Pease (1860) described the genus Pterogasteron for two species collected in the Hawaiian Islands, Pterogasteron ornatum Pease, 1860 and Pterogasteron bellum Pease, 1860. No type species was indicated. Pease’s illustrations were published in Bergh (1881: pl. G, fig. 18–19), who transferred Pterogasteron ornatum Pease, 1860 to the genus Elysia, making it a homonym of Elysia ornata (Swainson, 1840), of which it is also a synonym according to Jensen (1992). Krug et al. (2016) restricted Elysia ornata (Swainson, 1840) to Atlantic waters and showed that there may be undescribed Indo-Pacific species, all members of the Elysia ornata clade.
