Evanguedes Kalapothakis (2019) Complete mitochondrial genome sequence of Hypostomusfrancisci (Siluriformes: Loricariidae), Mitochondrial DNA Part B, 4:1, 155-157, ABSTRACTHypostomus francisci, commonly known as "cascudo", is a fish of ecological importance found in the upper São Francisco River, Minas Gerais, Brazil. Here we present the complete mitogenome (mtDNA) of H. francisci. The whole molecule is 16,541 bp long and contains 13 protein-coding genes (PCGs), two rRNA genes, 22 tRNA genes, and one control region (D-loop). All the PCGs in the H. francisci mtDNA use the standard ATG start codon, except for Cox1, which utilizes GTG. Seven of the 13 PCGs contain TAA stop codons, three contain a TAG, and three contain the incomplete stop codons TA À or TÀ. ARTICLE HISTORY

“…Possible locality mislabeling or erroneous identifications of lots assigned to the Papari lagoon by Fowler (1941) are realistic possibilities, as already mentioned by Vari (1989) and Ramos et al (2017). These authors noticed that the localities attributed to Psectrogaster saguiru (Lago Papary, Rio Grande do Norte) and Hypostomus eptingi (Fortaleza, Ceará) belong to the basins of the Jaguaribe and Parnaíba rivers, respectively.…”

“…The Mid-Northeastern Caatinga Ecoregion (MNCE), composed by coastal basins fully or partially inserted in the semiarid, was a knowledge gap in the diversity of freshwater fishes until recently (Lévêque et al, 2008;Langeani et al, 2009;Lima et al, 2017). However, in the last decade many ichthyofaunal surveys and taxonomic studies were conducted in the ecoregion (Gurgel-Lourenço et al, 2013;Novaes et al, 2013;Paiva et al, 2014;Silva et al, 2014Silva et al, , 2017Botero et al, 2014;Lira et al, 2015;Ramos et al, 2013Ramos et al, , 2016Ramos et al, , 2017Britzke et al, 2016;Rodrigues-Filho et al, 2016;Teixeira et al, 2017;Zawadzki et al, 2017;Costa et al, 2017;Lima et al, 2017). One of the first fish collections at the MNCE was undertaken by the Stanford Expedition in 1911 when a few drainages in Ceará and Rio Grande do Norte states were sampled (Starks, 1913).…”

Ichthyofauna of Trairí river basin, Rio Grande do Norte state, northeastern Brazil: a century after the study of the naturalist Edwin Starks in the Papari lagoon

Fishes from the coastal basins of the Mid-Northeastern Caatinga ecoregion (MNCE) were first sampled by the Stanford expedition at the beginning of the 20th century, and published by Edwin C. Starks in 1913. This material included specimens from the Papary lake (= Papari lagoon) in the lower portion of the Trairí river basin, draining towards the eastern coast of Rio Grande do Norte State. In 1941, Henry Fowler provided a broad taxonomic study of the freshwater fishes from northeastern Brazil, including material from the Papari lagoon, besides describing four species assigned to this locality. However, these previous surveys focused only in the lower portion of the Trairí river basin and might be incomplete. Given this framework, the present study aimed at perform a wide ichthyofaunal inventory of Trairí river basin and compared with previously surveys performed in the regions. In 2013 and 2014, four expeditions along the whole basin, including the Papari lagoon itself, resulted in 28 species of fishes belonging to 17 families and seven orders. At Papari lagoon area 16 species were registered whereas 26 and 18 species were recorded by Starks and Fowler’s studies, respectively. Considering all records, 50 species were documented in the basin with 14 (28%) new records, including Serrapinnus potiguar, whose distribution was extended to the south. Two species described by Fowler, Pimelodella papariae and Pseudancistrus papariae, were not found in this study or in any fish collection, and are only known from their type-material. These two species can be naturally rare, locally extinct, or there were inaccuracies in their type-locality. However, species of these genera are only found in larger basins of the MNCE, which drains to the north, corroborating the latter assumption. Although not being a definitive list, the recent extensive fish surveys conducted in the MNCE’s coastal basins are helping to elucidate species’ geographic distribution and little knowing taxonomic issues.

“…We also recommend further investigation of Hypostomus carvalhoi (Miranda Ribeiro 1937), Hypostomus nudiventris (Fowler 1941) and Hypostomus salgadae (Fowler 1941), since all these putative dark‐spotted species have their type localities within the MNCE and most were proposed by Fowler (). Recently, Hypostomus eptingi Fowler 1941, another dark‐spotted species from the MNCE described by Fowler (), was formally synonymised with H. jonhii (Ramos et al ., ). A formal taxonomic review, integrating both morphological and molecular data, is also necessary to better define the number of Hypostomus species and their distribution in the MNCE.…”

The mid-north-eastern Caatinga is a semiarid freshwater ecoregion in North-eastern Brazil that is dominated by temporary rivers and is currently classified as one of the least ichthyologically-known ecoregions in the world. The present study aimed to provide an updated checklist of mid-north-eastern Caatinga ecoregion (MNCE) freshwater fish species and evaluate their taxonomic identity using morphology, DNA barcoding and multiple species delimitation approaches. After reviewing published studies and ichthyological collections, 119 species were identified. Among these were 94 putatively valid native and 14 non-native species, five undescribed native species, four new records for the MNCE, 11 potential cases of misidentification and 14 species listed as inquirenda. Additionally, 252 individuals from 49 species were barcoded, revealing three potential taxonomic synonyms. The combined molecular approaches estimated a total of 91 native species, although a finalized species list for the MNCE awaits additional taxonomic revisions and field surveys. This study provides the most up-to-date species checklist for the MNCE and a molecular reference database for identifying MNCE fishes with DNA barcodes. Results highlight the need to integrate traditional taxonomy with molecular approaches to correctly identify species, especially in taxonomically problematic ecoregions such as the MNCE.
