Figures 15–16

Nyetnops juchuy Dupérré, 2014: 469 , figs 10–13, 16, 21, 22.

Type. Male holotype from Centro Científico Río Palenque (79°22’W 0°35’S), Los Ríos, Ecuador, 30.viii.1977, S. Sandoval, deposited at QCAZ, not examined.

Additional material examined. ECUADOR: Río Palenque (79°22’W 0°35’S), Los Ríos, C. Tapia & N. Dupérré, 1♂, 1♀ ( QCAZ) .

Diagnosis. Males of Nopsma juchuy n. comb. resemble those of Nopsma florencia n. sp. by the small tegulum, not reaching the palpal tibia length but are readily recognized because the tegulum width is one-third of the cymbium length ( Fig. 15B, D ) whereas in N. florencia n. sp. is only one-fifth; the embolus keel bordering two-third of the tip is also diagnostic ( Fig. 16 B–D). Females with straight distal and proximal margins of receptaculum ( Fig 16 G–J).

Description. Male (from Rio Palenque, not type): Total length 7.0. Carapace 3.95 long, 3.1 wide. Sternum 3.2 long, 2.8 wide. Leg measurements: I: 3.80; II: 3.75; III: 3.30; IV: 4.05. Carapace orange-brown with remarkable dorsal pattern ( Fig. 15F ). Chelicerae, palps, sternum orange-brown, endites, labium pale brown ( Fig. 15G ), and legs orange; coxae and trochanters lighter ( Fig. 15E ). Abdomen gray with undefined dorsal pattern ( Fig. 15A ). Anal tubercle and spinnerets lighter than abdomen. Palp with a globose small oval tegulum ( Fig. 15B ) and a embolus with a keel bordering almost two-third of the tip ( Fig. 16 B–E).

Female (from Rio Palenque, not type): Total length 7.5. Carapace 4.1 long, 3.3 wide. Sternum 3.8 long, 3.1 wide. Leg measurements: I: 3.85; II: 3.75; III: 3.35; IV: 4.15. Carapace, chelicerae, labium, legs, coxae, endites and sternum as in male ( Fig. 15H ). Abdomen as in male, but somewhat lighter ( Fig. 15H ). Anal tubercle and spinnerets lighter than abdomen. External genital area with sclerotization around spiracles (ess) strongly noticeable, reaching the anterior side of anterior spiracles ( Fig. 15I ). Internal genitalia with a straight distal margin of receptaculum ( Figs 15J ; 16 G–J).

Distribution. Known only from Ecuador ( Fig. 18G ).
