Taxonomy

It was first described in 1886 by Stuart Oliver Ridley and Arthur Dendy as Axinella lunaecharta,^[1][2] but in 1887, in their final report, they transferred it to the genus, Pseudaxinella.^[1][3] In 1917, E.F. Hallman revised some genera in the family, Axinellidae, and transferred it to the genus, Dragmacidon.^[1][4]
