First survey of arthropod gut fungi and associates from Vieques, Puerto Rico.

This is the first survey of trichomycetes for Vieques, Puerto Rico. Several types of arthropods, including millipedes, crabs, mosquitoes, bloodworms, amphipods and isopods, were collected from marine, freshwater and terrestrial habitats and their guts examined for the presence of trichomycetes. A new species of Enterobryus, which was found attached to the gut of the millipede Anadenobolus arboreus (Diplopoda), is described as Enterobryus viequensis sp. nov. We report the presence of Smittium culisetae in mosquito larvae and also provide information on two eccrinids associated with the fiddler crabs Uca rapax and U. burgersi and an amphipod.
