No recorded specimens have been reported northwards 45º S. The region where the type specimens of the Argentine skate were collected is dominated by sub-Antarctic cold-temperate waters with low salinity. These waters have a predominantly NNE flow and form the Patagonian Current (Brandhorst & Castello 1971). Range temperatures and salinities of the localities where the specimens were collected were 5.9-9.38ºC, and 33.24-33.64 ups, respectively. These physical characteristics agree with the Magellanic Biogeographic Province where the specimens have been captured (Ref. 79571). Díaz de Astarloa, J.M., E Mabragaña, R. Hanner and D.E.

Description: disc rhombic; snout greatly elongated; anterior margin of disc concave and posterior margin convex with rounded inner corner to level of pelvic fins; the tail is very slender and relatively long with a thin lateral tail fold; nostril flaps short, thick and tube-like; anterior nasal flap (nasal curtain) is well developed and fringed along distal margin; posterior nasal flap is poorly developed and smooth; mouth slightly arched; dorsal side of disc smooth except with a few small spinules scattered on tip of snout (one specimen with spinules also placed on both sides of eyes as well as in front of ocular region); the ventral side of disc, pelvics, claspers and tail are without dermal denticles except with a few small spinules scattered on tip of snout; midline of tail with 13 (10-24) small thorns, with oval bases and backwardly directed crowns. Coloration when fresh: upper surface of the disc plain purplish brown and margined with dark brown on pectoral and pelvic fins with no distinct ocelli or blotches; thorns are marked off pale milky-white pigment; lateral tail folds are creamy white pigment; dorsal fins are uniformly brown (Ref. 79571).
