Table 3 Estimates of evolutionary divergence (in %) over sequence pairs within the new species of Mikrocytos (for partial 18S only) and between the Mikrocytos spp. The number of base substitutions per site obtained by averaging over all sequence pairs between groups is shown ± the standard error. Alignment length is specified for each gene region analysed
