Type material.

Holotype: ♂ (IZCAS-Ar44698), China, Guangxi: Guilin City, Rongshui County, Taoyuan Cave, 25.0579°N, 109.2246°E, ca 131 m, 23.VII.2009, C. Wang leg. Paratypes: 3♂ 4♀ (IZCAS-Ar44699-Ar44705), same data as holotype.

Diagnosis.

The male of Typhlohnia rongshui sp. nov. can be distinguished from T. sondoong sp. nov. by the patella with apophysis retrolaterally (Fig. 23B) [vs retrodorsally (Fig. 25B)], retrolateral tibial apophysis point retrolaterally (Fig. 23B) [vs point dorsally (Fig. 25B)], conductor slender and triangle-shaped (Fig. 23A) [vs oval (Fig. 25A)], medium of sperm duct U-shaped (Fig. 23A) [vs upturned U-shaped (Fig. 25A)], embolus originating at 3:00 o’clock position (Fig. 23A) [vs 7:30 o’clock position (Fig. 25A)] and length of embolus almost 3/4 perimeter of bulb (Fig. 23A) [vs half perimeter of bulb (Fig. 25A)]. Females can be distinguished from T. suiyang sp. nov. by the unobvious glandular appendages (Fig. 24B) [vs obvious (Fig. 27B)], ratio of length to width of epigynal plate ~ 2:3 (Fig. 24A) [vs 1:1 (Fig. 27A)] and ratio of width between primary spermathecae to secondary spermathecae ~ 1:1 (Fig. 24B) [vs 2:1 (Fig. 27B)].

Leg spination: femur I p1; patellae III-IV d1; tibiae III-IV p1 d1; metatarsi III p1 d2, IV d2.

Coloration (Figs 28C, 29C). Carapace pale yellow, with a few long brown hairs. Fovea longitudinal, reddish-brown. Two eyes, white. Chelicerae, labium, and gnathocoxae pale yellow, with long brown hairs; sternum pale yellowish. Legs white. Opisthosoma oval, pale yellow. Spinnerets white.

Palp (Fig. 23A, B). Patella with apophysis retrolaterally, tip hook-shaped. Tibia with black, serrated retrolateral apophysis, little curved, point retrolaterally. Cymbium 1.5 × longer than wide, 3 × longer than cymbial furrow. Cymbial furrow shallowed. Bulb globular. Conductor sickle-shaped, almost half length of bulb. Middle of sperm duct bent in U-shape. Embolus slender and whip-shaped, almost 3/4 perimeter of bulb. Base of embolus arising at 3:00 o’clock position.

Female (paratype IZCAS-Ar44705; Figs 24A, B, 28D, 29D). Total body length 1.34. Carapace 0.59 long, 0.47 wide; opisthosoma 0.75 long, 0.48 wide. Eye size and interdistance: PLE 0.03; PLE-PLE 0.09. Clypeus 0.06 high. Chelicerae with two promarginal and three retromarginal teeth. Leg measurements: I 1.84 (0.56, 0.20, 0.41, 0.35, 0.32); II 1.76 (0.54, 0.19, 0.38, 0.34, 0.31); III 1.64 (0.49, 0.17, 0.35, 0.33, 0.30); IV 2.07 (0.59, 0.20, 0.46, 0.45, 0.37). Leg spination: patellae III-IV d1; tibiae II-IV r1; metatarsi III-IV p1 d2 r1.

Coloration (Figs 28D, 29D). As in male.

Epigyne (Fig. 24A, B). Epigynal plate 1.5 × wider than long. Depression obvious, ends with copulatory openings. Copulatory openings arc-shaped. Copulatory ducts long and strongly convoluted with one turn, medium bifurcate. The short one connected to the secondary spermathecae, the other connected to the primary spermathecae. Secondary spermathecae globular, as wide as bean-shaped primary spermathecae. Fertilization ducts directed at 9:00 o’clock position from spermathecae.

Variation.

Males (n = 2): total body length 1.38-1.46, carapace 0.68-0.71 long, 0.51-0.59 wide, opisthosoma 0.70-0.75 long, 0.55-0.57 wide. Females (n = 3): total body length 1.30-1.40, carapace 0.55-0.61 long, 0.44-0.46 wide, opisthosoma 0.73-0.81 long, 0.50-0.57 wide.
