Holotype. ♂, China, Yunnan Province, Dehong Dai and Jingpo Autonomous Prefecture, Gaoligongshan Nature Park, 24.8°N, 98.8°E, Alt. 2000 m, 4-Ⅴ-2022, coll. Michael Zelun Lee, Yejie Lin, Tongyao Jiang & Zhitao Zhang.
Paratypes. 1♂ 2♀, same data as in holotype.
Description. Body size small. Head and thorax. Ocelli oval (Fig. 1A). Fastigium of vertex as wide as the first antennal segment, without longitudinal furrow above (Fig. 1D). Occiput with a slightly twisting longitudinal median suture (Fig. 1 BD). Anterior and posterior margins of pronotum convex (Fig. 1 BD). Lateral lobes longer than deep, ventral margin oblique (Fig. 1D). Disc of pronotum arc-shaped in front view. Prosternum with a pair of processes, apical area pointed; basal half of mesosternum wide, the lateral margins constricted about middle areas, then terminating into a pair of stout spines; metasternum with a pair of triangular processes, internal margins nearly straight, external margins slightly expanded, apices obtuse (Fig. 1C). Wings absent (Fig. 1 BD).
Legs. Fore and mid coxae with a spine (Fig. 1D). Genicular lobes of all femora without spines (Figs. 2, 3). External surface of hind femur with distinct chevron ridges (Fig. 3). Tympana elongated oval on both sides of fore tibiae (Fig. 2 AB). All femora without spinules. Fore tibia dorsally with 1 internal spine and 1 pair of apical spurs; ventrally with 4 pairs of moveable spines and 1 pair of apical spurs, with the internal spurs of both pairs being longer (Fig. 2 AB). Mid tibia dorsally with 3 internal spines, 2 external spines and 1 pair of apical spurs; ventrally with 4 pairs of spines, and 1 pair of apical spurs (Fig. 2 CD). Hind tibia dorsally with 9~10 internal, 9~10 external spines and 1 pair of elongated apical spines; ventrally with 1 pair of short spines, and 3 pairs of apical spurs gradually increasing in length and size towards tip (Fig. 3).
Male. Posterior area of tenth abdominal tergite with a pair of upcurved hooks, located right below the pair of semi-circular lateral processes on the posterior margin of ninth abdominal tergite (Fig. 4 AD). Each paraproct with an elongated and upcurved process (Fig. 4 ABD). Epiproct hidden under the pair of paraprocts (Fig. 4A). Cerci cylindrical, gradually narrowing towards apex, apices obtuse, longer than length of paraproct (Fig. 4 ABD). Basal area of subgenital plate broad, apical area rectangular, with a pair of lateral carinae (Fig. 4C). Posterior margin of subgenital plate straight, with a pair of cylindrical styli laterally (Fig. 4C).
Female. Ovipositor upcurved, gradually tapering towards the apex, basal area stout, dorsal valvulae longer than ventral ones (Fig. 4F). Cerci conical, apices acute (Fig. 4F). Subgenital plate roughly triangular, basal area broad, triangularly narrowing posteriorly, lateral margins distinctly constricted at transition between basal and apical areas, apex acute (Fig. 4E).
Coloration. Body generally dark reddish-brown. Occiput with a grey patch. Pronotum with an hourglass-shaped white marking. Abdominal tergite with irregular yellowish spots.
Measurements (mm). Body length: ♂ 13.9~14.2, ♀ 13.3~14.8; length of pronotum: ♂ 4.7~4.8, ♀ 4.9~5.0; length of fore femur: ♂ 5.3~5.6, ♀ 6.2~6.4; length of mid femur: ♂ 5.5~5.8, ♀ 6.7~7.0; length of hind femur: ♂ 15.4~15.8, ♀ 16.8~17.2; length of fore tibia: ♂ 6.2~6.4, ♀ 7.4~7.5; length of mid tibia: ♂ 6.8~7.0, ♀ 7.7~8.0; length of hind tibia: ♂ 13.3~13.6, ♀ 15.4~15.6; length of ovipositor: 12.3~12.5.
Remarks. Anabropsi s (Spinanabropsis) zeluni is unique, it differs from all apterous species of Anabropsis by the enlarged hourglass-shaped white band on pronotum (Fig. 5, 6).
Etymology. This species is named after the collector Michael Zelun Lee (University of California, Riverside).
Distribution. Yunnan (China).
