“…A total of 191 specimens of Anchoviella from Brazil, Cuba, French Guiana, Martinique and the United States were analysed. Specimens were tentatively identified based on literature (Whitehead, 1985; Whitehead et al ., 1988; Loeb, 2012, Loeb, 2013; Loeb & Figueiredo, 2014; Barbosa et al ., 2017; Loeb et al ., 2018) and geographic distribution (Figure 1), resulting in the pre‐identification of 131 specimens as A. cayennensis (South America) and 40 as A. perfasciata (Central and North America), including its holotype (MCZ 17965). The type series of A. sanfranciscana , which includes the holotype and 19 paratypes, all collected in the estuary of the São Francisco River, Brazil (Barbosa et al ., 2017), was also examined.…”

“…Anchoviella Fowler 1911 is a New World genus of Engraulinae that includes 15 valid species exclusively found in coastal marine and freshwater environments (Barbosa et al ., 2017; Bloom & Lovejoy, 2012; Loeb, 2012, 2013; Loeb et al ., 2018; Van der Sleen & Bloom, 2018).

“…Possibly cayennensis is merely a southern subspecies [of the former]” (Whitehead et al ., 1988:338). Actually, the origin of the anal fin is also distinctly placed posteriorly in relation to the dorsal‐fin base in some South American freshwater species of the genus, such as Anchoviella carrikeri Fowler, 1941 (Amazon basin) and Anchoviella guianensis (Eigenmann, 1912) (Orinoco and Amazon basins, also coastal between Venezuela and Pará, northern Brazil), but the condition was indeed restricted to A. cayennensis and A. perfasciata among coastal/estuarine species of Anchoviella until the description of Anchoviella sanfranciscana 2017 (Barbosa, Gomes da Silva, da Rocha Araújo & Carvalho, 2017).…”

“…The three species can hardly be differentiated in terms of the external anatomical characters proposed as diagnostic in the literature, except for a slightly smaller number of rakers in the lower portion of the first branchial arch in A. perfasciata (24–30 vs . 28–35 in A. cayennensis and A. sanfranciscana ; Whitehead et al ., 1988; Barbosa et al ., 2017). Other characters proposed by Barbosa et al .…”

“…Other characters proposed by Barbosa et al . (2017) for A. sanfranciscana are rather problematic in terms of description. Likely as a result of this situation, records of A. sanfranciscana are still restricted to the 20 specimens that compose the type series collected in the estuary of the São Francisco River, northeastern Brazil, to which the species was regarded as endemic at the description.…”

Anchoviella cayennensis (Puyo, 1945) is a relatively small-sized, coastal and estuarine western Atlantic species of anchovy distributed from Suriname to southeastern Brazil.The species is morphologically similar to Anchoviella perfasciata (Poey, 1860) from the Central and western North Atlantic, and it has been suggested in the literature that both are actually synonyms. The recently described Anchoviella sanfranciscana (Barbosa et al., 2017) was reported as endemic to the estuary of the São Francisco River, northeastern Brazil. Most characters proposed as diagnostic for A. sanfranciscana in the description are, however, similar to the ones reported for A. cayennensis and A. perfasciata. To determine the complex taxonomic scenario involving the three species, 24 morphometric and 13 meristic characters of 171 specimens tentatively identified as A. perfasciata (including the holotype) and A. cayennensis from the Central and South Atlantic in addition to the holotype and 19 paratypes of A. sanfranciscana (total: 191 specimens) were analysed. The PCAs of morphometric characters indicate the existence of two groups, which are recognized as A. perfasciata and A. cayennensis, with A. sanfranciscana proposed as a junior synonym of the later. Further evidence from gill arch dentition also indicates that A. perfasciata and A. cayennensis are distinct valid species. A redescription of A. cayennensis is presented, with a neotype proposed for the species. Confirmation of the identity of specimens attributed to A. cayennensis indicates that its southern limit of distribution is in the Rio de Janeiro State, southeastern Brazil. An updated taxonomic key for the estuarine and coastal Atlantic species of Anchoviella is also presented.

The increase in the number of Brazilian protected areas has been progressive and, although it is essential for the conservation of biodiversity, it is important to monitor and properly manage these areas, as they present several cases of biological invasions. The Lençóis Maranhenses constitute the peculiar delta of the Americas and are under the consequences of the bioinvasion of tilapias and peacock bass. Collections were carried out in the Lençóis Maranhenses National Park from March/2016 to November/2020, with the aid of gill nets and cast nets. The species were identified with the help of specialized literature and a historical comparison with previous works was carried out. Cytochrome oxidase subunit I was sequenced to confirm identification of non-native species. We recorded the expansion of the occurrence of Oreochromis niloticus, and the first record of the species Oreochromis mossambicus and Cichla monoculus. A total of 31 species belonging to eight orders, eighteen families and twenty-nine genera were identified, indicating a lag in the diversity of species found in relation to previous studies. After 20 years of the first record of invasive fish, there is an expansion of bioinvasion and new cases that indicate a lack of monitoring and containment measures for the species, indicating the fragility of conservation in the area

Characterizing functional morphology and trophic niches in a neotropical Characiforms (Actinopterygii: Teleostei) assemblage in middle Munim River basin, Maranhão, Brazil

Understanding how functionally similar species segregate resources to minimize competition is vital for predicting evolutionary factors and patterns of coexistence. We conducted a study in Mata de Itamacaoca, in the middle Munim River basin, Maranhão, northeastern Brazil, to characterize the functional morphology and trophic niches of five coexisting Characiform species in this area - including a recently described species, and to investigate whether their functional morphology is a key determinant of their trophic niches. Our analysis of functional morphology and diet, employing linear measurements to predict dietary specializations, showed that these species are predominantly generalist insectivores with a significant morphological overlap. This study underscores the influence of species' natural history on their ecological characteristics, contributing to more effective conservation strategies.
