The fleas (Siphonaptera) of South Carolina with an assessment of their vectorial importance

We document 25 species of fleas from South Carolina including new state records for two species, the ctenophthalmids Epitedia cavernicola and Rhadinopsylla orama. Host and other collection data, by county, are provided, including many new records amassed from 1992-1998 and some older records gleaned from the Clemson University Arthropod Collection. One flea species, the rhopalopsyllid Polygenis gwyni, is especially common and widespread in South Carolina, particularly on the cotton rat (Sigmodon hispidus) in coastal plain habitats. The largest number of flea species (8) from a single host species was recorded from the cotton mouse, Peromyscus gossypinus. Several flea species of potential medical or veterinary importance were recorded, some of which are potential vectors of pathogens, such as the agents of murine typhus, murine typhus-like disease, sylvatic epidemic typhus, cat scratch disease, and rodent bartonellosis. A host-flea list for South Carolina is included.
