  • From the Southeast Australian Coast, with Comments on the Distribution and Habitat Preferences of Chondropodinae
    Muvi schmallenbergi gen. nov., sp. nov. (Crustacea, Tanaidacea) from the southeast Australian coast, with comments on the distribution and habitat preferences of Chondropodinae Piotr Jóźwiak and Magdalena Błażewicz Department of Invertebrate Zoology and Hydrobiology, Faculty of Biology and Environmental Protection, University of Łódź, Łódź, Poland ABSTRACT Based on material collected from the shelf off southeast Australia (offshore of Portland), a new genus and new species, Muvi schmallenbergi gen. nov., sp. nov., of the tanaidacean family Metapseudidae, is described. Muvi is distinguishable from other genera within the subfamily Chondropodinae by having equally long antennular flagella. It also differs from other Chondropodinae by a combination of characters such as eyelobes with a group of visual elements, rostrum with smooth lateral edges, pereonites with lateral processes and pleotelson lacking lateral process, antennule article-1 with a single apophysis, maxillule inner lobe well-developed, labial palp bearing three distal setae, cheliped exopod well-developed and setose, pereopod-1 coxa with distinct apophysis, pleopods in five pairs, and uropod basis without apophysis. The genus Deidamiapseudes Sganga & Roccatagliata, 2016 is moved from Chondropodinae (Metapseudidae) to Apseudoidea incertae sedis. An identification key for the genera within Chondropodinae is given, and their distribution is discussed.

  • Marsupial Brood Care in Cretaceous Tanaidaceans Alba Sánchez-García 1, Xavier Delclòs 1, Michael S
    www.nature.com/scientificreports OPEN Marsupial brood care in Cretaceous tanaidaceans Alba Sánchez-García 1, Xavier Delclòs 1, Michael S. Engel 2,3, Graham J. Bird4, Vincent Perrichot 5 & Enrique Peñalver 6 Received: 2 December 2016 Parental care in animal evolution has long fascinated biologists, but tracing this complex of behavioural Accepted: 9 May 2017 repertoires is challenging, as these transitory states often leave no corporeal traces as fossils. Among Published: xx xx xxxx modern invertebrates, the tanaidaceans (Malacostraca: Peracarida), a lineage of marsupial crustaceans, show an interesting variety of brooding strategies. Here we report on fossil tanaidaceans from the Cretaceous of Spain and France that provide conclusive evidence for marsupial care of brood-offspring. Two exceptionally preserved female specimens of Alavatanais carabe and A. margulisae from Late Albian Peñacerrada I amber (Spain) possess four pairs of rudimentary oostegites, indicating formation of a marsupium. From Recent data, given the taxonomic distribution of a marsupium of four pairs of oostegites, we hypothesize that this may be plesiomorphic for the Tanaidomorpha. We also report on a peculiar tanaidacean specimen referable to the fossil family Alavatanaidae, Daenerytanais maieuticus gen. et sp. nov., from Early Cenomanian La Buzinie amber (France), preserved with its marsupial pouch and content. Our discoveries provide early evidence of the peracarid reproductive strategy, as seen in modern Tanaidacea, and argue that this form of parental care may have played a role in the diversification of the lineage during this period. The fossil record provides a rich and valuable repository of behavioural and evolutionary developments despite the influence of biases in preservation or density of taxonomic representation.

On the origin and evolution of Antarctic Peracarida (Crustacea, Malacostraca)* ANGELIKA BRANDT Zoological Institute and Zoological Museum, Martin-Luther-King-Platz 3, D-20146 Hamburg, Germany Dedicated to Jürgen Sieg, who silently died in 1996. He inspired this research with his important account of the zoogeography of the Antarctic Tanaidacea. SUMMARY: The early separation of Gondwana and the subsequent isolation of Antarctica caused a long evolutionary his- tory of its fauna. Both, long environmental stability over millions of years and habitat heterogeneity, due to an abundance of sessile suspension feeders on the continental shelf, favoured evolutionary processes of “preadapted“ taxa, like for exam- ple the Peracarida. This taxon performs brood protection and this might be one of the most important reasons why it is very successful (i.e. abundant and diverse) in most terrestrial and aquatic environments, with some species even occupying deserts. The extinction of many decapod crustaceans in the Cenozoic might have allowed the Peracarida to find and use free ecological niches. Therefore the palaeogeographic, palaeoclimatologic, and palaeo-hydrographic changes since the Palaeocene (at least since about 60 Ma ago) and the evolutionary success of some peracarid taxa (e.g. Amphipoda, Isopo- da) led to the evolution of many endemic species in the Antarctic. Based on a phylogenetic analysis of the Antarctic Tanaidacea, Sieg (1988) demonstrated that the tanaid fauna of the Antarctic is mainly represented by phylogenetically younger taxa, and data from other crustacean taxa led Sieg (1988) to conclude that the recent Antarctic crustacean fauna must be comparatively young.

