A neotype specimen is designated for Chone acustica (Claparède, 1870) with a full description. The original descriptions of Chone arenicola Langerhans, 1880 and Chone collaris Langerhans, 1880, both from Madeira, did not include some details and incomplete or misleading information was provided, so both species are redescribed. Amendments to the description of Chone longiseta Giangrande, 1992 are also given together with the methyl green staining pattern of Chone usticensis Giangrande et al. 2006. Two new species are described: Chone gambiae sp. nov., from the Gulf of Naples and Chone dunerificta sp. nov., from the Gulf of Salerno. This study shows the distribution of Chone duneri Krøyer, 1856, and Chone filicaudata Southern, 1914, to be restricted to the Arctic seas and North Atlantic Ocean, respectively. Records from the Mediterranean Sea are found to be erroneous. Se designó el neotipo de Chone acustica (Claparède, 1870). Las descripciones originales de Chone arenicola Langerhans, 1880 y Chone collaris Langerhans, 1880, ambas de Madeira, no incluyen carácteres diagnósticos y la información proporcionada en otras contribuciones es incompleta, en este estudio ambas especies fueron redescritas. Se adicionaron carácteres diagnósticos a la descripción de Chone longiseta Giangrande, 1992, y se describió el patrón de tinción con verde de metilo de Chone usticensis Giangrande et al. 2006. Se describieron dos nuevas especies: Chone gambiae sp. nov., del Golfo de Nápoles y Chone dunerificta sp. nov., del Golfo de Salerno. Se restringió la distribución de Chone duneri Krøyer, 1856 para los mares del Ártico y Chone filicaudata Southern, 1914 para el Océano Atlántico Norte. Los registros de ambas especies para el Mar Mediterráneo son erróneos.
