Originally Horologinella, subsequently (and now) Paucilobimorpha. Pestchevitskaya (2001, p.106; 2003, p.53) included this species in Horologinella but did not mention its transfer to Paucilobimorpha.
Holotype: Cookson and Eisenack, 1962a, pl.37, fig.10; Pestchevitskaya, 2001, pl.2, fig.16; Pestchevitskaya, 2003, pl.2, fig.4.