BAMBER ARTOO Marine Biology Consultants, Ocean Quay Marina, Belvidere Road, Southampton SO14 5QY, United Kingdom. E-mail: [email protected] Abstract Apseudomorph tanaidaceans from recent samples of the South China Sea benthos off Brunei have been examined. The habitats were sandy substrata from between 5 and 90 m depth. Fourteen species of the four families considered here were discovered. A new species of Tanapseudes is described. The distribution of Phoxokalliapseudes gobinae is analyzed. Biropalostoma goofi is recorded for the first time in Brunei waters. One new species of the Apseudidae (in the genus Bunakenia) and four new species of the Parapseudidae (one each in the genera Platylicoa and Pakistanapeudes, and two in a new genus Actenos, of the subfamily Pakistanapseudinae) are described. The genus Platylicoa is moved to the Pakistanapseudinae, and the genus Hainanius is returned to the Parapseudidae (Parapseudinae). Apseudes tenuicorporeus is moved from Biropalostoma to the new pakistanapseudin genus described herein.

Yet they have no obligate dispersive phase in their life-cycle. Populations are thus inevitably isolated, and allopatric speciation and high regional diversity are inevitable; cosmopolitan distributions are considered to be unlikely or non-existent.

Chapter 23 Review of the Taxonomy, Diversity, Ecology, and Other Biological Aspects of Order Tanaidacea from Japan and Surrounding Waters Keiichi Kakui Faculty of Science, Hokkaido University, Sapporo, Hokkaido 060-0810, Japan e-mail: [email protected] telephone: +81-11-706-2750 Abstract The order Tanaidacea is a group of benthic crustaceans, most of which are small, up to a few millimeters long. Tanaidaceans are distributed worldwide, with more than 1,200 described species. Following the first taxonomic paper on a Japanese tanaidacean in 1936, many researchers have studied their taxonomy, morphology, reproductive biology, or ecology in the waters around Japan. This chapter presents a brief introduction to tanaidaceans and then reviews what is known of their systematics (taxonomy and phylogeny), biology (including feeding habits, phenology, morphology, reproductive modes, parasites, predators), and ecology in Japan. The chapter ends with a summary and prospects for future research. The general conclusion is that tanaidaceans have been under-studied, both globally and within Japan; the 104 nominal species reported from around Japan and the 1,200 species reported globally likely represent a fraction of the actual diversity. The phylogeny of tanaidaceans is largely unresolved at all taxonomic levels. Recent, significant new discoveries dealing with herbivory, selfing, skin-digging activity in holothuroid hosts, possible sound production, and tube building suggest that much remains to be learned about their general biology.

  • Tube Construction by a Tanaidacean Crustacean Using a Novel Mucus Secretion System Involving the Anal Opening Keiichi Kakui* and Chizue Hiruta
    Kakui and Hiruta Zoological Letters (2017) 3:20 DOI 10.1186/s40851-017-0082-7 RESEARCHARTICLE Open Access Tube construction by a tanaidacean crustacean using a novel mucus secretion system involving the anal opening Keiichi Kakui* and Chizue Hiruta Abstract Background: Animals in diverse aquatic groups construct tubes using mucus and filaments, and the acquisition of this capability has likely played an important role in the evolution and diversification of small benthic animals. Tanaidacea is a crustacean order that includes tube-constructing species, most of which belong to Tanaidoidea and Paratanaoidea, with a few in Kalliapseudidae (Apseudoidea). Two previously reported systems used in tube construction are the thoracic-gland system, with secretory glands in thoracic segments (pereonites), and the pereopodal-gland system, with glands in pereopods. Results: Parapseudidae (Apseudoidea) also includes a tube-constructing species, Parapseudes algicola (Shiino, 1952), which lacks large secretory glands in all pereonites and pereopods, but has a pair of acinar glands in the pleotelson, lateral to the gut. Each gland connects to the gut via a short duct, and thence to the exterior via the anal opening. Secretions released from these glands are used to construct tubes, and contain acidic and neutral mucopolysaccharides. Conclusion: We report in P. algicola a third, novel secretory system, here termed the pleotelsonal-gland system, used for tube construction in Tanaidacea. It is similar to the secretory system in some “thalassinidean” decapods; both systems have secretory glands connecting to the gut and thence to the anal opening as the outlet; however, these gland systems likely evolved independently. Recent discoveries of novel secretory systems for tube construction in Tanaidacea suggest that information from smaller, less well-known groups will be necessary to understand how acquisitions of tube- constructing capability affected diversification in animals.
