Type material. Male holotype (ICN-Ar 6475) from Colombia, Cundinamarca, San Antonio del Tequendama [04°36’59.21”N 74°21’08.00”W], Bosque El Ermitaño, 12.XII.1997, 2000 m, Santiago leg.

Diagnosis. Males of E. tequendama resemble those of E. tropicus (L. Koch) and E. valderramai Bonaldo by the short, excavated RTA, the extensive, sclerotized, lowered prolatero-apical sector of tegulum and by the long median prong of MA ( Bonaldo 1994: 43, 48). They differ by the absence of a longitudinal keel on the median prong of MA, which is apically bifid ( Figs 20 , 22).

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

Description. Male (Holotype). Colour in ethanol: carapace brownish red, thoracic groove mark darker. Chelicerae, endites and labium dark brownish red. Sternum brownish yellow, with brown margins. Legs orange. Abdomen dark gray. Chelicerae with 3 promarginal teeth, the second the largest, and 4 retromarginal teeth, separated by their length. Tarsi I–IV and metatarsi I–II with dense scopulae, and metatarsi III–IV with moderate scopulae. Total length 14.2. Carapace 7.0 long, 5.2 wide. Eye diameters: AME 0.36, ALE 0.35, PME 0.28, PLE 0.34. Eye interdistances: AME–AME 0.32, AME–ALE 0.43, PME–PME 0.50, PME–PLE 0.73, AME–PME 0.34, ALE–PLE 0.15, clypeus AME 0.25, clypeus ALE 0.32.
