Five new species of Nannosquilla from the northwestern Atlantic (Crustacea: Stomatopoda)

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 Zoo/ogy 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.

Observations on Nannosquilla, with descriptions of three new species from the northwestern Atlantic (Crustacea: Stomatopoda)

“…2). Other, more poorly represented and lessdistinctive species, such as N. baliops Camp and Manning, 1982, and N. whitingi Camp and Manning, 1982, are difficult to distinguish from their closely related congeners. However, as more specimens become available, our understanding of relationships within and among species of Nannosquilla increases.…”

“…In 1982, we described five new species of Nannosquilla from the northwestern Atlantic based on specimens that had accumulated in our respective institutions (Camp and Manning, 1982). While preparing that report, we examined most northwestern Atlantic specimens of related species deposited in the National Museum of Natural History, including two of the three known lots of N. antillensis (Manning, 1961), and noted differences between the single specimen of N. antillensis from waters off Yucatan, Mexico, and the series of specimens from St. John, Virgin Islands.…”

“…At the same time, we examined the holotype of N. hancocki (Manning, 1961) and noted characteristics that, in light of our in-creased understanding of the group, necessitated a redescription of that species. Finally, other specimens became available for study; one proved to be an additional undescribed species, another represented the second known record of N. adkisoni Camp and Manning, 1982, and the last represented the second known record of N. carolinensis Manning, 1970. In this paper, we discuss the generic placement of the single extra-American species currently assigned to Nannosquilla, update the generic definition, redescribe N. hancocki and N. antillensis, describe the new species, discuss variation in N. adkisoni, present the new record for N. carolinensis, and offer a key to the identification of western Atlantic species. This is also an opportune time to correct an error in the original description of Nannosquilla dacostai Manning, 1970. Contrary to the published description (Manning, 1970:101), that species lacks a mandibular palp, as do all members of the genus.…”

Morphology of stomatopod larvae from National Parks: Sistema Arrecifal Veracruzano and Arrecife Puerto Morelos, Mexico

“…Identification of the larvae followed current literature [Manning (1969;1995), Michel and Manning (1972); Rodrigues and Manning (1992); Ahyong et al (2014);and Antonio-Bueno (2015), for larvae of stomatopods in general; Townsley (1953), for Lysiosquilloidea Giesbrecht, 1910, Lysiosquilla Dana, 1852and Pseudosquillidae Manning, 1977Manning (1962) and Fornshell (2012), for Alima Leach, 1817;Pyne (1972) and Diaz (1998) for Squilla Fabricius, 1787;Morgan and Provenzano (1979), for Squilla empusa Say, 1818;Morgan and Goy (1987), for Neogonodactylus wennerae Manning and Heard, 1997;Provenzano and Manning (1978), for Neogonodactylus oerstedii (Hansen, 1895); García-Calzada (2013), for Nannosquilla adkisoni Camp and Manning, 1982 and Lysiosquilla scabricauda (Lamarck, 1818)]. The larvae were deposited in the National Collection of Crustaceans (CNCR) of the Institute of Biology of the Universidad Nacional Autónoma de México (UNAM).…”

“…Stomatopod larvae were identifi ed and classifi ed by their larval stage. We found representatives of three stomatopod superfamilies: the superfamily Gonodactyloidea Giesbrecht, 1910 was represented by Neogonodactylus oerstedii (Hansen, 1895), Neogonodactylus wennerae Manning and Heard, 1997, and Pseudosquillidae genus and species indeterminate; the superfamily Lysiosquilloidea Giesbrecht, 1910 was represented by Lysiosquilloidea genus and species indeterminate, Lysiosquilla sp., Lysiosquilla scabricauda (Lamarck, 1818) and Nannosquilla adkisoni Camp and Manning, 1982; the superfamily Squilloidea was represented by larvae of Alima neptuni (Linnaeus, 1768), Squilla spp., and Squilla empusa Say, 1818. We were able to identify and describe four stages of larval development for orcid.org/0000-0003-0531-5557…”
