Khorata dongkou View in CoL sp. nov.
Figs 5–8, 61
Paratypes: 10 males, 15 females ( IZCAS), same data as holotype .
Etymology: The specific name is from the Chinese words for cave (dòng) and entrance (kǒu), in reference to the entrance of Shuilong Cave; noun.
Diagnosis: This species resembles K. flabelliformis sp. nov. and K. miaoshanensis sp. nov. in having similar male chelicerae (Figs 7B–C, 15B–C, 35B–C) and similar ventral view of female genital area (Figs 6A, 8C, 14A, 16C, 34A, 36C), but can be distinguished by the different distal elements of procursus (Figs 5A–B, D; 7A, D; 8A) and the nearly elliptic pore plates of epigynum (Figs 6B, 8B). This species also resembles K. wangae sp. nov. in having similar ventral view of female genital area (Figs 6A, 8C, 59A, 60A), but can be distinguished by the shape of pore plates of epigynum (Figs 6B, 8B).
Description: Male (holotype): Total length 2.05 (2.21 with clypeus), prosoma 0.75 long, 0.87 wide, opisthosoma 1.30 long, 0.98 wide. Leg I: 18.61 (4.68 + 0.45 + 4.74 + 6.50 + 2.24), leg II: 12.28 (3.46 + 0.42 + 3.08 + 4.10 + 1.22), leg III: 9.14 (2.63 + 0.35 + 2.24 + 3.04 + 0.88), leg IV: 11.67 (3.40 + 0.38 + 2.90 + 4.09 + 0.90); tibia I L/d: 47. Habitus as in Fig. 5C. 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 0.09; diameter PME 0.12; distance PME-ALE 0.02; AME absent. Sternum slightly wider than long (0.60/0.56). Chelicerae as in Figs 7B–C, with pair of long, hooked frontal apophyses (distance between tips: 0.08); pair of strong proximal apophyses and sclerotized elliptic apophyses proximocentrally, respectively, without modified hairs; pair of small ledges on frontolateral surface distally. Palps as in Figs 5A– B; 7A, 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 15%; 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 15 distinct ones distally.
Variation: Tibia I in other males (n=10): 3.81–4.84 (mean: 4.45).
Female: Similar to male, habitus as in Figs 6C–D. Tibia I in females (n=14, leg I lost in the other specimen): 3.51–4.55 (mean: 4.04). Genital area brown (Figs 6A, 8C), with internal structures nearly invisible through cuticle, without distinct pockets. Dorsal view of epigynum (Figs 6B, 8B) with two nearly elliptic pore plates.
Distribution: The species is known only from the type locality ( Fig. 61 View FIGURE 61 ).
