A confirmed record of the European catfish Silurus glanis L., 1758 (Actinopterygii: Siluriformes: Siluridae) from the southern marshes of Iraq, with a new anatomical set of characters to separate S. glanis and S. triostegus. Integrative Systematics: Stuttgart Contributions to Natural History, 3(1), 85-100.

Abstract
Investigations conducted in the southern Iraq freshwater systems allowed the authors to collect the European catfish,

Silurus glanis

L., 1758. These are the first confirmed records of S. glanis from the freshwater systems in Lower Mesopotamia, based on 13 adult specimens, each 325–525 mm in total length. Furthermore, a new set of anatomical characters of S. glanis and S. triostegus from Chibayish marsh area, south of Iraq, was examined to reveal similarities and differences between the two Silurus species. In addition to the traditional separation of the two species of Silurus by number of barbels, these two species can now be recognised based on a new set of morphological and osteological features.

Hypostomus uruguayensis

(Siluriformes: Loricariidae) in Argentina and first record for Bolivia. Molecular, morphology and biogeography data. Zootaxa, 4996(1): 2 July 2021.

In recent years, the evolutionary history of the catfish genus Hypostomus has attracted much interest (Cardoso et al. 2021; Jardim de Queiroz et al. 2020; Silva et al. 2016). However, the identification of species of this genus is challenging, given the complex taxonomy of the group and the scarce morphological information available for many taxa. Accurate taxonomic identification is essential to estimate the biodiversity in freshwater environments and the discover of new fish species contributes not only to assess the diversity of regional fauna but also to reconstruct the geomorphological evolution of the river basins, notably in South America. The application of multi-source approaches takes advantage of the complementarity between disciplines to estimate the species diversity, especially among those with an obscure taxonomic status (Dayrat 2005).
Hypostomus constitutes an assemblage of more than 150 species of bottom-dwelling fishes with algivorous or detritivore diets that are widely distributed throughout South America (Fricke et al. 2021). Within the La Plata Basin (which includes the Paraguay, Paraná, Uruguay and Rio de La Plata rivers) the diversity of species of this genus is being revised (Cardoso et al. 2011, 2012, 2016, 2019). However, there are still many studies to be done given problems within the genus, the excessively short original descriptions of many species and the mistaken species identifications, including in scientific collections.

Hypostomus uruguayensis

(Reis et al. 1990) was originally described from the Uruguay River Basin in Brazil and Uruguay, Reis et al. (1990) distinguishing it from other Hypostomus from the Uruguay River by a very light ground color with darker dots, lower number of lateral plates (26-27) and a strongly concave caudal fin margin. This species was then cited for Argentina (Boltovsky & Cataldo 1999) and its distribution was expanded into the Lower Paraná River (Almiron et al. 2015; Casciotta et al. 2016).
The specimens examined in this work were collected in the Bermejo River in Argentina and in the Pilcomayo River in Bolivia (Figures 1 and 2). Most of the sequences used here are available in GenBank, but two new sequences were added (accession numbers in Figure 1). Tissue sampling, DNA extraction, PCR amplification of D-loop mitochondrial marker and sequencing were following (Cardoso et al. 2011). With a total of 35 sequences, we found the best substitution model and inferred the phylogeny of the genus using the Maximum Likelihood method in Mega v7 (Kumar et al. 2016). Noe support was assessed using 1000 bootstrap replicates. The fish specimens from Argentina were fixed in formalin and then in ethanol 70% and are deposited at the Foundation Felix de Azara (Institution Code: CFA-IC). Morphometrics follow Reis et al. (1990).

Hortle, KG & S Phommanivong, 2021. The first record from Laos of Plotosus canius. Ichthyological Exploration of Freshwaters doi:10.23788/IEF-1167.

Abstract

We record the first capture from Laos of the diadromous eel-tail catfish Plotosus canius as a single specimen of total length 1111 mm from Phapheng Channel, which is the most easterly anabranch of the Mekong in the Khone Falls system in southern Laos. The capture location is about 2.5 km downstream of Phapheng Waterfall and about 2.1 km upstream of the Cambodian border with Laos. As the location is about 720 km from the sea and at least 500 km upstream of any possible saline influence, this record shows that some large individuals of this diadromous species, which breeds in brackish waters, may penetrate long distances into freshwaters, where they feed on crabs and molluscs.

