Decapod and Stomatopod Crustacea from Ascension Island, South Atlantic Ocean Raymond B. Manning and Fenner A. Chace, Jr. SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY • NUMBER 503 SERIES PUBLICATIONS OF THE SMITHSONIAN INSTITUTION Emphasis upon publication as a means of "diffusing knowledge" was expressed by the first Secretary of the Smithsonian. In his formal plan for the Institution, Joseph Henry outlined a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge." This theme of basic research has been adhered to through the years by thousands of titles issued in series publications under the Smithsonian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Contributions to Anthropology Smithsonian Contributions to Astrophysics Smithsonian Contributions to Botany Smithsonian Contributions to the Earth Sciences Smithsonian Contributions to the Marine Sciences Smithsonian Contributions to Paleobiology Smithsonian Contributions to Zoology Smithsonian Folklife Studies Smithsonian Studies in Air and Space Smithsonian Studies in History and Technology In these series, the Institution publishes small papers and full-scale monographs that report the research and collections of its various museums and bureaux or of professional colleagues in the world of science and scholarship. The publications are distributed by mailing lists to libraries, universities, and similar institutions throughout the world. Papers or monographs submitted for series publication are received by the Smithsonian Institution Press, subject to its own review for format and style, only through departments of the various Smithsonian museums or bureaux, where the manuscripts are given substantive review. Press requirements for manuscript and art preparation are outlined on the inside back cover. Robert McC. Adams Secretary Smithsonian Institution SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY • NUMBER 503 Decapod and Stomatopod Crustacea from Ascension Island, South Atlantic Ocean Raymond B. Manning and Fenner A. Chace, Jr. SMITHSONIAN INSTITUTION PRESS Washington, D.C. 1990 ABSTRACT Manning, Raymond B., and Fenner A. Chace, Jr. Decapod and Stomatopod Crastacea from Ascension Island, South Atlantic Ocean. Smithsonian Contributions to Zoology, number 503, 91 pages, 47 figures, 4 tables 1990.—Seventy four species of decapods and two species of stomatopods are recorded from Ascension Island. Of the decapods, 22 (30%) are amphi- Atlantic, 14 (19%) are endemic to the island, 19 (26%) occur in the central and western Atlantic only, and 14 (19%) are known only from the central and eastern Atlantic. Two new genera are recognized, Laleonectes, type species Portunus vocans A. Milne Edwards, and Tetrasqiulla, type species Lysiosquilla mccullochae Schmitt. Ten new species are described: Typton ascensionis, Gnathophyllum ascensione, Salmoneus setosus, Salmoneus teres, Processa packeri, Microprosthema inornatum, Odontozona anaphorae, Clibanarius rosewateri, Mursia mcdowelli, and Cataleptodius olsoni. Seven of the nine known shallow-water pantropical species of decapods and the only pantropical stomatopod are found at Ascension. Dardanus imperator, Euryozius sanguineus, Gecarcinus lagostoma, and Pachygrapsus loveridgei, are central Atlantic island species, known almost exclusively from Ascension or from Ascension and St. Helena. The percent of amphi-Atlantic fauna is about the same on Ascension (30%) and St. Helena (29%),but the percent of eastern Atlantic fauna (26% vs. 19%) and Indo-West Pacific fauna (23% vs. 16%) are higher at St. Helena; the component of western Atlantic fauna (26% vs. 14%) and endemic species (19% vs. 9%) are higher at Ascension. OFFICIAL PUBLICATION DATE is handstamped in a limited number of initial copies and is recorded in the Institution's annual report,Smithsonian Year.
