Title

A new species of Dynoides Barnard, 1914 (Crustacea, Isopoda, Sphaeromatidae) from Canada, with notes on geographic distribution of the north-eastern Pacific Ocean species

Abstract

Dynoides canadensis sp. nov. is described from the south-western coast of British Columbia, Canada. This species differs from its closely related species, D. elegans (Boone, 1923) ), by the presence of a smooth pleotelson without prominent rounded tubercle on the basal part of the pleotelsonic sinus, its sinus wall lacking crenulation; in having the penial processes length 7.7 × basal width and acute distal apex instead of 2.3 × basal width and rounded and blunt distal apex in D. elegans. This new species also has an appendix masculina with the distal apex extending somewhat beyond its base, instead of not reaching the base as is the case for D. elegans. A map of the distribution for the north-eastern Pacific species of Dynoides Barnard, 1914 (D. elegans (Boone, 1921); D. crenulatus and D. saldanai Carvacho & Haasmann, 1984; and D. dentisinus Shen 1929) in the north-eastern Pacific is provided. The new species is abundant in the western coastal zone of British Columbia. A revised generic diagnosis is provided for the genus Dynoides.
