Types.

Holotype ♂, CHINA, Yunnan: Mengla County: Xishuangbanna Nature Reserve, Xiaolongha biodiversity preservation corridor, 21°24.265'N, 101°37.296'E, elevation ca 653 m, 27.06.2012, valley evergreen rain forest, sieving. Paratypes 1♂2♀, same data as holotype.

Etymology.

This species’s name is derived from the Chinese Pinyin 'xiǎo lóng hā’, which is the type locality of this species; term in apposition.

Diagnosis.

This species is distinguished by the shape of convector in male (Fig. 45B; Tanasevitch 2006b: figs 45-46) and the loops of copulatory ducts in female’s epigyne (Fig. 46C; Song and Li 2008: fig. 287), but differs from the type species by the inconspicuous dorsal tibial apophysis (Fig. 45A) and ridges on convector in male’s palp (Fig. 44 A–B), and three more loops than the copulatory ducts make in female’s epigyne.

Description.

Male (holotype). Total length: 1.40. Carapace 0.63 long, 0.58 wide, yellow. Sternum 0.39 long, 0.56 wide. Clypeus 0.17 high. Chelicerae promargin with 3 teeth, retromargin with 3 teeth. Eye sizes and interdistances: AME 0.05, ALE 0.06, PME 0.08, PLE 0.08, AME-AME/AME 0.56, PME-PME/PME 0.60, AME-ALE/ALE 0.33, PME-PLE/PLE 0.50, coxae IV separated by 2.00 times their width. Length of legs: I 2.34 (0.63, 0.22, 0.58, 0.50, 0.41), II 2.33 (0.63, 0.20, 0.58, 0.53, 0.39), III 1.81 (0.50, 0.19, 0.39, 0.42, 0.31), IV 2.69 (0.63, 0.19, 0.53, 0.54, 0.35). Leg formula: I-II-IV-III. Tm I 0.63, Tm IV 0.59. Tibial spine formula: 2-2-1-1. Abdomen pale, with a black posterior end. Palp: tibia equipped with two retrolateral trichobothria, one dorsal trichobothrium, and a small dorsal apophysis (Fig. 45A). Paracymbium ‘J’ -shaped, with a bifurcate tip (Fig. 44B). Tailpiece tongue-shaped when viewed dorsally (Fig. 44D). Convector prominent, comma-shaped, covering most part of the embolic division (Fig. 45B). Embolus thread-like, coiled, stretching along the outer margin of distal suprategular apophysis (Fig. 44B).

Female (one of paratypes). Total length: 1.60. Carapace 0.60 long, 0.56 wide, unmodified, same as male in coloration. Sternum 0.32 long, 0.40 wide. Clypeus 0.16 high. Chelicerae promargin with 6 teeth, retromargin with 3 teeth. Eye sizes and interdistances: AME 0.05, ALE 0.08, PME 0.06, PLE 0.07, AME-AME/AME 0.63, PME-PME/PME 0.52, AME-ALE/ALE 0.23, PME-PLE/PLE 0.38, coxae IV separated by 2.00 times their width. Length of legs: I 2.32 (0.63, 0.20, 0.58, 0.50, 0.41), II 2.34 (0.64, 0.20, 0.57, 0.55, 0.38), III 1.80 (0.50, 0.18, 0.38, 0.43, 0.31), IV 2.36 (0.63, 0.23, 0.61, 0.55, 0.33). Leg formula: IV-II-I-III. Tm I 0.71, Tm IV 0.68. Tibial spine formula: 2-2-1-1. Abdomen light pink, with a black tip. Epigyne: ventral fig semi-transparent, mesally concave at the posterior rim (Fig. 46A); copulatory ducts long, forming about five loops before joining spermathecae (Fig. 46C); spermathecae oval, separated by 1.5 times their diameter (Fig. 46B).
