Pristimantis zeuctotylus ( Lynch and Hoogmoed 1977)

Holotype: RMNH 17701 .

Type locality: “ West slope, Vier Gebroeders Mountain , Sipaliwini, Nickerie District, Suriname.”

Distribution: Region 4. Widely distributed in Amazonia, from southern Colombia through Venezuela, Brazil, Guyana, and Suriname to French Guiana. In Venezuela, only known from a few localities in southern Amazonas State.

Remarks: Barrio-Amorós and Molina (2006) doubted the validity of this taxon, which is distinguished from Pristimantis vilarsi only by absence of tarsal fold (present on P. vilarsi ) and rounded palmar tubercle (variable in P. vilarsi ). Araujo de Oliveira et al. (2017) show a maximum likelihood tree in which P. zeuctotylus from Suriname is presented as sister to P. vilarsi from Colombia; this should be confirmed with specimens from type localities of both species. In Pristimantis conspicillatus species group of Hedges et al. (2008) and Padial et al. (2014).
