Genus Antarctus n. gen.

TYPE AND ONLY SPECIES. — Scyllarus mawsoni Bage, 1938 by present designation.

ETYMOLOGY. — From the Greek antarktikos (southern), latininized to antarcticus , shortened to provide the ending - arctus , based on the generic name Arctus De Haan, 1849 . The name is given to indicate that this is the most southern of the scyllarid genera, its range extending closest to the Antarctic.

DIAGNOSIS. — Carapace with rostral, pregastric, gastric and cardiac teeth. Abdomen without arborescent markings; somites II to IV each with a transverse groove and a median longitudinal carina. The tips of pleura II to IV are acute and directed somewhat back. Fourth segment of antenna with two strong oblique carinae; the inner of these traversing the segment from the base to the apex. The anterior margin of this segment with five to eight teeth, the inner two largest; the outer margin has two (or one) large teeth. The pereiopods 2 to 5 are slender, without fringes of long hairs. On the anterior margin of the thoracic sternum the two anterolateral teeth form a deep sharply V-shaped median incision.

DISTRIBUTION. — S and E coast of Australia from Eucla, Western Australia to Port Stephens, New South Wales.

REMARKS

A more extensive discussion of the type species will be given in a work in preparation by Dr John C. Yaldwyn.
