“…Currently, most of these species live in freshwater and are intolerant of saltwater. According to previous studies, the close phylogenetic relationships among these four genera have been recognized at both the morphological (Hiton 2003;Nelson 2006) and molecular levels (Kumazawa & Nishida 2000;Lavoué et al 2004Lavoué et al , 2011Yue et al 2006;Inoue et al 2009;Mu et al 2012). Furthermore, our results are in good agreement with the commonly accepted phylogenetic consensus, which places A. gigas (Arapaima) and H. niloticus (Heterotis) as a sister-group and the Scleropages species as a sister clade to the two species of Osteoglossum.…”

“…Thus, the study of the divergence among extant bony tongues represents a unique opportunity to elucidate the evolutionary dynamics of these old fishes. The previous studies showed the inter-and intra-species relationships of Osteoglossidae using different genetic markers, such as simple sequence repeats (SSRs) (Yue et al 2004;Mu et al 2011) and mitochondrial DNA (Kumazawa & Mutsumi 2000;Inoue et al 2001;Mohd-Shamsudin et al 2011;Mu et al 2012). To better reconsider the phylogenetic relationships among the family Osteoglossidae and to estimate the divergence time of the genus Osteoglossum, we newly amplified by polymerase chain reaction (PCR) and sequenced the mitochondrial genomes of O. ferreirai Kanazawa, 1966, belonging to the genus Osteoglossum.…”

In this study, we sequenced and assembled the mitochondrial (mt) genome of Osteoglossum ferreirai to re-assess the phylogenetic relationship of the family Osteoglossidae. We determined that the mitogenome of O. ferreirai contains the entire set of 37 mt genes, and the nucleotide composition and gene arrangement were similar to those of other bonytongues. Our phylogenetic analyses exhibited monophyly of the family Osteoglossidae with high bootstrap support, which is in agreement with the currently accepted phylogenetic viewpoint that is based on both morphological and molecular approaches. These findings provide additional informative data for the further study of phylogenetic relationships and help to elucidate a key component of the species radiation process within the family Osteoglossidae.

“…Morphology supports the hypothesis that Pantodon is closely related to Osteoglossidae and Arapaimidae [e.g., Li and Wilson, 1996;Taverne, 1998;Hilton, 2003;Wilson and Murray, 2008], whereas molecular data support an alternative hypothesis in which Pantodon is the sister group of the rest of Osteoglossiformes [Lavoué and Sullivan, 2004;Inoue et al, 2009;Lavoué et al, 2011;Mu et al, 2012;Lavoué, 2016]. The reasons for this 'genetics-morphology' incongruence are still poorly understood, and independent evidence, such as cytogenetic data, is relevant to evaluate which phylogenetic hypothesis should be favored.…”

The monophyletic order Osteoglossiformes represents one of the most ancestral groups of teleosts and has at least 1 representative in all continents of the southern hemisphere, with the exception of Antarctica. However, despite its phylogenetic and biogeographical importance, cytogenetic data in Osteoglossiformes are scarce. Here, karyotype and chromosomal characteristics of the lower Niger River population of the African butterfly fish Pantodon buchholzi, the sole species of the family Pantodontidae (Osteoglossiformes), were examined using conventional and molecular cytogenetic approaches. All specimens examined had 2n = 46 chromosomes, with a karyotype composed of 5 pairs of metacentric, 5 pairs of submetacentric, and 13 pairs of acrocentric chromosomes in both sexes. No morphologically differentiated sex chromosomes were identified. C-bands were located in the centromeric/pericentromeric region of all chromosomes and were associated with the single AgNOR site. FISH with ribosomal DNA probes revealed that both 5S and 18S rDNA were present in only 1 pair of chromosomes each, but did not colocalize. CMA₃⁺ bands were observed near the telomeres in several chromosome pairs and also at the 18S rDNA sites. The mapping of di- and trinucleotide repeat motifs, Rex6 transposable element, and U2 snRNA showed a scattered distribution over most of the chromosomes, but for some microsatellites and the U2 snRNA also a preferential accumulation at telomeric regions. This study presents the first detailed cytogenetic analysis in the African butterfly fish by both conventional and molecular cytogenetic protocols. This is the first of a series of further cytogenetic and cytogenomic studies on osteoglossiforms, aiming to comprehensively examine the chromosomal evolution in this phylogenetically important fish order.

“…mtDNA has been widely used as a genetic marker for genetic structures, species identification, systematic analyses and phylogeography in organisms due to its patterns of maternal inheritance, rapid evolutionary rate and high mutation rate (Avise et al, 1987;Boore, 1999;Mu et al, 2012). Compared to partial mitochondrial sequences, such as Cytb and the D-loop, complete mitochondrial sequences may provide more insight and better resolution from higher-level groups down to closely related species (Velez-Zuazo and Agnarsson, 2011;Powell et al, 2013).…”
