^*vc type data are from Cortesi et al. (15, 17), Bissegger et al. (31), and Table 1. 

^†vic genotypes were determined for EU types by Cortesi and Milgroom (14); “1” and “2” refer to the two alleles found at each vic locus. 

^‡A locus is considered polymorphic if the frequency of the less common allele is >0.05. 

^§Allelic diversity was calculated for each locus according to Nei (36) as ĥ = n (1 − p̂² − q̂²)/(n − 1), where p̂ is the frequency of allele 1, q̂ = 1 − p̂ and n is the sample size. Mean diversity (Ĥ) is the average of ĥ over all six loci. 

^¶Underline indicates allele frequencies not significantly different from 0.5 (α = 0.01).
