Three closely related species of the recently defined cletodid genus Triathrix Gee & Burgess, 1997 are reported from the southern bight of the Gulf of Mexico. T. mayae sp. nov. is assigned to the genus while, based on the setal morphology of the P1, the new genus Sphingothrix is defined to unify the species S. goldi sp. nov. and S. kalki (Gee & Burgess) comb. nov. The descriptions of S. kalki, S. goldi and T. montagni Gee & Burgess are complemented with observations on their copepodid stages. The particular characteristics of T. nicobarica are discussed in the light of these observations. The development of the rami and the successive addition of elements on the exopodites during copepodid development is found to agree with the scheme proposed by Fiers (1996) for the Cletodidae. Preliminary ecological data on two species from the Bay of Campeche are given.
