Abstract

Neomegamphopus hiatus is described from Venezuela and the Florida Keys, N. pachiatus and N. heardi from Pacific Panama, and N. kalanii from eastern Florida. Neomegamphopus hiatus and N. pachiatus differ from a close congener, N. roosevelti (tropical eastern Pacific), in the much larger coxa 1 of mature males, the less setose gnathopods, and the broader carpus of the first gnathopod bearing a much deeper incision defining the posterior tooth; the carpus is much shorter and stouter in N. hiatus and N. pachiatus than in N. roosevelti. Neomegamphopus heardi differs from the other species in the bifid tooth on the carpus of gnathopod I in males. Questions regarding the reclassification ofthe Isaeidae, Aoridae, and Neomegamphopidae are explored and the three families amalgamated again to their status of 1973 (except Corophiidae which is segregated).
