Diagnosis Pronotum short and robust (LP: WPM = 2.70), nearly as long as pterothorax. Protibia dorsally bearing short setae, protibial prostrate setae strongly angularly curved setae. Forewing with a dark stripe on posteroproximal portion (formed by markings on 2 m-cu, cua-cup, and between CuP and A1), extending from 2 m-cu to margin, 18 costal crossveins proximad pterostigma, near 1/3 of them bifurcated or trifurcated, two ra-rp, CuA with three main branches; hind wing medial inner gradates absent. Male sternum 9 broad and large, very shallowly scoop-like, surpassing apex of ectoprocts slightly, 2.0 × length of latter; gonocoxites 9 distally bifurcated; gonapophyses 10 broad; gonostyli 10 (pseudopenis) short, curved dorsad; ectoprocts short, oval, wider than long; gonocoxites 11 (gonarcus) dorsoposteriorly with four curved anteriad, thick, spinuous setae.

Description Measurements and proportions. Male. Body length 8.48; LP (1.65): WPM (0.61) = 2.70; LFW (7.54): WFW (2.13) = 3.54; LFPt (1.30): WFPt (0.30) = 4.33; LF2r (1.42): WF2r (0.21) = 6.76; LFim (1.89): WFim (0.24) = 7.88; LHW (6.49): WHW (2.04) = 3.18; LHPt (1.46): WHPt (0.26) = 5.62; LHim (1.73): WHim (0.18) = 9.61.

Morphology. Male. Head setae lost. Vertex slightly domed; epicranial suture present. Postocular region narrow in lateral view. Antenna reaching pronotal posterior end; scape robust, distally strongly swollen, nearly 1.5 times as long as wide, nearly twice as long as pedicel; pedicel swollen, nearly as long as wide, slightly longer than flagellomere 1; flagellum 29-segmented; each flagellomere nearly as long as wide; terminal flagellomere tapering distally, nearly twice as long as prior one.

Thorax. Pronotum short and robust, nearly as long as pterothorax, most long thick setae lost due to the state of preservation, pedicellate bases dense. Foreleg destroyed badly; protibia dorsally bearing dense, short setae; protibial prostrate setae strongly angularly curved, eight visible; protarsus: tarsomere 1 slightly longer than tarsomere 2, and slightly shorter than tarsomere 5, tarsomeres 2–4 subequal. Mid and hind legs bearing dense long setae, distally destroyed or too obscure to be described.

Wing long elliptical, branches of RP, M, CuA, and CuP with dense apical twigging. Forewing with small dark markings on ra-rp, outer gradates, 2 m-cu, cua-cup, outer and posterior margins, a distinct dark stripe (formed by markings on 2 m-cu, cua-cup, and between CuP and A1), extending from 2 m-cu to margin; trichosors absent on margin of wing base; costal space moderate broad, directly extending to pterostigma; ScA absent; recurrent humeral vein simple or bifurcated; 18 costal crossveins proximad pterostigma, 1/3 of them bifurcated or trifurcated; pterostigma distinct, commencing slightly distal to 2ra-rp, extending to 3/4 length of 3r cell, with distal margin sinuous and moderately oblique; incorporated veinlets obscure; subcostal space distally slightly broadened proximad pterostigma, with only one crossvein distinctly distal to origin of RP; two ra-rp, proximal ra-rp (1ra-rp of the species with three ra-rp on forewing) absent; 2r cell with one RA branch running to costal margin; RP originating near proximal 1/4 length of wing, with five main branches proximally smooth; three outer gradates; 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; im cell with four main branches; 1 m-cu distinctly distal to Cu branching point, 2 m-cu distinctly distal to cua-cup; CuA nearly pectinately branched near its median, with three main branches; CuP nearly pectinately branched slightly proximal to its median, with three main branches; A1 trifurcated distally; A2 bifurcated distally; A3 simple.

Hind wing similar to forewing, but immaculate; costal space very narrow, with 21 simple crossveins visible along its entire length; pterostigma longer; subcostal space slightly narrower, veinless; three (right) or possibly two (left) ra-rp, proximal ra-rp (1ra-rp of the species with three ra-rp on hind wing) possibly absent on left; original point of RP closer to wing base, with five branches; four outer gradates; 1rp-m upright, slightly or distinctly proximal to primary branching point of M; im cell with two or three main branches; CuA pectinately branched, long, with eight or nine main branches, most distally bifurcated; CuP reduced, proximally weak, with two simple branches; A1 distally bifurcated.

Terminalia bearing dense, long setae. Tergum 9 distinctly shorter than tergum 8, separate from ectoprocts; sternum 9 broad and large, very shallowly scoop-like, surpassing apex of ectoprocts slightly, c. 2.0 × as long as latter; gonocoxites 9 stout, distally bifurcated, scleritized strongly; gonocoxites 10 invisible; gonapophyses 10 broad; gonostyli 10 (pseudopenis) short, curved dorsad; ectoprocts short, oval, wider than long; callus cerci present; gonocoxites 11 (gonarcus) posterodorsally with four curved anteriad, thick, spinuous setae.

Female unknown.

Material examined Holotype, BXAM BA-NEU-006 , amber piece preserving a complete male adult of D. zhangzhiqiae sp. nov., polished in the form of a long elliptical transparent cabochon, with length × width c. 17.44 × 13.63 mm, height c. 8.57 mm.

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

Remarks Doratomantispa zhangzhiqiae sp. nov. resembles D. zhangwenjuni sp. nov. by having the distinct stripe on the posteroproximal portion of forewing, the absence of hind wing medial inner gradates, and sternum 9 slightly surpassing the apex of the short, oval ectoprocts (all these characters combined can separate these two species from the remaining members of Doratomantispa except D. zhuozhengmingi sp. nov. and D. longa ) (see Remarks under D. zhangwenjuni sp. nov. for morphological comparisons). This new species can be distinguished from D. zhuozhengmingi sp. nov. by the forewing with only two ra-rp, the absence of forewing inner gradates, the male gonocoxites 9 distally bifurcated, and the male gonapophyses 10 broad. The difference between D. zhangzhiqiae sp. nov. and D. longa can be found in the Remarks under the latter species.