Potamoglanis wapixana

(Siluriformes: Trichomycteridae) into the Essequibo River basin, Guyana. Journal of Fish Biology.

https://onlinelibrary.wiley.com/doi/abs ... /jfb.14841

Abstract
Morphological examination of Potamoglanis specimens from three localities in the Essequibo River basin, Guyana, and one location in the Branco River basin, Brazil, confirmed their identification as P. wapixana – a species originally described from only the Branco River basin. Morphological similarity of these miniature catfishes on opposite sides of the Rupununi savannah watershed divide and new records from lentic habitat suggest that either their modern populations predate the Pliocene division of the Branco and Essequibo rivers or that the species is capable of living in and/or migrating across the Rupununi Portal – a seasonally flooded hydrological connection known to facilitate movement of mostly much larger fishes between the Branco and Essequibo basins.

Thanks to a tip from @shovelnose, he pointed out that the fish shown in the photos from this paper is not

Arius

. It's a form of

Sperata

, which is also found in the same area. After studying the distribution of Sperata in this area using GBIF, and reading a paper (Gupta, S. (2015). Review on Sperata seenghala (Sykes, 1839), a freshwater catfish of Indian subcontinent. Journal of Aquaculture Research & Development, 6(1): 1-6.), I believe the fish in these photos is

Sperata seenghala

, and not

Sperata aor

which is also found in the area. I based my conclusion on shorter barbels not reaching tips of pelvic fins, and a more posterior placement of adipose fin). Here's my work (photo). I may be wrong. Any opinions?

Ugh. Another change-up. @shovelnose was able to send me a more recent and more reliable review of Sperata, and apparently the fish in these two photos is not S. seenghala, but are most likely

Sperata aor

. I will move the photos accordingly.

Abstract
Specimens of

Imparfinis

were recently collected in northwestern Argentina from the Bermejo River basin (Salta and Jujuy Provinces), del Valle River (Salta Province) and Horcones River (Santiago del Estero Province). An integrative approach to taxonomy, combining a detailed morphological study and molecular phylogenetic analyses, was applied in order to determine the species identity of these specimens. A principal components analysis of morphological data clustered the specimens from northwestern Argentina and from the Amazon basin, indicating a close morphological resemblance. Also, a molecular phylogenetic analysis showed populations of I. guttatus from Argentina and Peru forming a clade. According to the conducted haplotype network analysis these populations are distinct in two mutations. Thus, in absence of morphological or molecular data indicating the contrary, the combined method supports the identity of the specimens from the tributaries of the Paraguay River in Argentina as

Imparfinis guttatus

, whose type locality is in the upper Beni River basin in Bolivia. This contribution is also the first record for this species from Argentina. The disjunct distribution of I. guttatus provides new evidence reinforcing the hypothesis for the origin of the Paraguayan ichthyofauna. We also provide an approach to the phylogenetic relationships of Imparfinis in Heptapteridae.

Abstract
Few studies have addressed the composition of fish assemblages of the freshwater Río de la Plata (RdlP) and have only been limited to species lists gathered over the last two centuries. As such inventories have never been reviewed or validated by fish sampling, the richness and structure of RdlP fish assemblage are poorly known. Hence, we conducted an exhaustive literature review and a fieldwork in six coastal points of Argentina to update the species composition and determine the hierarchical structure of the fish assemblage. From the 206 species registered in the literature, 48 were not confirmed, 13 were absent, five were taken as synonymized species, 29 were supported by literature and 107 were confirmed; one was an established exotic species, and three were a non-established exotic species. The findings reported here suggest that the fish assemblage currently comprises 141 species, including four new records. Analysis of fieldwork data in number and weight of fish captured resulted in an assemblage hierarchical structure of five dominant, 22 frequent, and 45 rare species; 16 dominant, 11 frequent, and 45 rare taxa, respectively. These results could be used as baseline to monitor, manage, and preserve neotropical fish species in their southern distribution boundary.

Note: I have to wonder how this paper applies to previous reports: Specifically, the 2018 paper by Souza-Shibatta et al. that reappraised M. cottoides, and in that paper they suggested there is an undescribed type of Microglanis more southerly than

Microglanis malabarbai

, with the North-South geographic dividing line being around the Rio Cuareim. Is this report confirming actual M. malabarbai? Or is it discovering a more southerly distribution of this undescribed Microglanis?

Abstract
In 2016,

Amblyceps waikhomi

from the Brahmaputra drainage of Arunachal Pradesh, India, was described. Based on morphometric and meristic characteristics, we report the first-ever sighting of A. waikhomi from the Singhiya River in Morang district. A deeper body depth at the anus sets the A. waikhomi apart from its congeners. The river systems of Nepal are home to two Amblycipitidae species, including this one.

Amblyceps waikhomi

A. waikhomi (top) vs A. mangois (bottom)

Point of concern: The paper states the fish were found in the "Singhiya River in Morang district" and lists the coordinates of the Singhiya River as 26.913° N, 87.1570° E. But when mapped, these coordinates align with the Koshi River on the border between the Udayapur and Dhankuta Districts, where the Koshi splits into the Sunkoshi, Arun and Tamor Rivers. By contrast, Google Maps places the Singhiya river around 26.537° N, 87.306° E.



