“…As a matter of fact, the conservative external morphology of the family is at the basis of many systematic problems, as evidenced by the reduction of 233 nominal species to only 80 valid species (Pauly & Froese, 2010). Specifically considering mullet in the area, through different mtDNA markers (Fraga et al, 2007;Heras et al, 2009;BOLD), at least three different clusters can be identified within M. curema, which also include other mullet species. Similarly, in the same species complex, from a cytogenetic point of view, in addition to the two cytotypes described above, it has to be mentioned the chromosome complement of M. rubrioculus, formerly considered M. curema ( Nirchio et al, 2003Nirchio et al, , 2007, which has allowed to confirm it as a valid species.…”

Karyotype characterization of Mugil incilis Hancock, 1830 (Mugiliformes: Mugilidae), including a description of an unusual co-localization of major and minor ribosomal genes in the family

This study reports the description of the karyotype of Mugil incilis from Venezuela. The chromosome complement is composed of 48 acrocentric chromosomes, which uniformly decrease in size. Therefore, the homologues can not be clearly identified, with the exception of one of the largest chromosome pairs, classified as number 1, whose homologues may show a subcentromeric secondary constriction, and of chromosome pair number 24, which is considerably smaller than the others. C-banding showed heterochromatic blocks at the centromeric/pericentromeric regions of all chromosomes, which were more conspicuous on chromosomes 1, given the C-positive signals include the secondary constrictions. AgNO 3 and fluorescent in situ hybridization (FISH) with 45S rDNA demonstrated that the nucleolus organizer regions are indeed located on the secondary constrictions of chromosome pair number 1. FISH with 5S rDNA revealed that the minor ribosomal genes are located on this same chromosome pair, near the NORs, though signals are closer to the centromeres and of smaller size, compared to those of the major ribosomal gene clusters. This is the first description of co-localization of major and minor ribosomal genes in the family. Data are discussed from a cytotaxonomic and phylogenetic perspective.Se presenta la primera descripción del cariotipo de Mugil incilis de Venezuela. El complemento cromosómico está compuesto por 48 cromosomas acrocéntricos uniformemente decrecientes en tamaño. Por lo tanto, los homólogos no pueden ser claramente identificados, con excepción de uno de los pares de mayor tamaño, clasificado como número 1, cuyos homólogos poseen una constricción secundaria subcentromérica, y el par de cromosomas número 24, considerablemente más pequeño que los otros. El bandeo-C reveló bloques heterocromáticos en las regiones centroméricas/pericentroméricas de todos los cromosomas, más conspicuas en el cromosoma 1 en el que las señales C-positivas se encuentra localizada precisamente en la constricción secundaria. La tinción con AgNO 3 y la Hibridación Fluorescente in situ (FISH) con sonda 45S rDNA revelaron que las regiones organizadoras del nucléolo están ciertamente localizadas sobre la constricción secundaria del cromosoma número 1. FISH con 5S rDNA reveló que los genes ribosomales menores están ubicados en este mismo par cromosómico, en posición proximal a las NORs, aunque cercanas al centrómero y de menor tamaño en comparación con los clúster de genes ribosomales mayores. Ésta es la primera descripción de co-localización de genes ribosomales mayores y menores en la familia Mugilidae. Los datos se discuten bajo perspectivas citotaxonómicas y filogenéticas.

“…More specifically, Durand et al (2012) showed that a proportion of the species with large distribution ranges, such as Mugil cephalus Linnaeus, 1758 and M. curema Valenciennes, 1836 consists of cryptic species. Specifically referring to M. curema , different mtDNA lineages had been previously identified along the American Atlantic coasts by Heras et al (2006, 2009) and Fraga et al (2007). Unfortunately these studies did not adopt a uniform nomenclature for the lineages (see Rossi et al 2016 for a detailed review) and did not cover the entire species range, that includes both the Eastern and Western Atlantic coasts and the Eastern Pacific coast (Froese and Pauly 2016).…”

Recent molecular phylogenetic analyses have shown that the Mugil curema Valenciennes, 1836 species complex includes M. incilis Hancock, 1830, M. thoburni (Jordan & Starks, 1896) and at least four “M. curema” mitochondrial lineages, considered as cryptic species. The cytogenetic data on some representatives of the species complex have shown a high cytogenetic diversity. This research reports the results of cytogenetic and molecular analyses of white mullet collected in Ecuador. The analyzed specimens were molecularly assigned to the Mugil sp. O, the putative cryptic species present in the Pacific Ocean and showed a 2n = 46 karyotype, which is composed of 2 metacentric and 44 subtelocentric/acrocentric chromosomes. This karyotype is different from the one described for M. incilis (2n = 48) and from those of the two western Atlantic lineages Mugil curema (2n = 28), and Mugil margaritae (2n = 24). Data suggest the need for a morphological analysis to assign a species name to this Pacific lineage.

“…The lower number of lateral series scales in M. liza and parapatry in its northernmost geographic range allowed its separation from M. platanus (Menezes 1983;Cousseau et al 2005;González Castro et al 2008). Nevertheless, the unexpected similarity detected between M. liza and M. platanus on molecular bases (Fraga et al 2007;Heras et al 2009) led Heras (2010) and Menezes et al (2010) to merge M. liza and M. platanus into a single species, M. liza, according to the principle of priority of the International Code of Zoological Nomenclature. In turn, it is worth noting that the re-described M. liza (Menezes et al 2010) (including both M. liza and M. platanus), was identified as one of the lineages that constitute Mugil cephalus species complex (Heras et al 2009;Durand et al 2012;Whitfield et al 2012;Siccha-Ramirez et al 2014;Jamandre et al 2014).…”

With this work we addressed some molecular systematic issues within the Mugil cephalus species complex. Particular attention was paid to the debated situations of: (i) Mugil liza, occurring in partial sympatry with Mugil cephalus in the northwestern Atlantic, and (ii) Mugil platanus, considered by some authors a synonymy of the former species and distributed in the southwestern Atlantic. We sequenced 79 individuals of a 465-bp portion of the mitochondrial control region (CR) from 8 western Atlantic and 2 Mediterranean localities. In addition, all CR sequences available from GenBank for the studied taxa were added to our dataset, for a total of 323 individuals. Overall, 229 haplotypes corresponding to 8 divergent monophyletic lineages were detected. Results of phylogenetic analyses were consistent with the occurrence of past speciation events producing the observed lineages. Of these lineages, 7 correspond to cryptic species and one is constituted by M. liza and M. platanus. As a matter of fact, these 2 taxa constitute a single lineage within the M. cephalus species complex. However, individuals of M. liza/M. platanus lineage analyzed by means of the 18 mitochondrial markers available in GenBank exhibited a degree of genetic diversity consistent with highly divergent populations. Of the 8 lineages detected, the Mediterraean one (type locality) corresponds to M. cephalus; the lineage M. liza/M. platanus should be named M. liza, under the priority principle, and the left 6 lineages need formal description.
