The infraorder Thalassinidea Latreille, 1831 [sensu stricto] includes three families: Thalassinidae Latreille, 1831; Upogebiidae Borradaile, 1903; and Laomediidae De Haan, 1849 (cf. Sakai & Sawada, 2006). However, recent examination of material from Kuwait in the Pershian Gulf, showed the occurence of a new species,Kuwaitupogebia nithyanandangen. et sp. nov., and this has made it possible to establish a new family, Kuwaitupogebiidae fam. nov., based on that new genus. The genusUpogebiaLeach, 1814 is known to include nine species from the Red Sea area, yet herein two new species,Upogebiaspongicolasp. nov. from the Reef at Hurghada, Red Sea, Egypt, andUpogebia jizanensissp. nov. from off Jizan, Saudi Arabia, Red Sea, can be added, based on material lodged in the collections of the museum in Frankfurt a. M.

The Tanaidacea are ubiquitous and amongst the most abundant taxa in the deep sea. However, their diversity in submarine canyons remains largely unknown. Here, two new species and a new genus of Paratanaoidea are described. Paranarthrura cousteaui sp. nov. is distinguished by the combination of the following characters: post-cheliped sclerites not fused, presence of one seta in the maxilliped endite, one long midventral seta in cheliped, one penicillate seta in the basis of pereopods 4–6, uropod endopod bi-articulated and uropod exopod shorter than endopod article 1. This species was found at the upper reaches of three Portuguese canyons, Cascais, Setúbal and Nazaré Canyons, and the adjacent open slope, between 897 and 1001 m water depths. Tirana vallis gen. et sp. nov. presents a combination of the characters that define the other two genera of Paranarthrurellidae, Paranarthrurella and Armatognathia, but also unique characters within the family: the antenna, cheliped and uropod are more elongate than the rest of the species; the pereopods 4–6 carpus spines reach at least half of the length of the propodus and the propodus of pereopods 4–6 have ramified subdistal spines. This species was found at the middle reaches of Setúbal Canyon (3214–3219 m water depth).

Abstract The phylogenetic study of the deep-sea genus Bentheogennema is based on four molecular markers and 79 morphological characters. All four previously recognized species and two new species of Bentheogennema, representatives of all other genera and species groups of Benthesicymidae, and three outgroups were included in the analyses. We have examined and coded six major groups of morphological characters related to the carapace (three characters), the pleon and the telson (14), the mouthparts (nine), the armature of the pereopods (five), the thelycum (27) and the petasma (21). Results of morphological and molecular analyses were similar. Two species were transferred from Bentheogennema to other genera (for one of them a new genus was erected) and two new species of Bentheogennema were described. Three pelagic genera (Gennadas, Bentheogennema and a new genus) created a robust clade. The divergence of this clade is linked to ‘smoothening’ of the body (reduction of the branchiostegal spine on the carapace, reduction and loss of the dorsolateral spines and the end-piece on the telson) and elaboration of the copulatory structures. We provide amended diagnoses of these three pelagic genera and key to species of Bentheogennema.

Two new species of alvinocaridid shrimps are described from a hydrothermal vent field off northeastern Taiwan at depths of 252–300 m. Alvinocaris chelys n. sp. is morphologically very similar to A. williamsi Shank & Martin, 2003 from the Mid-Atlantic Ridge, and A. alexander Ahyong, 2009 from the southern Kermadec Ridge. These three species can be differentiated by the shape of the postrostral ridge, telson, the second segment of the antennular peduncle and the armature of the meri and ischia of the third pereopod. The second new species, although rather similar to Alvinocaris niwa Webber, 2004 from the Kermadec-Arc, is assigned to a new genus Alvinocaridinides gen. nov., which appears to be intermediate between Shinkaicaris Komai & Segonzac, 2005 and other derived genera including Opaepele Williams & Dobbs, 1995, Chorocaris Martin & Hessler, 1990 and Rimicaris Williams & Rona, 1986. Alvinocaridinides formosa n. sp. differs from Alvinocaris niwa by completely lacking any armature on the ischia of the third to fifth pereopods and by bearing two movable spines at the posterolateral angle of the uropodal exopod. These records constitute the first discovery of the family Alvinocarididae in Taiwanese waters and represent the shallowest occurrence for alvinocaridid shrimps.

ABSTRACT Fedorowski, J. and Kullmann, J. 2013. Vojnovskytesidae - a new family of Mississippian Rugosa (Anthozoa). Acta Geologica Polonica, 63(4), 657-679. Warszawa. Two new species of the genus Vojnovskytes Fedorowski, 2009, namely V. marcinowskii and V. arcuatus, and a new genus, Vojnimitor, based on the new species V. proiectus, all from Mississippian strata of northern Spain, are described. Vojnovskytes variabilis (Vojnovsky-Krieger, 1934), the type species for the genus from the lowermost Visean strata of southern Urals, also is discussed and illustrated. Characters displayed by the taxa mentioned permit introduction of a new family Vojnovskytesidae.

Spherical Structures

The genus Kathistes is described to accomodate two new species, K. calyculata and K. analemmoides, and an existing one based on Pyxidiophora fimbriata Barrasa & Moreno. All three species are coprophilous and produce transversely septate ascospores in long-necked perithecia. Ascospore germination occurs by the production of budding yeast cells. Sporelike bodies, termed sporidiolae, are produced in spherical structures resembling the perithecia called sporidiomata. Similar genera and species are discussed and contrasted by a dichotomous key. Kathistes species do not appear to be closely related to other ascomycetes and are assigned to a new family Kathistaceae.

Alvinella Pompejana

Examination of all the specimens collected from deep hydrothermal vents in the eastern Pacific allowed us to describe two new species and one new subspecies belonging to the genus Paralvinella Desbruyères and Laubier, 1982: P. pandorae sp.n., P. palmiformis sp. n., and P. pandorae irlandei ssp. n. Alvinella pompejana is split into two species, A. pompejana and A. caudata sp.n., based on to morphological and biochemical data. The six species and subspecies of Alvinellinae (Polychaeta: Ampharetidae) are well separated from all other terebellomorph species by the absence of differentiation between thorax and abdomen. We propose here the erection of a new family, Alvinellidae, which seems to be primitive within the order Terebellida. All known alvinellids are strictly associated with deep hydrothermal vent phenomena.

New Diagnosis

A new genus of Eurycopinae (Munnopsidae), Dubinectes gen. nov., is described for Eurycope acutitelson Menzies, 1962, E. nodosa Menzies, 1962 and two new species, collected from the Weddell Sea, Southern Ocean. The new genus is distinguished by the distinctive shape of the pleotelson posterior margin and the uropod protopod angled at midlength, along with the robust, long rostrum of a large head, overhanging frons, reduced distomedial lobe of article 1 of antenna 1, the produced male pleopod 1 distolateral lobes and the distinct shape of the male pleopod 2. Descriptions of the new genus, two new species and redescriptions of two previously described species are presented, as well as a new diagnosis of the subfamily Eurycopinae, the genus Eurycope and a key to the genera of Eurycopinae.
