“…The vegetation on the islands has close affinities with the Atlantic Rainforest, though only 5% of the original cover remains (Claudino-Sales 2019). Even so, the islands are rich in endemic species of plants and animals but have a low overall diversity compared to the mainland, which is especially true for terrestrial snails, of which there are three known endemic species (Lopes and Alvarenga 1955). The entire area totals 112.7 km² including land and sea; it was designated as an environmental protection area by the Brazil in 1989 and became a World Heritage Site in 2001.…”

The genus Hyperaulax Pilsbry, 1897 comprises two living species endemic to the oceanic Fernando de Noronha Archipelago, off north-eastern Brazil. They are currently allocated in two subgenera, Hyperaulax s. str. and Bonnanius Jousseaume, 1900, belonging to the family Odontostomidae. Herein we present a taxonomic revision of these species, assessing their familiar allocation within Orthalicoidea, offering updated diagnoses and descriptions, figuring the type materials and further relevant specimens, and providing barcoding DNA sequences. We conclude that Bonnanius is a junior synonym of Hyperaulax, which is classified in Odontostomidae. The genus contains two valid species, H. ridleyi and H. ramagei, both endemic to Fernando de Noronha.

“…It is interesting to note the occurrence of T. n. meretricula on Fernando de Noronha (Lopes and Alvarenga, 1955). When additional material from both Ascension and the latter location is available, an analysis should be made to see whether there is subspeciation taking place similar to that described by Vermeij (1970) Clench (1947) placed P. fasciata in the synonymy of T. rustica rustica Lamarck, the nominate subspecies, which is limited to the western Atlantic.…”

to Zoology, number 189, 41 pages, 24 figures, 3 tables, 1975.-Eighty-nine marine mollusks of Ascension are identified and short synonymies, distributional information, and remarks concerning their morphology, relationships, and zoogeography are given. Comparisons are made between the molluscan faunas of St. Helena and Ascension, overall findings showing that species of both islands are derived in similar proportions from the various other world faunal areas. Species endemicity is many times greater on St. Helena than on Ascension, probably due in part to the considerably greater geological age of the former island.

“…Fernando de Noronha archipelago emerged in the Miocene, 8-12 Myr, due to successive volcanic eruptions during the splitting of the South American and African tectonic plates ( Almeida, 1955 ; Cordani, 1970 ). Mollusc fauna was characterized to be composed mainly of Antillean forms ( Lopes and Alvarenga, 1955 ). Brachidontes exustus was cited in the archipelago by Lopes and Alvarenga (1955 ), Rios and Barcellos (1979 ), and Rios (1994 ).…”

Brachidontes exustus was cited in the archipelago by Lopes and Alvarenga (1955 ), Rios and Barcellos (1979 ), and Rios (1994 ). Nonetheless, the Fernando de Noronha population showed large nucleotide distances from B. exustus from Salvador ( 16S , 16.6%, and COI , 13.9%) and to other Brachidontes species (> 19%), characterizing interspecific levels of differentiation (see Hebert et al 2003 ).…”

“…B. domingensis and B. darwinianus ). B. exustus was recorded for the northeast coast of Brazil ( Klappenbach, 1965 ), for the state of Rio de Janeiro ( Quintanilha, 2017 ), and also for the oceanic islands of Fernando de Noronha ( Lopes and Alvarenga, 1955 ; Rios and Barcellos, 1979 ) and Santa Helena ( Rios, 1994 ). The lack of significant differences among shells from fossil and living specimens also led Aguirre et al (2006 ) to believe that variations in form were only adaptations to different environmental conditions.…”

Molecular and morphometric analysis of nominal Brachidontes exustus (Mollusca, Mytilidae) in Brazilian waters

et al. 2022

Brachidontes exustus (Mollusca, Mytilidae) is mainly distributed in Central America, where it has been recognized as a _lataforma species. This study aimed to determine whether B. exustus extends beyond the Amazon Barrier and southward along the Brazilian West Atlantic coast. Mitochondrial genes coding for cytochrome- c oxidase, subunit I (COI) and 16S subunit of ribosomal _lataforma__ cid (16S rRNA) were analyzed with _lata parameters on Brazilian populations (Salvador, Arraial do Cabo and Fernando de Noronha) of scorched mussels previously recorded as B. exustus . Multivariate morphometric _latafor showed partial discrimination of species. Molecular _latafor confirmed B. exustus at Salvador, a population highly similar to Cartagena (Colombia), both belonging to the Atlantic Clade of the B. exustus complex. This fact adds evidence to the idea of the Amazon outflow as a semipermeable barrier. In the southeast of Brazil, B. exustus was not found; instead, B. darwinianus is the species represented at Arraial do Cabo (state of Rio de Janeiro), associated with brackish _lataf. Scorched mussels from Fernando de Noronha are most closely related to B. puniceus from Cape Verde with 4.4% differentiation. Demonstrating an independent evolutionary history since at least the beginning of the Pleistocene, its proposed new name is B. noronhensis.
