“…However, several nodes in this phylogeny were poorly supported, leaving relationships open to future change. A more recent study based on one nuclear and four mitochondrial markers, included all species of Holacanthus and two outgroups (Pygoplites diacanthus and Pomacanthus zonipectus) (Alva-Campbell et al, 2010). This latter phylogeny was very similar to the phylogeny presented here based on RADseq markers (Fig.…”

“…Sampling and locality of individuals were described previously (Alva-Campbell et al, 2010). Briefly, H. africanus, H. tricolor, H. bermudensis, H. ciliaris, H. limbaughi, and H. passer, were collected in Cape Verde Islands, Panama and Brazil, Florida, Florida and Brazil, Clipperton, and Mexico, respectively.…”

“…Genetic divergence between geminate species varies, and this variation is in part due to variability in substitution rates and in part due to ecological and evolutionary characteristics of specific taxa that determine the actual time of separation between geminates (Knowlton and Weigt, 1998;Lessios, 2008). In general, however, there is remarkable consistency in divergence (time and rate) among geminate taxa, as is the case for the angelfish genus Holacanthus (Alva-Campbell et al, 2010;Lessios, 2008).…”

“…In some cases, such as for Holacanthus angelfishes, sister clades (rather than sister species) were found to be geminates (Alva-Campbell et al, 2010). Indeed, a phylogeny of the entire Holacanthus genus (seven species), based on one nuclear and four mitochondrial molecular markers showed that the geminate sister clades included H. bermudensis and H. ciliaris in the Tropical Western Atlantic (TWA), and H. passer, H. clarionensis, and H. limbaughi in the Tropical Eastern Pacific (TPE) (AlvaCampbell et al, 2010 et al, 2004).…”

“…In contrast, the Clipperton angelfish, H. limbaughi, is restricted to Clipperton Atoll, and the Clarion Angelfish, H. clarionensis, is mainly found at the Revillagigedos Archipelago (with a few vagrants found at the southern tip of Baja California and Clipperton Atoll), (Allen and Robertson, 1994), lending to the idea that peripatric speciation may have been involved in this group (Alva-Campbell et al, 2010) (Fig. 1).…”

a b s t r a c tIn this study we estimated the timing of speciation events in a group of angelfishes using 1186 RADseq markers corresponding to 94,880 base pairs. The genus Holacanthus comprises seven species, including two clades of Panama trans-Isthmian geminates, which diverged approximately 3-3.5 Mya. These clades diversified within the Tropical Eastern Pacific (TEP, three species) and Tropical Western Atlantic (TWA, two species) which our data suggest to have occurred within the past 1.5 My in both ocean basins, but may have proceeded via different mechanisms. In the TEP, speciation is likely to have followed a peripatric pathway, while in the TWA, sister species are currently partially sympatric, thus raising the possibility of sympatric speciation. This study highlights the use of RADseq markers for estimating both divergence times and modes of speciation at a 1-3 My timescale.

A wide variety of species are distinguished by slight color variations. However, molecular analyses have repeatedly demonstrated that coloration does not always correspond to distinct evolutionary histories between closely related groups, suggesting that this trait is labile and can be misleading for species identification. In the present study, we analyze the evolutionary history of sister species of Prionurus surgeonfishes in the Tropical Eastern Pacific (TEP), which are distinguished by the presence or absence of dark spots on their body. We examined the species limits in this system using comparative specimen‐based approaches, a mitochondrial gene (COI), more than 800 nuclear loci (Ultraconserved Elements), and abiotic niche comparisons. The results indicate there is a complete overlap of meristic counts and morphometric measurements between the two species. Further, we detected multiple individuals with intermediate spotting patterns suggesting that coloration is not diagnostic. Mitochondrial data recovered a single main haplotype shared between the species and all locations resulting in a complete lack of structure (Φ ST = 0). Genomic analyses also suggest low levels of genetic differentiation ( F ST = 0.013), and no alternatively fixed SNPs were detected between the two phenotypes. Furthermore, niche comparisons could not reject niche equivalency or similarity between the species. These results suggest that these two phenotypes are conspecific and widely distributed in the TEP. Here, we recognize Prionurus punctatus Gill 1862 as a junior subjective synonym of P. laticlavius (Valenciennes 1846). The underlying causes of phenotypic variation in this species are unknown. However, this system gives insight into general evolutionary dynamics within the TEP.
