     David Lindberg had now reduced our local limpet groupings to Acmaeidae and Lottiidae.  Recent molecular techniques in identification has made it apparent that the previous characters used to delineate between generic groupings were flawed.  He now has chosen to adopt a more conservative approach to limpet nomenclature.


Acmaea funiculata Carpenter, 1864 (=Niveotectura funiculata)


All previous genus names of Collisella, Discurria, Macclintockia, Notoacmea, and Tectura now become Lottia, with the species name remaining the same.  The following listings contain additional changes.

Littorina sitkana Philippi, 1846 [=L. kurila Middendorff, 1848; =L. atkana (Dall, 1886)]  Only clearly distinguished from barnacle ecotype of L. subrotundata since 1991.

Mytilus trossulus Gould, 1851; M. galloprovincialis Lamarck, 1891; M. edulis Linnaeus, 1758. Genetic studies have shown that the native smooth mussel in the North Pacific is M.trossulus, which occurs from the Arctic south to central California, where it now forms a hybrid zone with the introduced European M. galloprovincialis; the latter occurs from central California to Baja California; wild specimens of M. galloprovincialis have also been found in southern British Columbia, but establishment there is uncertain. The native North Atlantic M. edulis is subject to experimental mariculture in British Columbia and may spread and hybridize as well. Members of this complex are widespread; abundant on wharf pilings, floats, docks, rocks; occasional on outer coast.
