Figures 70A‒G ; 71A‒F

Nops quito Dupérré, 2014: 468 , figs 6–9, 15, 19, 20. Male holotype from Quito , 2810m, (00°W, 00°S), Pichincha Province, Ecuador, 10.x.1998, S. Castelo ( QCAZ; not examined).

Additional material examined. ECUADOR: Chimborazo: Alausi (2°13′40.9″S, 78°50′30.7″W), olaria beira rodovia 2668 m, 29.iii.2011, A. Chagas, A. Giupponi, A.B. Kury, 2♂ 3♀ ( MNRJ 06310 ) . Pichincha: Los dos Puentes (00°11S, 78°29W), Quito , 2810 m, 9.i.2000, M. Guerra, 1♂ ( QCAZ). Guayllabamba, 4.vii.1992, R. Sandoval, 1♀ ( QCAZ).

Diagnosis. Males and females resemble similar congener N. variabilis , which have a similar abdominal pattern as in figure 6K, and the posterior unpaired claws small ( Fig. 5C ); but can be distinguished by having the PLS two times longer than the PMS similar to the Fig. 7A‒B .

Description. Male (Pichincha: QCAZ): Carapace, chelicerae and legs orange, coxae and trochanters lighter ( Fig. 70A ). Endites, labium and sternum orange. Abdomen light gray, dorsal pattern as in figure 6K, lighter ventrally. Anal tubercle and spinnerets light gray. Total length 7.8. Carapace 4.7 long, 3.8 wide. Sternum 4.2 long, 3.6 wide. Leg measurements: I: 3.7; II: 3.6; III: 3.3; IV: 3.85. Posterior unpaired claws small, as in other three‒clawed spiders ( Fig. 5C ). PLS longer than PMS. Palp with straight embolus but twisted and shorter than palpal tibia ( Figs 70B‒D ; 71A); embolar tip with a wide cut on ventral side and one short extensions ( Fig. 71B‒C ).

Female (Pichincha: QCAZ): Carapace, chelicerae, labium, coxae, legs, endites and sternum as in male. Abdomen as in male ( Fig. 70E ). Anal tubercle and spinnerets whitish yellow. Total length 8.3. Carapace 4.9 long, 3.9 wide. Sternum 4.5 long, 3.8 wide. Leg measurements: I: 3.8; II: 3.75; III: 3.4; IV: 3.95. Posterior unpaired claws and PLS as in male. External genital area with strongly sclerotized anterior plate and lep, remarkable ess ( Fig. 70F ). Internal genitalia with narrow invagination on receptaculum, with three small lobes and uterus externus with narrow base ( Figs 70G ; 71D‒E).

Distribution. Known from Ecuador ( Fig. 69B ).
