Ptychochromis curvidens Stiassny & Sparks, 2006

Original description as Ptychochromis curvidens:


  • Stiassny, Melanie & John S. Sparks. 2006. "Phylogeny and Taxonomic Revision of the Endemic Malagasy Genus Ptychochromis (Teleostei: Cichlidae), with the Description of Five New Species and a Diagnosis for Katria, New Genus". American Museum Novitates. (n. 3535); pp. 1–55 (crc01327) (abstract)

Conservation: Ptychochromis curvidens is evaluated by the international union for the conservation of nature in the iucn red list of threatened species as (DD) data deficient (2017). According to Patrick de Rham (in litt.), the conservation status of Ptychochromis curvidens is difficult to assess. The species is not abundant anywhere within its range and exotic fishes, especially Oreochromis sp., are present in the region. However, several other native species persist in reasonable numbers and exotic species are not abundant, suggesting that the ecosystem remains relatively healthy. This is further indicated by a diverse aquatic flora recorded at many sample sites, where endemic plant species such as Aponogeton cf. bovinianus remain plentiful. Human populations in these remote and poorly accessible regions remain small, and fishing pressure is consequently also low (Stiassny et al., 2006).
