Eutichurus zarate Bonaldo, 1994: 123, figs 54̄55, 109. Female holotype from Peru, Lima, Bosque de Zárate (Gigantón), 2860 m, 20.IV.1980, I. Franke leg., [11°55'53.6"S 76°28'22.0"W], (MUSM VF5093, not re-examined).
Diagnosis. Males of E. zarate resemble those of E. murgai (Figs 4, 6) by the wide RTA apex, but differ by the sclerotized conductor (Figs 9, 11). Females are promptly recognized by the excavated anterior projections of the epigynum, with digitiform apices, and by the laterally constricted posterior plates (Bonaldo 1994: fig. 54).

Chelicerae with 3 promarginal teeth, the second the largest, and 4 retromarginal teeth separated by twice their width. Abdomen pale yellow. Tarsi I–IV with moderate scopulae, and metatarsi I–II with sparse scopulae. Total length 12.0. Carapace 5.4, long, 4.0 wide. Eye diameters: AME 0.24, ALE 0.27, PME 0.23, PLE 0.22.
