Khorata guiensis sp. nov.

Figs 17–20, 61

Type material: Holotype: male ( IZCAS), Cave without a name [24°21.912ʹN, 111°30.952ʹE, alt. 118 m], Limu Village , Etang Town, Hezhou, Guangxi, China, 24 August 2009, Z.Y. Yao and C.X. Wang leg.

Paratypes: 3 females ( IZCAS), same data as holotype .

Etymology: The specific name refers to the type locality; adjective. Gui is the short name for Guangxi.

Diagnosis: This species can be easily distinguished from all known congeners by the different distal elements of procursus (Figs 17A–B, D; 19A, D; 20A) and the shape of pore plates of epigynum (Figs 18B, 20C).

Description: Male (holotype): Total length 2.18 (2.31 with clypeus), prosoma 0.77 long, 0.94 wide, opisthosoma 1.41 long, 1.09 wide. Leg I: 19.89 (5.01 + 0.45 + 5.06 + 7.13 + 2.24), leg II: 13.18 (3.78 + 0.42 + 3.14 + 4.49 + 1.35), leg III: 9.93 (2.95 + 0.38 + 2.31 + 3.33 + 0.96), leg IV: 12.71 (3.72 + 0.41 + 3.08 + 4.47 + 1.03); tibia I L/d: 46. Habitus as in Fig. 17C. Dorsal shield of prosoma yellowish, with black margins and black median stripe behind ocular area; sternum black. Legs yellowish, with slightly darker rings on femora (subdistally) and tibiae (proximally and subdistally). Opisthosoma grey with large black spots dorsally and ventrally. Ocular area slightly elevated and separated from prosoma, thoracic furrow shallow but distinct; distance PME-PME 0.07; diameter PME 0.08; distance PME-ALE 0.02; AME absent. Sternum slightly wider than long (0.60/0.51). Chelicerae as in Figs 19B–C, with pair of long, hooked frontal apophyses (distance between tips: 0.06); pair of strong proximal apophyses and sclerotized angular apophyses proximocentrally, respectively, without modified hairs; pair of small ledges on frontolateral surface distally. Palps as in Figs 17A–B; 19A, D; trochanter with retrolateral apophysis and small ventral projection, femur with retrolateral apophysis, patella large, procursus simple proximally but complex distally, bulb simple, no other projections except for embolus. Retrolateral trichobothrium of tibia I at 12%; legs with short vertical hairs on all metatarsi (mostly dorsally and laterally), without spines and curved hairs; tarsus I with more than 30 pseudosegments, only about 17 distinct ones distally.

Variation: Unknown.

Female: Similar to male, habitus as in Figs 18C–D. Tibia I in females (n=3): 4.49–5.26 (mean: 4.81).

Genital area brown (Figs 18A, 20B), with internal structures nearly invisible through cuticle, without distinct pockets. Dorsal view of epigynum (Figs 18B, 20C) with two pore plates.
