First record of the Small-eyed loter Prionobutis microps (Weber, 1907) (Teleostei: Eleotridae: Butinae) in Java, Indonesia

Veryl Hasan, Josie South, Axel Katz & Felipe P. Ottoni
The eleotrid Small-eyed loter Prionobutis microps is found in tropical and subtropical brackish and freshwater environments from Southeast Asia to Australia. This species is currently known to occur in estuaries and the lower to middle reaches of rivers in New Guinea, Northern Australia, Papua (Indonesia), Thailand, Peninsular Malaysia (Malaysia). Records of occurrence on the east coast of India are considered uncertain. Despite this species’ wide distribution there are no published records in Java (Indonesia). We...

First scientific observation of the threatened speartooth shark Glyphis glyphis (Müller & Henle, 1839) (Carcharhiniformes: Carcharhinidae) in Indonesia

Veryl Hasan, Peter Gausmann & Felipe P. Ottoni
The speartooth shark Glyphis glyphis is found in Australia and Papua New Guinea, and it was so far never reported beyond this extension range. The present paper provides the first register of this species outside this known distribution. We collected one of G. glyphis in 2018 at Digul River, Mapi district, Papua province, Indonesia. This record represents the first known occurrence of this species in Indonesia, and an extension of its original geographical distribution in...

Rheocles vatosoa, a new species of freshwater rainbowfish (Atherinomorpha: Bedotiidae) from the Lokoho River basin in Northeastern Madagascar

Melanie L.J. Stiassny, Damaris M. Rodriguez & Paul V. Loiselle
Rheocles vatosoa, sp. nov., an endemic Madagascan rainbowfish, is described from the Lokoho River basin in the region of Andapa in northeastern Madagascar. Rheocles vatosoa has the northernmost distribution of the genus recorded to date. The species differs from congeners in the possession of a single (versus three) interdorsal pterygiophore and is additionally readily distinguished from the other two “northern species”; R. pellegrini, from a locality “one day west of Andapa”, and R. derhami from...

Morphological and electro-physiological evidence for the synonymy of two Marcusenius species (Osteoglossomorpha, Mormyridae) from West Central Africa

Guy G. Teugels, Gert Boden & Carl D. Hopkins
This is a detailed biometric study of 88 Marcusenius specimens (Mormyridae) originating from the Ntem River Basin in southern Cameroon and the Ivindo River in Gabon (West Central Africa) including the type material of M. ntemensis and M. conicephalus. It demonstrates that both nominal species are synonymous. A study of the electric organ and the electric organ discharge of specimens originating from both systems confirmed this. Due to nomenclatorial priority M. ntemensis is considered as...

Two Mediterranean gobiid fishes with an unusual cephalic lateral line canal system

Harald Ahnelt
Gobius ater (Belloti’s goby) and G. paganellus (rock goby) are the only known species of Gobiinae in the northeastern Atlantic, the Mediterranean and the Ponto-Caspian region with continuous oculoscapular canals. These continuous canals are seen as the result of a secondary reconnection of the anterior and posterior oculoscapular canals. Gobius ater and G. paganellus differ from Pacific species of Gobiinae with continuous oculoscapular canals. The latter have a single pore ρ/ρ1 while G. ater and...

A new species of freshwater pipefish (Teleostei: Syngnathidae: Coelonotus) from Papua New Guinea

Vincent Haÿ, Marion I. Mennesson, Philippe Keith & Clara Lord
A new species of Coelonotus, a freshwater pipefish, is described on the basis of six specimens from the Gavuvu River of West New Britain Island (Papua New Guinea). It differs from other Coelonotus species by a combination of morphomeristic values including: number of dorsal fin rays (45-47), number of subdorsal (4-5) and tail rings (35-37). The Folmer DNA barcode fragment of the COI mitochondrial gene shows that this new species is indeed a different genetic...

Description of Upeneus madras (Mullidae), a new goatfish species from SE India (NE Indian Ocean), with establishment of the pori-species group and a review of barbel colour in Upeneus species

Franz Uiblein & James Maclaine
The Madras Goatfish, Upeneus madras n. sp. (Mullidae), is described based on two specimens from Chennai, SE India, that were formerly identified as U. guttatus (Day, 1868), a widely distributed species which has the same type locality. The new species shares white barbels and oblique bars on the lower caudal-fin lobe, seven dorsal-fin spines which decrease proportionally in height and subequal pelvic and pectoral fins with the other eight species of the pori group, a...

First record of the marlin sucker Remora osteochir (Cuvier, 1829) (Carangiformes, Echeneidae) in the Adriatic Sea

Jakov Dulčić, Mišo Pavičić, Iva Žužul, Rino Stanić, Pero Ugarković & Branko Dragičević
Two specimens of marlin sucker Remora osteochir (Cuvier, 1829) were found attached on a Mediterranean spearfish Tetrapturus belone caught in the eastern Adriatic Sea (Croatian coast) with purse seine in December 2020. Species identification was confirmed both morphologically and by genetic barcoding. This finding represents the first record of this species from the Adriatic Sea.

Evidence of trilobed testes in European sardine (Sardina pilchardus)

Marta Caballero-Huertas, Xènia Frigola-Tepe, Jordi Viñas & Marta Muñoz
Abnormal gonads were recorded in male specimens of European sardine, Sardina pilchardus (Walbaum, 1792) captured along the Mediterranean Coast (Northern Spain, Northern Adriatic Sea, and Aegean Sea). Three lobes were identified in the testes of these individuals, what could be considered as gonad segmentation. The prevalence of this abnormality of the testicles’ architecture has reached 2%, 0.99%, and 0.49%, respectively, in the samples of the stocks mentioned above. To knowledge, it is the first documentation...

First record of Squalus clarkae (Elasmobranchii: Squalidae) in the Southwest Gulf of Mexico

Luis Fernando Del Moral-Flores, Sheila Paleo-Delado, Samantha Ballesteros-Hernández & Felipe Galván-Magaña
Squalus clarkae is a Squaliform shark described from specimens collected in the northeastern Gulf of Mexico, but whose distribution, based on genetic studies, would include the northwestern Atlantic. However, its southern distribution in the Gulf remained unknown. Four specimens (two females and two males) with a total length of 54.2 to 61.4 cm were recovered in July 2021 from the catches of the artisanal fishery on the continental slope, south of Veracruz in the southwestern...

A new grenadier (Gadiformes, Macrouridae) from the Mediterranean

Tomio Iwamoto & Nicola Ungaro
Caelorinchus mediterraneus is described from specimens collected in the western and central Mediterranean Sea (Catalan Sea, Ligurian Sea, Adriatic Sea) at depths between 800 and 1200 m. Previous workers had misidentified the species as C. occa, C. labiatus, or C. vaillanti (a synonym of C. labiatus). It differs from those species, in snout shape, squamation, color, and size (maximum length about 30 cm, compared to more than 40 cm), among other characters. The new species...

Apports des isotopes stables (13C/12C, 15N/14N, 18O/16O, 36S/34S 87Sr/86Sr) aux études écologiques sur les poissons

Elise Dufour & Daniel Gerdeaux
Au cours des 20 dernières années, les isotopes stables sont devenus des outils d’investigation courants en écologie. Les applications à l’écologie des poissons sont nombreuses et variées, puisqu’elles concernent la détermination de la place trophique aux échelles communautaires, intra-populationnelles ou inter-populationnelles, la recherche des mécanismes de bioaccumulation des polluants, la détermination de l’origine et la discrimination entre les différents stocks d’une même espèce ou encore le suivi des migrations. Ces applications reposent, d’une part, sur...
