Bachia trisanale is endemic of western Amazonia , with its eastern distribution restricted to the upper Solimões, Juruá, and Purus river systems, occurring in Brazil , Peru , and Ecuador ( Fig. 3 ). We examined only specimens from Peru and Ecuador ; record from Brazil (state of Acre ) was obtained from Teixeira et al . (2013b). As usual for Bachia , information about its ecology and habitat is scarce. Duellman (1978) found three specimens in a secondary forest; one was dug out of sandy soil; one was found in a trench; other under a rotting log in a clearing.
