PETTIBONE I SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY • NUMBER 538 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.

Smithsonian Contributions to Zoology, number 538, 92 pages, frontispiece, 55 figures, 1993. Included in this report are new distribution records and descriptions of 44 species of Polynoidae distributed between two subfamilies: Lepidonotinae, with Hermenia verruculosa Grube and Lepidonopsis humilis (Augener); and Harmothoinae, with Subadyte pellucida (Ehlers), and three species and one new combination of Hololepidella Willey. The study includes a replacement of Malmgrenia Mclntosh, 1874 (= indeterminable) with Malmgreniella Hartman, 1967, emended, with a redescription of M. dicirra Hartman, 1967, the type species, and a review and revision of the species that have been referred to Malmgrenia, resulting in 13 new combinations (with 2 new synonyms) and 19 new species of Malmgreniella. In addition, three new genera are added, including Paragattyana, for P. micropoides (Augener), new combination, and P. intesi, new species; Rullieriella, for R. monoechinata (Rullier), new combination, with synonym Parahalosydna chryostictus Hutchings and Rainer, and Wilsoniella for W. furcosetosa (Loshamn), new combination. Most of the species show a more or less close association with other invertebrates, including echinoderms (ophiuroids, spatangoid echinoids, synaptid holothurians), coelenterates (hydrocorals), and other polychaetes (arenicolids, terebellids, and chaetopterids).

  • (Polychaeta) from the CANARY ISLANDS
    BULLETIN OF MARINE SCIENCE, 48(2): l8D-188, 1991 POL YNOIDAE (pOLYCHAETA) FROM THE CANARY ISLANDS M. C. Brito, J. Nunez and J. J. Bacallado ABSTRACT This paper is a contribution to the study of the family Polynoidae (Polychaeta) from the Canary Islands. The material examined has been collected by the authors from 1975 to 1989. A total of 18 species was found belonging to 8 genera: Gesiel/a (I), Po/ynoe (1), Adyte (I), Subadyte (I), Harrnothoe (11), A/entia (1), Lepidasthenia (1) and Lepidonotus (I). Ten species are new to this fauna and one, Harrnothoe cascabullico/a, is new to science. Furthermore, the genera Po/ynoe, Adyte and Lepidasthenia are recorded for the first time in the Canary Islands. The Polychaeta of the Canary Islands are enumerated in the provisional cata- logue of Nunez et al. (1984), in which are recorded 148 species, 12 of which belong to the family Polynoidae. Samples from the Canary coastline were examined and members ofPolynoidae studied. A total of 173 specimens was studied, belonging to 7 subfamilies, 8 genera, and 18 species, of which 9 species are recorded for the first time in the Canarian fauna. Worthy of note is the large number of species belonging to the genus Harmothoe (11), one of which, H. cascabullicola is new. METHODS The material examined was collected from 1975 to 1989, from 61 stations, at 45 localities on the Canary coasts (Fig. I). The list of stations, with their localities, types of substrate and collecting data are listed in Table I. The methods used in collecting depended on the type of substrate.

  • Role of Reef-Building, Ecosystem Engineering Polychaetes in Shallow Water Ecosystems
    diversity Review Role of Reef-Building, Ecosystem Engineering Polychaetes in Shallow Water Ecosystems Martín Bruschetti 1,2 1 Instituto de Investigaciones Marinas y Costeras (IIMyC)-CONICET, Mar del Plata 7600, Argentina; [email protected] 2 Laboratorio de Ecología, Universidad Nacional de Mar del Plata, FCEyN, Laboratorio de Ecología 7600, Argentina Received: 15 June 2019; Accepted: 15 September 2019; Published: 17 September 2019 Abstract: Although the effect of ecosystem engineers in structuring communities is common in several systems, it is seldom as evident as in shallow marine soft-bottoms. These systems lack abiotic three-dimensional structures but host biogenic structures that play critical roles in controlling abiotic conditions and resources. Here I review how reef-building polychaetes (RBP) engineer their environment and affect habitat quality, thus regulating community structure, ecosystem functioning, and the provision of ecosystem services in shallow waters. The analysis focuses on different engineering mechanisms, such as hard substrate production, effects on hydrodynamics, and sediment transport, and impacts mediated by filter feeding and biodeposition. Finally, I deal with landscape-level topographic alteration by RBP. In conclusion, RBP have positive impacts on diversity and abundance of many species mediated by the structure of the reef. Additionally, by feeding on phytoplankton and decreasing water turbidity, RBP can control primary production, increase light penetration, and might alleviate the effects of eutrophication

Figures highlighting important anatomical features associated with couplets in the key are provided. 2 INTRODUCTION The Caribbean region is one of the major coral reef zoogeographic provinces and a region of intensive human use of marine resources for tourism and fisheries (Aide and Grau, 2004). With the world-wide decline of coral reefs, and deterioration of shallow-water marine habitats in general, ecological and biodiversity studies have become more important than ever before (Bellwood et al., 2004). Ecological and biodiversity studies require identification of collected specimens, often by biologists not specializing in taxonomy, and therefore identification guides easily accessible to a diversity of biologists are necessary.

  • Two New Brittle Star Species of the Genus Ophiothrix
    Caribbean Journal of Science, Vol. 41, No. 3, 583-599, 2005 Copyright 2005 College of Arts and Sciences University of Puerto Rico, Mayagu¨ez Two New Brittle Star Species of the Genus Ophiothrix (Echinodermata: Ophiuroidea: Ophiotrichidae) from Coral Reefs in the Southern Caribbean Sea, with Notes on Their Biology GORDON HENDLER Natural History Museum of Los Angeles County, 900 Exposition Boulevard, Los Angeles, California 90007, U.S.A. [email protected] ABSTRACT.—Two new species, Ophiothrix stri and Ophiothrix cimar, inhabit shallow reef-platforms and slopes in the Southern Caribbean, and occur together at localities in Costa Rica and Panama, nearly to Colombia. What appears to be an undescribed species resembling O. cimar has been reported from eastern Venezuela. In recent years, reefs where the species were previously observed have deteriorated because of environmental degradation. As a consequence, populations of the new species may have been reduced or eradicated. The new species have previously been mistaken for O. angulata, O. brachyactis, and O. lineata. Ophiothrix lineata, O. stri, and O. cimar have in common a suite of morphological features pointing to their systematic affinity, and a similar pigmentation pattern consisting of a thin, dark, medial arm stripe flanked by two pale stripes. Ophiothrix lineata is similar to Indo-Pacific members of the subgenus Placophiothrix and closely resembles Ophiothrix stri. The latter is extremely similar to O. synoecina, from Colombia, and both can live in association with the rock-boring echinoid Echinometra lucunter. Although O. synoecina is a protandric hermaphrodite that reportedly broods its young externally, the new species are gonochoric and do not brood.
