Figs 10–13View FIGURES 10 – 13, 16View FIGURES 14 – 16. 14, 21, 22View FIGURES 17 – 22.

Type material. Male holotype from Ecuador, Los Ríos, CCRP, 30 Ago. 1977, S. Sandoval (deposited at QCAZ). EXAMINED.

Etymology. The specific name is a non-Latin adjective (invariable), taken from the Kichwa language meaning small.

Diagnosis. Males and females are diagnosed by their strong carapace pattern ( Fig. 12View FIGURES 10 – 13), much stronger than in the other species Nyetnops guarani Platnick & Lise 2007  . Additionally, males are distinguished by their long embolus with a unique serrated transparent membrane ( Figs 10, 11View FIGURES 10 – 13).

Description. Male: Total length: 3.1; carapace length: 1.1; carapace width: 0.9.

CEPHALOTHORAX: Carapace light orange with purplish-gray mesh-pattern, reticulate and oval, widest between coxae II –III ( Fig. 12View FIGURES 10 – 13); pars cephalica elevated posteriorly, with a few scattered setae; thoracic groove absent ( Fig. 12View FIGURES 10 – 13). Clypeus, ~ 2 x as high as AME. Sternum orange, smooth, longer than wide, covered by scattered setae. Labium and endites light orange, wide, strongly convergent, rounded distally. Chelicerae light orange; with median lamina with rounded tip; lateral surface with numerous stridulatory ridges. EYES: 2 large, separated by half their width, surrounded by oval ring of black pigment ( Fig. 12View FIGURES 10 – 13). ABDOMEN: Oval, purplish-gray dorsally, whitish ventrally. LEGS: Orange; without spines; total length leg I: 0.50; II:0.42: III:0.39: IV: 0.51; metatarsi I –IV entire; tarsi I –IV divided into two subsegments; metatarsi I –II without translucent ventral keel ( Fig. 16View FIGURES 14 – 16. 14); membranes separating metatarsi and tarsi I –II with translucent fan-shaped ventral extension ( Fig. 16View FIGURES 14 – 16. 14); tarsi I –II with three claws, paired claws with ten teeth, unpaired claw small, not reflexed and without teeth ( Fig. 21View FIGURES 17 – 22), tarsi III –IV with three claws, paired claws with six teeth, unpaired claw not reflexed, small without teeth ( Fig. 22View FIGURES 17 – 22); tarsi I –IV without translucent pulvillar lobe ( Figs 21, 22View FIGURES 17 – 22). GENITALIA: Palpal femur prolaterally with stridulatory pick basally ( Fig. 10View FIGURES 10 – 13). Palpal tibia prolaterally with brush of five setae ( Fig. 10View FIGURES 10 – 13). Cymbium pointed, prolateral surface covered with strong setae; apicodorsal surface with patch of shortened setae ( Fig. 10View FIGURES 10 – 13). Bulb spherical ( Figs 10, 11View FIGURES 10 – 13). Embolus long and curved, with transparent serrated membrane, reaching tip and forming a crown ( Figs 10, 11View FIGURES 10 – 13).

Female: Total length: 4.0; carapace length: 2.5; carapace width: 1.2. CEPHALOTHORAX: Carapace as in male; pars cephalica less elevated than in male. Sternum, labium, endites and chelicerae as in male. ABDOMEN: Oval, purplish-gray dorsally, light purplish-gray ventrally with whitish median band. LEGS: as in male; total length leg I: 0.59; II:0.52: III:0.50: IV: 0.61; palpal femur with stridulatory pick basally; palpal tibia prolaterally with brush of seven setae; palpal tarsus slightly expanded, without claw, ventral surface densely covered with strong setae; apicodorsal surface with patch of shortened setae. GENITALIA: Epigastric region slightly sclerotized ( Fig. 13View FIGURES 10 – 13).
