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

From: Descriptions of Mikrocytos veneroïdes n. sp. and Mikrocytos donaxi n. sp. (Ascetosporea: Mikrocytida: Mikrocytiidae), detected during important mortality events of the wedge clam Donax trunculus Linnaeus (Veneroida: Donacidae), in France between 2008 and 2011
