For each population and locus, observed (Ho) and expected (HE) heterozygosities as well as allelic richness (A) are given. Zero values indicate that the locus is monomorphic in this population. Ranges of allele sizes are given for the entire data set (upper values) and within a single individual (the lower value in parentheses gives the largest observed range). Non-sulfidic surface habitats: AB, Arroyo Bonita, AT, Arroyo Tres, RO, RÍo Oxolotan; sulfidic surface sites: EAI, El Azufre I, EAII, El Azufre II; sulfidic cave (Cueva del Azufre), chambers V, × and XIII. Deviation from HWE after Bonferroni correction (i.e., heterozygote deficiency) are indicated by asterisks, whereby *P < 0.05, ** P < 0.001, and *** P < 0.001.
