    Five species of marine fishes are observed from La Réunion for the first time, and the occurrence of two species is confirmed, observed during a faunal inventory under the OBJECTIF 1000 program. Marine fishes were observed and collected off La Réunion Island (France) with bottom longlines and traps in the upper bathyal zone at 1,000 m depth during a faunal inventory under the OBJECTIF 1000 program. Five species represent first records for the island: Etmopterus granulosus (Günther 1880) (Etmopteridae), Nemichthys scolopaceus Richardson 1848 (Nemichthyidae), Eustomias trewavasae Norman 1930 (Stomiidae), Coelorinchus trunovi Iwamoto & Anderson 1994 (Macrouridae), and Lepidion natalensis Gilchrist 1922 (Moridae). Two species represent confirmed records for the island: Hexanchus griseus (Bonnaterre 1788) (Hexanchidae), Centroscymnus owstonii Garman 1906 (Somniosidae). New depth records are provided for Coelorinchus trunovi Iwamoto & Anderson 1994 and Lepidion natalensis Gilchrist 1922 (1,000 m depth). More thorough sampling efforts would probably result in additional species never before observed in La Réunion.

    Freshwater habitats in Indo-Pacific tropical islands are mainly inhabited by amphidromous fish, which display a marine larval phase while the rest of their life cycle takes place in rivers. Gobiiformes are the most diversified fish component in these ecosystems. In this study, we focused on the status of the widespread Stenogobius genus (Gobioidei). This genus is distributed from the Indian Ocean to French Polynesia. Recently, a first revision of Stenogobius was undertaken leading to the redescription of Stenogobius genivittatus (Valenciennes, 1837) and the placement of 12 species names as synonyms of Stenogobius genivittatus. This paper focuses on the status of nine Stenogobius species supposedly existing in Indonesia, a country well known as one of the freshwater hotspot of biodiversity. The present study is based on 95 specimens, and includes morpho-meristic data and partial mitochondrial COI sequences. Our results show that, at least, four species occur in Indonesia, including the widespread species, Stenogobius genivittatus.

  • Historical records of the Atlantic pomfret, Brama brama (Bonnaterre, 1788) (Teleostei: Bramidae, Braminae), the northernmost records in the Mediterranean Sea and the variability of species adult morphology

    Brama brama, the Atlantic Pomfret or Ray’s Bream, is uncommon in the Mediterranean Sea and very rare in the Adriatic area. We report two historical records of this species from the northern Adriatic Sea, which represent the northernmost records in the Mediterranean. The detailed morphological data of these specimens and their comparison with available data from specimens from the Mediterranean Sea reveal the variability of the morphology of adult specimens.

    Sulawesi is the largest island in the Wallacea biodiversity hotspot. However, data on the ichthyofauna of this island are incomplete, and several known species do not have reference DNA barcodes in public databases; these are necessary, inter alia, to enable non-invasive environmental DNA detection. As a contribution ttowards filling this gap, specimens of two species endemic to South Sulawesi were collected from the Maros karst region in March 2023: Dermogenys orientalis and Lagusia micracanthus. Right pectoral fins were preserved in 96% ethanol for DNA barcoding before preservation of three voucher specimens from each species at Hasanuddin University. DNA extraction and PCR (COI mitochondrial genetic marker) was followed by Sanger sequencing. Data analysis was conducted in MEGA 11. These first barcodes were deposited in GenBank: Dermogenys orientalis accessions OR829330- OR829332 and Lagusia micracanthus accessions OR829336- OR829336. Phylogenetic trees were constructed using homologous sequences obtained through the NCBI GenBank BLASTn routine.

  • New Insights on the Ecology and Biology of the Rare Oxynotus paradoxus from Recent Records

    Oxynotus paradoxus has been recorded in the Eastern Atlantic Ocean, from Senegal to Scotland, at depths from 92 to 1044 m. Despite being present in various Portuguese occurrence checklists, only two scientific studies reported O. paradoxus in Portugal, one off the mainland and the other off the Azores islands. During fishing campaigns onboard a commercial bottom trawler targeting crustaceans, four O. paradoxus specimens were bycaught at the SW of Portugal (SW Iberian Peninsula) at depths varying  between 742 and 1238 m. The latter is a new maximum depth record for this species, which was achieved by an adult female with a total length of 650 mm. Through this adult female, we provide new insights into the ecology and biology of this species.  Morphometric measurements were presented and compared with past studies revealing some intra-specific variability. The low hepato-, gonadosomatic and ecophysiological indices suggest that the adult female was not feeding for some time prior to collection. This study contributes to increase the knowledge of this poorly known species, using an individual approach, which is paramount when targeting rare species.

    Abstract. – We describe a new species of the fossil perciform genus Dapalis (Ambassidae), Dapalis pauciserratus n. sp., based on two articulated skeletons with otoliths in situ from the lower Oligocene of Raljin/Strelac, Babušnica basin, Southern Serbia. This species differs from congeners in the combination of following characters: (i) body elongate, fusiform; (ii) head triangular in shape; (iii) supraoccipital crest distinct; (iv) head without serrations except two large spine-like serrations on the corner of the preopercle; (v) premaxilla with a relatively narrow postmaxillary process located in the distal half; (vi) spines of the first and second dorsal fins, the anal fin and the pelvic fin strong but not massive; (vii) first spine of first dorsal fin long (42% of length of second spine); (viii) otoliths elongate (length : height = 1.4) with a narrow and elongate ostium, indistinct antirostrum, shallow excisura and an asymmetric and prominent rostrum.

  • First records of Lepidorhombus whiffiagonis and Scophthalmus maximus (Scophthalmidae) from the Canary Islands (north-eastern Atlantic)

    The capture of several individuals of Lepidorhombus whiffiagonis and the sighting of two individuals of Scophthalmus maximus represent the first records for these scophthalmid species from the Canary Islands. It is very likely that both species are present in Canarian waters due to natural range expansions from nearby areas. This work also contributes to the knowledge of the morphological and meristic characteristics of the southernmost populations of these eastern Atlantic cold-temperate species.

    The fire-eyed loach Barbucca diabolica, found in Southeast Asian freshwaters, is currently known from Thailand, West Malaysia, Sumatra, and Borneo. Despite this wide distribution, there are no published reports of this species for Belitung Island (Indonesia). We report the first occurrence of B. diabolica for Belitung Island, based on two specimens collected in the East Belitung Province. This new record extends the species distribution about 600 km southeast from Johor (Malay Peninsular, Malaysia), which is about 400 km east from Musi River (Sumatra, Indonesia), and about 500 km southwest from Kapuas River (Borneo, Indonesia). Here we also register the species for an additional island in Sundaland region.
