Etymology: Notropis: A misnomer given by Rafinesque to shriveled specimens, with the meaning of "back keel"; from Greek, noton = back (Ref. 45335); buccatus: From the words Eri, an intensifying prefix; cymba, meaning cavity; and buccata, cheek (Ref. 10294). More on author: Cope.
This species is placed in the genus Ericymba in Eschmeyer (CofF ver. Jan. 2012: Ref. 89336).
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic. Temperate; 43°N - 31°N
North America: Mississippi River, Ohio River, and Atlantic coastal tributaries north of the Cumberland River from Missouri to Virginia and Maryland.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 9.8 cm TL male/unsexed; (Ref. 5723); common length : 3.8 cm TL male/unsexed; (Ref. 12193); max. reported age: 3.00 years (Ref. 12193)
Inhabit shallow sandy riffles and raceways of creeks and small to medium rivers (Ref. 3814, 10294). Young and adult feed mainly on entomostracans (cladocerans, copepods, and ostracods); with adults also consuming increasing numbers of midge larvae (chironomids) at night. Life span, 3-4 years; sexual maturity reached in the second or late in the first summer of its life. Two spawning peaks, older individuals in the mid-spring spawning and the preceding year's young during the July spawning (Ref. 10294).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00794 (0.00386 - 0.01635), b=3.12 (2.95 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.1 ±0.30 se; based on food items.
Generation time: 1.2 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (K=0.89; tmax=3).
Vulnerability (Ref. 59153
): Low vulnerability (15 of 100) .
