Population [top]

Population:This is considered to be a rare species (J.M. Padial pers. comm. November 2009). In 1941, 31 specimens were collected at Río Yanamonte (Lynch 1975), while six frogs were found over two hours of searching at the same locality in January 2006 (Lehr and Aguilar 2006).
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It is a terrestrial species, inhabiting montane cloud forest, but it is not known whether or not it occurs in degraded areas. Frogs were found under rocks and rotten wood next to the river bank of Río Yanamonte at 11:00–13:00 hr (Lehr and Aguilar 2006). It is presumed to breed by direct development. Lynch (1975) reported females having from 18 to 20 eggs.
Continuing decline in area, extent and/or quality of habitat:Yes
Movement patterns:Not a Migrant
