Title:A Hypomaxillary Bone in Harengula (Pisces: Clupeidae)

Abstract:The herring genus Harengula Valenciennes
(as herein restricted) contains five bilateral
pairs of bones in the upper jaw (Fig. 1A) .
Most other clupeid fishes contain three or four
such pairs of bones: premaxillary, maxillary,
and one or two supramaxillaries. The extra pair
of bones in Harengula is here termed the hypomaxillary.
The hypomaxillary also occurs in the
clupeid genera Pliosteostoma Norman and Pellona
Valenciennes, and its presence has been
used to distinguish these two genera from other
genera. The presence of the hypomaxillary in
Harengula and its usefulness as a taxonomic
character in separating Harengula from other
closely related genera previously has been overlooked.
