Four new species of Desmosomatidae Sars, 1897 (Crustacea: Isopoda) from the deep sea of the Angola Basin

From a total of 104 species and 1741 individuals of Isopoda, the material from DIVA-1 (DIVersity of the Atlantic benthos) contained 364 specimens belonging to Desmosomatidae Sars, 1897. They are represented by 10 genera and 27 species. Most species (93%) are new to science. Four species are described in this study (Eugerdella theodori sp. nov., Desmosoma renatae sp. nov., Torwolia tinbiene sp. nov. and Momedossa longipedis sp. nov.). A discussion of the genera Desmosoma Sars, 1864, Momedossa Hessler, 1970 and Torwolia Hessler, 1970 is presented.     

Glass sponges (Porifera, Hexactinellida) of the northern Mid-Atlantic Ridge

Glass sponges (Hexactinellida) collected under the framework of the MAR-ECO project on the G.O. Sars cruise to the northern Mid-Atlantic Ridge, between the Azores and the Reykjanes Ridge, and on the 49th cruise of Akademik Mstislav Keldysh to the Charlie-Gibbs Fracture Zone are described. Fourteen species were identified in the material. This relatively rich fauna includes several novel findings, indicating that the hexactinellid fauna of the northern Mid-Atlantic Ridge is poorly investigated. One genus, Dictyaulus, has never before been reported from the Atlantic Ocean. Two species belonging to the genera Heterotella and Amphidiscella are new to science. Two other species, Rossella nodastrella Topsent, 1915 and Doconestes sessilis Topsent, 1928, have been collected just one other time. Finally, a probable new genus of Euplectellidae, which unfortunately cannot be adequately described because of how small the specimens are, is represented among these collections. A large portion of dead, rigid skeletons of Euretidae and spicule mats of Rossellidae are also reported but not described in detail. Representation of some genera in the Charlie-Gibbs Fracture Zone, coupled with recent observations from elsewhere along the Mid-Atlantic mountain chain, suggests that this fauna is as similar to those of the Indian Ocean and Indo-West Pacific as it is to West or East Atlantic faunas.     

Description of two new species of Bodinia, a new genus incertae sedis in Argestidae Por, 1986 (Copepoda, Harpacticoida), with reflections on argestid colonization of the Great Meteor Seamount plateau

The present paper focuses on the results of taxonomic, faunistic and chorologic investigations on Argestidae Por, 1986 (Copepoda, Harpacticoida). All argestid species collected during the cruise M42/3 of RV “Meteor” (1998) are new to science. In the present contribution, two species are described and united within Bodinia gen. nov.: Bodinia meteorensis sp. nov. and Bodinia peterrummi sp. nov. The new genus is placed as incertae sedis in Argestidae in light of uncertainty concerning the phylogenetic relations within this group and even its status as a monophylum. The question is discussed how members of Argestidae, previously seen as a deep-sea taxon, may have colonized the shallow-water habitat of the Great Meteor Seamount plateau.

Ants of the tribe Formicini (Hymenoptera,Formicidae) from Late Eocene amber of Europe

The tribe Formicini (Formicinae) from the Late Eocene Baltic, Bitterfeld, Rovno, and Scandinavian ambers is revised. Ants are recorded for the first time from the Bitterfeld and Scandinavian ambers. Two new genera (Cataglyphoides gen. nov. and Conoformica gen. nov.) and six new species (Cataglyphoides intermedius sp. nov., Conoformica bitterfeldiana sp. nov., Formica kutscheri sp. nov., F. palaeopolonica sp. nov., F. radchenkoi sp. nov., F. zherikhini sp. nov.) are described. A new combination, Cataglyphoides constrictus (Mayr, 1868), comb. nov., is established. A lectotype of Camponotus constrictus Mayr, 1868 and a neotype of Formica phaethusa Wheeler, 1915 are designated. Formica clymene Wheeler, 1915 is recognized as a new synonym of F. phaethusa Wheeler, 1915. An identification key for workers of Formicini species from Late Eocene European ambers is provided.     

