Una nueva especie de Pagurus (Crustacea: Decapoda: Paguridae), nuevos registros y redescripción de cangrejos ermitaños para el Pacífico mexicano

New records are provided for three species of little-known pagurids. All the material reported was collected by the R/V “El Puma” in the central Gulf of California during the GUAYTEC II cruise. New material is reported for Iridopagurus haigae García-Gómez, 1983, Enallopagurus spinicarpus (Glassell, 1937), and Solenopagurus diomedeae (Faxon, 1893), and these two latter species are redescribed. A new species of hermit crab of the genus Pagurus Fabricius, 1775, is described and illustrated in detail. Among the eastern Pacific species of Pagurus, this new species resembles Pagurus meloi Lemaitre and Cruz Castaño, 2004, P. imarpe Haig, 1974 and P. delsolari Haig, 1974, but differs from these three species in the armature and setation of the chelipeds and second and third pereopods, the shape and armature of the telson, and the number of rows of scales on pereopodal rasp and the presence of a preungual process.Se proporcionan nuevos registros de tres especies de paguridos poco conocidos, Iridopagurus haigae García-Gómez, 1983, Enallopagurus spinicarpus (Glassell, 1937) y Solenopagurus diomedeae (Faxon, 1893) recolectados durante el crucero GUAYTEC II abordo del B/O “El Puma” en el golfo de California central; además se proporciona una redescripción para las dos últimas especies. Se describe e ilustra en detalle una nueva especie de Pagurus Fabricius, 1775. La nueva especie de Pagurus presenta similaridad con Pagurus meloi Lemaitre and Cruz Castaño, 2004, P. imarpe Haig, 1974 y P. delsolari Haig, 1974, pero se diferencia de estas últimas por la armadura y la setación de los quelípedos y los pies ambulatorios, la forma y la armadura del telson, y el número de líneas de escamas sobre la raspa propodal y la presencia de un proceso preungual en los cuartos pereiópodos

A new species of <i>Pagurus</i> (Crustacea: Decapoda: Paguridae), new records and a redescription of hermit crabs from the Mexican Pacific

Additional record of Janetogalathea californiensis (Anomura: Galatheidae) from the central Gulf of California, Mexico, with notes on its distribution

Specimens of galatheids Janetogalathea californiensis (Benedict, 1902) were collected in the northern portion of the Central Gulf of California and represent the third record for this species in the area. Illustrations of the material collected in the Gulf of California are provided and some differences are noted when compared to the description of the paralectotypes. Depth range of the species is discussed and set at 87-786 m. The presence of a wide and deep Oxygen Minimum Zone in the area is believed to limit the dispersion of J. californiensis to the south and to deeper water of the gulf
