Abstract

The Madagascan genus Sauvagella is revised and a new species, Sauvagella robusta, from the Ambomboa River (Sofia drainage) described. Preliminary analysis suggests Sauvagella is an ehiravin and that the pellonuline tribe Ehiravini is monophyletic. The immediate relationships of Sauvagella appear to lie with the single other ehiravin genus from Madagascan waters, Spratellomorpha. Reports of the occurrence of Gilchristella in Madagascan waters are in error.
