A new species of the deepwater pandalid shrimp of the genus Pandalopsis (Crustacea: Decapoda: Pandalidae) from the Kuril Islands, North Pacific

Abstract

A new species of the pandalid shrimp genus Pandalopsis is reported from the Kuril Islands. Pandalopsis spinosior new species is closely related to P. miyakei Hayashi, 1986, particularly in the rostral formula and the spine arrangement of the ambulatory legs. However, the new species is immediately distinguished from the latter by having the anteriormost spine of the dorsal rostral series (except subapical ones) situated anterior to the antennular peduncle, the pleuron of the fourth abdominal somite with a posteroventral spine and the telson armed with a greater number of dorsolateral spines.
