The genus Critomolgus Humes and Stock, 1983 represents a group of 34 species of copepods associated with marine invertebrates. Most of these species have been collected in associations with species of the phyla Cnidaria and Echinodermata in several localities in the Indian, Pacific and Atlantic Oceans with three species reported in the Mediterranean Sea. This is the first occasion in which a species belonging to the genus Critomolgus and the family Rhynchomolgidae Humes and Stock, 1972 is recorded for the Gulf of Mexico. Here, we describe a new species of marine copepod, Critomolgus walteri Varela, Price, Middlebrooks et Ambrosio, associated with the octocorals Leptogorgia virgulata (Lamarck, 1815) and L. hebes Verrill, 1869 in 3.3 meters of water in Tampa Bay, Florida. This species possesses characters that unite it with other members of the genus; however, it differs from all other species due to the body length and unique leg 5 and maxilla l characters. This new species provides evidence that much diversity remains to be discovered in the waters of the Gulf of Mexico and future sampling efforts should target this region.
