Entomocorus radiosus
Roberto E. Reis, and Thiago A.K. Borges

Новый вид сомовых из семейства Auchenipteridae из вернего течения реки Парагвай в Южной Америки.
ABSTRACT

The Neotropical auchenipterid catfish genus Entomocorus is reviewed and found to include four species widely distributed in lowland cis-Andean South America. Entomocorus benjamini is found in the Madeira River, E. gameroi occurs in the Orinoco River, E. melaphareus is from the lower Amazon River, and a previously undescribed species, E. radiosus, inhabits the upper Paraguay River. Entomocorus is diagnosed based on the shared presence of eight synapomorphies. Entomocorus radiosus is diagnosed by the unique combination of a long anal-fin base, 18–22 branched anal-fin rays, unpigmented pectoral and pelvic fins, and caudal fin hyaline, with distal half of dorsal and ventral lobes pigmented with black. All four species are diagnosed and illustrated, and a key to species is provided.
