Taxonomic Note (written June 2007)
The populations of mudpuppies living in the region between Mobile, Alabama and the Florida panhandle are generally considered to be distinct from both Necturus alabamensis and Necturus beyeri. However, these populations have not yet been officially described. They are named by various sources as Necturus sp. cf. beyeri or Necturus sp. cf. alabamensis. (The term "cf." means "compare to" and is used to indicate an animal that resembles the named species, but may or may not be a member of that species.) In habitat and appearance, they are most closely allied with Necturus beyeri.

Informally, the name Necturus lodingi has been mentioned as a possible name for this population of mudpuppies. The name N. lodingi was formerly the valid name for mudpuppies in this region, with a type locality near Mobile, Alabama. However, until publication of an update to the taxonomy of the Gulf Coast mudpuppies, it is not correct to use this name.
