Brachycephalus ferruginus is known only from its type locality: Pico Marumbi (25 26' S; 48 55' W), municipality of Morretes, Parana state, southern Brazil, at an altitude 1200 masl (Alves et al., 2006).
Habitat and Ecology
The species is an Atlantic forest inhabitant. It is found in leaf litter and is active by day. Adult males were always exposed on the litter when calling. A female was found to contain three large, unpigmented maturing oocytes. Direct development of terrestrial eggs was described for Brachycephalus ephippium and it is suspected that this may also be the case for B. ferruginus (Alves et al., 2006).
The species is locally abundant (Alves et al., 2006).
No major threats are currently known for this species.
No conservation measures are known for this species.
Brachycephalus ferruginus can be distinguished from other similar species by a combination of morphological and colour features (Alves et al., 2006).
