“…Morphological data were extracted from Dornellas et al (2021), except for samples of A. viridulum from the Caribbean (Table S2). The features of the head-foot, esophagus and odontophore muscle were examined, but radulae could not be inspected.…”

“…DeVries (2007) later revised the Late Cenozoic tegulines from southern Peru and elevated the Agathistoma and Chlorostoma Swainson, 1840 to genus level. Two phylogenetic studies aiming to resolve teguline relationships (Table 1) have been conducted using molecular (Hellberg, 1998) and morphological data (Dornellas et al, 2021). The relationships of Tegula s.l.…”

“…inferred from two mitochondrial gene regions (cytochrome c oxidase I [COI] and 12S) recovered Agathistoma as the sister group to Tegula pellisserpentis (Wood, 1828), the type species of Tegula, with a strong support (Hellberg, 1998). Cladistic analysis of the Tegulinae based on external and internal morphological characters (Dornellas et al, 2021) included Tegulinae within the subfamily Turbinidae and also recovered Agathistoma supported by four synapomorphies, albeit with low bootstrap support. Hellberg (1998) concluded that sister species of Tegula often occur along the same coast or even sympatrically, calling to question the need for strong and lasting geographical barriers to form new species.…”

“…In addition to their anti-tropical distributions, A. viridulum and A. hotessierianum are good models to study the biogeographic patterns of the Western Atlantic region. In addition, populations of A. hotessierianum and A. viridulum separated by the tropical gap also show morphological differences in their shells and radulae (Dornellas et al, 2021).…”

Phylogeography of Agathistoma (Turbinidae, Tegulinae) snails in tropical and southwestern Atlantic

The rocky intertidal gastropods Agathistoma viridulum and A. hotessierianum occur from the Caribbean to southern Brazil, with a gap in the equatorial region, giving them an anti-tropical distribution. We used sequences from mitochondrial genes to elucidate the phylogeography of A. viridulum and A. hotessierianum and to infer their relationships to other species of Agathistoma. For A. hotessierianum, haplotype networks and phylogenetic analyses split samples into two distinct groups: one (A. hotessierianum) in the Caribbean region (Greater and Lesser Antilles; Venezuela: Sucre and Isla Margarita) and a new species that we describe from northeastern Brazil. For A. viridulum, genetic analyses split the samples into three groups (Caribbean, northeastern Brazil and southeastern Brazil), but genetic divergence among these was too low for them to be considered species, and morphological differences were not significant. The mtDNA tree identified two clades of eastern Pacific Agathistoma, but many lower-level relationships within Agathistoma were not well resolved, suggesting that more complete taxon sampling and additional genetic data will be needed to establish more robust relationships among Tegulinae.
