Identification. According to Hedges et al. (2008), a member of the Pristimantis frater species group, but unassigned to any species group by Padial et al. (2014). A small frog, SVL 12.5–21.3 mm in males and 22.2–31.5 mm in females. It can be identified by dorsum shagreen; venter coarsely areolate. Discoidal fold evident. Dorsolateral folds present or absent. Upper eyelids usually with small tubercles. Finger I <II. Toe V >> III. Dorsum varies from pale tan to reddish brown with dark brown marking, sometimes with an H- or W-shaped mark on the scapular region; venter pale gray. Labial bars present. Ventral and dorsal surfaces of thighs are brown to rosered ( Duellman 1978, 2005, Rodriguez and Duellman 1994, Duellman and Lehr 2009). There are no other similar Pristimantis species in the area with small tubercles on the upper eyelids.

Distribution. Pristimantis ockendeni has a controversial distribution (see Elmer and Cannatella 2008, Duellman and Lehr 2009), but currently is restricted to Amazonia of Bolivia, Brazil, Colombia, Ecuador, and Peru, from 300 to 1800 m a.s.l. (Ocampo et al. 2017, Frost 2019).

Remarks. In respect to coloration and dorsal pattern, P. ockendeni can be highly variable, and this character is insufficient to identify this species.
