Material examined. Madagascar: one male ( FMNH 5732 ). One subadult female (cw 27.1 mm) ( FMNH 6709 ) .

Type locality. Nosy Be , Madagascar .

Distribution. Boreas uglowi is known only from three localities: Nosy Be, Nosy Komba and near Antsiranana city (Cumberlidge and Sternberg, 2002), all in the extreme north of Madagascar in Antsiranana Province (figures 3B, 5).

Conservation status. Boreas uglowi is restricted to the extreme north-western part of the island. It is known only from a few specimens, and little is known of its ecology. The specimens reported on here represent the first new material to be collected for more than 80 years. Its conservation status is extremely rare/highly endangered ( table 1). If this is a forest-dwelling species, then the locality on Nosy Be may be from the Réserve Naturelle Intégrale de Lokobe, which would afford some protection to this species.

Remarks. It has been brought to our attention that the genus name Boreas is preocuppied by Boreas Morris, 1980 , a genus of hippothoid bryozoan. A request to change the genus name of Boreas Cumberlidge and Sternberg, 2002 , which is a junior homonym, to Boreasamon Cumberlidge and Sternberg, 2002 is in preparation.
