Type locality of the syntypes of Spratelloides madagascariensis, more specifically the holotype of Sauvagella madagascariensis longianalis and the holotype of Sauvagella madagascariensis brevidorsalis: 'Madagascar' (Ref. 42522, 94656). Known from mid and lower reaches of eastern coastal drainages (Ref. 33664, 56151, 56161) and Pangalanes Canal network (Ref. 13296, 33664), from Manajary River in the south to Manamara River in the north (Ref. 33664), including Mangoro River (Ref. 26236), Lake Tampolo (Ref. 33664), Maningory River (Ref. 33664) and Lokoho River (Ref. 33664). More extensive sampling will no doubt extend that range (Ref. 33664). Also reported from Lake Kinkony (Ref. 13296), but its presence in the northwest of Madagascar is unconfirmed (Ref. 33664). Also Ref. 188, 3509, 9391, 13333, 43240, 94656, 117496, 117576.
