Until recently, all papillated specimens of Pareledone were ascribed to the species Pareledone charcoti (Joubin, 1905): of which R aurorae (Berry, 1917) was considered a junior synonym. Re-examination of the papillated type material of Pareledone, coupled with extensive fishing over several years off the Antarctic Peninsula, has led to a revision of this position. Seven new species of papillated Pareledone are identified from the Antarctic Peninsula region. They, are identified by subtle taxonomic characters, such as the morphology and placement of their papillae: although traditional indices often fail to separate the species. Whilst apparently sympatric, there is some evidence of niche separation of these species with respect to depth. A key is provided for their identification.
