Abstract

Plesionika sanctaecatalinae: a new species of deep-sea shrimp from the eastern Pacific (Caridea: Pandalidae) by Mary K. Wicksten. Bull. Southern California Acad. Sci., 82(3):138-143, 1983. Plesionika sanctaecatalinae n. sp. is the only mesopelagic pandalid shrimp known off southern California. The species ranges from southern California to Peru at depths of 812-3877 m. It resembles P. gracilis, but can be distinguished from that species by its fewer dorsal rostral spinules and its 15-18 segments in the carpus of the second pereopod.
