Khorata luojinensis View in CoL sp. nov.
Figs 25–28, 61
Type material: Holotype: male ( IZCAS), Miaomenshan Cave [24°58.206ʹN, 110°08.356ʹE, alt. 273 m], Daxi Village , Luojin Town , Yongfu County, Guilin, Guangxi, China, 21 July 2009, Z.Y. Yao and C.X. Wang leg. GoogleMaps
Paratypes: 10 males, 10 females ( IZCAS), same data as holotype GoogleMaps ; 2 females ( IZCAS), Linggong Cave [24°58.415ʹN, 110°08.214ʹE, alt. 251 m], other data as holotype GoogleMaps .
Etymology: The specific name refers to the type locality; adjective.
Diagnosis: This species is very similar to K. paquini sp. nov. in having similar narrow dark median line behind ocular area (Figs 25C, 26C, 41C, 42C) and similar shape of procursus (Figs 25A–B, D; 27A, D; 28A;
41A–B, D; 43A, D; 44A), but can be distinguished by the shape of apophyses of male chelicerae (Figs 27B– C), the ventral view of female genital area (Figs 26A, 28B), and the long pore plates of epigynum (Figs 26B, 28C). This species also resembles K. triangula sp. nov. in having similar narrow dark median line behind ocular area (Figs 25C, 26C, 55C, 56C), similar shape of male chelicerae (Figs 27B–C, 57B–C), and similar ventral view of female genital area (Figs 26A, 28B, 56A, 58B), but can be easily distinguished by the different distal elements of procursus (Figs 25A–B, D; 27A, D; 28A) and the long pore plates of epigynum (Figs 26B, 28C).
Description: Male (holotype): Total length 2.28 (2.36 with clypeus), prosoma 0.81 long, 1.01 wide, opisthosoma 1.47 long, 1.16 wide. Leg I: 21.67 (5.26 + 0.45 + 5.51 + 7.82 + 2.63), leg II: 14.04 (3.91 + 0.38 + 3.53 + 4.81 + 1.41), leg III: 10.68 (3.14 + 0.35 + 2.63 + 3.53 + 1.03), leg IV: 13.45 (4.04 + 0.37 + 3.40 + 4.55 + 1.09); tibia I L/d: 45. Habitus as in Fig. 25C. Dorsal shield of prosoma yellowish, with black margins and narrow dark median line 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 0.10; diameter PME 0.12; distance PME-ALE 0.02; AME absent. Sternum slightly wider than long (0.64/0.56). Chelicerae as in Figs 27B–C, with pair of long, hooked frontal apophyses (distance between tips: 6 µm); pair of short, hooked proximal apophyses provided with lateral elliptic ledges, without modified hairs; pair of small ledges on frontolateral surface distally. Palps as in Figs 25A–B; 27A, D; trochanter with retrolateral apophysis and small ventral projection, femur with retrolateral apophysis, patella large, procursus simple proximally but complex distally, bulb simple, with embolus and small rounded hump retrolaterally. Retrolateral trichobothrium of tibia I at 13%; 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: Tibia I in other males (n=10): 5.19–5.77 (mean: 5.45).
Female: Similar to male, habitus as in Figs 26C–D. Tibia I in females (n=10, leg I lost in the other two specimens): 4.75–5.25 (mean: 4.94). Genital area brown (Figs 26A, 28B), with internal structures nearly invisible through cuticle, without distinct pockets. Dorsal view of epigynum (Figs 26B, 28C) with two long pore plates.
Distribution: The species is known from two localities in Daxi Village ( Fig. 61 View FIGURE 61 ).
