Brachycephalus olivaceus is a species of frog in the family Brachycephalidae. It is very tiny and was one of seven new species described by LF Ribeiro and a team of scientists from the Mater Natura - Instituto de Estudos Ambientais in Brazil. Like all species in its genus, it is found in a very small strip of Atlantic Forest in the southeastern coast of the country, and has a vibrant colour pattern.[1] The speciation seen in this genus is thought to be a byproduct of the rift between the valley versus mountain terrain and its particular microclimates, to which they are adapted. It might be in population decline due to habitat loss.[2] Its name derives from the Latinolivaceus, "olive-colored", in reference to its coloration.
It is distinguished from other cogenerate species by having a robust body, bufoniform, with an adult length between 9.4 and 12.9 millimetres (0.37 and 0.51 in); a rough dorsum, and its general coloration being predominantly dark-green to brown. The skin on its dorsum shows no dermal co-ossification. Its rugose body is similar to that of B. mariaeterezae (as opposed to the smooth dorsum of other species such as B. izecksohni or B. pernix. Its predominantly dark-green dorsum is distinct from all other Brachycephalus species. The species does not present dermal co-ossification characteristic of species within the phippium group, while its bufoniform shape and larger body size means it is rather larger than those in the didactylus group, averaging a length of between 8 and 10 millimetres (0.31 and 0.39 in) and in turn having leptodactyliform body shape.[1]
DistributionEdit
Brachycephalus olivaceus is known only from two localities, which are the base of the Serra Queimada and Castelo dos Bugres, a notable rock formation in the northeastern State of Santa Catarina.[1]
