Identical letters indicate populations with a comparable average number of scales. Nb, number of individuals examined; sd, standard deviation; min, minimum number of scales; max, maximum number of scales; Aaa, homogeneous family Ae. aegypti aegypti; Aaf, homogeneous family Ae. aegypti formosus; Aaf + Aaa, heterogeneous family.
