The deep-water crangonid Parapontophilus occidentalis (Faxon, 1893) is endemic to the eastern Pacific and has been reported from Mexico to Chile, in depths of 837-4082 m. Material collected off the west coast of the Baja California Peninsula (BCP) during the TALUD XV, XVI and XVI-B cruises consists of a series of 136 specimens (M:F = 1:3.6) with 30 % of ovigerous females. The material examined ...

Phylogenetic relationships among all of the major decapod infraorders have never been estimated using molecular data, while morphological studies produce conflicting results. In the present study, the phylogenetic relationships among the decapod basal suborder Dendrobranchiata and all of the currently recognized decapod infraorders within the suborder Pleocyemata (Caridea, Stenopodidea, Achelat...

A new species of Glyphocrangon has been collected during deep-water sampling off western Mexico, in the east Pacific. The series of specimens, including both males and females, was found between 780 and 1879 m depth. Glyphocrangon sp. nov. is close to G. sicaria Faxon, 1893 and G. vicaria Faxon, 1896, both occurring in the east Pacific. It differs from both species, however, by the absence of t...
