Eye sizes and interdistance: ALE 0.03, PLE 0.02; ALE-PLE 0.03. Clypeus 0.12 high. Chelicerae with three promarginal and two retromarginal teeth. Leg measurements: I 2.84 (0.80, 0.26, 0.68, 0.62, 0.48); II 2.71 (0.77, 0.25, 0.62, 0.61, 0.46); III 2.50 (0.69, 0.24, 0.56, 0.58, 0.43); IV 3.11 (0.85, 0.24, 0.76, 0.74, 0.52). Leg spination: femora I p1 v4, II-IV v4; patellae II-IV d1; tibiae I p1, II p1 d1, III-IV p1 r1; metatarsi III-IV p1 r1 v1.
Coloration (Figs 28E View Figure 28 , 29E View Figure 29 ). Carapace pale yellow, with a few long brown hairs. Fovea longitudinal, reddish-brown. Four eyes, white. Chelicerae, labium, and gnathocoxae pale yellow, with long brown hairs; sternum yellowish. Legs yellow. Opisthosoma oval, pale yellow. Spinnerets white.
Palp (Fig. 25A, B View Figure 25 ). Patella with apophysis retrodorsally, tip hook-shaped. Tibia with black, serrated retrolateral apophysis, little curved, point dorsally. Cymbium 2 × longer than wide, 6 × longer than cymbial furrow. Cymbial furrow shallowed, originated on the inside of cymbium. Bulb oval. Conductor oval, almost as wide as middle of sperm duct. Middle of sperm duct bent in upturned U-shape. Embolus slender and whip-shaped, almost half the perimeter of bulb. Base of embolus arising at 7:30 o’clock position.
Female (paratype IZCAS-Ar44712; Figs 26A, B View Figure 26 , 28F View Figure 28 , 29F View Figure 29 ). Total body length 1.73. Carapace 0.74 long, 0.55 wide; opisthosoma 0.99 long, 0.76 wide. Eye sizes and interdistance: ALE 0.03, PLE 0.02; ALE-PLE 0.03. Clypeus 0.10 high. Chelicerae with three promarginal and two retromarginal teeth. Leg measurements: I 2.54 (0.74, 0.24, 0.58, 0.54, 0.44); II 2.44 (0.72, 0.23, 0.53, 0.53, 0.43); III 2.30 (0.64, 0.22, 0.52, 0.52, 0.40); IV 2.89 (0.80, 0.25, 0.71, 0.66, 0.47). Leg spination: femora I p1 v4, II-IV v4; tibiae III-IV p1; metatarsi III-IV p1 r1 v1.
Coloration (Figs 28F View Figure 28 , 29F View Figure 29 ). As in male.
Epigyne (Fig. 26A, B View Figure 26 ). Epigynal plate 1.1 × wider than long. Depression obvious, ends with copulatory openings. Copulatory ducts long, almost 1.5 × longer than width of primary spermathecae, strongly curved to almost 80° angle, base bifurcate. The short one connected to secondary spermathecae, the other connected to primary spermathecae. Secondary spermathecae oval, as wide as primary spermathecae. Fertilization ducts directed at 9:00 o’clock position from spermathecae.
Variation.
Females (n = 5): total body length 1.50-2.07, carapace 0.69-0.80 long, 0.51-0.59 wide, opisthosoma 0.75-1.27 long, 0.61-1.02 wide.
Etymology.
The specific epithet refers to the type locality; noun in apposition.
