Parsimony haplotype network for (A) 37 Parvulastra exigua and (B) 7 Parvulastra dyscrita specimens. Circle size relates to the frequency of each haplotype, with color indicating origin of the individuals. Smallest circles represent one individual and one haplotype. Extinct or not sampled haplotypes are marked by a blue dot and each line represents one mutational step.
