“…This result was congruent with the traditional morphometric reconstructed trees [35][36][37][38], based on recent molecular studies [10,17,25] and with a geological vicariant hypothesis involving Cyprinodontiformes [16]. All of them showed Aphaniidae (Aphanius iberus) as a monophyletic family separated from the Cyprinodontidae family (Cyprinodon and Jordanella genera, both included in our phylogenetic tree) [4] with a close proximity to Valenciidae [39]. Currently was published the complete mitogenome of Aphanius farsicus, where A. farsicus was positioned within the same evolutionary clade as the Cyprinodon and Jordanella genera [40].…”

The Spanish toothcarp (Aphanius iberusValenciennes, 1846) is a small fish species endemic to the eastern coastline of the Iberian Peninsula. Along its area of distribution, it mainly inhabits brackish waters which can exhibit large fluctuations in temperature and salinity throughout the year. Aphanius iberus belongs to the family Aphaniidae within the order Cyprinodontiformes and is currently listed as “Endangered” (category IUCN: EN), facing a very high risk of extinction in the wild. The genetics of A. iberus are not well-known since most studies have only evaluated the genetic structure of the species under a conservation framework in order to identify its potential conservation units. In the present study, the entire mitochondrial genome of A. iberus was obtained for the first time in the context of an A. iberus reference genome. The mitogenome was reconstructed and aligned against 83 cyprinodontiformes and two outgroup taxa to create the phylogenetic reconstruction of A. iberus. PartitionFinder was first used to test for the best evolutionary model for both coding and non-coding genes and the phylogenetic analysis was performed using two methods: Maximun-Likelihood approximation (IQ-Tree) and Bayesian inference (MrBayes). Our results show that A. iberus forms a sister group with Orestias ascotanensis, a cyprinodontiform species native to South America. We believe the information gained from this study is valuable for improving our understanding of the historical evolution of A. iberus and that it can be useful for future genomic studies.

“…The mitochondrial genome of the new species has been studied [ 58 ] as well of that of Orestias ascotanensis [ 61 ], the only Orestias included in the study. Both appear in a sister relationship among other cyprinodontiforms, and exhibit 63 base-pairs (bp) of difference (0.38%) across the mitogenome [ 58 ].…”

Morphological and taxonomic descriptions of a new genus and species of killifishes (Teleostei: Cyprinodontiformes) from the high Andes of northern Chile

A new genus and species, Pseudorestias lirimensis, is described from the southern part of the Chilean Altiplano. While sharing several characters that clearly align the new species with Orestias, this new fish is characterized by numerous autapomorphies: the Meckel cartilage is a continuous cartilage that broadly expands posteriorly (in large specimens, it keeps its anterior part and is resorbed posteriorly), the basibranchials are fused into one long element, the second pharyngobranchial is not displaced dorsally over pharyngobranchial tooth plate 3+4, but they are aligned, the anterior and posterior ceratohyals are closely articulated keeping a scarce amount of cartilage between both bones and ventral to them, ossified middle and distal dorsal radials are present in females as well as ossified middle and distal anal radials. Pseudorestias lirimensis presents strong sexual dimorphism associated to size. Females are almost twice as large and long than males, neuromast lines are absent in males, a mesethmoid is present in males, squamation on head is reduced in males, and ossified middle and distal radial of dorsal fin are cartilaginous in males. Pseudorestias and Orestias are suggested as the sole members of the tribe Orestiini. A list of characters diagnosing the tribe is provided. The presence of the new genus is interpreted as a possible result of the ecosystem isolation where the fish is living from surrounding basins—as early as possibly from the Miocene-Pliocene times—and its physical and chemical characteristics. Small populations, living conditions, small habitat, and reduced distribution make this species a strong candidate to be considered critically endangered, a situation already established for all other Chilean species living in the Altiplano. There is high probability it will become extinct due to water demands and climate change in the region.

“…Mitogenomic analyses. We compiled published mitogenomes considered as part of Percichthyidae according to current molecular hypotheses (Lavoué et al, 2014;Betancur-R et al, 2017) Additionally, we sequenced the whole mitogenome of Percilia gillissi from the Maipo River (type locality), a second sample from south of Chile, and Percilia irwini from the Bureo River, Bío-Bío Basin, following Quezada-Romegialli et al (2016a, 2016b. Briefly, total genomic DNA was extracted from dorsal muscle (Aljanabi, Martínez, 1997) and purified with the DNA Clean and Concentrator Kit (ZymoResearch, Irvine, CA, USA).…”

A study including morphological characters and mitogenomics of South American and Australian fishes previously assigned to Percichthyidae was conducted. Results generated from these different data sets reveal major disagreements concerning the content and interpretation of the so-called percichthyids. A phylogenetic analysis based on 54 morphological characters suggests the existence of two major clades: (1) Percichthyidae, including the South American Percichthys and the Australian taxa Macquaria australasica, Macquaria (= Plectroplites), and Maccullochella; (2) Perciliidae with the South American genus Percilia at the base plus more advanced Australian genera Nannoperca, Nannatherina, Bostockia, and Gadopsis. In contrast, molecular and mitogenomic evidence suggests only one clade (Percichthyidae), with the exclusion of species of Macquaria (= Percalates). Additionally, the results reveal the existence of various taxonomic problems, such as the current interpretation of only one species of Percichthys in Argentina, an interpretation that is not supported by the present study; the existence of cryptic species of Percilia as well as of Gadopsis, Nannoperca, and Macquaria that will increase the diversity of the genera; and the need for an extensive revision of species previously assigned to Percalates versus Macquaria. Disagreements point to the need to develop further research on the so-called percichthyids and perciliids.
