Metopa gigas sp. nov. from southern Greenland, a giant among congeners (Crustacea, Amphipoda, Stenothoidae).

Metopa gigas sp. nov. is described from southern Greenland (east and west). This new species which reaches a length of around 20 mm is, together with M. mirifica Gurjanova, 1948 from the North Pacific, by far the largest member of the genus. The species is easily separated from sympatric Metopa clypeata (Kroyer, 1842; 15 mm; type species of Metopa) with which it has been confused, by small saddle-like ornaments dorsally on pereonites, and much longer antenna 1. It can be distinguished from Metopa mirifica by the simple propodus of gnathopod 1, whereas that of M. mirifica is strongly subchelate.

Tirons of the world: a review of tironid amphipods, description of new genera and species, and establishment of a new subfamily Tironinae Stebbing, 1906 stat. nov. (Crustacea, Synopiidae).

The classification of a group of Synopiidae is reviewed based primarily on new material from Australasia and the northern Pacific. A synopiid subfamily, Tironinae Stebbing, 1906 stat. nov. is diagnosed for the following six genera (3 new) consisting of 38 species (18 new): Tiron Lilljeborg, 1865, with 6 species, T. spiniferus Stimpson (type species), T. antarcticus K.H. Barnard, 1932, T. biocellatus J.L. Barnard, 1962, T. canadense sp. nov., T. lilljeborgi sp. nov., and T. sagamiense sp. nov.; Tironella gen. nov. with 3 species, T. altifrons (Reid, 1951, ex Tiron) comb. nov., T. bathyalis sp. nov. (type species), and T. pervicax (J.L. Barnard, 1967, ex Pseudotiron) comb. nov.; Glandulotiron gen. nov. with 15 species, G. pilocaputis sp. nov. (type species), G. salsevisio sp. nov., G. hexamatius sp. nov., G. spinipes sp. nov., G. concavus sp. nov., G. septimus sp. nov., G. meruspinosus sp. nov., G. bassianus sp. nov., G. curvispinus sp. nov., G. aotearoensis sp. nov., G. postremus sp. nov., G. griffithsi sp. nov., G. intermedius (Reid, 1951; ex Tiron) comb. nov., G. quadrioculatus (Dang Le, 2012; ex Tiron) comb. nov., and G. australis (Stebbing, 1908; ex Tiron) comb. nov.; Pseudotiron Chevreux, 1895 with 4 species, P. bouvieri Chevreux, 1895, P. coas J.L. Barnard, 1967, P. golens J.L. Barnard, 1962, P. miratus sp. nov.; Metatiron Rabindranath, 1972, with 4 species, M. brevidactylus (Pillai, 1954, type species), M. bonaerensis Alonso de Pina, 1998, M. triocellatus (Goeke, 1982) and M. tropakis (J.L. Barnard, 1972); and Minitiron gen. nov. with 6 species, M. orpheus sp. nov. (type species), M. bellairsi (Just, 1981; ex. Metatiron) comb. nov., M. caecus (Ledoyer, 1979; ex. Metatiron) comb. nov., M. galeatus (Hirayama, 1988; ex Tiron) comb. nov., M. ovatibasis (Hirayama, 1988; ex Tiron) comb. nov., M. thompsoni (Walker, 1904; ex Tiron) comb. nov. Three species currently in Pseudotiron (P. longicaudatus Pirlot, 1934; P. sublongicaudatus Dang Le, 2012; P. livingstonae Lrz Coleman, 2013) are removed to Synopiidae incertae sedis. Metatiron brevidactylus (Pillay, 1957) by Ledoyer (1979) is removed to Minitiron incerta sedis. Species in the new genus Glandulotiron and a new species of Pseudotiron possess rows of elongate glands in uropods and the telson previously unknown in amphipods. A new key is presented for synopiid genera together with a key to world tironin genera and separate keys for the individual tironin genera. Global distribution and more detailed Australian distribution of the tironins are shown.

Redescriptions and new species in the 'emAustrosignum/em-Munnogonium' complex sensu Just amp; Wilson (2007), mainly from the Southern Hemisphere (Crustacea: Isopoda: Paramunnidae).

