Red List Category & Criteria: Vulnerable A2ac ver 3.1

Lamprotula rochechouarti is a very restricted species only living in localized sites and restricted to clear water and fast running waters. The inferred reduction is equal or more than 30% population decline due to degradation of the quality of its habitat, which is declining due to water pollution and damming (D. Van Damme pers. comm. 2011). As a result, the population are declining and in the last 10 year it has only be recorded from few location. It is therefore listed as Vunerable A2ac.
