Scalispinigera oculata Hartman, 1967, originally placed in the polychaete family Scalibregmatidae, is transferred to
Lacydonia Marion & Bobretzky, 1875, in the family Lacydoniidae.
Scalispinigera oculata is the type species of the genus, and
Scalispinigera is consequently synonymized with
Lacydonia. The second species described in the genus,
S. cirrata Hartman & Fauchald, 1971, is likewise transferred to
Lacydonia. Based on examination of the types
Lacydonia antarctica Hartmann-Schroder & Rosenfeldt, 1988 is considered to be a junior synonym of
Lacydonia oculata (Hartman, 1967), new combination. The relationship of
L. oculata to
L. mikrops Ehlers, 1913 is discussed.
