Anabropsis (Apteranabropsis) nigrimaculatis Pang, Lu & Bian, 2023 (Figure 3) Anabropsis (Pseudapteranabropsis) nigrimaculatis Pang, Lu & Bian, 2023, Zootaxa, 5318(2): 260 Description. 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. Eyes hemispherical. Ocelli distinct, lateral ocelli elliptic, width about 1/2 of length, median ocellus elliptic, width about 4/5 of length (Fig. 3A–C, H–J). Thorax. Pronotum glabrous, without longitudinal carina (Fig. 3A, H), lateral lobes longer than deep, ventral margin oblique, humeral sinus absent. Wings absent, but with indistinct wing rudiments (Fig. 3B, 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 a pair of triangular processes, internal margin nearly straight, external margin slightly expanded, apices obtuse (Fig. 3G). 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 spines on internal margin and 3–4 spines on external margin of ventral surface. 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 1 pair of oval, developed tympana on both internal and external sides. 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 10 pairs of spines on dorsal surface, 1 articulated spinule on internal margin and 3 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 nearly straight, lateral margins with a pair of long processes, internal margins of the processes nearly straight, external margins convex, apical area narrow, directing backwards (Fig. 3E). Posterior area of tenth abdominal tergite with a pair of sclerotized hooks on lateral sides, upcurved, and contiguous with the processes of ninth abdominal tergite (Fig. 3F). Epiproct linguiform, with a longitudinal median concavity. Cerci conical, directed upwards, basal area stout, apical area thin, apices obtuse. Paraproct with 1 pair of long processes, separating at basal area, apical area acute, sclerotized, shorter than cerci (Fig. 3E, F). Basal half area of subgenital plate broad, apical half area nearly rectangular, with obtuse lateral carinae, posterior margin straight, width of subgenital plate about 1/2 of length. Apical area of subgenital plate with a pair of cylindrical styli on ventral margin laterally, apices obtuse (Fig. 3D). 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 yellow, lateral sides dark brown. Pronotum brown, with a pair of large black spots on disc, anterior and posterior margins dark brown with irregular yellow spots. Posterior margins of meso-, metanotum and abdominal tergites dark brown, with irregular yellowish spots. Thoracic and abdominal sternites pale brown. Ventral surface of male subgenital plate dark brown, posterior margin and lateral carinae yellow. Female subgenital plate brown. Legs yellow, with brown spots. Measurements (mm). BL: ♂ 28.0. PL: ♂ 7.9. HFL: ♂ 25.3. HT: ♂ 24.0. Material examined. 1 male and 4 females, Gulinjing, Maguan, Yunnan (type locality), 2024.VI.19, collected by Hao Xu. Disrtibution. China (Yunnan). Discussion. The species was originally described based on 3 females. In this study, the male of Anabrospsis (Pseudapteranabropsis) nigrimaculatis Pang, Lu & Bian, 2023 is described for the first time. According to Pang et al. (2023), the subgenus Anabrospsis (Pseudapteranabropsis) is bifurcated on apices of paraproctal processes in lateral view, which is obviously different from the male description provided here. Therefore, we propose transferring the species to the subgenus Anabropsis (Apteranabropsis) based on the characters that apices of male paraproctal processes unbranched in lateral view and the ventral surfaces of hind femora armed.
