Description
Male (holotype): Total length 2.62 (2.71 with clypeus), prosoma 0.85 long, 1.06 wide, opisthosoma 1.77 long, 1.12 wide. Leg I: 31.83 (7.91, 0.43, 7.88, 13.01, 2.60), legs II and III missing, leg IV: 19.55 (5.77, 0.42, 4.75, 7.37, 1.24); tibia I L / d: 66. Eye interdistances and diameters: PME – PME 0.16, PME 0.14, PME – ALE 0.04, AME absent. Sternum width / length: 0.78 / 0.66. Habitus as in Fig. 2 View Figure 2 E and F. Dorsal shield of prosoma yellowish, with black lateral margins and narrow, dark median line; sternum black. Legs brownish, but slightly whitish on distal parts of femora and tibiae, with distinct darker rings on subdistal parts of femora and tibiae. Opisthosoma yellowish, with large black spots. Thoracic furrow shallow, but distinct. Clypeus unmodified. Ocular area slightly elevated and separated from rest of prosoma. Chelicerae with pair of proximo-lateral apophyses (pa in Fig. 2 View Figure 2 C and D), pair of distal apophyses (da in Fig. 2 View Figure 2 C and D) on front-lateral surface, pair of strong frontal apophyses (arrows in Fig. 2 View Figure 2 C and D) each bearing scales and pair of long, hooked frontal apophyses (fa in Fig. 2 View Figure 2 C and D; distance between tips: 0.05). Palp as in Fig. 1 View Figure 1 A and B; trochanter with short retrolateral apophysis (as long as wide, arrow 1 in Fig. 1 View Figure 1 B) and small ventral apophysis (arrow 2 in Fig. 1 View Figure 1 B); femur with small retrolateral apophysis (arrow 3 in Fig. 1 View Figure 1 B); patella large; procursus simple proximally, but complex distally, with prolateral distal apophysis bearing scales and two angular apophyses (arrows 1 and 2 in Fig. 1 View Figure 1 C), curved retrolateral sclerite (arrow 3 in Fig. 1 View Figure 1 C) and spine-shaped, weakly sclerotised retrolatero-distal apophysis (arrow 4 in Fig. 1 View Figure 1 C); bulb simple, no other apophyses, except for embolus. Retrolateral trichobothria on tibia I at 6 % proximally; legs with short vertical setae on metatarsi and tarsi; tarsus I with 12 distinct pseudosegments.
Female (paratype, SYNU-Ar 00413): Similar to male, habitus as in Fig. 2 View Figure 2 G and H. Total length 3.20 (3.36 with clypeus), prosoma 0.90 long, 1.05 wide, opisthosoma 2.30 long, 1.78 wide; leg I missing. Eye interdistances and diameters: PME – PME 0.17, PME 0.14, PME – ALE 0.03, AME absent. Sternum width / length: 0.64 / 0.62. Epigyne (Fig. 2 View Figure 2 A) sclerotised and posteriorly slightly curved, without pockets. Vulva with wavy anterior arch (aa in Fig. 2 View Figure 2 B) and pair of anteriorly blunt and posteriorly pointed pore plates (nearly elliptic, pp in Fig. 2 View Figure 2 B).
Variation. Tibia I in the male paratype (SYNU-Ar 00412): 7.88. Tibia I in another female paratype (SYNU-Ar 00414): 7.69.
Diagnosis
The new species resembles K. bachma Yao & Li, 2018 ( Nie et al. 2018: 481, figs 1 A – D, 2 A – H) by having similar male chelicerae (Fig. 2 View Figure 2 C and D) and epigyne (Fig. 2 View Figure 2 A), but can be distinguished by procursus with two angular prolateral apophyses (arrows 1 and 2 in Fig. 1 View Figure 1 C vs. nearly half-round apophysis in K. bachma ), curved retrolateral sclerite (arrow 3 in Fig. 1 View Figure 1 C vs. square in K. bachma ) and spine-shaped, weakly sclerotised retrolatero-distal apophysis (arrow 4 in Fig. 1 View Figure 1 C vs. absent in K. bachma ), by pore plates anteriorly blunt and posteriorly pointed (nearly elliptic, pp in Fig. 2 View Figure 2 B vs. triangular in K. bachma ) and by vulval anterior arch wavy (aa in Fig. 2 View Figure 2 B vs. straight in K. bachma ).
Etymology
The specific name refers to the type locality; noun in apposition.
Distribution
