  1. Genotypes labelled only with a number are identical to those identified in previous studies. Those labelled ‘U.K.’ were new to this study. Genotypes with code numbers <103 were found previously in southern U.K. (Sunnucks et al, 1997), while those with numbers >102 were first recorded in France (Simon et al, 1999). Unique genotypes were unique in the sense that they were found once only in the collections here and in Llewellyn et al (2003), although some of them had been found in the previous studies. G=total number of multilocus genotypes (clones) in the sample; N=sample size; k=genotypic diversity (G/N); H=Shannon–Weaver diversity index; eH=exponential of Shannon–Weaver diversity index.
