F. The Gammarus duebenii group

Here we have combined G. duebenii and Marinogammarus finmarchicus , both somewhat odd man out in their genus, both morphologically and ecologically. Both are largely intertidal species, although duebenii has a much wider ecological tolerance, and both have an amphi-atlantic distribution. ( Pinkster et al. (1970) split off the freshwater populations in Ireland and Brittany as G. d. celticus; this taxon is not considered here). In contradistinction to the species in the zaddachi and tigrinus groups, these species are not patterned, but unicoloured.
