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.

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.

ABSTRACT

Olyra praestigiosa

, an anguilliform catfish was first described exclusively from Darjeeling Himalayas of north Bengal. However, during an ichthyological survey along Tissa river system from February 2023 to April 2024, 8 individuals of Olyrids were collected from 7 distinct sampling locations which were later identified as O. praestigiosa. Additionally revealing it’s occurrence very distant from the original type locality of Chel river in West Bengal. Consequently signifying the first report of O.praestigiosa from the state of Arunachal Pradesh. It is defined by having an anguilliform body, first and second dorsal fin rays being non-ossified as well as the upper caudal fin lobe being significantly expanded. A comparison of morphological characteristics of Olyra praestigiosa specimens collected from the Tissa River system with the original description of O. praestigiosa available in the literature revealed slight variation in dorsal fin to adipose fin distance as well as wider range of adipose fin base length in proportion to it’s standard length. Additionally the altitudinal range of its distribution was expanded from 382 m in type locality to 212 – 919 m in Tissa river originating in the Indo-Myanmar borders.

Jawad, L, AM Al-dirawi, SS Güçlü & OF Al-sheikhly, 2025. The first report of non-indigenous catfish, Bagarius bagarius (Family: Sisoridae) in the inland waters of northeastern Iraq. Acta Aquatica Turcica 21: 179–187.

Abstract

A single specimen of Bagarius bagarius (Hamilton, 1822), a freshwater catfish native to the Indian subcontinent, has been documented for the first time in the inland waters of Iraq. The individual was caught by angling from the Sirwan River (Diyala Province, northeastern Iraq; 34°20'46.22"N, 45°10'23.82"E) on 3 July 2024 and, and measured 370 mm in total length. This discovery represents the first confirmation of this non-native species in Iraqi freshwater ecosystems and highlights the increasing role of the global aquarium trade in facilitating aquatic species invasions. The unintended introduction of B. bagarius into this ecosystem is likely attributable to ornamental fish trade, which has been implicated in translocation of more than 1,000 freshwater species in more than 125 countries. Such trade practices pose significant challenges for natural resource managers to identify and mitigate potential invasive species due to the extreme diversity of taxa traded.

This is not Bagarius, but an extremely large Glyptothorax, likely G. cous.
