DISTRIBUTION. — Several authors consider Antennella secundaria a cosmopolitan species ( Rees & Thursfield 1965; Millard 1975; Ryland & Gibbons 1991), with a preference for warm and temperate waters ( Schuchert 1997).

Our specimens were collected from New Caledonia, the Philippines and the Norfolk Ridge. The depth range at those localities was between 45 and 295 m.
