Scinax faivovichi is known only from Ilha de Porcos Pequena (23 22' 32.6" S, 44 54' 01.6" W, C.A. Brasileiro pers. comm. 2008), a 24-ha island approximately 0.74 km from the northern coast of São Paulo state, Brazil (Brasileiro et al. 2007). The species occurs between 0-80 m asl (C.A. Brasileiro pers. comm. 2008).
Habitat and Ecology
The species is restricted to the Ilha de Porcos Pequena, a privately-owned island covered by native preserved Atlantic Forest. Males of the species are known to call in the months of April, October, and December, although less so during April. They are nocturnal, calling from bromeliad leaves. Females were also found on bromeliad leaves. Tadpoles were found in bromeliad axils during October and December, suggesting that breeding season coincides with early summer rains in September/October (Brasileiro et al. 2007).
The species is abundant within the island, especially on rainy and hot nights (Brasileiro et al. 2007).
Given its extremely restricted range and habitat specificity, S. faivovichi is believed to be susceptible to extinction because of habitat modification or disturbance (Brasileiro et al. 2007). This modification includes destruction of the species' breeding habitat, bromeliads (C.A. Brasileiro pers. comm. 2008).
The island does not have any legal conservation status under federal laws. In view of its small distribution and the absence of any enforcement, S. faivovichi should be in a threatened IUCN category (Brasileiro et al. 2007).
In the Scinax perpusillus group according to the original publication. Scinax faivovichi is diagnosed by a combination of morphological characters (Brasileiro et al. 2007).
