Type material: Holotype: ♀ from COLOMBIA: Boyacá: [4.6776, -74.1485], between Alto Belen and San Jose, 23 September 1985, J. Sturm leg. ( MCZ 46472 View Materials ). GoogleMaps  

Etymology. The specific name refers to the type locality; noun in apposition.

Diagnosis. Females of S. boyaca   sp. n. resemble those of S. gaita   , S. parang   and S selenopoides   by the presence of an anterior, transversal furrow on the epigyne ( Figs 83 View FIGURES 83−88 , 112, 114, 116 View FIGURES 112−116 ). They are distinguished from S. gaita   by the presence of an anterior atrium bearing the CO (absent in the latter species) and from S. parang   and S. selenopoides   by the lateral lobes completely separated by the MS ( Fig. 83 View FIGURES 83−88 ) (touching each other posteriorly in S. parang   and medially in S. selenopoides   ).

Description. Female (holotype): Prosoma brownish orange with dark brown margins and brown marks along thoracic striae, lateral margins of cephalic region and extending posteriorly from between PME; fovea brown; eye borders black. Chelicerae and palps brownish orange. Legs brownish orange with large pale brown spots at the base of spines. Labium pale brownish orange, distally cream colored. Endites pale yellowish cream, distally cream colored. Sternum pale yellow with pale orange margins. Opisthosoma cream colored with no distinctive pattern; dorsally with two pairs of round brown muscle impressions; ventrally with two slightly curved lines of muscle impressions. Spinnerets yellowish-cream colored. Total length 10.9. Prosoma: 3.8 long, 3.5 wide. Opisthosoma: 6.8 long, 5.1 wide. Eyes: diameters: 0.20, 0.26, 0.20, 0.26; interdistances: 0.10, 0.06, 0.30, 0.28, 0.22, 0.20. Legs (2143): I: 13.7 (3.8, 1.8, 3.6, 3.2, 1.3); II: 14.8 (4.4, 1.8, 3.9, 3.4, 1.3); III: 12.0 (3.7, 1.4, 3.0, 2.8, 1.1); IV: 13.5 (4.0, 1.4, 3.3, 3.5, 1.3). Epigyne: epigynal field longer than wide; lateral lobes running parallel and diverging posteriorly; anterior atrium oval, wider than long ( Fig. 83 View FIGURES 83−88 ). Vulva: internal ducts strongly convoluted; glandular projection small, rounded, close to CO; SP elongated, curved anteriorly; FD long, curved, antero-laterad ( Figs 84−85 View FIGURES 83−88 ).

Male. Unknown.

Distribution. Only known from the type locality in Colombia ( Fig. 117 View FIGURES 117−118 ).
