| Abstract |
The gammaridean family Ampithoidae of the boreal eastern Pacific coastal region (Alaska to Pt.
Conception, California) is examined on a taxonomic, biogeographical and ecological basis. Keyed and described are fifteen species within the genera Cymadusa Savigny, Ampithoe (Leach, sens, str.) and Peramphithoe n.gen. This latter genus is erected for all species of Ampithoe bearing a transverse first gnathopod. Ampithoe dalli Shoemaker is reinstated as a species distinct from A. simulans Alderman. Ampithoe sectimanus n. sp., earlier confused as a variant oi A. pollex Kunkel and A. simulans Alderman, is recognized as a distinct new species. The taxonomic status of Peramphithoe mea (Gurjanova), P. tea (Barnard), P. plea (Barnard) and P. annenkovae (Gurjanova) is clarified. For comparison, two anti-boreal eastern Pacific species, Peramphithoe lessoniophila n.sp. and P. femorata (Krtz^yer) are described. Thirteen of the fifteen North Pacific species are endemic to the boreal region and eight of these are restricted to the North American coast. Greatest diversity occurs on the central and Vancouver Island coasts (12 species) of British Columbia, pointing to this region as being the centre of distribution in the North-eastern Pacific. |
