Proceratophrys melanopogon is a species of frog in the Odontophrynidae family. It is endemic to Brazil. Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical moist montane forests, rivers, and intermittent rivers. It is threatened by habitat loss.
Description
Proceratophrys melanopogon grows to a snout-to-vent length of 36 to 50 mm (1.4 to 2.0 in) for males and 41 to 62 mm (1.6 to 2.4 in) for females. It has a rounded snout and the fingers are unwebbed and have swollen tips. The skin on the back is smooth or has small warty tubercles and on the side has glandular warts. There is a distinctive ridge running from above the eye to the pelvis. The colour is some shade of brown and there are several irregular dark blotches.[2]
Distribution and habitat
Proceratophrys melanopogon is endemic to the states of Minas Gerais, São Paulo and Rio de Janeiro in eastern Brazil. It is found in forests, living among the leaf litter and breeding in small streams. Its altitudinal range is 800 to 1,480 metres (2,620 to 4,860 ft) above sea level.[2]
Breeding
Proceratophrys melanopogon is an explosive breeder. After heavy rain has fallen creating temporary pools and streamlets, large numbers of male frogs gather together and call to attract females.[3] The call is a multipulsed series of notes with a frequency of about 1179 Hz and is heard between 6pm and midnight. The tadpoles develop in slow-moving streams.[2]
Status
The total range of Proceratophrys melanopogon is probably less than 20,000 square kilometres (7,700 sq mi) but the primary and old secondary forest it inhabits does not seem to be significantly threatened by tourism and human development, and part of it is in national parks or in otherwise protected areas. This frog is quite common and though its numbers may be decreasing, they are not doing so at a fast enough rate as to make the species threatened, and the IUCN lists it as being of "least concern".[1]
