Frogs of the genus Phrynopus were believed to inhabit the Andes of Colombia, Ecuador, Bolivia and Peru, between 1000 and 4400 meters above sea level. However, the genus proved to be polyphyletic and recent molecular data indicate that it is restricted only to central Peru only. Currently 19 species are recognized, many of them described during the last 15 years. The genus now appears to be one of the most speciose groups of frogs in the humid paramo and cloud forest habitats of the Andes. The actual diversity of this genus is far from being well known, and new species continue to be found as herpetological surveys are carried out in previously unexplored or poorly known areas. Yanachaga Chemillén is a Peruvian National Park in Departamento Pasco, in which there is a remarkable amphibian diversity. Intensive fieldwork by Chaparro et al. (2008) in August and September 2007 produced several new species of frogs, among them, two new Phrynopus. With these additions, the diversity of the genus Phrynopus raises to 21 species. The new species are sympatric and described from elfin forests and puna grasslands (3363–3589 m) on the eastern slopes of the Andes. Phrynopus miroslawae sp. nov. is a medium-sized species characterized by lacking vomerine teeth and tympanic membrane. Phrynopus nicoleae sp. nov. is a small species characterized by lacking tympanic membrane and by having vomerine teeth. These frogs have been described in the following paper. J, C. Chaparro, J. M. Padial, and I. De La Riva. 2008. Two sympatric new species of Phrynopus (Anura: Strabomantidae) from Yanachaga Chemillen National Park (central Peruvian Andes). Zootaxa 1761: 49-58
