Abstract
The genus Coronium Simone, 1996 currently includes five Recent species: C. acanthodes (Watson, 1882), the type species C. coronatum (Penna-Neme and Leme, 1978), C. wilhelmense (Ramírez-Bohme, 1981), C. oblongum Simone, 1996 and C. elegans Simone, 1996. All are known to live off South America, from Brazil to Chile. Simone (1996) included three species in Coronium (C. coronatum, C. oblongum and C. elegans). He also illustrated drawings of the protoconchs, opercula, radula and details of the animal. Although C. acanthodes was originally included in Trophon (Watson, 1882) and C. coronatum in Columbarium (Penna-Neme and Leme, 1978), the species are undoubtedly close to each other and belong to a common muricid genus as demonstrated by Pastorino & Penchaszadeh (2009). To our knowledge there are no fossil taxa known. With the exception of C. wilhelmense described from Chiloé Island, at 41°51'4" S, 74°30'5", included in Coronium by Houart & Sellanes (2006) and of C. acanthodes described from West Patagonia, at 50°8'30"S, 74°'4 W, no other species of Coronium are known to be living off Chile.
