Pseudocurimata boehlkei

Local name: Nayón

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Pseudocurimata boehlkei faces significant pressure from habitat degradation in the Magdalena River basin, where deforestation and agricultural expansion have altered riparian zones critical for spawning. Dam construction and water diversions have modified natural flow regimes, disrupting seasonal migration patterns essential for reproduction. Water pollution from agricultural runoff and urban discharge further compromises water quality in the species' limited range.
