Khorata circularis View in CoL sp. nov.

Figs 28–30 View FIGURE 28 View FIGURE 29 View FIGURE 30 , 41 View FIGURE 41

Type material. Holotype: Male ( IZCAS), near the entrance of Lom Cave [18°57.458′N, 102°26.245′E, alt. 314 m], 4.01 km north of Vieng keo Village, Vang Vieng District, Vien Tiane, Laos, 2 December 2012, leg. Z. Yao (Yao-LA 080–083). Paratypes: 1 male and 2 females ( IZCAS), same data as holotype.

Etymology. The specific name is from Latin circularis (rounded), in reference to the shape of pore plates of vulva; adjective.

Diagnosis. The species resembles K. luojinensis ( Yao & Li 2010: 9, figs 25–28 and 61) and K. paquini ( Yao & Li 2010: 13, figs 41–44 and 61), but can be distinguished by different shape of proximocentral apophyses of male chelicerae ( Figs 30 View FIGURE 30 C–D), different shape of distal sclerites of procursus ( Figs 28 View FIGURE 28 A–D and 30A–B) and rounded pore plates ( Figs 29 View FIGURE 29 B and 30F).

Description. Male (holotype): Total length 2.76 (2.85 with clypeus), prosoma 0.90 long, 1.08 wide, opisthosoma 1.86 long, 1.20 wide. Leg I: 34.16 (8.27 + 0.50 + 8.21 + 13.72 + 3.46), leg II: 21.22 (6.03 + 0.50 + 5.01 + 7.69 + 1.99), leg III: 16.02 (4.85 + 0.42 + 3.73 + 5.77 + 1.25), leg IV: 19.63 (6.09 + 0.44 + 4.55 + 7.44 + 1.11); tibia I L/d: 65. Habitus as in Fig. 29 View FIGURE 29 C. Dorsal shield of prosoma yellowish, with black margins and a median dark stripe behind ocular area; sternum black. Legs yellowish, but whitish on distal parts of femora and tibiae, without darker rings. Opisthosoma grey, with large black spots. Distance PME-PME 0.17, diameter PME 0.16, distance PME-ALE 0.02, AME absent. Ocular area slightly elevated and separated from prosoma. Thoracic furrow shallow but distinct. Sternum slightly wider than long (0.81/0.70). Chelicerae as in Figs 30 View FIGURE 30 C–D, with a pair of long, hooked frontal apophyses provided with scales distally (tips close together), a pair of thumb-shaped proximal apophyses, a pair of sclerotized proximocentral apophyses provided with scales, and a pair of small distal apophyses on frontolateral surface. Pedipalpi as in Figs 28 View FIGURE 28 A–B and 30A–B; trochanter with a short retrolateral apophysis and a small ventral apophysis; femur with a retrolateral apophysis; patella large; procursus simple proximally but complex distally; bulb simple, no other apophyses except for embolus. Retrolateral trichobothrium of tibia I at 8%; most hairs lost on legs; tarsus I with about 13 distinct pseudosegments.

Variation: Unknown (leg I lost in another specimen).

Female: Similar to male, habitus as in Figs 29 View FIGURE 29 D–E. Tibia I (n=2): 7.24, 7.50 (mean: 7.37). One of the specimens measured: Total length 2.96 (3.04 with clypeus), prosoma 0.96 long, 1.08 wide, opisthosoma 2.00 long, 1.36 wide; tibia I: 7.50. Distance PME-PME 0.16, diameter PME 0.16, distance PME-ALE 0.02, AME absent. Epigynum ( Figs 29 View FIGURE 29 A and 30E) brown, without pockets. Vulva ( Figs 29 View FIGURE 29 B and 30F) with an M-shaped arch anteriorly and a pair of rounded pore plates.

Distribution. Known only from the type locality ( Fig. 41 View FIGURE 41 ).
