“…curema, M. curvidens, and M. rubrioculus with a PP > 0.95 (Figure 3). The clade including the reference M. liza had a slightly lower support (PP = 0.84), which can be justified by the complex relationship between M. liza and its sibling taxa, M. cephalus, described in previous studies (Durand & Borsa, 2015;Neves et al, 2020). The species delimitation threshold provided by the BOLD platform corroborated the results of our phylogenetic analysis.…”

“…Molecular variation in the COI gene has proven to be a powerful tool to resolve complicated phylogenetic relationships, estimate divergence times, and identify mislabelled specimens in Mugil (Delrieu‐Trottin et al., 2020; Durand, Chen, Shen, Fu, & Borsa, 2012; Durand et al., 2017; Neves et al., 2020). Thus, to identify evolutionary lineages, we performed a Bayesian phylogenetic analysis with posterior probabilities (PP) based on the COI gene.…”

“…However, we did not observe a significant correlation between molecular and morphological divergence ( p = .64), refuting our hypothesis (Figure 4). Notably, two species with high genetic divergence ( M. curema and M. rubrioculus ; 19.5% divergent in COI ), which diverged ~ 23 MYA (Neves et al., 2020), are morphologically very similar according to the MFA and to the ANOSIM results. In contrast, more recently diverged species, such as M. brevirostris and M. rubrioculus , can be easily distinguished morphologically.…”

The biodiversity crisis has had particularly harsh impacts on marine environments. However, there is still considerable uncertainty about how many species have been seriously impacted and the effectiveness of protection measures (e.g., marine protected areas or MPAs) due to high levels of cryptic species in many taxa. Here, we employ an integrative taxonomy approach to mullet species in the genus Mugil. In addition to its high economic value, this genus is notable for having diversified ~29 million years ago without marked morphological and ecological divergence. We obtained 129 specimens of Mugil from the Coral Coast MPA, the largest of its kind in the Tropical Southwestern Atlantic marine province. Although morphometric and meristic traits revealed six taxonomically recognized species, only five mitochondrial lineages were observed. All individuals morphologically identified as M. incilis belonged to the mitochondrial lineage of Mugil curema, which is consistent with misidentification of morphologically similar species and an overestimation of species diversity. Remarkably, Mugil species in our sample that diverged up to ~23 million years ago are also the most morphologically similar (M. curema and M. rubrioculus), suggesting extreme morphological conservatism, possibly driven by similarities in habitat use and life-history traits. This study demonstrates the potential utility of integrative taxonomy (including DNA barcoding) for contributing to the conservation and sustainable use of natural resources.

“…For this reason, several studies have been carried out to solve the phylogenetic relationship and identification of mullet species using different molecular methods [20][21][22][23][24][25][26][27]. Over the past decades, molecular phylogenetic studies have evidenced the presence of many species complexes within the Mugilidae family [2,19,[28][29][30][31][32]. These species complex, often presented as complex of cryptic species due to the absence of evident diagnostic morphometric and meristic characters, are usually sibling species and thus with much more limited distribution range than described for the morpho-species [2].…”

DNA Barcoding of Mullets (Family Mugilidae) from Pakistan Reveals Surprisingly High Number of Unknown Candidate Species

et al. 2021

The mullets are a widespread group of ecologically and economically important fishes of disputed taxonomy due to their uniform external morphology. Barcoding and phylogenetic studies from various locations around the world largely highlighted the species diversity underestimation using morphological criteria used to establish the taxonomy of the family. Here, we investigated the mullet species diversity from Pakistan, a biogeographic area where nearly no mullet species were genetically characterized. Morphological examination of 40 mullets reveals 6 known species (Planiliza macrolepis, P. klunzingeri, P. subviridis, Crenimugil seheli, Ellochelon vaigiensis, and Mugil cephalus). Using a references DNA barcode library, the DNA barcode-based species identification flagged eight molecular operational taxonomic units (MOTUs) belonging to five genera (Crenimugil, Ellochelon, Mugil, Osteomugil, and Planiliza). Among these MOTUs, only one was already present in Barcode of Life Data system, all other representing new Barcode Index Numbers (BIN). These results emphasize the importance of the recognition of cryptic species and the necessity to re-evaluate the overall diversity by the genetic characterization of different species of this family. DNA barcoding is an effective tool to reveal cryptic species that need to be considered in conservation and management measures of fisheries in Pakistan.

“…In addition, mugilids include a complex of estuarine species morpho‐ecologically similar but with a long and differentiated evolutionary history. Mugil curema and M. rubrioculos are among the species that have diverged in more time; nonetheless, they are morphologically more similar than M. liza , which is the most recent species (Neves et al ., 2020).…”
