Type material.

Holotype ♂, COLOMBIA: Putumayo, Parque Natural Nacional La Paya, Cabaña Viviano Cocha; 0°7'S, 74°56'W; 320 m; 15-20 Jul. 2003; R. Cobete leg; IAvH-I 3786. Paratypes: 1♀; same data as for holotype; IAvH-I 3796 • 1♀; same data as for holotype; IAvH-I 3806.

Diagnosis.

Males of N. paya sp. nov. resemble those of N. leticia sp. nov. by having an oval tegulum reaching one-third of the cymbium length (Figs 2C, D , 4E, F ), but can be distinguished by having a straighter embolus with membranous keel restricted to the opening tip (Fig. 6G, H ) (curved, with membranous keel surrounding the embolus in N. leticia ; Fig. 6E, F ). Females differ from those of N. juchuy , the only other Nopsma species known by females, by the external genitalia strongly sclerotized around spiracles, with V-shaped margin on posterior plate (Fig. 4G ) (concave margin on posterior plate, weak sclerotization around spiracles in N. juchuy ; Sánchez-Ruiz et al. 2020: fig. 15I); internally with median concavity on distal margin of receptaculum (Figs 4H , 7B ) (straight distal margin in N. juchuy ; Fig. 7A , Sánchez-Ruiz et al. 2020: fig. 16G-J).

Description.

Male (holotype): Total length (approximately) 3.04. Carapace 1.60 long, 1.29 wide. Sternum 0.94 long, 0.81 wide. Leg measurements: I: 5.09; II: 4.84; III: 4.58; IV: 6.14. Carapace orange-brown with disperse dorsal pattern of dark brown stains (Fig. 4A ). Chelicerae, palps, sternum, labium, endites and legs light orange-brown, except coxae and tarsi pale orange (Fig. 4A, B ). Abdomen dorsally dark gray with dark patches, but not forming a pattern, ventrally light gray. Anal tubercle and spinnerets pale light brown. Palp with oval, pear-shaped tegulum with retrolateral torsion (Fig. 6G, H ) and a straight embolus with membranous keel only at the opening tip (Fig. 6G, H ). Female (paratype, IAvH-I 3796): Total length 5.24. Carapace 1.80 long, 1.55 wide. Sternum 1.07 long, 0.99 wide. Leg measurements: I: 5.21; II: 5.01; III: 4.58; IV: 6.37. Coloration as in male. External genitalia strongly sclerotized around spiracles and in the anterior plate, with V-shaped margin on posterior plate (Fig. 4G ); internal genitalia with median concavity or invagination on distal margin of receptaculum, slightly sloping on sides (Figs 4H , 7B ).

Etymology.

The specific name is a noun in apposition taken from the type locality.

Variation.

Females (n=2): total length: 4.97-5.24; carapace length: 1.64-1.80.

Distribution.

Known only from the type locality (Fig. 8 ).

Preservation status.

Preserved in 80% ethanol. Male holotype with only a half of the abdomen, left palp dissected in a separate microvial. Female paratype IAvH-I 3796 in good condition, genitalia dissected in a separate microvial.
