This species from eastern Brazil has been recorded from Itabuna and Ilhéus in the state of Bahia, and from Linhares in the state of Espirito Santo. It presumably occurs in intervening areas between these sites, although the limits of its distribution are still very poorly known. It occurs up to 50m asl.
Habitat and Ecology
This species lives in or near ponds on the forest edge, always staying close to water, and is sometimes found on vegetation near water. The eggs are laid on leaves above temporary or permanent ponds, into which the larvae fall and develop.
There is very little information on its population status as there have been very few records.
The major threats to this species are probably related to habitat loss due to agricultural development, wood plantations, livestock grazing, logging, and human settlement.
In Itabuna it occurs in a research station run by CEPLAC, the Comissão Executiva do Plano da Lavoura Cacaueira (the Executive Commission of the Cacaueira Farming Plan), which operates under the auspices of the Brazilian Government Ministry for Agriculture, Cattle Breeding and Supply. This species is also found at the Estação Experimental in Linhares, run by EMBRAPA, which is the Agricultural Research Corporation of the Brazilian Government Ministry for Agriculture, Cattle Breeding and Supply.
This species is similar to Sphaenorhynchus prasinus, according to the original description.
