†FAMILY LEPADIDAE DARWIN, 1852, AMENDED

Diagnosis: Monophyletic by molecular analyses. The morphological characterization is as for the superfamily. The subfamily Lepadinae Darwin, 1852 is hereby redefined and elevated to family status.

Comment: Species of Conchoderma von Olfers, 1814 are completely naked or near-naked forms and form a clade with a sister relationship to species of Lepas and Dosima . The monotypic Dosima is nested within species of Lepas . The plate arrangement of Hyalolepas Annandale, 1906 is basically the same as in Lepas, with the only difference being the extension of a long fork at the base of the carina, which reaches the basal margin of the scutum. At present, no molecular information is available for Hyalolepas; we tentatively allocated it inside Lepadidae owing to its high morphological affinity with Lepas .

Conchoderma von Olfers, 1814 (four species)

Dosima Gray, 1825 (two species)

Hyalolepas Annandale, 1906 (two species)

† Lepas Linnaeus, 1758 (Eocene–Recent) (17 species)

†† Pristinolepas Buckeridge, 1983 (Upper Oligocene to Middle Miocene) (four species)
