For the first time, a new species was scientifically described in 1870 [4] . The holotype is a female 19.3 cm long, caught in the waters of Argentina . These stingrays are often confused with Psammobatis scobina and Psammobatis normani (differ in almost round disk shape) [2] . Species epithet comes from lat. rudis - βrudeβ, βtoughβ.
These stingrays live in the waters of Argentina and Chile . They are found on the continental shelf and continental slope at a depth of 122β352 m [2] .
The broad and flat pectoral fins of these slopes form a rhombic disk with a wide triangular snout and rounded edges. On the ventral side of the disc are 5 gill slits, nostrils and mouth. The tail is longer than the disk. There are lateral folds on the tail. These skates have 2 reduced dorsal fins and a reduced caudal fin [1] . The maximum recorded length is 44 cm [2] .
These stingrays lay eggs enclosed in a horn capsule with "horns" in the corners [1] . Capsule length 5.7 cm, width 3.4 cm [3] .
These ramps are not the target fishing target. Caught in by-catch in the course of fishing for hake and black congrio . The data for the assessment of the conservation status of the species by the International Union for Conservation of Nature are insufficient [2] .
