Caridean Shrimps of the Gulf of California. I. New Records, with Some Remarks on Amphiamerican Distribution

Abstract

Six caridean shrimps are reported from the Gulf of California, Mexico, for the first time: Ambidexter symmetricus, Latreutes parvulus, and Salmoneus ortmanni were not previously reported in the eastern Pacific; northern range extensions are given for Thor manningi, Ambidexter panamensis, and Automate dolichognatha. A brief discussion on amphiamerican species is included with a comparison of brachyuran crabs and caridean shrimps.
