(Herrings, shads, sardines, menhadens) > Incertae sedis
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).
