    JOURNAL OF CRUSTACEAN BIOLOGY, 1(1): 28-50, 1981 STUDIES ON DECAPOD CRUSTACEA FROM THE INDIAN RIVER REGION OF FLORIDA. XX. MICROPANOPE BARBADENSIS (RATHBUN, 1921): THE COMPLETE LARVAL DEVELOPMENT UNDER LABORATOR Y CONDITIONS (BRACHYURA, XANTHIDAE) Robert H. Gore, Cindy Lee Van Dover, and Kim A . Wilson ABSTRACT The complete larval development of Micropanope barbadensis (Rathbun, 1921) , a small , western Atlantic, coral-inhabiting xanthid crab, is described and illustrated based on larvae reared in the laboratory. The species passed through 3 or 4 zoeal and one megalopal stage over a 24-32 day period at 20°e. At 15 and 25°C the larvae did not survive beyond the first or second stage, respectively. The duration of abbreviated and normal development periods is discussed. Zoeae of Micropanope barbadensis exhibit an antennal exopod:protopod ratio intermedia te in length and are therefore not assignable to any of the four categories delineated by Aikawa. A fifth category , Group E , is proposed. Criteria used to distinguish larvae of the genus Micropanope from other xanthid genera, as well as the taxonomic position of M. barbadensis. are considered. This is the fir st specie s in the genus Micropanope senSII {af o for which the complete larval development in the laboratory has been obtained. The genus Micropanope is a widely distributed, essentially tropical taxon of very small crabs, many species of which are associated with coral or coralline substrata. Rathbun (1930) listed about 9 or 10 species from the western Atlantic, but the systematics of the genus requires revision, so the ultimate number remains presently in doubt.

  • Decapoda (Crustacea) of the Gulf of Mexico, with Comments on the Amphionidacea
    •59 Decapoda (Crustacea) of the Gulf of Mexico, with Comments on the Amphionidacea Darryl L. Felder, Fernando Álvarez, Joseph W. Goy, and Rafael Lemaitre The decapod crustaceans are primarily marine in terms of abundance and diversity, although they include a variety of well- known freshwater and even some semiterrestrial forms. Some species move between marine and freshwater environments, and large populations thrive in oligohaline estuaries of the Gulf of Mexico (GMx). Yet the group also ranges in abundance onto continental shelves, slopes, and even the deepest basin floors in this and other ocean envi- ronments. Especially diverse are the decapod crustacean assemblages of tropical shallow waters, including those of seagrass beds, shell or rubble substrates, and hard sub- strates such as coral reefs. They may live burrowed within varied substrates, wander over the surfaces, or live in some Decapoda. After Faxon 1895. special association with diverse bottom features and host biota.

GORE3 ABSTRACT The larval development in the laboratory of Micropanope sculptipes. a western Atlantic deepwater xanthid crab which inhabits encrusted and coralline substrates, is completely described and illus- trated. Development proceeds from a prezoeal stage of brief duration through four zoeal stages and one megalopa stage. Survival of larvae was poor under experimental conditions of die! illumination, 36/,, salinity, and temperatures of 20°, 25°, and 25°-30°C. Development to megalopa occurred only at 25° C.

THOMA1*, DANIÈLE GUINOT2 and DARRYL L. FELDER1 1Department of Biology and Laboratory for Crustacean Research, University of Louisiana at Lafayette, Lafayette, LA 70504, USA 2Muséum national d’Histoire naturelle, Département milieux et peuplements aquatiques, 61 rue Buffon, Paris 75005, France Received 11 June 2013; revised 16 September 2013; accepted for publication 23 September 2013 Members of the brachyuran crab superfamily Xanthoidea sensu Ng, Guinot & Davie (2008) are a morphologically and ecologically diverse assemblage encompassing more than 780 nominal species. On the basis of morphology, Xanthoidea is presently regarded to represent three families: Xanthidae, Pseudorhombilidae, and Panopeidae. However, few studies have examined this superfamily using modern phylogenetic methods, despite the ecological and economic importance of this large, poorly understood group. In this study we examine phylogenetic relation- ships within the superfamily Xanthoidea using three mitochondrial markers, 12S rRNA, 16S rRNA, and cytochrome oxidase I (COI), and three nuclear markers, 18S rRNA, enolase (ENO) and histone H3 (H3). Bayesian and maximum-likelihood analyses indicate that the superfamily Xanthoidea is monophyletic; however, the families Xanthidae, Panopeidae, and Pseudorhombilidae, as defined by Ng et al., are not, and their representative memberships must be redefined. To this end, some relevant morphological characters are discussed. © 2013 The Linnean Society of London, Zoological Journal of the Linnean Society, 2014, 170, 86–109. doi: 10.1111/zoj.12093 ADDITIONAL KEYWORDS: COI – enolase – histone H3 – Panopeidae – phylogenetics – Pseudorhombilidae – 16S–12S–18S – Xanthidae.

    Proceedings of the United States National Museum SMITHSONIAN INSTITUTION • WASHINGTON, D.C. Volume 118 1966 Number 3536 DECAPOD CRUSTACEANS FROM ST. HELENA ISLAND, SOUTH ATLANTIC I By Fenner a. Chace, Jr. Senior Scientist, Department of Invertebrate Zoology Introduction As the site of Napoleon's last imprisonment and death, St. Helena is one of the best known solitary islands in the world, but much of its marme fauna has not been accorded the attention that it deserves. The island is an isolated volcanic peak 103^ miles long and 63^ mUes wide, situated slightly east of the mid-Atlantic Ridge at latitude 15°58' S. and longitude 5°43' W. The nearest point of exposed land is Ascension Island, about 800 miles to the northwest; southern Angola, roughly 1,200 miles to the east, is the closest point on the coast of West Africa, and Recife, BrazU, approximately 2,000 miles to the west-northwest, is the nearest South American shore. That St. Helena is reasonably old and has long been isolated is suggested by its numerous endemic fishes (Cunningham, 1910, and Cadenat and Marchal, 1963), mollusks (E. A. Smith, 1890), and echinoderms (Mortensen, 1933). Although considerable marine collecting has been done at St. Helena by Melliss, Cunningham, Mortensen, Colman, and the Reine- 623 . 624 PROCEEDINGS OF THE NATIONAL MUSEUM vol. ii8 Pokou (see Cadenat and Marchal), none of those collections, except the fishes and echinoderms, have been studied extensively. Melliss (1875) recorded the foUowmg six decapod crustaceans: Palaemon {'? forceps = Brachycarpus biunguiculatus) ; Palinurus, species ? (= IPanulirus echinatus); Scyllarus latus {= Scyllarides herklotsii); Pagurus bernhardus (I =Dardanus imperator) ; Dromia vulgaris {~D.
