Specimens of the pycnogonid genus Endeis from Mumbles Point (southern Wales) were found to differ consistently in certain morphological features when compared with samples from Martin's Haven (southwestern Wales). The use of biochemical genetic techniques to compare enzyme loci showed the samples from the two localities to have no common allele at 11 of 15 loci examined. Genetic identity and genetic distance between the two samples were 0.241 and 1.42, respectively. Such high levels of genetic differentiation between the two morphs not only indicate that they are not conspecific but also suggest that they possibly should not be congeneric. It is concluded that there are at least two species of Endeis in Britain and that the valid names for these are E. charybdaea (Dohrn) and E. spinosa (Montagu)
