==Description== ''Abbasites'' is small and subglobular with ribbing that divides high on its sides and which has an interruption on the venter that replaces the keel, generally characteristic of the Hammatoceratidae <ref name = Arkell>Arkell, Kummel, and Wright 1957.

==Classification== ''Abbasites'' was originally described by Sydney S. Buckman in 1921,<ref name = Arkell/><ref>[http://www.ubio.org/NZ/detail.php?uid=84&d=1 Abbasites in Nomenclator Zoologicus]</ref> with ''A. abbas'' as its type species, and was considered by some to be a subgenus of ''Erycites''. ''Abbasites'' was included in the Otoitidae, the ancestral family of the Stephanoceratoidea, according to Westermann (1965)<ref name = Imlay>Imlay, Ralph W . 1984.
