Female holotype from Sabana Rubia, ( 10°22′8.6″N ; 72°52′33.6″W ), 3200–3400m , Serranía del Perijá , Cesar , Colombia , 16-20-XII.2016 , E. Villarreal , L. Martínez & C. Pinzón leg. (ICN-Ar-10632) . Etymology. The specific epithet is referring to an Andean formation and type locality called “Serranía del Perijá”. It is the most northern branch of the Andean mountains. Diagnosis. Females of Patrera perijaensis n. sp. , resemble those of P. florezi n. sp. and P. wiwa n. sp. , by having the similar shape of hood and n-shaped copulatory ducts ( Figs 16 F–G, 21F–G), but can be diagnosed by having very large and subrounded hood (thinner in P. florezi ), wide copulatory ducts, and larger spermathecae (thinner and smaller respectively in P. florezi ) ( Fig. 17 B–C).

Abdomen: length 3.37, epigastric furrow 0.77 from tracheal spiracle, spiracle 1.37 from base of spinnerets. Epigynum: hood large; lateral borders sclerotized, thin, and parallel; atrium cylindrical; internally with copulatory ducts short, n-shaped and very wide; seminal receptacles inconspicuou; spermathecae large, oval and posteriorly positioned; fertilization ducts almost as long as spermathecae length ( Fig. 17 B–C).
