Male (holotype; Figs 7A, B View Figure 7 , 9A View Figure 9 ). Total body length 2.15. Carapace 1.02 long, 0.77 wide; opisthosoma 1.13 long, 0.81 wide. PER procurved slightly. Eye sizes and interdistances: ALE 0.05, PME 0.04, PLE 0.05; PME-PME 0.06, PME-PLE 0.01, ALE-PLE 0.01. Clypeus 0.03 high. Leg measurements: I 2.75 (0.85, 0.34, 0.69, 0.51, 0.36); II 2.37 (0.75, 0.33, 0.52, 0.44, 0.33); III 1.98 (0.59, 0.28, 0.36, 0.44, 0.31); IV 2.47 (0.77, 0.31, 0.56, 0.45, 0.38). Leg spination: femora I-II d1; patellae I-IV d1; tibiae III p1 d1 r1 v2, IV p1 r2 v2; metatarsi III p1 d1 r1, IV p1 r1.

Coloration (Fig. 9A View Figure 9 ). Carapace yellow, with dark yellow radial grooves. Fovea reddish-brown. Chelicerae, labium and gnathocoxae yellow; sternum yellowish. Sternum without markings. Legs yellow. Opisthosoma oval, grey. Spinnerets grey.

Palp (Fig. 7A, B View Figure 7 ). Patellar apophysis tip widening; distal part wider that apophysis length. Retrolateral tibial apophysis curved and serrated, almost as long as tibia, C-shaped in retrolateral view. Cymbium elongate egg-shaped, ca 1.7 × longer than wide, cymbial furrow almost 2 × shorter than cymbium. Bulb oval. Conductor absent, but tegular outgrowth present, sclerotized, located retrolaterally (arrowed in Figs 3B View Figure 3 , 7A, B View Figure 7 ). Middle of sperm duct bent in U-shape. Embolus slender and whip-shaped; base of embolus arising at 3:00-5:00 o’clock position, clockwise, makes ~ 360° loop.

Female (paratype IZCAS-Ar44664; Figs 8A, B View Figure 8 , 9B View Figure 9 ). Total body length 1.76. Carapace 0.69 long, 0.50 wide; opisthosoma 1.07 long, 0.78 wide. Eye sizes and interdistances: ALE 0.03, PME 0.01, PLE 0.02; PME-PME 0.05, PME-PLE 0.01, ALE-PLE 0.02. Clypeus 0.02 high. Leg measurements: I 1.56 (0.48, 0.20, 0.35, 0.28, 0.25); II 1.38 (0.42, 0.19, 0.28, 0.25, 0.24); III 1.24 (0.37, 0.18, 0.22, 0.26, 0.21); IV 1.62 (0.48, 0.20, 0.34, 0.34, 0.26). Leg spination: femora I-III d1; patellae I-IV d1; tibiae III-IV p1 d1 r1 v1; metatarsi III-IV p1 d1 r1.

Coloration (Fig. 9B View Figure 9 ). As in male but body pale yellow.

Epigyne (Fig. 8A, B View Figure 8 ). Copulatory openings large, ~ 4 × shorter than epigyne width, located on posterior edge. Copulatory ducts intertwined, shorter part with twist, longer part with two twists. Secondary spermathecae oval, almost as long as primary spermatheca. Primary spermathecae elongate. Fertilization ducts directed at 10:00 o’clock position from spermathecae.

Variation.

Females (n = 3): total body length 1.49-1.76, carapace 0.68-0.71 long, 0.50-0.52 wide, opisthosoma 0.81-1.05 long, 0.60-0.75 wide.

Etymology.

The specific epithet refers to the type locality; noun in apposition.

Distribution.

Known only from the type locality (Fig. 30 View Figure 30 ).
