All the named species from NSW are detailed here. There seems to be about 10 additional unnamed species occurring in the waters of the state. Most are deep water; two or three are similar to Aesopus plurisulcatus; another, from around 1000 m deep resembles Mitrella; and a few minute species are close to Retizafra.

The following species are listed as occurring in NSW by Iredale & McMichael (1962), but no NSW specimens can be found in the Australian Museum collection:

Mitrella abyssicola (Brazier, 1877);
Mitrella ligula (Duclos, 1840);
Mitrella puella (Sowerby, 1844).

The name Mitrella alizonae (Melvill & Standen, 1901) was used by Iredale & McMichael, but it is an incorrect identification for one of the deep water, undescribed species.
