CEP 20940-040 Rio de Janeiro, Brazil Received 29 May 2013; revised 9 October 2013; accepted for publication 9 October 2013 The family Ischyroceridae is analysed herein by cladistic methods based on morphological characters, using both PAUP 4.0b and TNT. The data matrix of 41 characters x 32 terminal taxa was constructed using DELTA. Based on the results, we comment on the phylogenetic relationships of certain genera and their synapomorphic characters, also discussing the phylogenetic position of M y e rsiu s gen. nov., which appeared as the sister group oí Bathyphotis. In addition, Pseudischyrocerus crenatipes is removed to Bathyphotis, for which a new diagnosis is provided. A taxonomic study with the Ischyroceridae collected on the continental slope (depth, 700-2000 m) in the Campos Basin (20.5-24°S, 4(U41°W) was also performed. Samples were collected in November-December 2002 and July-August 2003 using a box core device. As a result, a new genus and eight new species are described: Bonnierella campensis sp. nov., Bonnierella laurensi sp. nov., Myersius denticaudatus gen. et sp. nov., Notopoma lowryi sp. nov., Notopoma teresae sp. nov., Pseudericthonius bousfieldi sp. nov., Pseudericthonius concavus sp. nov., and Pseudischyrocerus caecus sp. nov. The genus Bonnierella is recorded for the first time from Brazilian waters, and the subspecies Bonnierella linearis linearis and Bonnierella linearis californica are elevated to species rank. Keys to the genera of Ischyroceridae used in the cladistic analysis and the world species oí Notopoma are given. © 2014 The Linnean Society of London, Zoological Journal of the Linnean Society, 2014, 170, 34^85. doi: 10.1111/zoj. 12099 ADDITIONAL KEYWORDS: Campos Basin - cladistic analysis - Corophiidea - deep sea - Ischyroceridae - new species.

As a result of this project, two books proposed a new classification for the corophioideans were published in which 144 crustaceans were based on a morphological cladistic analysis, where listed (Serejo et al., 2010). Several taxonomic studies the suborder Corophiidea was erected. This suborder with Decapoda, Isopoda, and Tanaidacea from the comprised two infraorders: the Corophiida, earlier OCEANPROF have been published (e.g. Cardoso & placed within the suborder Gammaridea, and the Serejo, 2007; Albuquerque & Costa, 2008; Larsen, Caprellida, previously treated as a separate suborder.

Both species share a posterodistal lobe on the article 2 in male pereopod 5, which only E. pugnax pos- sesses in all the Ericthonius species described. The new species is very similar to the latter species in the morphological characters and the general coloration in life. However, the new species is dis- tinguishable from the latter species by the relatively larger eyes, the relatively slender peduncles of antennae, the convex posterior edge of telson between spinulose lobes (straight or concave in E. pugnax), and the distal edge of article 6 of gnathopod 2 in the hyper-adult male having a distinct incision (such an incision is absent in E. pugnax). In addition, the habitat preference is also differ- ent between the two species; E. convexus occurs on sandy-mud bottom, whereas E. pugnax inhab- its under rocks in the intertidal zone and among seaweeds in the shallow sea. Key words : Amphipoda, Ischyroceridae, Ericthonius, new species, Japan.

Griffiths* Department of Biological Sciences & Marine Research Institute, University of CapeTown, Rondebosch, 7700 South Africa E-mail: [email protected] (with 13 figures) Received 25 June 2013. Accepted 23 August 2013 Three species of marine Amphipoda, Peramphithoe africana, Varohios serratus and Ceradocus isimangaliso, are described as new to science and an additional 13 species are recorded from South Africa for the first time. Twelve of these new records originate from collecting expeditions to Sodwana Bay in northern KwaZulu-Natal, while one is an introduced species newly recorded from Simon’s Town Harbour. In addition, we collate all additions and revisions to the regional amphipod fauna that have taken place since the last major monographs of each group and produce a comprehensive, updated faunal list for the region. A total of 483 amphipod species are currently recognized from continental South Africa and its Exclusive Economic Zone . Of these, 35 are restricted to freshwater habitats, seven are terrestrial forms, and the remainder either marine or estuarine. The fauna includes 117 members of the suborder Corophiidea, 260 of the suborder Gammaridea, 105 of the suborder Hyperiidea and a single described representative of the suborder Ingolfiellidea.

