Revision of Chloeia Savigny in Lamarck, 1818 (Annelida, Amphinomidae)

Chloeia Savigny in Lamarck, 1818 is the largest genus in the Amphinomidae by including more species than other genera. Members of Chloeia species thrive in mixed substrates or sediments, mostly in tropical waters, and rarely reach deep water, or cold-temperate environments. A recent revision dealt with the species from tropical American seas and resulted in the redescription of five species, and the description of two other new ones. The objective for this additional contribution was to revise type and non-type specimens deposited in 12 of the largest world collections, and by applying a slightly modified approach from the precedent revision. Species were grouped herein after the type of branchiae, the first chaetiger with branchiae, and the dorsal pigmentation pattern. The results include the redescription of 16 species, with C. flava (Pallas, 1766) and C. fusca M'Intosh, 1885 being restricted, and three others reinstated: C. incerta de Quatrefages, 1866; C. fucata de Quatrefages, 1866, and C. pulchella Baird, 1868; 10 species are regarded as indeterminable: C. ancora Frickhinger, 1916; C. bengalensis Kinberg, 1867; C. candida Kinberg, 1857; C. egena Grube, 1855; C. furcigera de Quatrefages, 1866; C. macleayi Haswell, 1879; C. malaica Kinberg, 1867; C. nuda de Quatrefages, 1866; C. quatrefagesii Baird, 1868; and C. rupestris Risso, 1826. Further, 10 recently described species are being diagnosed and compared to their most similar species, but not redescribed; and 17 species are newly described: C. amoureuxi sp. n. from Madagascar, C. bemisae sp. n. from The Philippines, C. boucheti sp. n. from Indonesia, C. fauveli sp. n. from the Bay of Bengal, C. fiegei sp. n. from the Red Sea, C. gesae sp. n. from the Northeastern Atlantic, C. gilleti sp. n. from Western Africa, C. hutchingsae sp. n. from Australia, C. keablei sp. n. from Papua New Guinea, C. mezianei sp. n. from Western Africa, C. murrayae sp. n. from Australia, C. piotrowskiae sp. n. from The Philippines, C. poupini sp. n. from the French Polynesia, C. richeri sp. n. from New Caledonia, C. slapcisnkyi sp. n. from The Philippines, C wangi sp. n. from The Philippines, and C. zibrowii sp. n. from the French Polynesia. Keys to all archinomin genera and to all species of Chloeia are also included.
