PROC. BIOL. SOC. WASH. 100(2), 1987, pp. 386-401 NOTES ON WESTERN ATLANTIC CALLIANASSIDAE (CRUSTACEA: DECAPODA: THALASSINIDEA) Raymond B. Manning Abstract. —SQnioT synonyms are reported for two species: Callianassa seti-manus (DeKay, 1844), for Callianassa atlantica Rathbun, 1926, and Calli-anassa grandimana Gibbes, 1850, for Glypturus branneri Rathbun, 1900. The genus Glypturus Stimpson, 1 866, is removed from the synonymy oi Callianassa Leach, 1814, and Glypturus acanthochirus Stimpson, 1866, is shown to be a senior synonym of Callianassa armata A. Milne Edwards, 1 870, from the Indo-West Pacific. Corallianassa, new genus, is recognized for Callianassa longiven-tris A. Milne Edwards, 1870, and Callianassa borradailei de Man, 1928. A list of the western Atlantic callianassids is presented. Studies on eastern American callianas-sids, initiated in 1982 at the Smithsonian Marine Station in Fort Pierce, Florida, have revealed that several changes are needed in the nomenclature of American callianas-sids. Senior synonyms exist for two names now in general use, Callianassa branneri (Rathbun, 1 900) and C atlantica Rathbun, 1926. The genus Glypturus Stimpson, 1866, long considered to be a synonym of Calli-anassa Leach, 1814, is recognized as a dis-tinct genus, and its type species, Glypturus acanthochirus Stimpson, 1866, originally described from the Florida Keys, appears to be conspecific with Callianassa armata A. Milne Edwards, 1870, from the Indo-West Pacific. A new genus is recognized for Callianassa longiventris A. Milne Edwards, 1870, from the western Atlantic and Cal-lianassa borradailei de Man, 1928, from the Pacific and Indian Oceans. All of these changes, supplemented with an up-to-date list of Western Atlantic callianassids, need-ed because of numerous recent changes in callianassid taxonomy, are presented here. Further, the forthcoming publication of a list of scientific and common names of deca-pod crustaceans of the United States by the American Fisheries Society also makes these name changes timely. This opportunity is taken to correct the name and authorship of the superfamily containing the Callianassidae erected by M. de Saint Laurent (1979:1395), who recog-nized the superfamily Axioidea Huxley, 1879, containing the families Callianassidae Dana, 1852, Axiidae Huxley, 1879, and Callianideidae Kossmann, 1880. According to Article 36(a) of the International Code of Zoological Nomenclature, third edition, 1985, a superfamily must bear the author-ship and date of the oldest family name in-cluded in it. A superfamily containing the three families listed above must be known as the Callianassoidea Dana, 1852. For now I prefer to follow Bowman and Abele (1982) and include these families in the superfam-ily Thalassinoidea Latreille, 1831. The Status of Gonodactylus setimanus DeKay, 1844 Two species of Callianassa, C atlantica Rathbun, 1926, and C biformis Biffar, 1971, are known to occur off' the extreme north-eastern coast of the United States. Calli-anassa atlantica is a sublittoral species, oc-curring from near shore to depths of 98-1 34 meters (Rabalais et al. 1981 ), and it has been recorded from localities between Nova Sco-
