Of these, 27 species are recorded for ,the first time from the China Sea. The material for study was based on the collections made by the Institute of Oceanology, Academia Sinica.The Opisthobranchia fauna of Hainan may be summarized as follows:Ⅰ, The Opisthobranchia fauna of Hainan may be grouped into the following 5 components:(1) 3 circumtropical species: Aplysia (Varna) dactylomela, Dolabrifera dolabrifera, Notarchus (Stylocheilui) longicaudus.(2) 34 Indo-West-Pacific species: Pupa solidula, P. sulcata, Hydatina physis, Bulla ampulla, B. adamsii, Aliculastrum cylindricum, Retusa (Coelophysis) borneensis, Doridium lineolata, Aplysia (Varria) cornigera, Dolabella scapula, Placobranchus ocellatus, Euse-lenops (Euselenops) luniceps, Umbraculum sinicum, Hexabranchus marginatus, Gymnodoris striata, G. alba, Kalinga ornata, Glossodoris lineolata, G. hilaris, G. crossei, Casella atromarginata, Kentrodoris maculosa, Trippa intecta, Argus speciosus, A. tabulatus, A. laminea, Asteronotus cespitosus, Dendrodoris (Dendrodoris) nigra, D. (D.) tuberculosa, D. (D.) gemmacea, Aegires villosus, Phyllidia (Phyllidia) varicosa, P. (Phyllidella) pustulosa, Bornella digitata.(3) 10 West-Pacific species: Bulla vernicosa, Philine orientalis, Syphonota geogra-phica scripta, Dolabrifera fusca, Notarchus (Bursatella) leachii cirrosus, N. (Stylocheilus) risbeci, Doriopsis viridis, Gymnodoris inornata, Glossodoris marginata, Armina (Armina) semperi.(4) 1 endemic species of China: Armina (Linguella) punctilucens.(5) 14 species common to China Sea and Pacific coasts of Japan: Bulla orientalis, Akera constricta, Doridium gigliolii, Aplysia (Varria) kurodai, A. (V.) sagdmiana, Elysia (Elysia) trisinuata, Glossodoris multituberculata, G. aureopurpurea, Actinocyclus japoni-cus, Doriopsis aurantiaca, Homoiodoris japonica, Armina (Linguella) variolosa, A. (L.) babai, Bornella japonica.Ⅱ, As compared with those of adjacent waters the Opisthobranchia fauna of the southern coast of Hainan is closely allied to that of southern Japan.Ⅲ, The Opisthobranchia fauna of the southern coast of Hainan is more closely allied to that of Sisha Islands (Paracel Islands) than to that of its northern coast.Read More
