An Electrophoretic Analysis of Necturus from the Southeastern United States

A starch gel electrophoretic analysis of 19 loci in samples from five species of Necturus was conducted to clarify several taxonomic problems. There are two major clades in the genus; seven synapomorphies separate the N. lewisi-N. punctatus clade from that containing N. maculosus, N. beyeri, and N....

Zusammenfassung:	A starch gel electrophoretic analysis of 19 loci in samples from five species of Necturus was conducted to clarify several taxonomic problems. There are two major clades in the genus; seven synapomorphies separate the N. lewisi-N. punctatus clade from that containing N. maculosus, N. beyeri, and N. alabamensis. Within the latter, five synapomorphies distinguish N. maculosus from the remaining taxa. Necturus beyeri and N. alabamensis are genetically distinct and should be considered separate species. We suggest that N. alabamensis, as presently constituted, may represent more than one species.
