The specimens with the number "1" are from Camocim beach (Ceará State, NE Brazil) and those with numbers "2", "3", and "4" are from Barra Grande beach (Piauí State, NE Brazil). The numbered specimens of N. virginea (1, 2, 3, and 4) and N. meleagris (1, 2, 3, and 4) are the same specimens used in the phylogenetic analysis of Figure 1. Scale bars: 1.0 mm (A–L); 100 μm (M, N).

Figure 2 Statistical parsimony network analysis (TCS algorithm) based on 64 partial mitochondrial COI sequences (347 bp). This analysis included specimens of Neritina meleagris and Neritina virginea from the Caribbean and Brazilian Provinces. Size of the circle is proportional to frequency of the haplotype and colours inside the circles designate geographical locations to which the samples belong. Black circles correspond to hypothetical haplotypes. The number of mutational steps is indicated by dashes on branches. We highlighted the 36 mutational steps that separate the two species haplotypes.

Figure 1 Molecular phylogenetic hypothesis (Bayesian tree) of some species of Neritidae of the Western Atlantic. The Bayesian tree was based on partial mitochondrial COI and 16S sequences. The Neritina meleagris and Neritina virginea clades (ingroup) are highlighted. The other taxa were used as outgroup. Numbers on and below the main branches represent the posterior Bayesian probabilities (BP) (>0.90) and bootstrap values for maximum likelihood (ML) (>70%), respectively. Specimens with the number "1" are from Camocim beach (Ceará State, NE Brazil) and those with numbers "2", "3", and "4" are from Barra Grande beach (Piauí State, NE Brazil). The numbered specimens of N. virginea (1, 2, 3, and 4) and N. meleagris (1, 2, 3, and 4) are the same specimens shown in Figure 3.