Type material is used to illustrate and redescribe the following species in the paramunnid Austrosignum-Munnogonium complex (classification sensu Just and Wilson 2007): Cryosignum incisum (Richardson, 1908), Cryosignum latifrons (Menzies, 1962) comb. nov., Meridiosignum kerguelensis (Vanhöffen, 1914), Munnogonium falklandicum (Nordenstam, 1933), Munnogonium globifrons (Menzies, 1962), and Munnogonium tillerae (Menzies Barnard, 1959,-topotypes).

Review of Sebadexius Ledoyer, 1984 (Amphipoda, Dexaminidae, Dexamininae) based on new material from The Philippines, with Sebadexius cebuense sp. nov.

The amphipod genus Sebadexius Ledoyer, 1984 (New Caledonia) is reviewed, based on new material from Cebu in The Philippines. Some characters are re-interpreted, and a new species, Sebadexius cebuense, is described.

A new species of Cephaloecetes (Bubocorophiina) from the Iranian coasts of the Gulf of Oman and the Hormuz Strait (Crustacea: Amphipoda: Siphonoecetini).

The first member of Cephaloecetes in the north-western part of the Indian Ocean, Cephaloecetes ungulatus sp. nov., is described from Chabahar Bay, the Gulf of Oman and Qeshm Island in the western Hormuz Strait, Iran. The new species is characterized from the other two species of genus Cephaloecetes by a unique claw-shaped ventral plate on antenna 2 article 2.

Siphonoecetini Just, 1983 (Crustacea, Amphipoda, Ischyroceridae) 11: Cephaloecetes schioettei sp. nov. from The Philippines.

The new species described below, Cephaloecetes schioettei, is the second siphonoecetine to be recorded from the archipelago region of Indonesia, The Philippines and Papua New Guinea. The previous reports were of Borneoecetes wongi Barnard & Thomas, 1984 from Borneo and from Papua New Guinea by Myers (1995).

Dendrogramma, new genus, with two new non-bilaterian species from the marine bathyal of southeastern Australia (Animalia, Metazoa incertae sedis)--with similarities to some medusoids from the Precambrian Ediacara.

A new genus, Dendrogramma, with two new species of multicellular, non-bilaterian, mesogleal animals with some bilateral aspects, D. enigmatica and D. discoides, are described from the south-east Australian bathyal (400 and 1000 metres depth). A new family, Dendrogrammatidae, is established for Dendrogramma. These mushroom-shaped organisms cannot be referred to either of the two phyla Ctenophora or Cnidaria at present, because they lack any specialised characters of these taxa. Resolving the phylogenetic position of Dendrogramma depends much on how the basal metazoan lineages (Ctenophora, Porifera, Placozoa, Cnidaria, and Bilateria) are related to each other, a question still under debate. At least Dendrogramma must have branched off before Bilateria and is possibly related to Ctenophora and/or Cnidaria. Dendrogramma, therefore, is referred to Metazoa incertae sedis. The specimens were fixed in neutral formaldehyde and stored in 80% ethanol and are not suitable for molecular analysis. We recommend, therefore, that attempts be made to secure new material for further study. Finally similarities between Dendrogramma and a group of Ediacaran (Vendian) medusoids are discussed.

Atualidade da clínica de orientação psicanalítica em ciências da educação: pesquisas e práticas / Psychoanalytical oriented clinic and educational sciences: research and practices

O presente artigo constitui uma reflexão em torno de um trabalho com grupos de análise de práticas realizados com estudantes de educação especializada, e busca analisar os efeitos psíquicos e sociais desses grupos sobre os estudantes, bem como interrogar sobre o saber que daí pode emergir para cada sujeito. Constatou-se que, nesse trabalho, os es tudantes demonstravam, em inúmeras ocasiões, uma dificuldade de elaborar um saber profissional quanto à sua prática educativa a partir dessas sessões de trabalho. Concluiu-se que tais dificuldades podiam advir de processos relacionados com uma dimensão sadomasoquista da postura dos estudantes

This paper is a reflexion regarding a work with groups that analyze practices which are carried out with Specialized Education students. It tries to analyze the psychic and social effects of these groups over the students, and also to interrogate about the knowledge that can emerge from them. We have noticed that, during this work, the students were not able to elaborate a professional knowledge on their educational practices. We conclude that these difficulties come from processes related to a sadomasochist dimension of the attitude of these students