I'm not sure what to make of that difference, but it makes me wonder where exactly the fish was found.

The lack of detailed knowledge about the diversity, distribution and biology of the fish in the province, together with the permanent introduction of exotic species such as salmonids, added to the anthropic activity associated to wetlands, threaten the conservation of the fish species richness. To date, for San Juan there is only a single report of P. laticeps collected in the Zonda department in Presidente Sarmiento Protected Natural Area. Specimens of P. laticeps are reported for the departments of Jachal, Ullum, Rivadavia, Zonda and Calingasta, expanding its distribution to its westernmost extreme towards the central Andes of Argentina.

Abstract

Rhyacoglanis pulcher is a rare Neotropical rheophilic bumblebee catfish known only from the type locality in the Cis-Andean Amazon region, Ecuador, and the type-species of the genus. So far, the three syntypes collected in 1880 were the only specimens unambiguously associated to the name R. pulcher available in scientific collections. Recently, a specimen was discovered in a fast-flowing stretch of the Villano river, a tributary of the Curaray river, Napo river basin, Ecuador, representing a new record after nearly 140 years. Here, we present this new record, identified by morphology, provide the DNA barcode sequence of the specimen, and propose why the species of Rhyacoglanis are scarce in zoological collections. Additionally, we discuss the intraspecific variation in the color pattern observed in R. pulcher.

Thanks HH!

Now I'm wondering where we got the occurrence data for

Rhyacoglanis pulcher

in the Madre de Dios. I don't see that referenced in any Taxonomy/ Science News post here. I'm wondering if that data (wherever it came from, IDK) should be

Rhyacoglanis epiblepsis

or Rhyacoglanis cf. or aff. pulcher.

Also, this paper points out the existence of a specimen, possibly a new species, on the Rio Das Mortes. I've created an entry called

Rhyacoglanis sp`Rio Das Mortes`

.

Abstract

Aspidoras fuscoguttatus

Nijssen & Isbrücker, 1976 is a small, relatively common armored catfish considered endemic to the upper Paraná river basin. Here, based on recent collections, as well as morphological and molecular evidence, the known geographic distribution of this species is extended to the basin of the São Francisco River. Specimens were collected during biological surveys in two unnamed tributaries of the Paraopeba River, in the headwaters of the São Francisco River. The new records may be a consequence of headwater stream-captures between São Francisco and upper Paraná drainages. Continued surveys are needed to assess and mitigate natural and human impacts, including biological exchanges between basins.

Abstract

Hypostomus khimaera

Tencatt, Zawadzki & Fröehlich, 2014 is a species native to the rio Paraguay basin, but it is recorded here from the upper rio Paraná basin for the first time. Our new record was made in the córrego Mimoso, a tributary of the rio Anhanduí, approximately 180 km from the closest previously reported locality. We are unsure whether the occurrence of this species in the upper rio Paraná basin is a consequence of natural phenomena, such as headwater connection during floods or stream capture, or an artificial introduction. Together with the invasive H. cochliodon Kner, 1854, H. khimaera is the second species of the H. cochliodon group recorded in the upper rio Paraná basin. Here, we provide an updated diagnosis of H. khimaera and highlight the differences in opercle exposition as the easiest way to differentiate it from the syntopic and morphologically similar H. cochliodon.

ABSTRACT
The marine catfish

Genidens barbus

(Siluriformes, Ariidae) is a large species of commercial importance in the south of Brazil and the Parano-platense region. It is distributed from Rio de Janeiro, Brazil, to the Río Negro estuary and even in the Chubut River estuary, Chubut, Argentina. It has occasionally been reported in southern Patagonia. This work reports the presence of this species in the Puerto San Julián bay, Santa Cruz, Argentina. Taxonomic identification was supported using morphological characters. The presence of this species in southern territories raises unknowns and motivates us to carry out new studies on their dynamics and migratory habits.

RESUMEN
El bagre marino

Genidens barbus

(Siluriformes, Ariidae) es una especie de gran importancia comercial en el sur de Brasil y la región Parano-platense. Se distribuye desde Río de Janeiro, Brasil, hasta el estuario del Río Negro e incluso en el estuario de río Chubut, Chubut, Argentina. Ocasionalmente ha sido registrada en la Patagonia austral. En este trabajo se reporta la presencia de la especie en la bahía Puerto San Julián, Santa Cruz, Argentina. La identificación taxonómica de los ejemplares fue sustentada mediante caracteres morfológicos. La presencia de esta especie en territorios australes plantea incógnitas y motiva a realizar nuevos estudios sobre su dinámica y hábitos migratorios.
