Description of Notoglanidium pembetadi new species (Siluriformes: Claroteidae) from the Kouilou-Niari River, Republic of the Congo

A new claroteid catfish, Notoglanidium pembetadi, is described from the Kouilou-Niari River basin (Republic of the Congo). This species can be distinguished from all other currently known Notoglanidium species as well as from the very similar Anaspidoglanis boutchangai, to which two specimens have erroneously been attributed in the past, by the following  combination of characters: II, 10–13 dorsal-fin rays; long dorsal-fin base (21.1–24.4% SL); short predorsal distance (30.1–33.5% SL); and short prepelvic distance (40.1–45.4% SL).

Revision of Notoglanidium and related genera (Siluriformes: Claroteidae) based on morphology and osteology

Apart from the well-demarcated genera Auchenoglanis and Parauchenoglanis, Auchenoglanidinae, one of the two subfamilies of the African catfish family Claroteidae, suffers from poor resolution at the generic level. For the remaining genera, Notoglanidium, Liauchenoglanis, Platyglanis and Anaspidoglanis, generic discriminations are rudimentary. In addition, several included species are poorly defined and barely represented in scientific collections. Until now, no study has included morphological data for all currently known species, and for many species osteological data were non-existent. Molecular data for most species are lacking as well. Here, a comprehensive account of the morphology and osteology is given of all species included in these four genera. Using computed tomography (CT scanning) as well as clearing and staining, osteological characters were combined with biometric, meristic and other morphological data to revise the status of these genera and included species. Morphological and osteological data, submitted to a phylogenetic analysis, agree with metric and meristic data that all Liauchenoglanis, Platyglanis and Anaspidoglanis cannot be discerned from Notoglanidium; their genus and type species descriptions fail to be distinguished from Notoglanidium. Here their synonymy is proposed, resulting in a single valid genus, including nine species of which the validity is confirmed. A key to the genus and included species, as well as a diagnosis and description for each of them, are provided.

A new distinctively banded species of Panaqolus (Siluriformes: Loricariidae) from the western Amazon Basin in Peru

Panaqolus albivermis is described as a new species based on four specimens from the San Alejandro River, a tributary of the upper Ucayali River in central Peru. Panaqolus albivermis is diagnosed from all other Panaqolus except P. maccus by having head, body, and fins with widely separated small white to yellow spots, vermiculations, and/or thin oblique bands on a black base (vs. exclusively small white to yellow spots on a black base in P. albomaculatus, generally broad oblique bands of alternating light to dark brown in P. changae, P. gnomus, P. purusiensis, and a uniformly dark gray to black body color in P. dentex, P. koko, and P. nocturnus); P. albivermis can be diagnosed from P. maccus by having a black base color (vs. brown), by having parallel dentary tooth cups (vs. acute intermandibular tooth cup angle), and by having a larger known adult body size (95.8 mm SL vs. 84.8).

 

Would love copies of all of these if possible.
