This species is widespread in the tropical eastern Pacific, although it is known to be rare in Costa Rica. This species is associated with estuarine environments (which is rare for this genus) and there are some localized threats for this habitat. However, we have no population information and the effects of these threats on this species are unknown. Therefore, it is listed as Data Deficient.
