Etymology: amplamala: Name from Latin 'ampla' meaning enlarged and 'mala' for jaw; referring to the longjaw and expanded infraorbital and preoperculomandibular canals of the species; noun in apposition.

Morphology | Morphometrics
soft rays: 7 - 9. Diagnosis: Distinguished from other cyprinids except Notropis buccatus by having a modified infraorbital and preoperculomandibular canals. It differs from N. buccatus by possessing longer gill rakers (length to width average 2.2, 4.8-2.5 vs. 1.0, 0.8-1.4), absence of breast squamation (vs. with scales), and possessing 5 infraorbital ossicles (vs. 4) (Ref. 57709).
North America: USA. This new species is described for the former southern populations of Notropis buccatus.
The species occurs in small schools, often in clear, shallow (up to 50 cm) streams in slow to moderate runs; prefers sandy to sand mixed with gravel substrates (Ref. 57709).
