  • Notopus Dorsipes (Linnaeus) in Singapore: First Record of the Brachyuran Superfamily Raninoidea (Crustacea: Decapoda) on the Sunda Shelf
    NATURE IN SINGAPORE 2012 5: 19–25 Date of Publication: 27 January 2012 © National University of Singapore NOTOPUS DORSIPES (LINNAEUS) IN SINGAPORE: FIRST RECORD OF THE BRACHYURAN SUPERFAMILY RANINOIDEA (CRUSTACEA: DECAPODA) ON THE SUNDA SHELF Martyn E. Y. Low1* and S. K. Tan2 1Department of Marine and Environmental Sciences, Graduate School of Engineering and Science University of the Ryukyus, 1 Senbaru, Nishihara, Okinawa 903-0213, Japan 2Raffles Museum of Biodiversity Research, National University of Singapore 6 Science Drive 2, Singapore 117546, Republic of Singapore (*Corresponding author: [email protected]) INTRODUCTION Recently, a brachyuran crab identified as Notopus dorsipes (Linnaeus, 1758), was found at Changi (north-east Singapore). This represents the first record of the superfamily Raninoidea de Haan, 1839, in Singapore and on the Sunda Shelf (Figs. 1, 2). The superfamily Raninoidea has a worldwide distribution and its members inhabit marine habitats from the intertidal zone to over 300 m deep (reviewed in Ahyong et al., 2009; see also Dawson & Yaldwyn, 1994). Fifty species of raninoids are currently assigned to 12 genera in six subfamilies (Ng et al., 2008). Notopus dorsipes belongs to a monotypic genus currently assigned to the subfamily Notopodinae Serène & Umali, 1972 (see Ng et al., 2008). Originally described as Cancer dorsipes by Linnaeus (1758), this species has had a confused nomenclatural history (see Holthuis, 1962). In order to stabilise the name Cancer dorsipes Linnaeus, Holthuis (1962: 55) designated a figure in Rumphius (1705: pl. 10: Fig. 3) as the lectotype of Notopus dorsipes (reproduced as Fig. 3). De Haan (1841) established the genus Notopus for Cancer dorsipes Linnaeus, the type species by monotypy.

  • How to Become a Crab: Phenotypic Constraints on a Recurring Body Plan

For over 140 years, convergent evolution of the crab-like body plan (with a wide and flattened shape, and a bent abdomen) at least five times in decapod crustaceans has been known as ‘carcinization’. The repeated loss of this body plan has been identified as ‘decarcinization’. We offer phylogenetic strategies to include poorly known groups, and direct evidence from fossils, that will resolve the pattern of crab evolution and the degree of phenotypic variation within crabs. Proposed ecological advantages of the crab body are summarized into a hypothesis of phenotypic integration suggesting correlated evolution of the carapace shape and abdomen. Our premise provides fertile ground for future studies of the genomic and developmental basis, and the predictability, of the crab-like body form.

  • Decapod Crustacea : Raninidae
    CAMPAGNES MUSORSTOM. I & II. PHILIPPINES, TOME 2 — RÉSULTATS DES CAMPAGNES MUSORSTOM. I & II. PHILIPPINES, 6 Decapod Crustacea : Raninidae Gary D. GOEKE * ABSTRACT Nine species of frog crabs of the family Raninidae were collected during the 1976 and 1980 MUSORSTOM cruises to the Philippines and the 1980 CORINDON II cruise in Makassar Strait. A proposed new genus, Lysirude (containing 3 species) is described and separated from the closely related genus Lyreidus. Five species (Raninoides hendersoni, R. personatus, Lyreidus tridentatus, L. stenops and Lysirude channeri) are represented by numerous specimens with far fewer specimens of Cosmonotus grayi, Notopoides latus, Lyreidus brevifrons and Lysirude grif- fini sp. nov. present. RÉSUMÉ Neuf espèces de Crabes de la famille des Raninidae ont été récoltées au cours des campagnes MUSORSTOM 1976 et 1980 aux Philippines et de la campagne CORINDON II dans le détroit de Macassar. Un nouveau genre Lysirude (avec trois espèces) est décrit et séparé du genre très proche Lyreidus. Cinq espèces (Raninoides hender­ soni, R. personatus, Lyreidus tridentatus, L. stenops et Lysirude channeri) sont représentées par de nombreux spé­ cimens, tandis que d'autres (Cosmonotus grayi, Notopoides latus, Lyreidus brevifrons et Lysirude griffini sp. nov.) ne comprennent qu'un nombre moins élevé d'échantillons. The Raninidae of the Philippines are a diverse group well represented in the MUSORSTOM col­ lections. Species of this fossorial group collected in the Philippines were most recently detailed by SERENE and UMALI (1972) and SERENE and VADON (1981). This contribution presents a systematic review of the Philippine species with an updated key to the recognized species of frog crabs known from the region.

