Coleman 1911: 699; Fisher 1919: 355; Powell 1937: 78; Fell 1958: 13; Dartnall 1968: 23 (as Asterodiscus ).

Rowe 1977: 200 (as Asterodiscides ).

Comments. This species was identified based on its relatively stellate shape and the presence of enlarged superomarginals which are larger in size than the proximal superomarginals and most of the abactinal tubercles.

This is the first record of this species from New Caledonia and the third species of Asterodiscides from this region. Asterodiscides helenotus ( Fisher, 1913) and A. soelae Rowe, 1985 were documented from New Caledonia by Ameziane (2007).

Occurrence. South Australia , east to Kermadec Islands, New Caledonia. 14–792 m.

Material Examined. MNHN IE-2016-1550 (ex. EcAs 12238). Norfolk Ridge , New Caledonia, 23º41′S, 168º00′E, 237–550 m. Coll GoogleMaps . BATHUS 3 , CH 802 Bouchet , Richer, Warén. Coll. 27 Nov. 1993. 1 dry spec . R =2.3, r=1.3.
