Reis, RE & TAK Borges, 2006. The South American catfish genus Entomocorus (Ostariophysi: Siluriformes: Auchenipteridae), with the description of a new species from the Paraguay River basin. Copeia 2006: 412â??421.
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, 18â??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.