The description of the morphological features of the species is given. Spanner crabs inhabit coastal waters of several coun- tries in the Indian and Pacific oceans, from the east coasts of southern Africa to Hawaii and the Great Barrier Reef. They prefer bare sandy areas and inhabit intertidal waters to depths more than 100m. They aggregate to spawn during the warmer months and mate at any stage in the moult cycle (Brown, 1986) and females store the sperm until the eggs are extruded.During spawning the females often bury themselves to incubate and protect the eggs. Large females produce at least 2 batches of eggs, each season with an average number of 1,20,000 per batch. The eggs remain attached to the female for 4 – 5 weeks before hatching (Brown, 1986). They pass through 8 larval stages during the following 5 to 8 (longest in higher latitudes) weeks of their life, and then they settle before metamorphosis to the recognizable spanner crab form Fig. 1. Ranina ranina landed at Pamban (Brown, 1986).

Proceedings of a sympo- sium at the Fifth International Crustacean Congress, Melbourne, Australia, 9–13 July 2001. Memoirs of Museum Victoria 60(1): 145–149. The primitive crabs consist of the Cyclodorippidae Ortmann, 1892; Cymonomidae Bouvier, 1897; Dromiidae de Haan, 1833; Dynomenidae Ortmann, 1892; Homolodromiidae Alcook, 1900; Homolidae de Haan, 1839; Latreilliidae Stimpson, 1858; Phyllotymolinidae Tavares, 1998; Poupiniidae Guinot, 1991; and Raninidae de Haan, 1841. The prim- itive crabs were transferred for the first time from the Brachyura to the Anomura by H. Milne Edwards (1832). Since then, they have been moved, individually or collectively, from the Anomura to the Brachyura and vice-versa with each successive revision. The high classification of both, Anomura and Brachyura, will not attain stability until the systemat- ic position of the primitive crabs is established on a firm basis. The question of whether the Podotremata, in whole or in part, belongs or not to the Brachyura is discussed herein from a cladistic perspective.

  • Phylogenetic Systematics of the Reptantian Decapoda (Crustacea, Malacostraca)
    Zoological Journal of the Linnean Society (1995), 113: 289–328. With 21 figures Phylogenetic systematics of the reptantian Decapoda (Crustacea, Malacostraca) GERHARD SCHOLTZ AND STEFAN RICHTER Freie Universita¨t Berlin, Institut fu¨r Zoologie, Ko¨nigin-Luise-Str. 1-3, D-14195 Berlin, Germany Received June 1993; accepted for publication January 1994 Although the biology of the reptantian Decapoda has been much studied, the last comprehensive review of reptantian systematics was published more than 80 years ago. We have used cladistic methods to reconstruct the phylogenetic system of the reptantian Decapoda. We can show that the Reptantia represent a monophyletic taxon. The classical groups, the ‘Palinura’, ‘Astacura’ and ‘Anomura’ are paraphyletic assemblages. The Polychelida is the sister-group of all other reptantians. The Astacida is not closely related to the Homarida, but is part of a large monophyletic taxon which also includes the Thalassinida, Anomala and Brachyura. The Anomala and Brachyura are sister-groups and the Thalassinida is the sister-group of both of them. Based on our reconstruction of the sister-group relationships within the Reptantia, we discuss alternative hypotheses of reptantian interrelationships, the systematic position of the Reptantia within the decapods, and draw some conclusions concerning the habits and appearance of the reptantian stem species. ADDITIONAL KEY WORDS:—Palinura – Astacura – Anomura – Brachyura – monophyletic – paraphyletic – cladistics.
