Abstract.
Studies of ichthyofauna in Argentina have gained greater relevance in recent years and are constantly being updated. The yellow catfish (

Pimelodus maculatus

) has a wide distribution in the country and neighboring countries, but it was not part of the fish fauna of the province of Córdoba. The objective is to report for the first time its presence in the provincial territory. Fish were captured in the Tercero river (32º41’09’’S 62º29’14’’W) and in La Helvecia shallow lake (33º25’35’’S 62º53’25’’W), located in Del Saladillo wetlands. Meristic and morphometric characters and somatic relationships of nine specimens are presented. In addition, water characteristics of the lentic environment are provided. From this work is broaden the western distribution of P. maculatus in central region of Argentina.

Key words. Ichthyofauna, Córdoba, Siluriformes, yellow catfish, Pimelodus.

Abstract. We report the occurrence of

Bunocephalus larai

in the Ivaí river basin, and expand the geographic
distribution of this species to southern latitudes of the Upper Paraná river basin. Four individuals
were captured through electrofishing in the Muquilão River, a tributary of the Ivaí River, Paraná, Brazil.
The sampled site was within a conservation unit in the municipality of Iretama. The captures occurred in a
marginal backwater of a 20–40 m wide stretch and 0.3–0.7m deep, characterized by sand/clay and leaf
litter as predominat bottom substrate. Our study demonstrates the importance of ichthyofaunistic studies in
headwaters of rivers.

Key words. Aspredininae, center-west Paraná, conservation, ichthyofauna inventory, Paraná River

Abstract
Striped eel

Plotosus lineatus

(Thunberg, 1787) was observed during scuba diving at a depth of 13 m at the Pirates' Cave dive site off the coast of Alanya in the Antalya Bay on the Mediterranean coast of Türkiye on 23 September 2024. In this study, Plotosus lineatus, which entered the marine waters of Türkiye for the first time in 2016 from Iskenderun Bay, was observed to continue its westward progress from the coasts of the Mediterranean Sea.

From the introduction of this paper, P. lineatus was first caught in the Mediterranean in 2001, along the Southern Israel coastline. The species is now found in the Northern Mediterranean, along the central Türkiye coastline.

Abstract.

Glyptothorax robustus

Boeseman 1966 is a vulnerable catfish species that is known to be distributed across Java and Sumatra. The objective of this research is to document, for the first time, the presence of G. robustus in Bangka, Indonesia, and to update the species' geographic distribution. This discovery of a freshwater fish in a new location significantly contributes to the understanding of its biogeography. A purpose-sampling approach was employed to collect the specimens. The species were identified morphologically and molecularly through DNA barcoding. On 20 January 2023, five G. robustus specimens were collected from the Bumang River in Bangka Island using fish traps. The occurrence of G. robustus at this location represents the most northerly record of this species and extends its known geographic range. Additionally, this new site is approximately 200 km north of the nearest known location on Sumatra Island and 300 km north of the nearest known location in Java. This record expands the documented distribution range of G. robustus and enhances our understanding of this species. Furthermore, an updated record of the G. robustus DNA sequence from the cytochrome c oxidase subunit I (COI) gene is presented. This sequence constitutes the first DNA barcode for Indonesia and has the potential to support future studies in biogeographical and ichthyological research. The DNA sequence was registered in NCBI GenBank under the accession code OR144414. This DNA barcode can serve as a standard for identifying G. robustus and will support future DNA and biotechnology-based studies.

That's not G. robustus, though.

Intersecting. What are your thoughts on the ID of this fish? And what did you think of the rest of the paper? (I presume you have access to it)

Cheers, Eric

[Silurus]

This is the species commonly found throughout the Malay Peninsula and southern Thailand, identified as either G. fuscus or G. callopterus (depending on who you choose to follow). I am not a big fan of using mitochondrial sequences to identify Glyptothorax.

Hypostomus khimaera

Tencatt, Zawadzki & Froehlich was originally described from the state of Mato Grosso do Sul, Brazil (15°39’03"S 57°12’54"W) and is known as a semipopular species in the international ornamental fish trade. The type locality of H. khimaera is located around 400 km in the north-east of the herein described new location. This is the first record from Bolivia and increases the species’ extension range drastically to the west.

Key words: ornamental fish, Paraguay River basin.
