Figures 1–7
Description. Male. Body medium. Fastigium verticis projecting forward, dorsal surface with an indistinct longitudinal carina along the midline (Fig. 1A). Ocelli distinct, median ocellus oval, slightly longer than wide; lateral ocelli oval, suited on the lateral margins of fastigium verticis. Eyes projecting outwards. Apical segments of maxillary palpi longer than subapical ones, apices slightly swollen (Fig. 1C). Anterior margin of pronotal disc almost straight, posterior margin widely rounded, before the posterior margin with fine longitudinal riffles (Fig. 1B); lateral lobes longer than deep, humeral sinus shallow. Prosternal lobes spine-shaped, basal area moderately wide, apices subacute; internal margins of mesosternal lobes straight, sub-basal areas of external margins contract narrowing to apices, apices obtuse; metasternal lobes long digitate, basal area separated from each other, internal margins almost straight, external margins obviously convex, then gradually passing into sub-cylindrical, apical area with obtuse apices (Fig. 1C). Fore and middle coxae swollen, with 1 depressed spine respectively. Fore femora with 2–4 internal spines on ventral surface; tibiae with 1 external and 2 internal spines on dorsal surface, ventrally with 5 pairs of spines, including 1 pair of apical spines; basal area of tibiae with oval, opened tympana on both sides, the internal one larger than external one (Fig. 2A–B). Middle femora ventrally with 0–3 small spines on external margins, apices of genicular lobes with 1 internal spine; tibiae dorsally with 3 external and 4 internal spines, ventral surface with 5 pairs of spines. Hind femora ventrally with 3–7 external and 4–11 internal spines, apices of genicular lobes with 1 internal spine; tibiae dorsally with 9–12 external and 10–11 internal spines, ventral surface with 2–3 external spines and 0–1 internal spine, subapical areas with 1 pair of ventral spines, apices with 1 pair of dorsal and 2 pairs of ventral spines.
Abdomen. Posterior margin of ninth abdominal tergite arched concave, lateral margin with 1 pair of subtriangular processes (Fig. 1E); posterior margin of tenth abdominal tergite almost straight, lateral areas with a pair of up-curved hooks inserted just laterally of the processes of ninth abdominal tergite (Figs. 1E, 2D, 3E). Paraproctal processes shorter than cerci, upcurved, basal areas stout, narrowing to basal two fifths; dorsal and ventral margins of middle areas nearly parallel (Fig. 3I); apices with a subtriangular process, the hind margins obliquely, and slightly concave in lateral view, ventral angles widely rounded (Fig. 3I). Cerci slender, apices acute. Subgenital plate slightly shorter than one half of cerci (Fig. 2C); basal half broad, the lateral margins obviously convex, then contracted about middle area, ventral surface with 1 pair of parallel longitudinal carinae; anterior margin ached, posterior margin with obtusely triangular concave (Figs. 2C, 3I). Styli cylindrical, inserted the apico-lateral margins (Fig. 2C). Phallus membranous (Fig. 2E–F).
Female. Cerci conical, apices subacute. Subgenital plate longer than wide, basal area triangular, about 1.4–1.6 times as long as apical spine (Fig. 5G). Ovipositor curved dorsad, basal area stout, narrowing to apices, dorsal valvulae longer than ventral ones, apices of dorsal valvulae narrowly rounded, apices of ventral valvulae acute (Fig. 5K).
Wings. Reaching or slightly surpassing the apex of abdomen, but not reaching the apices of hind femora (Figs. 3L, 5K, 7). Venation: radius with radius sector branching in about apical third of tegmen, RS with additional branches about subapical area (Figs. 4B, E; 6C, F). Media not fused in basal area with radius and divided into two veins between basal third and middle of tegmen on both tegmina. The right tegmen of one male has the media posterior divided after mid-length of tegmen into two branches, the posterior branch makes a curvature and fuses for a short distance with CuA, shortly after it divided again (Fig. 4E). Cubitus anterior forks into two veins near end of basal third (Figs. 4B, 6C, F), the anterior vein of male left tegmen forked again (Fig. 4B), while in female left tegmen CuA has a common stem with media (Fig. 6C). Cubitus posterior free and undivided, with 4 anal veins (all specimens, Figs. 4B, E, 6C, F).
Coloration. Body black brown with fine and irregular light spots. Ocelli pale yellow. Pronotum dark brown with light flecks. Legs largely black with yellowish or whitish genicular areas, dorsal surfaces of fore and middle tibiae lighter. Tegmen semi-transparent, brown or blackish-brown with black spots.
Measurements (mm). Male: BL 30.9–31.0, PL 7.3–8.1, TL 19.8–24.5, HFL 26.2–26.5; Female: BL 25.8–33.8, PL 7.2–8.2, TL 19.6–23.9, HFL 25.2–28.1, OvL 16.1–19.8.
Material examined. Holotype: male, Gulinjing, Maguan, Yunnan, July 28, 2021, coll. by Xun Bian, Wei Bin and Xiaoyu Peng; Paratypes: 4 females, the other information as holotype. Other specimens: 1 male and 1 female, Gulinjing, Maguan, Yunnan, July 28, 2021, Xiangjin Liu; 1 female, the other information as holotype.
Distribution. Yunnan (Cangyuan).
Discussion. The new species is very similar to Anabropsis (Pteranabropsis) angusta (Ingrisch, 2019), Anabropsis (Pteranabropsis) bavi (Ingrisch, 2019), Anabropsis (Pteranabropsis) cuspis, (Ingrisch, 2019) and Anabropsis tibetensis (Wang, Liu & Li, 2015), but differs from them in: wings reaching or slightly surpassing the apex of abdomen (Figs. 3I, 5K); metasternal lobes with 1 pair of digitiform processes, the internal margins concave and external margins convex at basal areas (Figs. 1C, 3D, 5E), then gradually passing into sub-cylindrical, apices obtuse; dorsal margins of male paraproctal processes with subacute tip, the hind margins obliquely, and slightly concave in lateral view, ventral margin widely rounded (Fig. 3I); and lateral margins of female subgenital plate without distinct constriction from the wider basal to the narrow apical area (Fig. 5G). For Anabropsis tibetensis (Wang, Liu & Li, 2015), wings extending the apices of hind femora (Wang et al., 2015: Fig. D) and metasternal lobes triangular with pointed apices (Wang et al., 2015: Fig. 20). Anabropsis (Pteranabropsis) bavi (Ingrisch, 2019) possesses the wings not or just reaching apices of hind femora (Ingrisch, 2019: Fig. 1G), and female subgenital plate with distinct constriction at lateral margins from wider basal to the narrow apical area (Ingrisch, 2019: Fig. 5G). In Anabropsis (Pteranabropsis) angusta (Ingrisch, 2019), wings are justly reaching the apices of hind femora (Ingrisch, 2019: Fig. 1F) and the apical areas of male paraproctal processes has slightly widening dorsal area with a small, dorso-ventrally compressed tip, and the ventral surface processes widely rounded (Ingrisch, 2019: Fig. 3J–N). While Anabropsis (Pteranabropsis) cuspis, (Ingrisch, 2019), wings are not reaching the apices of hind femora (Ingrisch, 2019: Fig. 1B) and the apical areas of male paraproctal processes have a large, acute-triangular dorsal spine, the hind margins slightly concave in lateral view, ventral angles narrowly rounded (Ingrisch, 2019: Fig. 3E–I).
Etymology. Named after the type locality.
