Tanaidacea (Crustacea: Peracardia) of the Gulf of Mexico. X. The Question of Being Male
Three new species Parafilitanais mexicana, Collettea elongata, and Paragathotanais medius are described from deep-sea localities in the Gulf of Mexico. The male of Parafilitanais does not vary conspicuously from the female, except for possessing pleopods. Male Paragathotanais reveal that the mouthparts display some degree of sexual dimorphism. Males of all 3 species possess functional mouthparts. The problems identifying male Tanaidacea are discussed. The number of terminal spiniform setae on the maxillule is considered invalid as a diagnostic character. Keys to the species of Parafilitanais and Paragathotanais are given.
