Abdosetae hainan Fu et al., 2010: 86, fig 1–11 (♂ ♀).
Material examined. Type material: male (holotype) and one female (paratype), China, Hainan Province, Lingshui County, Mt. Diaoluo (18.87°N, 109.83°E), 6 June 2009, leg. Chao Zhang and Guangxin Han (deposited in MHBU, examined).
Other material examined. China, Hainan Province: 3♀ 2♂, Lingshui County, Mt. Diaoluo (18°40′13″N, 109°53′44″E), 250 m a.s.l., 29 January 2015, leg. Chi Jin (MHBU); 1♀ 1♂, Lingshui County, Mt. Diaoluo (18°41′23″N, 109°52′18″E), 274 m a.s.l., 27 January 2015, leg. Chi Jin (MHBU).
Diagnosis. This species can be easily distinguished from other Chinese species by lacking a RTA branch, the more distal palpal ventral tibial hump, the epigyne that lacks concavities, and the copulatory openings that are visible. The species can be distinguished from A. ornata by the following characters: 1) the embolus is relatively longer; 2) the DTA has a hooked tip and is more slender; 3) the TA is inconspicuous and hump-shaped, whereas it is conspicuous and spine-shaped in A. ornata; 4) the spermathecae are kidney-shaped and close together, whereas they are spherical and separated by almost one spermatheca’s diameter in A. ornata.
Description. Male. Total length 1.93–2.06 (n=4). Holotype (Fig. 1 A): total length 1.95; carapace 0.97 long, 0.84 wide; abdomen 0.81 long, 0.59 wide. Carapace elongate-ovoid in dorsal view, abruptly narrowing anteriorly, thoracic part slightly higher than cephalic part, highest nearly at fovea, widest at coxae II and III; pale brown at centre, dark grey at periphery, cephalic groove and radial furrow brown; fovea distinct, short, longitudinal. In dorsal view, AER slightly recurved, PER slightly wider than AER and recurved; eye diameters: AME 0.09, ALE 0.08, PME 0.07, PLE 0.08; eye interdistances: AME–AME 0.02, AME–ALE 0.01, PME–PME 0.08, PME–PLE 0.03, ALE–PLE 0.06; MOA 0.18 long, front width 0.18, back width 0.22. Clypeus height 0.09. Leg measurements: I 3.72 (0.96 + 0.35 + 1.03 + 0.91 + 0.47), II 3.06 (0.82 + 0.35 + 0.73 + 0.73 + 0.43), III 2.92 (0.78 + 0.30 + 0.60 + 0.75 + 0.49), IV 4.24 (1.09 + 0.37 + 0.97 + 1.16 + 0.65). Leg spination: see Table 1.
Abdomen ovoid, light grey; posterior half dark with several indistinct chevrons dorsally; flanks dark grey (Fig. 1 A).
Palp (Figs 1 G–I). Femur distally weakly swollen ventrally. Tibia with one thick RTA, one slender DTA and one conspicuous VTH. RTA wide basally, abruptly narrowing, with slender tip; humped retrolaterally, with ventral humps on prolateral side medially. DTA with hooked tip, bending towards cymbium. Cymbium with RBC that is visible in ventral and dorsal views. Tegulum convex, tegular apophysis inconspicuous, hump-shaped. Embolus spine-shaped, relatively short, situated at tip of tegulum, pointed towards 1 o’clock position.

Abdomen dorsally without scutum, with longitudinal black stripe. Body darker than in male; other characters as in male.
Epigyne (Figs 1 E–F). Without concavities, flat, copulatory openings situated centrally, round and visible; copulatory ducts relatively short, connected to two large, oval transparent bursae that have an oval, sclerotized base; spermathecae small and kidney-shaped, close together, located proximally; longitudinal distance between copulatory openings and spermathecae is almost one spermatheca’s length; bursae and spermathecae connected by slender tube.
Distribution. Known from three localities in south-western Hainan (Fig. 8).
