A new shrimp species of Plesionika Bate, 1888 with high basal rostral crest (Crustacea: Decapoda: Pandalidae) from Taiwan

Abstract

A new shrimp species of the genus Plesionika Bate, 1888 is described based on specimens collected in deep-water off eastern Taiwan. The new species, P. albocristata, can be readily distinguished from other species of the genus by bearing a high basal rostral crest, having the second pereiopods subequal, and the telson bearing four pairs of dorsolateral spines. A brief discussion on the affinities of this new species is given.
