Eschmeyer Califortiio Academy oj Sciences San Francisco, California 94118 Introduction of about The scorpionfishes, family Scorpaenidae, comprise a diverse group of 350 valid species. The family is best represented in shallow waters tropical seas, but important groups occur at high latitudes, particularly in the North Indo- Pacific Ocean; the greatest diversity is present in the tropical waters of the Pacific. Besides the commercially important species, some fishes of the family have received much attention because of the presence of toxic substances associ- our of ated with fin spines. Despite the interest in scorpionfishes, understanding world. the systematic status of the species is poor for most areas of the The present account deals with Atlantic species. Western Atlantic species which I have not treated earlier (Eschmeyer, 196Sa, b; Eschmeyer and Collette, all western 1966; Eschmeyer and Bailey, in press) are studied in most detail, but in North Atlantic species are mentioned and are included the keys (except references, Atlantic species of the genus Sebastes). Pertinent additional material, the or comments are given for some species treated in my earlier papers. Of those from the Gulf of Guinea are species occurring in the eastern Atlantic, given most attention, based on collections by the Institute of Marine Sciences, the Guinean Trawling Survey, and the United States Fish and Wildlife Service. and islands of St. Other species from the eastern Atlantic, Mediterranean Sea, 1 Contribution no. 1068 from the Marine Laboratory, Institute of Marine Sciences, University of Miami. Florida. [1] 2 CALIFORMA ACADEMY OF SCIENCES [Occ. Papers Helena, Ascension, and Tristan de Cunha are included, except North Atlantic species of Sebastes. Fifty-eight species in 11 genera are recognized; this includes one western Atlantic species of doubtful validity. Two species are treated as composed of two subspecies. In the eastern Atlantic the species occurring in the Mediter- ranean Sea and adjacent parts of the Atlantic deserve additional study, partic- ularly in regard to distribution and early literature. The most comprehensive accounts of eastern Atlantic scorpionfishes are those by Norman {1935a), Fowler (1936), Cadenat (1945), and Boutiere (1958). Recently several species have been described as new from the eastern Atlantic: Scorpaenodes arenai Torchio 1962a, Scorpaena gaillardac Roux 1954 (=5. stcphanica), and Scor- paena folgori Postel and Roux 1964 (here placed in Neomerinthe). Eschmeyer and Collette (1966) reported Ectreposebastes imus from the Gulf of Guinea and the western Atlantic. Wheeler and Eschmeyer (1968) removed Helicolenus microphthalmus from the Atlantic fauna. The supposed western Atlantic species Scorpaena microlcpis Gunter was found (Eschmeyer and Bailey, in press) to have been described from a specimen of the eastern Pacific species 5. guttata which had incorrect locality data. A new subgenus and three new species are described in the present paper. The scorpionfishes found in the Atlantic Ocean belong to the more generalized subfamilies. Zoogeographically, several distributional patterns are evident. Comparison of species on both sides of the Atlantic shows that the deeper the species lives the greater the likelihood that it has a close relative on the opposite side of the Atlantic or occurs on both sides of the Atlantic. The genera containing shallow-water species show more endemism. In the genus Sebastes (broadly defined), the single species occurring in the extreme South Atlantic has affinities with the small South American Pacific fauna which in turn probably arose from ancestors which were able to move south along the tropical Central American coast; the presence of three species of Sebastes in the extreme North Atlantic is most easily explained by a trans-Artie origin. A few of the warm-water genera are so far known only from the Atlantic, but most are represented in the Indian and Pacific oceans. Some world-wide tropical and south-temperate genera are more speciose in the Atlantic than in other areas; in some cases this may be a result of more collection and study of the Atlantic fauna. Species of the western Atlantic are given first within each genus, and in most cases the sections on comparisons in each species' account deal mainly with species of the same genus from the same side of the Atlantic. Major com- parisons of the faunas and comments on zoogeograjjhy are given in a separate section. The key is divided into two parts, the first for western Atlantic species and the second for species occurring in the eastern Atlantic and islands of Saint Helena, Ascension, and Tristan da Cunha. No. 79] ESCHMEYER: ATLANTIC SCORPIONFISHES 3 Acknowledgments Specimens from the eastern Atlantic were obtained from several sources. Many came from the Pillshury collections in the (iulf of (iuinea. My participa- tion in the two Pillsbury cruises off West Africa was supported by the University of Miami Deep-Sea Biological Program sponsored by the National Geographic Society. Operation of the Pillsbury was financed by a biological ship-time grant from the National Science Foundation. Additional specimens are from the Guinean Trawling Survey in the Gulf of Guinea (through Frank J. Williams), collections by Bruce B. Collette on Guinean Trawling Survey 1, and from col- lections by the United States Fish and Wildlife Service research vessel Geronimo; some William J. Richards (Tropical Atlantic Biological Laboratory) provided specimens collected by the R/V Geronimo. Julio Rodriguez-Roda (Institute de Investigaciones Pesqueras, Cadiz, Spain) generously loaned specimens reported by Cervigon (1960) from Mauritania; Fernando Cervigon provided additional information. J. Blache (Institute Fundamental D'Afrique Noire, Goree, Sene- gal) loaned specimens of Scorpaenodes ajricanus. Edward C. Raney (Cornell University) loaned specimens collected by Gilbert Bane in the Gulf of Guinea. Donald P. de Sylva (Institute of Marine Sciences) provided color slides of two species from the Azores. A loan of specimens from the British Museum (Natural History) was through the generosity of Alwyne C. Wheeler and P. Humphrey Greenwood. Specimens from the western Atlantic were from collections made by the United States Fish
