Description
As all brachycephalids, Brachycephalus ferruginus are small: adult males measure 11.6-12.5 mm (0.46-0.49 in) and females 13.0-14.5 mm (0.51-0.57 in) in snout-vent length; this miniaturization is associated with loss of phalanges in hands and feet. The body is robust and toad-like. There is no tympanum. The general color is orange. There are dorsal reddish-brown irregular markings; the lateral surfaces have small dark brown spots, and the belly has brownish spots and small dots. The skin on top of the head and central part of the back body is smooth and without dermal co-ossification, whereas skin on the dorso-lateral surfaces of body, flanks, and dorsal surface of thighs is granular.
A dissected female was found to contain three eggs. Eggs are probably terrestrial with direct development, as in B. ephippium.
Habitat and conservation
Brachycephalus ferruginus inhabit the leaf litter in the Atlantic Rainforest. They are active by day; males are exposed on the litter when calling. The species can be locally abundant. There are no known threats to this species, but it is only known from a single location.
