High-count species of the stomiid fish genus Astronesthes from southern Subtropical Convergence region : two new species and redescription of Cryptostomias (Astronesthes) psychrolutes

Abstract

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.

Reproductive Ecology of Dragonfishes (Stomiiformes: Stomiidae) in the Gulf of Mexico

“…Stomiid specimens were selected for reproductive analysis as they became available during a large-scale, quantitative taxonomic analysis program. Specimens were identified using the keys of Gibbs ( ,b, 1969, Morrow (1964a,b,c), Morrow and Gibbs (1964), Barnett and Gibbs (1968), Goodyear and Gibbs (1969), Gibbs et al (1983), Gomon and Gibbs (1985), Gibbs and McKinney (1988), Sutton and Hartel (2004), Kenaley and Hartel (2005), Kenaley (2007), and Flynn and Klepadlo (2012). Species were measured to the nearest 0.1 mm standard length (SL) and total wet weights were recorded to the nearest 0.01 g. Entire gonads were removed and the wet weight recorded to the nearest 0.001 g. All gonads were stored in 70% ethanol for at least 1 week prior to histological preparation.…”

Zoogeography and systematics of the lanternfishes of the genus Nannobrachium (Myctophidae:Lampanyctini)

“…Parin et al (1974) recognized the subtropical affinities of some species in the South Atlantic Temperate Region and included them in what was called the Peripheral Central or Subtropical pattern. There is, however, considerable confusion, as Krefft (1976) and Gibbs and McKinney (1988) pointed out, because some species in the Subantarctic Water Mass are confined to its northernmost edges, i.e., the southern part of the Subtropical Convergence (STC), whereas other species occur in the STC and extend to the north and south of it, and still other species have their southern limit in the STC but are primarily found to the north in subtropical waters. Krefft (1976) discussed those species mentioned by Parin et al (1974) and gave examples of several other species as better fitting a "Convergence Pattern" (Krefft, 1976, fig.…”

“…Hulley (1981), however, considered the Atlantic South Temperate pattern to be broader in scope, consisting of a Convergence Subpattern and a Subantarctic Subpattern. Gibbs and McKinney (1988) considered that any species that mainly occurred between 35°S-45°S to have convergence distributions even if specimens also had been captured to the north or south of those limits. Boundaries for the South Atlantic and South Indian Temperate regions were set following the suggestions of Richard Backus (pers.…”
