Six new amphipod species in the genus Leucothoe from the tropical western Atlantic Ocean are described and illustrated. Extensive field collecting and specialized underwater collecting techniques have documented 43 new invertebrate host records for these new taxa. Four of these new species inhabit interior canals of sponges; Leucothoe barana n.sp., Leucothoe garifunae n.sp., Leucothoe saron n.sp., and Leucothoe ubouhu n.sp. A remarkable new species, Leucothoe flammosa n.sp., nestles in the gills of seven species of bivalve mollusks. A single species, Leucothoe wuriti n.sp., appears restricted to the branchial chamber of two species of solitary ascidians. Detailed illustrations and scanning electron microscopy enables comparison of ultrastructure details. More precise taxonomic character morphologies are also presented thus allowing improved taxonomic precision within the family Leucothoidae.
