- First records of non-hyperiid planktonic amphipods (Amphilochidea and Senticaudata) from deep waters of southwestern Gulf of Mexico, with an identification key Marco Violante-Huerta Laura Sanvicente-Añorve Aurora Marrón-Becerra Elia Lemus-Santana César Flores-Coto Biología Mesopelagic zone Pelagic amphipods Stratified sampling Stenopleura atlantica Vertical distribution Within the planktonic Amphipoda, the non-hyperiid species have been scarcely studied in the southern Gulf of Mexico. Zooplankton samples were obtained over a grid of 25 oceanographic stations in the southwestern area of the gulf using a stratified opening-closing plankton net system in epi- and mesopelagic zones (0-1,000 m depth). Sixty-nine individuals of non-hyperiid planktonic amphipods were obtained. Their taxonomic identification indicate the presence of 3 species of Amphilochidea, Cyphocaris anonyx Boeck, 1871, C. challengeri Stebbing, 1888, Eusiropsis riisei Stebbing, 1897, and 1 species of Senticaudata, Stenopleura atlantica Stebbing, 1888, representing the first records of these species in the region. A taxonomic account and information on their horizontal and vertical distribution in the studied area are provided. The presence of eyes in E. riisei is for the first time reported. An identification key for 7 species of Amphilochidea and Senticaudata recorded in the Gulf of Mexico is provided. 2020 artículo científico 1870-3453 https://www.redalyc.org/articulo.oa?id=42571632074 https://www.redalyc.org/journal/425/42571632074/ https://www.redalyc.org/journal/425/42571632074/html/ https://www.redalyc.org/journal/425/42571632074/42571632074.epub https://www.redalyc.org/journal/425/42571632074/movil 10.22201/ib.20078706e.2020.91.2975 en http://www.redalyc.org/revista.oa?id=425 Revista Mexicana de Biodiversidad application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Biodiversidad (México) Vol.91
