It is known to live in Atlantic drainages from New York to South Carolina. It may have been introduced to the New River system in Virginia, although it is possible that it is native there.[3] It may have spread via canals into tributaries of Lake Ontario.[3] It is often found near plants.

Taxonomy
There are two subspecies of swallowtail shiner:[4] Miniellus procne procne[5] and M. procne longiceps (Cope, 1868).[6] The nominate subspecies is found in the Delaware River and Susquehanna Rivers south to the James River in Virginia. M. procne longiceps is found from the Roanoke River in Virginia to the Santee River in South Carolina.[7]
This species is the type species of the genus Miniellus, which was originally proposed as a subgenus of the genus Notropis,[8] but is now regarded as a valid genus, within the subfamily Pogonichthyinae in the family Leuciscidae.[1]
