Notiax santarita, a new species of the Callianassidae (Decapoda, Thalassinidea) from the Beagle Channel, southernmost America

Seventeen specimens of Notiax santarita sp. nov. were collected in the Beagle Channel in southernmost Chile during the Joint Chilean-German-Italian "Victor Hensen" Campaign in 1994 and the Chilean expedition "Cimar Fiordo III" in 1997. These specimens are the first Callianassidae that are recorded south of 46 degree S in Chile and represent the second species of the genus Notiax found in America. This callianassid, herein described as a new species, has been compared with the second species of the genus, Notiax brachyophthalma, known from the Chilean and Argentine coasts.
