This study is the first report of benthic amphipods for a new line of research in this area of the Mexican Pacific. We analyze the first records of amphipods in spiny lobster (Panulirus spp) pueruli collectors in Cospita bay, Gulf of California, Mexico. The organisms were obtained collectors that simulate seaweed that present cavities as refuges. The collectors were submerged to a depth of 1 to 1.5m. 170 benthic amphipods were obtained, distributed in four superfamilies, seven families, seven genera and three species. The most representative genus were Bemlos and Tritella and the most abundant families were Aoridae, Ischyroceridae and Caprellidae. The records of amphipods indicated here represent the basis for the knowledge of this taxonomic group and the artificial collectors are refuge for benthic amphipods in this area.
