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

Coloration (Figs 28C View Figure 28 , 29C View Figure 29 ). 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 View Figure 23 ). 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 View Figure 24 , 28D View Figure 28 , 29D View Figure 29 ). 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 spination: patellae III-IV d1; tibiae II-IV r1; metatarsi III-IV p1 d2 r1.

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

Epigyne (Fig. 24A, B View Figure 24 ). 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.
