Barbouria yanezi sp. nov., a new species of cave shrimp (Decapoda, Barbouriidae) from Cozumel Island, Mexico

A new species of the genus Barbouria from Cozumel Island, Mexico, is described. The new species, Barbouria yanezi is similar to Barbouria cubensis in exhibiting a cornea narrower than the eyestalk, and in its telson ornamentation, but differs from the latter species in the number of rostral spines, the proportions of the scaphocerite, the relative proportions of the carpus and propodus of the first and second pereiopods, the relationship between the appendices masculina and interna, and in size: it is larger than B. cubensis. The geographical relationship between the species is discussed.
