Pandalid shrimps (crustacea: Decapoda: Caridea: Pandalidae) collected during the TALUD XIV cruise in the Gulf of California, Mexico, and rediscovery of Plesionika carinirostris Hendrickx, 1989

摘要

Five species of Pandalidae were collected during sampling operations aboard the R/V "El Puma" in the northern part of the central Gulf of California, Mexico. Plesionika carinirostris Hendrickx, 1989, a rare species known exclusively from the type locality in the Gulf of California and from southern California, was rediscovered and proved to be abundant and distributed in a much wider area than previously thought. In addition, new distributions limits are provided for the four other species: Heterocarpus vicarius Faxon, 1893, Pantomus affinis Chace, 1937, Plesionika trispinus Squire & Barrágan, 1976, and P sanctaecatalinae Wicksten, 1983. With an estimated biomass of 123 kg.ha ~(-1), this is the largest capture of H. vicarius ever reported for Pacific Mexico. Samples obtained during this cruise also allow for the largest sample of P carinirositris (total, 158 specimens), and the second largest sample of P trispinus (total, 67 specimens) ever reported for Pacific Mexico.
