Superfamily Paterinoidea Schuchert, 1893

Family uncertain

Remarks.—Originally assigned to the Paterinidae by Laurie (1986), the particular combination of characters displayed by Askepasma saw the genus reassigned to the Cryptotretidae ( Williams et al. 1998; Holmer et al. 2006) joining three other genera Cryptotreta Pelman, 1977 ; Aldanotreta Pelman, 1977 ; and Dzunarzina Ushatinskaya, 1993 . However, the relationship between each member of the Cryptotretidae is currently in a state of flux with the majority of genera based on only a few specimens that are inadequately figured and undoubtedly require revision ( Holmer et al. 2009). Dzunarzina may be synonymous with Askepasma (see Williams et al. 1998) and the presence of a ventral perforation in the type genus Cryptotreta may see the genus reassigned to another family. With the taxonomic uncertainties surrounding the Cryptotretidae , the family−level assignment of Askepasma is herein left open pending revision of the Siberian taxa.
