Bourdon (1976a: 219) stated that the type species of Parionella Nierstrasz & Brender à Brandis, 1923 was P . richardsonae Nierstrasz & Brender à Brandis, 1923. However, Nierstrasz & Brender à Brandis (1923) described two species ( P . richardsonae and P . elegans Nierstrasz & Brender à Brandis, 1923) in their new genus without indication of which was the type species. Therefore, the type species of Parionella was selected as P . richardsonae by the subsequent designation of Bourdon (1976a) .
