Relevant Information:

Habitat: This species is so far known only from its type locality in the Jequetepeque River, just to the west of Chilete (Cajamarca and La Libertad) in the Peruvian Amazon (Silfvergrip 1996, Ortega et al. 2012, Bockmann 2003). Its area of occupancy (AOO) has been estimated to be 9 km² (using a 3 x 3 km grid cell). The species occurs in only one location, based on the current major threats affecting it (habitat modification and pollution). Diet: It feeds on insect larvae, crustaceans and small fishes (Galvis et al. 2006). Remarks: This species has a very restricted distribution (AOO = 9 km²) and occurs in only one location in northern Peru. The quality of the habitat is declining due to water pollution from urban areas and mining, the presence of a dam that leads to changes in water levels, and micro-habitat destruction due to channelling of the river. It is therefore listed as Critically Endangered (IUCN 2016).
