On the basis of two specimens collected in Terra Nova Bay on February 1998 and 2000, adults of the recently described bathydraconid Acanthodraco dewitti Skora 1995 are documented for the first time in the Ross Sea. Meristic counts and morphometric measurements are provided and compared with those reported by Skora. The specimens were male and female in developing stage of gonad maturity. Differently from the related species Psilodraco breviceps, which is endemic of South Georgia, a probable circumantarctic distribution of A. dewitti is discussed.

Abstract
On the basis of two specimens collected in Terra Nova Bay on February 1998 and 2000, adults of the recently described bathydraconid Acanthodraco dewitti Skora 1995 are documented for the first time in the Ross Sea. Meristic counts and morphometric measurements are provided and compared with those reported by Skora. The specimens were male and female in developing stage of gonad maturity. Differently from the related species Psilodraco breviceps, which is endemic of South Georgia, a probable circumantarctic distribution of A. dewitti is discussed.File in questo prodotto:
