Camps I, II, and IV. 15 and 16 March 2002. EBRG 4676–78 (adult males).
These specimens fall within the variation of Pristimantis cavernibardus described by Myers and Donnelly (1997) in the original description. Because of a lack of adequate comparative material, we are unable to refer our specimens to P. cavernibardus with complete confidence beyond comparisons with the original species description. We recognize the need for a more comprehensive study of this species. This is an abundant species on the summit of Sarisariñama, where it calls during the rainy or cloudy days from roots and moss. Barrio-Amorós and Molina (2006) described Pristimantis aracamuni from the summit of Aracamuni, a granitic mountain about 380 km SSW from Sarisariñama, but sharing some especial features that clearly indicate its common origin. Both species show diurnal activity, a trill call, lack of vomerine teeth, notched discs, and a green lichen color and pattern.
