Marcus, 1955 Habitat. Benthic. Depth. 0-15 m ( Schroedl and Hooker 2014 ). Type material. Not available. Distribution. Amphi-South American. On the Pacific side of South America, it extends from Callao (Peru, 12°S) to Comau Fjord (Chile, 42°S) ( Schroedl et al. 2005 ). On the Atlantic side it ranges from San Matias gulf (Argentina, 41°26'S) ( Cetra and Roche 2023 ) to Sao Paulo (Brazil, 21°S) ( Marcus 1959 ). Sampling/reporting sites. In Peru, it was reported in Callao (12°S), San Juan de Marcona (15°21′S), Islas Ballestas (13°44′S) ( Schroedl and Hooker 2014 ) and Independencia Bay (14°14'S) ( Uribe et al. 2013 ). In Chile, it was collected in Tocopilla (22°05'S), La Herradura (Coquimbo, 29°59′S), Tongoy (Coquimbo, 30°15′S) ( Fischer and Cervera 2005b ), Coliumo Bay (36°32'S) ( Schroedl 2003 ), Canal de Calbuco (41°45'S) ( Marcus 1959 ), and in Comau Fjord (42°22′S) ( Schroedl et al. 2005 ). In Argentina, it was collected in San Matias Gulf (Patagonia, 41°30′S) ( Cetra and Roche 2023 ). In Brazil, it was reported in Sao Paulo (21°21'S) ( Marcus 1959 ). Remarks. Molecular studies are needed to clarify the genetic identities of the populations on both sides of South America ( Schroedl 2003 ; Uribe et al. 2013 ). Family Hancockiidae MacFarland, 1923
