tarsomere 2 as long as tarsomeres 3–4 combined or tarsomere 5, tarsomere 3 slightly longer than tarsomere 4, tarsomeres 1–4 distally bearing 4, 6, 7, 12 pairs of thickened setae respectively; two simple pretarsal claws; arolium sac-like, with rounded apex.

Wing poorly preserved, branches of CuA and CuP with dense apical twigging. Forewing with dark markings on scp-ra and posterior margin; A3, a large dark stripe extending from 2 m-cu to posterior margin; trichosors absent on wing base; costal space moderately broad; ScA absent; recurrent humeral vein simple; 10 (left) or 16 (right) costal crossveins visible, largely bifurcated and trifurcated; subcostal space with one crossvein distinctly distal to original point of RP; one ra-rp visible; RP with three main branches visible; proximal r-m present; 1rp-m upright, slightly distal to primary branching point of M; M diverging from R proximal to lm-cu for a short distance; 1 m-cu distinctly distal to Cu branching point, 2 m-cu distinctly distal to cua-cup; CuA pectinately branched near its median, with at least six main branches; CuP dichotomously branched at its proximal 1/3; A1 with two main branches, each simple or forked; A2 bifurcated or trifurcated; A3 simple.

Hind wing similar to forewing, but immaculate; costal space very narrow, directly extending to pterostigma, with four or nine simple crossveins visible; pterostigma distinct, incorporated veinlets distinct; subcostal space veinless; original point of RP closer to wing base, with eight branches visible; five outer gradates visible; 1rp-m upright, distinctly proximal to MP branching point; im cell with three main branches; CuA pectinately branched, long, with 11 main branches, all bifurcated or trifurcated; CuP reduced, proximally very weak, with three simple branches; cua-cup very short or absent; A1 distally bifurcated; A2 simple.

Terminalia bearing dense, long, soft setae. Tergum 9 separate from ectoprocts, c. 2/3 × length of latter; sternum 9 broad, large, very shallow, tapering posteriorly into an obtuse process, surpassing apex of ectoprocts slightly, c. 4.0 × length of latter; gonocoxite 10 invisible; gonapophyses 10 very broad; gonostyli 10 (pseudopenis) very long, coiled dorsad; ectoprocts long elliptical, wider than long; callus cerci invisible; gonocoxites 11 (gonarcus) posteriorly very broad and incised with two acute processes.

Female unknown.

Material examined Holotype, BXAM BA-NEU-005 , amber piece preserving a complete male adult of D. zhangwenjuni sp. nov., polished in the form of a subrectangular transparent cabochon, with length × width c. 26.60 × 15.75 mm, height c. 7.88 mm.

Etymology The new species is dedicated to Mr. Wenjun Zhang, the family member of the first author, Mr. De Zhuo.

Remarks As mentioned above in D. arcimaculata sp. nov., D. zhangwenjuni sp. nov. is similar to D. arcimaculata sp. nov., D. longa and D. pubescens in the profemoral posteroventral row with the primary process distinctly far from the following one. However, this new species can be distinguished from the latter three species by the major process with the primary branch 1.5 × length of the secondary branch and the protibial prostrate setae slightly angularly curved. Furthermore, the new species differs from D. longa by the primary process of the profemoral posteroventral row slightly longer than the secondary branch of the major process and the male gonostyli 10 very long and coiled. It differs from D. pubescens by the macular forewing with costal crossveins dense, mostly bifurcated or trifurcated proximal to the level of proximal ra-rp. Lastly, this new species can be distinguished from D. zhangzhiqiae sp. nov. by the protibial prostrate setae slightly angularly curved, the male gonostyli 10 very long and coiled and the male gonocoxites 11 posterodorsally without any spinuous setae. For the comparison between D. zhangwenjuni sp. nov. and D. arcimaculata sp. nov. see Remarks under the latter species.
