ABSTRACT

BackgroundThe caprellid fauna from different localities along the Mexican Pacific coast: Sinaloa (3), Nayarit (15), Jalisco (9) and Colima (1) are presented herein.MethodsA total of 1,093 specimens associated with diverse substrates (octocorals, hydroids, algae, coral rubble and sponge) were recorded.ResultsEight species in four genera were identified: Aciconula acanthosoma Chess 1989; Caprella mendax Mayer 1903; Caprella pitu Sánchez-Moyano, García-Ascencio and Guerra-García 2014; Caprella suprapiscis Galván-Villa and Ayón-Parente 2015; Paracaprella carballoi Sánchez-Moyano, García-Ascencio and Guerra-García 2014; Paracaprella isabelae Sánchez-Moyano, García-Ascencio and Guerra-García 2014; Paracaprella pusilla Mayer 1890; and Liropus isabelensis Sánchez-Moyano, García-Ascencio and Guerra-García 2014.ConclusionsThe new records increase the known species richness in the region at local level, including extensions of the known ranges for all the species. These results highlight the need for a large scale survey along the Mexican Pacific coast, along with a more thorough sampling on a large number of substrata, in order to increase the knowledge of caprellid diversity in the area.
