Resumo: | The hydrothermal vent shrimp genus Mirocaris is reviewed. Morphological comparison between the two nominal species in the genus, M. fortunata and M. keldyshi, was made based on the re-examination of the holotype and paratypes of Mirocarisfortunata and the paratypes of M. keldyshi. Samples newly collected from various sites on the Mid-Atlantic Ridge were also examined. The validity of the genus Mirocaris has been confirmed. However, our study has revealed that the supposed morphological characters distinguishing M. fortunata and M. keldyshi do not provide significant taxonomic differences and further comparison failed to detect morphological differences between the two taxa. Thus M. keldyshi is synonymized with M. fortunata, and so there is only one single species in the genus Mirocaris. This supports the suggestion by Shank et al. (1999), based on a molecular study, that the two taxa might be conspecific.   A redescription of M. fortunata is provided to better establish the morphology of the species. The clarification led us to improve the morphological descriptions of the caridean species associated with vent or seep environments and to reassess the relationships among Mirocaris and the other shrimp taxa in the superfamily Bresilioidea. The generic diagnosis of Mirocaris is emended. Because a number of presumably apomorphic characters are shared by Mirocaris and other alvinocaridid genera, the genus Mirocaris is now assigned to the family Alvinocarididae. The family Mirocarididae is synonymized with the Alvinocarididae and the diagnosis of this family is emended.
