|Distribution||Lower Cretaceous (Aptian), Alexander Island, Antarctica|
|Type||Notidisaster subitus Smith & Crame, 2012, p. 318 by original designation.|
|Species Included||Only the type species.|
|Classification and/or Status||Stem group Atelostomata (disasteroid), family uncertain - possibly a Collyritidae|
|Remarks||The subcentral peristome is very unusual and distinguishes this taxon from all other disasteroids except Cyclolampas and Pilematechinus. Cyclolampas is distinguished because it has well developed phyllodes of crowded pore-pairs adorally and Pilematechinus has a large conjunct apical disc.
