Two North American genera and seven species:

Neotridactylus - one sp. widespread (apicialis), another sp. restricted to FL (archboldi)

Ellipes - one sp. widespread (minuta), another sp. restricted to FL (eisneri); three more spp. in the West (californicus, gurneyi, monticolus)
less than 10 mm
Small orthopterans, rather flattened, so resemble crickets, though more closely-related to grasshoppers. Usually living near bodies of water, they are able to swim well. Characteristics:
hind femora enlarged (used for jumping), flattened (apparently for use in swimming)
front and middle tarsi with two segments, rear with three (tarsal formula 2-2-3)
Typically sandy margins of ponds, ditches, streams. The FL endemic species are found in upland sandy ridges.
