Male. Body medium-sized for the genus. Head. Fastigium verticis protruding forwards, compressed laterally, about half as broad as scape, dorsal surface with a distinct longitudinal furrow in the midline. Occiput with an indistinct median carina. Ocelli conspicuous, elliptic, width about 1/2 of length ( Fig. 2A–C, H–J ). Thorax. Pronotum glabrous, without longitudinal median carina ( Fig. 2A, H ), lateral lobes longer than deep, ventral margin oblique, humeral sinus absent. Wings absent, but with indistinct wing rudiments ( Fig. 2B, I ). Prosternum with 1 pair of processes, basal area stout, apical area spiny; mesosternum with 1 pair of processes, basal area stout, apical area thin, digitiform; metasternum with 1 pair of triangular processes, internal margins nearly straight, external margins slightly expanded, apices obtuse ( Fig. 2G ). Legs. Fore coxa with 1 stout spine on anterior surface; mid coxa with a smaller spine on external surface. Fore and mid femora unarmed on ventral surfaces; hind femur with 4–5 spines on internal margin and 3 spines on external margin of ventral surface, genicular lobe with an internal spinule on apex. Fore tibia with an articulated spine near the middle of dorsal surface, 4 pairs of articulated spines on ventral surface, 1 pair of apical spurs on both dorsal and ventral surfaces separately, dorsal apical spurs longer than ventral ones, basal area with an oval, developed internal tympanum, the external one reduced. Mid tibia with 3 articulated spines on internal margin and 2 articulated spines on external margin of dorsal surface, 4 pairs of articulated spines on ventral surface, and 1 pair of apical spurs on both dorsal and ventral surfaces separately, dorsal apical spurs longer than ventral ones. Hind tibia with 12 pairs of spines on dorsal surface, 1 articulated spinule on internal margin and 2 articulated spinules on external margin of ventral surface, 1 pair of apical spurs on dorsal surface and 3 pairs of apical spurs on ventral surface, dorsal apical spurs longer than ventral ones. Abdomen. Posterior margin of ninth abdominal tergite shallowly concave, with a pair of indistinct flabellate lateral processes ( Fig. 2E ). Posterior area of tenth abdominal tergite with a pair of sclerotized hooks on lateral margins, curved inwards and upwards, separated from the processes of ninth abdominal tergite ( Fig. 2F ). Epiproct linguiform, with a median concavity. Cerci conical, directed upwards, basal area stout, apical area thin, apices obtuse. Paraproct with 1 pair of long processes, basal area stout, other area narrowing, upcurved. Basal area of subgenital plate broad, apical area rectangular, with a pair of lateral carinae, posterior margin concave, apical area of subgenital plate width about 1/2 of its length. Styli on posterior margin of subgenital plate, apices obtuse ( Fig. 2D ). FIGURE 2. Anabropsis ( Paterdecolyus ) dulongjiangensis sp. nov. : A–B , H–I . head and pronotum: A , H . dorsal view; B , I . lateral view; C , J . anterior view of head; D–F , K–L . abdominal apex: D , L . ventral view; E . dorsal view; F . lateral view; G . metasternum; K . lateral view of ovipositor. A–G . male; H–L . female. Female. Body is generally similar to that of male. Subgenital plate triangular, lateral margin nearly straight, apex acute ( Fig. 2L ). Ovipositor sclerotized, obviously upcurved, basal area stout, narrowing toward apical area, apices of dorsal valvulae acute, dorsal valvulae obviously longer than ventral ones ( Fig. 2K ). Coloration. Body brown with black spots. Scape and pedicel yellowish with dark spots on internal sides, pedicel brownish with dark brown rings. Eyes dark brown, ocelli yellowish. Occiput lateral sides dark brown. Pronotum brownish, posterior margin dark brown, with irregular pale spots, disc of pronotum with a yellowish longitudinal stripe in the middle, anterior area broad, posterior area narrow, do not extend to the posterior margin of pronotum. Posterior margins of meso-, metanotum and abdominal tergites with irregular yellowish spots. Thoracic and abdominal sternites yellow-brown. Ventral surface of male subgenital plate dark brown in the middle, lateral carinae pale brown. Female subgenital plate brown. Legs yellow with brown spots. Measurements (mm). BL: ♂ 20.5, ♀ 24.3–25.5. PL: ♂ 6.0, ♀ 6.3–6.9. HFL: ♂ 20.3, ♀ 20.0–21.8. HT: ♂ 20.6, ♀ 19.0–20.8. OvL: 8.1–9.3. Material examined. Holotype : male, Dulongjiang , Gongshan , Yunnan , 2024.VI.23 , collected by Hao Xu. Paratypes : 5 females , Dulongjiang , Gongshan , Yunnan , 2024.VI.23 , collected by Hao Xu. Disrtibution. China ( Yunnan ). Discussion. The new species is similar to Anabropsis ( Paterdecolyus ) magnimaculatus ( Bian & Shi, 2019 ) , but pronotum with an incomplete longitudinal yellow stripe on the disc, without black spots, posterior margin of male subgenital plate concave. Etymology. The new species is named for the type locality.
