Justification of Red List category
This species qualifies as Critically Endangered as it is endemic to one Andean lake where it has undergone significant population declines, such that an extremely small number of adults remain. Although numbers are known to fluctuate considerably, most probably as a result of extractive pressure combined with relatively unstable climatic conditions linked to ENSO events, with numbers lowest during dry years, recent surveys suggest a continuing rapid population decline.
