Type material.

Holotype: 1♀ (IZCAS-Ar44617), China, Yunnan, Pu’er, Ning’er County, Jinpaoshan Park, 23°3.658′N, 101°3.466′E, hand catch in leaf litter, 26 July 2022, F. Gao leg.

Etymology.

The specific name refers to the type locality and is a noun in apposition.

Diagnosis.

The new species resembles K. princeps Deeleman-Reinhold, 2001 (cf. Figs 1, 2 and Deeleman-Reinhold 2001: 283, figs 391-396) by the similar rectangular epigynal window (Fig. 1A), posteriorly located copulatory openings (Fig. 1A), thin copulatory ducts (Fig. 1B) and globular secondary spermathecae (Fig. 1B). Females can be distinguished by the epigyne with a pair of long, oblique sclerotized area laterally (Fig. 1A; vs. epigyne with a pair of short, similar point-shaped sclerotized area laterally), by the intertubular ducts globular (Fig. 1B; vs. intertubular ducts tubular), by the primary spermathecae elliptical, separated by about their diameter (Fig. 1B; vs. primary spermathecae kidney-shaped, separated by more than twice their diameter), by the secondary spermathecae separated by less than half of their diameter (Fig. 1B; vs. secondary spermathecae separated by more than their diameter), and by the fertilization ducts pointing antero-laterally (Fig. 1B; vs. fertilization ducts pointing postero-laterally). This species also resembles K. fusca Sankaran, 2022 (cf. Figs 1, 2 and Sankaran 2022: 438, figs 1, 2) by the similar rectangular epigynal window (Fig. 1A), posteriorly located copulatory openings (Fig. 1A), thin copulatory ducts (Fig. 1B), globular secondary spermathecae (Fig. 1B) and antero-laterally pointed fertilization ducts (Fig. 1B). Females can be distinguished by the epigyne with a pair of long, oblique sclerotized area laterally (Fig. 1A; absent), by the epigyne without distinct median flap (Fig. 1A; present), by the intertubular ducts globular (Fig. 1B; vs. intertubular ducts tubular, with anterior twist), by the primary spermathecae elliptical, separated by about their diameter (Fig. 1B; vs. primary spermathecae kidney-shaped, separated by more than their diameter), and by the secondary spermathecae separated by less than half of their diameter (Fig. 1B; vs. secondary spermathecae connected to each other). Male unknown.

Carapace reddish-brown, smooth, with distinct radial grooves; fovea longitudinal, slit-like. Chelicerae reddish-brown, massive, with several setae on anterior surface, with three promarginal and seven retromarginal teeth. Endites and labium reddish-brown; endites narrower in middle, subapically with large, semicircular membranous area and dense scopula; labium longer than wide, with subbasal constriction and sparse scopula apically. Sternum reddish-brown, shield-shaped, with intercoxal sclerites between coxae; posterior margin extending between coxae IV; intercoxal sclerites distinctly enlarged, especially between coxae I and II, II and III. Legs yellowish-brown. Leg spination: femur I pl 1; tibiae I plv 9 rlv 8, II plv 7 rlv 6; metatarsi I plv 6 rlv 6, II plv 5 rlv 4. Palp and leg measurements: palp 2.97 (0.92, 0.43, 0.62, -, 1.00), I 8.76 (2.10, 0.69, 2.36, 2.23, 1.38), II 6.78 (1.84, 0.62, 1.61, 1.64, 1.07), III 5.89 (1.56, 0.60, 1.16, 1.59, 0.98), IV 8.29 (2.10, 0.70, 1.87, 2.37, 1.25). Leg formula: 1423. Dorsal opisthosoma brown with grey patterns, oval, with scutum covering half of dorsum surface. Lateral opisthosoma with pale stripes. Ventral opisthosoma yellowish with brown patterns posteriorly, epigastric scutum reddish-brown. Spinnerets yellowish.

Epigyne (Fig. 1A, B). Epigynal field nearly fan-shaped, with a pair of long, oblique sclerotized area laterally; posterior part medially with weakly sclerotized epigynal window. Copulatory openings hidden under epigynal plate. Copulatory ducts thin. Intertubular ducts globular. Primary spermathecae elliptical, separated by about their diameter; secondary spermathecae globular, separated by less than half of their diameter. Fertilization ducts pointing antero-laterally.
