This species is known only from the type locality: forested mountain slopes in the district of Theodoro de Oliveira, municipality of Nova Friburgo, Rio de Janeiro state, Brazil. This area lies within the Serra dos Órgãos (a subdivision of the Serra do Mar mountain range), in the Atlantic Forest domain (Pombal et al. 2008). It is found between 1,200-1,400 m asl (Pombal et al. 2008).
Habitat and Ecology
This species is found in montane Atlantic Forest. Of reclusive habits, individuals can be found at night in the leaf litter and within holes at the base of trees (Pombal et al. 2008). This species is believed to breed by direct development (Pombal et al. 2008).
The cryptic habits of Holoaden make it difficult to find these frogs, thus making them appear rarer than they may actually be (Pombal et al. 2008).
Habitat destruction in the form of urban development (commercial and residential) and land use change (for e.g. agriculture) is a general threat to Atlantic forests.
This species is found within the Parque Estadual dos Três Picos, a recently created conservation unit that includes much of the Serra dos Órgãos mountain range (Pombal et al. 2008).
Red List Status
Data Deficient (DD)
Listed as Data Deficient since it has only recently been
described, and there is still very little information on its extent of occurrence,
status and ecological requirements.
