A new species of the caridean shrimp genus Ogyrides Stebbing, 1914 (Decapoda: Ogyrididae) from the eastern tropical Pacific

The caridean shrimp Ogyrides wickstenae sp. nov. is described from Mazatlan, Pacific coast of Mexico. The new species is most closely related to O. tarazonai Wicksten & Mendez, 1988 and O. hayi Williams, 1981, sharing with them a single spine on the dorsal midline of the carapace. However, the new species can be distinguished from the two allied species by the presence of a single small spine on the second endopodal segment of the third maxilliped and the five-segmented carpus of the second pereopod. A key for the Eastern Pacific species of Ogyrides is provided.
