Short description

Dorsal spines (total): 0; Dorsal soft rays (total): 13 - 16; Anal spines: 0; Anal soft rays: 17 - 19; Vertebrae: 41 - 43. Body a little compressed, belly rounded, without pre-pelvic scutes, but a pelvic scute present with slender vertical arms. Gill rakers probably few. Last two anal fin rays not separate from others (cf. Spratellomorpha bianalis). Distinguished from other non-scuted clupeids in area (Spratelloides, Dussumieria, Etrumeus) by presence of normal pelvic scute (cf. W-shaped) (Ref. 188). Body depth 15.8-21.1% SL. Snout 26.2-33.7% HL (Ref. 33664). Scales are cycloid and easily shed (Ref. 56161). Two color forms, yellow and red or orange, have been noted in Sauvagella madagascariensis (Ref. 56161).

Occurs in fresh and brackish water habitats in mid and lower reaches of eastern coastal rivers and Pangalanes Canal network (Ref. 33664).
