Eastern Woodrat, Neotoma floridana, Texas Deermouse, Peromyscus attwateri, Arkansas, Ectoparasites, Endoparasites


In Arkansas, the Texas deermouse (Peromyscus attwateri) occurs in the western part of the state where it is restricted to the uplands of the Interior Highlands. The eastern woodrat (Neotoma floridana) is found statewide but is less common in the Gulf Coastal Plain. Very little is known about the parasites of either rodent in Arkansas, especially helminths from P. attwateri at any locality within its range. Found in/on P. attwateri were a coccidian (Eimeria langbarteli), a tapeworm (Catenotaenia peromysci), a nematode (Syphacia peromysci), 2 ticks (Dermacenter variabilis and Ixodes scapularis), and 2 mites (Androlaelaps fahrenholzi and Leptotrombidium peromysci). Eastern woodrats harbored 3 nematodes (Eucoelus sp., Longistriata neotoma, and Trichurus neotomae), a larval bot fly (Cuterebra americana), and a flea (Orchopeas pennsylvanicus). We document 6 new host and 5 new distributional records for these parasites.
