Pelagic shrimps (Decapoda: Dendrobranchiata and Caridea) collected during the TALUD XIV cruise in the northern Gulf of California, Mexico

Abstract

A total of six species of pelagic shrimps were collected during the TALUD XIV cruise aboard the R/V "El Puma", in the northern Gulf of California, in April 2011, including two species of Dendrobranchiata [Eusergestes similis (Hansen, 1903) and Sergia phorca (Burkenroad, 1940)], and three species of Caridea [Pasiphaea americana Faxon, 1893, P. emarginata Rathbun 1902, and P. pacifica Rathbun, 1902]. Additional specimens of the previously reported Maryprocessa pippinae (Wicksten & Méndez, 1985) were also found among the samples. Most frequently collected species were P. americana (50% of total) and P. pacifica (36.6%). Most numerous species in the samples were P. pacifica, P. americana and E. similis. Some minor morphological differences not previously recorded in specimens of Pasiphaea pacifica collected elsewhere were detected. These differences might correspond to an intraspecific variation.
