A New Species of Notropis (Cypriniformes: Cyprinidae) from the Southeastern United States
 

Summary: A New Species of Notropis (Cypriniformes: Cyprinidae) from the
Southeastern United States
THOMAS P. PERA AND JONATHAN W. ARMBRUSTER
Notropis amplamala, the Longjaw Minnow, is described as a new species for the
southern populations of N. buccatus. Notropis amplamala differs from its sister species,
N. buccatus, by possessing longer gill rakers (length to width ratio average 2.2, 1.82.5
vs. average 1.0, 0.81.4), having no breast squamation (vs. breast with scales), and
possessing five infraorbital ossicles (vs. four). The two species have a disjunct
distribution with N. amplamala occurring in Gulf of Mexico and Atlantic Ocean
tributaries from the Pearl River to the Altamaha River, and N. buccatus occurring in
Mississippi River, Ohio River, and Atlantic coastal tributaries north of the Cumberland
River from eastern Missouri to Virginia and Maryland.
NOTROPIS buccatus (Cope, 1865), the silver-
jaw minnow, is a small cyprinid found
throughout the eastern United States. Notropis
buccatus is a benthic species that prefers moder-
ately flowing streams with bottoms of sand or
sand mixed with fine gravel (Wallace, 1972). The
silverjaw minnow was originally described from
the Kiskiminitas River in western Pennsylvania
