The species was first scientifically described in 2005 [4] . The species is named after Professor Hajime Ishihar , who has devoted more than 25 years to the study of plate-branchial, in particular deep-sea rays. The species is known for only two individuals [2] . The holotype is a 123 cm long mature male caught off the coast of Western Australia ( ) at a depth of 2320β2350 m. Paratyp is an immature male 36 see, caught there [5] .
The range of these rays is fragmented; they live off the coast of Western Australia [2] . They are found at a depth of up to 2350 m [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. 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 123 cm [2] .
Embryos feed exclusively on yolk . These stingrays lay eggs enclosed in an elongated horn capsule [2] .
These ramps are not the target fishing target. Potentially by-catch during fishing with trawls and longlines. In the area, fishing is conducted at a depth of over 700 m. There are insufficient data to assess the conservation status of the species by the International Union for Conservation of Nature [2] .