Four new species of Orbiliaceae from Yunnan, China

During the fungal survey in YongPing County, Dali area in southwest China, a total of 50 specimens of Orbiliaceae were collected. Among them, were four apparently uncommon taxa growing on bark and wood of decayed branches of undetermined broad-leaved trees lying on the moist ground. They are described here as new species: Orbilia acicularis sp. nov., O. arcospora sp. nov., O. limoniformis sp. nov., and Hyalorbilia nodulosa sp. nov. Orbilia acicularis is characterized by needle-shaped straight ascospores, O. arcospora by spores being curved like an arch, O. limoniformis according to its lemon-shaped spores, and Hyalorbilia nodulosa by the knob-like glassy processes on the marginal excipular cells, the three Orbilia species also by filiform to subulate spore bodies (SBs) in the living spores.     

Late Cretaceous Arman Flora of the Magadan District: Composition, age, and new plant species

The Arman Flora comes from volcanic-sedimentary deposits of the Arman Formation in the Arman River basin and from volcanic and volcanic-sedimentary rocks of the Nel??kandzha-Khasyn Interfluve. It comprises about 80 fossil plant species. The Arman Flora is dated as Turonian and Coniacian because of its similarity to the reliably dated Penzhina and Kaivayam floras of the northwestern Kamchatka Peninsula and Tylpegyrgynai Flora of the Pekul??nei Ridge. This is corroborated by isotopic (U-Pb and ⁴⁰Ar/³⁹Ar) age determination for the plant-bearing layers. New conifer and angiosperm species of the Arman Flora are described: Pagiophyllum parvum sp. nov., Araliaephyllum armanensis sp. nov., Terechovia philippovae sp. nov., and Parvileguminophyllum samylinae sp. nov.

Previously undocumented diversity and abundance of cryptic species: a phylogenetic analysis of Indo-Pacific Arminidae Rafinesque, 1814 (Mollusca: Nudibranchia) with descriptions of 20 new species of Dermatobranchus

The phylogenetic relationships amongst the Arminidae were analysed based upon morphological characters of 58 presently described species or nudibranchs, including 35 previously described Arminidae and 20 new species of Dermatobranchus. From the literature review and anatomical examinations, 43 characters were considered for 78 taxa. These characters were polarized using Berthella canariensis as the outgroup taxon and the type species of several other genera identified from recent publications. The resulting phylogeny supports the monophyly of Arminidae, Dermatobranchus, Doridina, and Proctonotidae. The paraphyly of the Arminina is further demonstrated in this study. Two previously described, but poorly known, species of Indo-Pacific Armina are redescribed, Armina magnaBaba, 1955 and Armina paucifoliataBaba, 1955. The anatomy and taxonomic status of nine previously described species of Dermatobranchus were examined in this study. The anatomy of Dermatobranchus pustulosus (van Hasselt, 1824) has been overlooked since Bergh (1888) illustrated the radula of van Hasselt's specimen. It is redescribed and its range is extended to several new localities in the western Pacific. Dermatobranchus pulcherrimus Miller & Willan, 1986 is considered here as a new synonym of Dermatobranchus rubidus (Gould, 1852). The following 20 species of Dermatobranchus are new and are described in the present paper: Dermatobranchus albineus sp. nov., Dermatobranchus arminus sp. nov., Dermatobranchus caesitius sp. nov., Dermatobranchus caeruleomaculatus sp. nov., Dermatobranchus cymatilis sp. nov., Dermatobranchus dendonephthyphagus sp. nov., Dermatobranchus diagonalis sp. nov., Dermatobranchus earlei sp. nov., Dermatobranchus fasciatus sp. nov., Dermatobranchus funiculus sp. nov., Dermatobranchus kalyptos sp. nov., Dermatobranchus kokonas sp. nov., Dermatobranchus leoni sp. nov., Dermatobranchus microphallus sp. nov., Dermatobranchus oculus sp. nov., Dermatobranchus phyllodes sp. nov., Dermatobranchus piperoides sp. nov., Dermatobranchus rodmani sp. nov., Dermatobranchus semilunus sp. nov., and Dermatobranchus tuberculatus sp. nov. Eighteen of these new taxa are found in the Indo-Pacific tropics and two are found in temperate South Africa, D. albineus and D. arminus. Unique combinations of morphological characters distinguish these as new species of Dermatobranchus. Several species that are externally similar have radically divergent internal morphology, are members of different clades of Dermatobranchus, and represent cryptic species. Especially important is the radular morphology, which shows remarkable diversity of form, probably related directly to the diversification of feeding of members of this clade on various octocorals.
