Shuang Xue. Paratypes : Thirteen ♂ , three ♀ , same data as holotype ; 13 ♂ , 16 ♀ , same locality as holotype, 28 May 2018 , leg. Kai Gao. Etymology The specific epithet refers to the type locality, Minshan Mountain. Diagnosis This new species can be differentiated readily from D. magna by the following characters: (1) male genital bulb spherical (cf. long and elliptical); (2) basal branch of male paramere short, hook-shaped (cf. relatively long); and (3) main plate of female medigynium nearly rectangular distally, constricted mesally and smoothly curved basally (cf. subtriangular or constricted rapidly at base). Description H e a d: H e a d y e l l o w. Ve r t e x y e l l o w i s h. O c e l l a r triangle black. Antenna blackish brown. Rostrum yellowish, without black lateral longitudinal stripes ( Fig. 14A, B ). Thorax: Pro-, meso- and metanotum yellow, bearing several setae anteriorly and two black longitudinal stripes laterally. Pleura light yellow. Legs yellowish brown, with tarsomeres gradually darkened toward apex ( Fig. 14A, B ). Wings: Male holotype : forewing length 16.5 mm , width 4.5 mm , yellowish, apical band reduced; pterostigma band incomplete and dark brown, with reduced basal and distal branches; basal band extending from vein R s to CuP, other markings indistinct; hindwing length 15.2 mm , width 4.3 mm , similar to forewing, but with more degenerated markings ( Fig. 14A ). Female: forewing length 15.5–17.6 mm , width 4.1–4.9 mm ; hindwing length 14.1–16.4 mm , width 4.0– 4.7 mm ; similar to male in general appearance ( Fig. 14B ). Abdomen: T1–T5 yellowish, with two black lateral longitudinal stripes ( Fig. 14A, B ). Male: notal organ developed, covered with numerous black setae posteriorly ( Fig. 4L ); T6 brownish yellow, bearing a pair of digitate anal horns posteriorly ( Figs 3L , 14A ); A7 and A8 yellowish brown, elongate, constricted at basal half and dilated at distal half, but A8 much thinner than A7 distally ( Fig. 14A ). Female: abdominal segments gradually narrowed caudally ( Fig. 14B ). Male genitalia: Genital bulb brownish yellow, spherical. Epandrium gradually narrowing toward apex, with a rounded, U-shaped terminal emargination ( Fig. 14C ). Hypovalve slender, bearing long bristles along inner margin, nearly reaching apex of gonocoxite ( Figs 5L , 14D ). Gonostylus shorter than gonocoxite, with a well-developed trapezoidal basal process and a small sharp subtriangular median tooth. Parameres trifurcate: basal branch considerably short, hook-shaped; mesal and lateral branches curved inward, reaching or exceeding apex of gonocoxite. Ventral valves of aedeagus short; dorsal valves broadened and elongate, nearly reaching apex of gonocoxite ( Figs 5L , 14D , 15A, B ). Female genitalia: Subgenital plate ovoid, terminating in a ligulate process, covered with long setae caudally ( Figs 14E , 15C ). Medigynium strongly sclerotized, with main plate rectangular distally, gradually constricted mesally and rounded basally. Posterior arms parallel and short, approximately half the length of main plate ( Figs 6L, M , 14F ).
