本文记述了三个新种Parafilitanais miciana、ColletTee delagata和Paragathotanais medius，分布于墨西哥湾的深海海域。除具多足类外，雄性与雌性的差异不明显。雄性Paragathotanais表明，口器表现出一定程度的性别二型性。所有3个物种的雄性都有功能齐全的口器。讨论了雄性Tanaidacea的鉴定问题。上颌骨上的末端棘状毛的数量被认为是无效的诊断特征。文中还提供了Parafilitanais和Paragathotanais种的检索表。《海湾和加勒比研究》2002年第14卷53-66期稿件于2001年8月3日收到；2002年1月10日接受
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.
