Parathelphusa maindroni

Unknown

Overview

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

Parathelphusa maindroni faces severe pressure from habitat degradation as freshwater systems across its range experience pollution from agricultural runoff and urban development. Dam construction and water extraction for irrigation have altered natural flow regimes in the streams and rivers this species depends upon. Collection for local consumption and the aquarium trade has further reduced wild populations, particularly in accessible areas near human settlements.
