For the first time, a new species was scientifically described in 2008 [4] . Species epithet comes from lat. umbrosus . - "shady." The holotype is a sexually mature male 35.1 cm long, caught in the waters of Queensland ( ) at a depth of 530 m [5] .
These rays are endemic to the northeast coast of Australia . They are found in the upper part of the continental slope at a depth of 360 to 731 m [2] [3] .
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 36.9 cm and the disk width is 19.1 cm [2] [2] .
These stingrays lay eggs enclosed in a horn capsule with "horns" in the corners [1] . Males reach puberty with a length of 34.9 cm [2] .
These ramps are not the target fishing target. The International Union for Conservation of Nature has assigned the conservation status of βLeast Concernsβ [2] .
