Remarks. The very wide concept of this species proposed by, among others, Fauvel (1917, 1919), Hartman (1944) and Fauchald (1970), does not appear to be tenable. The specimens observed differ from the species as redescribed in Fauchald (1992) in that the number of teeth in MxII is relatively low (5–6 rather than 8–10). Furthermore, the structure of the left MxIV appears unusual in that the teeth are very small, nearly comb-like. Compared to material from the vicinity of the type locality ( Fauchald 1992), the posterior pectinate chaetae are narrow and have relatively few teeth.

Day & Hutchings (1979:115) reviewed previous records of this species from Australia. They listed L. bassensis   and L. torresiensis   as synonyms of L. antennata   . These three species were considered distinct from L. antennata   by Fauchald (1992) and are treated separately here. The three species resemble each other and other species in the same species group (C-2 sensu Fauchald 1992) in that all have yellow, tridentate subacicular hooks and pectinate branchiae continuing to the posterior end. In L. bassensis   the number of branchial filaments drops to a low of three and remains at that level for the rest of the branchiated part of the body; in L. antennata   and L. torresiensis   median chaetigers have a reduced number of filaments, sometimes as few as two, but the number increases again towards the posterior end. In L. bassensis   , the separation of the two peristomial rings is distinct on all sides and posterior notopodial cirri is strongly articulated; in L. antennata   and L. torresiensis   the separation is indistinct laterally and the articulations of notopodial cirri are not as strong. These three species differ in the shape of aciculae and subacicular hook. L. torresiensis   and L. antennata   also differ in the length of peristomial cirri, which reaches, respectively, anterior border of peristomium and mid anterior peristomial ring.

A third closely related species is L. aequabilis   , but it differs from L. antennata   in having cylindrical regular articulations in prostomial appendages and branchiae with a minimum of 12 filaments.

As the Australian Leodice cf. antennata   may be part of a global species complex, we are abstaining from a species description until additional material from other geographic regions is thoroughly examined.
