| Abstract: | A population-genetic study of females of T. lineola from New Jersey and Louisiana determined that the coastal and inland "varieties" T. lineola hinellus and T. lineola lineola are reproductively isolated and represent distinct species. Diagnostic differences were found at 4 of 11 gene loci surveyed. Nine individuals were genetically distinct from all other specimens and may represent a 3rd cryptic species. Stepwise discriminant analysis was used to produce a taxonomic key for separation of the coastal and inland species based on 4 easily measured morphological characters. The degree of separation achieved was greater for specimens collected in Louisiana. |
