Remarks

Bircenna fulva Chilton, 1884 originally described from New Zealand, was well redescribed and illustrated from Chubut ( Kreibhom de Paternoster 1976) and from Santa Cruz ( Alonso 1980), along the Argentinean Atlantic coast. It is also widely found in Tierra del Fuego and in the Beagle Channel.
