Pristimantis marmoratus (Boulenger 1900)

Holotype: BMNH 1947.2.16.92.

Type locality: “ Foot of Mt. Roraima, 3,500 feet (1,066 m),” Guyana .

Distribution: Region 5. Lowlands and uplands in Guayana Shield in Venezuela, Guyana, Suriname, and French Guiana. In Venezuela, restricted to Gran Sabana in eastern Bolívar State, 600– 1,800 m asl.

Remarks: Type locality (same as for Oreophrynella macconnelli; see its account) is not clear and subject of debate. Kok et al. (2018) suggest it is in Venezuela, contrary to the opinion herein (see Remarks on O. macconnelli), and provide a thorough morphological description, vocalization, natural history, and phylogenetic relationships. Probably a species complex. In Pristimantis unistrigatus species group according to Hedges et al. (2008) and Kok et al. (2018), but not assigned to any species group by Padial et al. (2014).
