Type material.

Holotype: male (SWK12-2610) in UBCZ from Malaysia: Sarawak: Mulu Nat. Pk., Summit Trail near Camp 1, 4.0486°N, 114.8610°E to 4.0483°N, 114.8614°E, 270 m elev., 21 March 2012, Maddison/Piascik/Ang WPM#12-072. Paratype: female (SWK12-2639) in UBCZ from Malaysia: Sarawak: Mulu Nat. Pk., Summit Trail near Camp 1, 4.0480°N, 114.8626°E to 4.0478°N, 114.8630°E, 290-320 m elev., 22 March 2012, Piascik/Ang/Andyson WPM#12-077.

Etymology.

From the name of the type locality (a noun in apposition).

Diagnosis.

Dark with only a dusting of golden scales, unlike the similar but more thoroughly scale-covered K. intexta (Figs 23-28 View Figures 23–28 vs. 29-34). Embolus shorter than that of K. intexta , arising at 11 o’clock (Figs 16 View Figures 16–22 vs. 22).

Description.

Male (based on holotype). Carapace length 2.85; abdomen length 3.05. Carapace dark brown, with white scales around cephalic region, between AME and sparse on thoracic region. Clypeus very narrow. Chelicera dark brown, elongate and projected, with a line of white scales on the prolateral face. Retromarginal tooth with two cusps, the more lateral long and curved (Fig. 5 View Figures 2–9 ). Palp with elongate RTA. Embolus narrow and curved, but short, arising distally on the tegulum. Endite subrectangular, with no projection, dark brown. Labium dark brown and sternum light brown, with depressions along coxae I. Leg I light brown, with mid patella, mid tibia, proximal area of metatarsus and entire tarsus yellow. Legs II-IV yellow. Length of femur I 2.10, II 1.70, III 1.40, IV 1.65; patella + tibia I 3.10, II 2.40, III 1.65, IV 2.35; metatarsus + tarsus I 1.85, II 1.75, III 1.50, IV 1.70. Leg spination reduced: femur I d0, p0-0-1-0 (or p0-0-2-0), II d1-1-0, p0-0-1-0, III 0, IV d1-1-0, r0-0-1-0; patella I-IV 0; tibia I v2-2-2 (asymmetrical), II v1r-1r-1p, III-IV 0; metatarsus I-II v2-2, III 0, IV v0-0-1p. Abdomen dorsally dark brown, with two transverse wide light stripes, and a third over anal tubercle; ventrally gray.

Female (based on paratype SWK 12-2639). Carapace length 2.7; abdomen length 3.55. Color as in male, except when mentioned. Chelicera light brown. Retromarginal tooth with two cusps, the distal one almost twice the size of the other, both acute. Legs II-IV with narrow stripes of white scales. Length of femur I 1.90, II 1.50, III 1.45, IV 1.85; patella + tibia I 2.60, II 1.90, III 1.75, IV 2.60; metatarsus + tarsus I 1.40, II 1.30, III 1.60, IV 1.90. Leg spines as in male, except for femur III, as in II. Abdomen as in male, except for stripes, medially interrupted; ventrally white, with two longitudinal dark brown stripes extending from booklungs to spinnerets. Epigyne with a pair of small copulatory openings distant from the posterior border, which has a medial excavation; internally, copulatory ducts fuse with glandular portions, spiral backwards and enter the large spermathecae, from which fertilization ducts emerge.
