A New Species of Nezumia (Gadiformes: Macrouridae) from Fieberling Guyot, Eastern North Pacific Ocean

Se describe una nueva especie de Nezumia del Pacífico Norte que parece endémica de la bioprovincia Seamount de Baja California, donde podría estar desde tiempos del mar de Tetis o haber llegado posteriormente desde el Pacìfico Indo-occidental.

The new species is distinguishable from all other Nezumia species chiefly on the basis of a high number of pelvic fin rays, a relatively high number of first dorsal fin soft rays, a steep blunt snout lacking scales ventrally, a relatively weak suborbital ridge, and a moderately long, thin barbel. Although possibly endemic to the Baja California Seamount Province, the new species appears to lack close relatives among the other Nezumia species of the eastern North Pacific Ocean. It might have arrived there either from a disjunct Tethyan distribution, thus retaining close relatives among the Atlantic Ocean species of Nezumia, or by way of stepping-stone dispersal from the Indowest Pacific Ocean.
