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. 12 ), 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, 11 ). 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. 12 ); pars cephalica elevated posteriorly, with a few scattered setae; thoracic groove absent ( Fig. 12 ). Clypeus, ~ 2x 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. 12 ). 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. 16 ); membranes separating metatarsi and tarsi I–II with translucent fan-shaped ventral extension ( Fig. 16 ); tarsi I–II with three claws, paired claws with ten teeth, unpaired claw small, not reflexed and without teeth ( Fig. 21 ), tarsi III–IV with three claws, paired claws with six teeth, unpaired claw not reflexed, small without teeth ( Fig. 22 ); tarsi I–IV without translucent pulvillar lobe ( Figs 21, 22 ). GENITALIA: Palpal femur prolaterally with stridulatory pick basally ( Fig. 10 ). Palpal tibia prolaterally with brush of five setae ( Fig. 10 ). Cymbium pointed, prolateral surface covered with strong setae; apicodorsal surface with patch of shortened setae ( Fig. 10 ). Bulb spherical ( Figs 10, 11 ). Embolus long and curved, with transparent serrated membrane, reaching tip and forming a crown ( Figs 10, 11 ). FIGURES 10–13. Nyetnops juchuy n. sp. Male 10–12. Female 13. 10.

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. 13 ). Other material examined. Los Ríos : Río Palenque, 24–27. ii.1977, 1 ♂1♀, J.
