Principal component and canonical variate analyses were used to investigate the variation of twenty characters in 298 females and 207 males of the Onychiurus armatus group from twenty-five samples collected at fourteen sites in England and Wales. These demonstrate the presence of four morphologically distinct groups which are recognized as species.
