ORTIZ, Manuel; WINFIELC, Ignacio e CHAZARO-OLVERA, Sergio. Updated checklist and illustrated key to mysid (Crustacea, Peracarida) genera from the Intra-American Sea. Rev. Mex. Biodiv. [online]. 2012, vol.83, n.4, pp.983-1003. ISSN 2007-8706. https://doi.org/10.7550/rmb.27139.
An updated checklist and an illustrated key for the identification of the 38 genera of marine, estuarine and stygobitic opossum shrimps recorded from the Intra-American Sea, are presented. These crustaceans were included in 6 families, 5 subfamilies, and 5 tribes, into the suborders Lophogastrida and Mysida. First order grouped 5 genera and the second 33. Of these genera, 35 live in marine and estuarine environments, 2 are stygobitic and another, Antromysis, is distributed in each one. The genera Anchialina, Siriella, Mysidopsis, Mysidium and Heteromysis have a wide distribution in overall Intra-American Sea, instead of Chalaraspidum, Euchaetomera, Eucopia, Gironomysis, Metamblyops, Mysidella, Palaumysis, Platymysis, Pleurerythrops, Pseudomma and Synerythrops with a restricted geographical distribution. The Caribbean Sea and the Gulf of Mexico constitute the regions with the biggest number of mysids genera.