  • 1 Amphipoda of the Northeast Pacific (Equator to Aleutians, Intertidal to Abyss): IX. Photoidea
    Amphipoda of the Northeast Pacific (Equator to Aleutians, intertidal to abyss): IX. Photoidea - a review Donald B. Cadien, LACSD 22 July 2004 (revised 21 May 2015) Preface The purpose of this review is to bring together information on all of the species reported to occur in the NEP fauna. It is not a straight path to the identification of your unknown animal. It is a resource guide to assist you in making the required identification in full knowledge of what the possibilities are. Never forget that there are other, as yet unreported species from the coverage area; some described, some new to science. The natural world is wonderfully diverse, and we have just scratched its surface. Introduction to the Photoidea Over more than a century the position of the photids has been in dispute. Their separation was recommended by Boeck (1871), a position maintained by Stebbing (1906). Others have relegated the photids to the synonymy of the isaeids, and taxa considered here as photids have been listed as members of the Family Isaeidae in most west coast literature (i.e. J. L. Barnard 1969a, Conlan 1983). J. L. Barnard further combined both families, along with the Aoridae, into an expanded Corophiidae. The cladistic examination of the corophioid amphipods by Myers and Lowry (2003) offered support to the separation of the photids from the isaeids, although the composition of the photids was not the same as viewed by Stebbing or other earlier authors. The cladistic analysis indicated the Isaeidae were a very small clade separated at superfamily level from the photids, the neomegamphopids, and the caprellids within the infraorder Caprellida.

  • Comments on Corophi
    Comments on Corophioid amphipods for LH dcadien 30August04 II. Ischyrocerids Family Ischyroceridae rd The ischyrocerids, like the ampithoids you will meet later, all have distinctive 3 uropods. Both the inner and outer rami bear embedded terminal spines whose fine dentition is of value in specific determination. They are clearly corophioids based on their eyes, which are usually relatively large and range from obtusely triangular to rectangular to oval to round. They also show the same ontogenic changes in relative strength of gnathopods discussed above in isaeid; the male strongly, and the female weakly. They are tubicolous, and bear spinning glands and modified dactyls for the extrusion of amphipod silk. We have nine genera from this family represented in the SCB; Cerapus, Ericthonius, Ischyrocerus, Jassa, Microjassa, Neoischyrocerus, Parajassa, Ventojassa, and the deep water Bonnierella. There is not currently a key available to separate them all. I will attempt to provide one below. Key to the genera of Ischyroceridae in the NEP (modified from J. L.

Three new species of ischyrocerid amphipods in the genus Cerapus (C. bundegi, C. murrayae, and C. volucola) are described from Australia and Papua New Guinea. Although these species have all of the morphological characteristics of Cerapus, they differ from other species in the genus in the construction of their tubes which are wrapped and parchment-like and sometimes elaborately covered with pieces of cut algae and seagrasses.

ZooKeys 730: 151–155. https://doi.org/10.3897/zookeys.730.22169 Abstract A response is given to criticisms in a recent paper of the validity of the amphipod suborder Senticaudata. The tacitly assumed status of truth implied in some molecular higher phylogenies is called in to question. Keywords Amphipoda, classification, phylogeny, Senticaudata Introduction The suborder Senticaudata was established by Lowry and Myers (2013) based on a number of character states, but primarily on the important synapomorphy of api- cal robust setae on the rami of uropods 1 and 2. This character occurs in nearly 100 families and more than 5,000 species which form the suborder. The Senticaudata is recognised by the WoRMS online database and is cited by most taxonomic papers reporting on taxa in the group.
