Although no specimens have been located to date from the Rio Grande of New Mexico, it is believed the new species formerly occurred there because it is known as far upriver as El Paso, Texas. There is archaeological evidence of the new species' former occurrence in the Pecos drainage of New Mexico and there are exotic occurrences of this species from the Gila River of New Mexico. The new catfish closely resembles I. lupus but differs in possessing a heavy set body, deeper caudal peduncle, broader head and shorter dorsal and pectoral spines.
