Range Description

Pristimantis jester is known from the tops of the two highest summits (Mt. Wokomung and Little Ayanganna) of the Wokomung Massif of west-central Guyana (1411–1650 masl)(Means and Savage, 2007). It is also possible that the species may be found on Mt. Maringma to the east of Wokomung (B. Means, pers. comm. 2008).

Habitat and Ecology

The species inhabits dense cloud forest approaching tepui scrub forest. The trees are no more than 10 m high with trunks, stems, and leaves densely covered with epiphytes ranging from mosses and a gooey, slimy alga to bromeliads and large aroids. The forest included trees of the genera Podocarpus, Weinmannia, and Clusia. Individuals of this species were collected at about 2 m off the ground during light rain alternating with cloudy skies and blowing mists (Means and Savage, 2007).

Population

Only 4 or 5 individuals have been found during four expeditions to the Wokomung Massif. It seems to be as uncommon as or more so than Pristimantis dendrobatoides (B. Means, pers. comm. 2008).

Population Trend

unknown

Major Threats

No major threats have been observed for this species. Introduced microbes and/or chemicals could be an unobservable threat (B. Means pers. comm. 2008).

Conservation Actions

No conservation measures are known for this species. However, there is ample habitat to support this species on three tepui cloud forests, which are extensive on these tepuis, and the tepuis are not suitable for human agriculture or occupancy (B. Means, pers. comm. 2008).

Red List Status

Least Concern (LC)

Rationale

Listed as Least Concern in view of its occurrence in an area where its habitats are not significantly threatened, presumed stable population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Taxonomic Notes

Pristimantis jester can be distinguished from other similar species by a combination of morphological features, colour pattern and the production of odorous skin secretions (Means and Savage, 2007).
