Taxonomic history

The species was first described, then named as ''Amphorina pallida'' by Charles Eliot. Later it became poorly understood, then rarely known. It was rediscovered and redescribed in 2002 and placed it in the genus '' Cuthona''.Ortea, J., L. Moro, and M. Caballer. 2002. ''Redescripción de Cuthona pallida (Eliot, 1906) (mollusca: nudibranchia) un pequeño eolidáceo de las islas de Cabo Verde y Canarias.'' Revista de la Academia Canaria de Ciencias 13 (4): 123-132. Recently, a DNA phylogeny of the former family Tergipedidae resulted in most species of '' Cuthona'' being transferred to the genus ''Tenellia'', including ''Cuthona pallida'' which became ''Tenellia pallida''.Cella, K; Carmona Barnosi, L.; Ekimova, I; Chichvarkhin, A; Schepetov, D; Gosliner, T. M. (2016)
