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.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; pelagic; depth range 0 - 1 m (Ref. 57709). Tropical
North America: USA. This new species is described for the former southern populations of Notropis buccatus.

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).
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).
