Other material examined. COLOMBIA, Cundinamarca: San Antonio del Tequendama, Parque Natural de Chicaque (4°36′22.87″N; 74°18′20.98″W), 1368m, ♁1, 15–17.X.2016, Estudiantes Curso de Arañas Universidad Nacional de Colombia leg. (ICN-Ar-10603); ♁1, same data (ICN-Ar-10610).
Etymology. The specific epithet is a patronym given in honor of Javier Sampedro, for his efforts in transmiting the evolutionary thinking to the people in an understandable way.
Diagnosis. Males of Patrera sampedroi n. sp. resemble those of P. carvalhoi n. sp., by having prominent tutacular groove on the cymbium, S-shaped and long embolus, and entire, apically bilobed retrolateral tibial apophysis (Fig. 15 C–E), but can be distinguished by their long, wide retrolateral tibial apophysis (smaller and thinner in P. carvalhoi) (Fig. 19 B–D).
