  • Discopyge castelloi sp. nov. (Torpediniformes, Narcinidae), a new species of electric rayfrom the Argentine Sea. A new species of electric ray of the family Narcinidae, Discopyge castelloi, is describedfrom the southwestern Atlantic off Argentina. Distinctive characters of the new species are the form of the body,the posterior position of pelvic fins and the manner as pelvic fins join the caudal peduncle, the morphology of thenasal curtain and the presence of small but apparently functional eyes. Discopyge castelloi is the fourth torpediniformspecies reported from the area. It appears to be very rare on the shelf, though the type locality is separated fromthat of the paratypes by seven latitude degrees. As in the case of Torpedo puelcha, it is probable that the newspecies has a normal habitat deeper than that of the available specimens.
