“…Furthermore, and in agreement with the latter, a recent barcoding study with a broader geographical and taxonomical sampling within the Eleotridae, pointed to the Eastern Pacific species G. polylepis as the sister of G. dormitor , and H. latifasciata as sister to the two of them (Guimarães-Costa et al. 2017 ). According to this, G. dormitor and G. polylepis would constitute the geminate species pair in the genus Gobiomorus .…”

We sequenced the complete mitochondrial genomes of three pairs of congeneric peripheral fishes distributed on either side of the Isthmus of Panama in order to test their status as geminate species pairs. Our phylogenetic analysis did not support a sister relationship between Gobiomorus dormitor and G. maculatus and therefore they cannot be considered geminates. The average genetic distance of protein-coding genes between Sicydium altum and S. salvini was more than two times larger than between Atlantic and Pacific Awaous banana, suggesting different timings for their divergence across the Isthmus of Panama.

“…22–30 ). The DNA barcoding approach has permitted considerable advances in the understanding of fish diversity, in particular, the elucidation of taxa with similar traits 31–40 . In the present study, the composition of the fish fauna of the Parnaíba Delta was diagnosed by DNA Barcoding, providing new insights into the local fish diversity in this important coastal complex, while also expanding the global barcoding database.…”

Deltas are dynamic and productive systems of enormous ecological significance, encompassing unique and biologically diverse wetland habitats. Here, we present the first data on the molecular diversity of the fish fauna of the Parnaíba Delta, the largest deltaic formation of the Americas. Partial sequences (626 bp) of the mitochondrial COI gene (Cytochrome c oxidase subunit I) were used to barcode 402 individuals, representing 128 species, belonging to 98 genera, 57 families, 17 orders and two classes. The most abundant orders were the Perciformes, Siluriformes, Gobiiformes, and Pleuronectiformes. The Neighbor-Joining (NJ), Bayesian Inference (BI), and BIN analyses produced 103 molecular clusters, while the Automatic Barcode Gap Discovery (ABGD) and Maximum Likelihood (ML) approaches revealed 102 clusters. The mean conspecific, congeneric and confamilial genetic distances were 0.33%, 14.37%, and 18.60%, respectively. Intraspecific divergence ranged from 0.0% to 1.4%, and all species presented barcode gaps, with the exception of two clusters of Cathorops spixii (OTU 96 and OTU 103), which were separated by a low interspecific distance (1.2%), which overlaps the maximum intraspecific genetic distance (1.4%). The barcode data provide new insights into the fish diversity of the Parnaíba Delta, which will be important for the development of further research on this fauna.

“…Phylogeographic studies of several diadromous fishes in Middle America have also demonstrated population‐level divergence between the Caribbean and Gulf of Mexico ( Dajaus monticola , McMahan et al ., 2013; Dormitator maculatus (Bloch, 1792), Galván‐Quesada et al ., 2016; Gobiomorus dormitor Lacepède, 1800; Guimarães‐Costa et al ., 2017). Awaous banana similarly exhibits this biogeographic pattern, with 1.86% COI divergence between these two clades ( i.e ., Caribbean and Gulf of Mexico).…”

“…Compared to stenohaline or euryhaline fishes, diadromous fishes can exhibit interesting patterns of evolutionary history and population structure given their occupancy of both freshwater and marine systems as integral parts of their life histories. These structured biogeographic patterns have been observed in several diadromous taxa in Middle America, including sleepers (family Eleotridae, Guimarães‐Costa et al ., 2017 and Galván‐Quesada et al ., 2016) and mullets (family Mugilidae, Díaz‐Murillo et al ., 2017 and McMahan et al ., 2013). Intraspecific divergence was recovered across all of these taxa, with different lineages present in Atlantic and Pacific‐slope rivers, as well as multiple lineages within each slope.…”

Diadromous fishes can exhibit interesting evolutionary and population‐level patterns given their use of freshwater and marine environments as part of their life histories. The River goby genus Awaous are prominent members of riverine ichthyofaunas and occur throughout Atlantic and Pacific slopes of the Americas from the southern United States to Ecuador and Brazil. Here we study the widespread and polymorphic Awaous banana complex to assess phylogeographic patterns and test previous hypotheses that all populations of this species in the Americas belong to the same species. Analysis of sequence data based on the mitochondrial cytochrome oxidase I gene shows multiple clades within the Atlantic and Pacific basins, which correspond to previously described species. Additionally, haplotype analysis demonstrates unique and unconnected networks between these species. Within these clades we document biogeographic patterns that are congruent with results of other co‐occurring diadromous species, as well as a novel biogeographic pattern for the region. Our results support the recognition of distinct species of Awaous in the Atlantic (A. banana and A. tajasica) and Pacific (A. transandeanus) basins. These results are concordant with previously established morphological characters permitting the separation of these species.
