Average intra- and interspecific genetic distances (nt) for Lymnaea neotropica and L. viator

Groups analysed	ITS-2	ITS-1	16S	cox1
L. neotropica vs L. viator	15.15 (0.0354)	57.90 (0.1163)	8.56 (0.0202)	35.20 (0.0554)
L. neotropica	1.60 (0.0040)	0 (0)	4.33 (0.0102)	19.61 (0.031)
L. viator	1.39 (0.0035)	0.87 (0.0017)	4.31 (0.0102)	7.53 (0.012)

The number of base differences per site from averaging over all sequence pairs between and within groups are shown. Distances calculated using as substitution model total nucleotide differences (ts + tv) and p-distance (in parentheses) methods. Fewer than 5 % alignment gaps, missing data and ambiguous bases were allowed at any position (all positions with less than 95 % site coverage were eliminated)
