Three species in Florida were introduced from Southeast Asia. Nuclear whorl 0.29-0.33 mm in diameter. They're different than the ones found previously. They are variable in their shell characteristics, and some samples may be difficult to identify. (Thompson, 1968). Ovate Campeloma Two genera of North American freshwater snails: Marstonia Baker, 1926 resureected to generic status, and Floridobia, new genus (Prosobranchia, Hydrobiidae, Nymphophilinae). The specie prefer quite clear water, of lakes and backwaters of streams andsprings. The International Commision on Zoological Nomenclature has ruled that AMPULLARIIDAE is the valid name for this family of snails. Biomphalaria havanensis Tarebia granifera 72-74). Fighting a new infestation of an invasive, crop-damaging snail, Florida agriculture officials on Thursday said they have collected 1,000 of the creatures in just over a week in Pasco County, where they were recently discovered following two years in abeyance. The deterioration process is not reversible. The latter are placed in a small container filled with pond water. Black-crested Elimia) Elimia albanyensis (Lea, 1864).

The species of snail was present in Florida in the 1960s and 1970s before being eradicated in 1975, the FDACS said. Overshadowing this genetic divergence are frequent examples of convergent evolution of similar adult shell characters among distantly related species.

Since then a great amount of fieldwork has taken place throughout Florida, and many additions to the fauna have come to light. Carib Fossaria Subspecies bear the same name as the nominate subspecies, as is consistent with the standard used by the American Fisheries Society for fishes, and by other societies for other classes of animals.
