- Region according to the TDWG standard, not a precise distribution map.
NOTE: TDWG regions are generated automatically from the text in the distribution field and not in every cases it works well. We are working on it.
|Types||Syntypes: ZSI 664 and 1898|
|Comment||Synonymy: GEMEL & PRASCHAG (2003) pointed out that GRAY illustrated A. nigricans already in 1831 although he assigned it to A. hurum (then Trionyx hurum). See their paper also for a more complete synonymy.|
Phylogenetics: According to the molecular data of Engstrom et al. (2004) Aspideretes should be renamed Nilssonia, as Nilssonia (GRAY 1872) has priority over Aspideretes (HAY 1903).
Literature: The paper by ANDERSON is not present in our AMNH collection.
Distribution: possibly in Bhutan (Lenz 2012 and references therein).
Conservation: Nilssonia nigricans has only survived in an artificial temple pond in Bangladesh, but seems to be extinct in nature.
Habitat: freshwater (rivers and tributaries, lakes)
