Etymology:

Issue
The species in the genera Spratelloides Bleeker, 1851 and Jenkinsia Jordan & Evermann, 1896 should most probably be assigned to a separated family from Clupeidae and Dussumieriidae (Lavoué, pers. comm., July 2013). See a preliminary analysis in Lavoué et al. (2013: Ref. 93878).

No teeth on pre-maxillae, 1 supra-maxilla; W-shaped pelvic scute; isthmus with distinct blunt `shoulders' anteriorly; vertebrae 38 (one fish); silver lateral band not fading away anteriorly.
