Tardigrades of the Australian Antarctic Territories: the Windmill Islands, East Antarctica

Six species of tardigrades, Pseudechiniscus suillus, Macrobiotus sp., Hypsibius antarcticus, Ramajendas frigidus, Diphascon chilenense and Diphascon pingue were extracted from mosses and lichens from the ice-free regions of the Windmill Islands near Casey Base, East Antarctica. Significant positive associations were found between the three common species ( Pseudechiniscus suillus, Hypsibius antarcticus, Diphascon chilenense ) and bryophytes, whereas strong negative associations were found between these species and algae and lichens. There were additional interspecific associations between the common species of tardigrades as well as between tardigrades, nematodes and rotifers.     

Population density and species composition of moss-living tardigrades in a boreo-nemoral forest

This study investigates for the first time the tardigrade fauna in a variety of different mosses from a coniferous forest and an adjacent clear-cut area in southern Sweden. Tardigrades were found in a majority of the samples. Sixteen species were recorded, of which the cosmopolitan species Macrobiotus hufelandi was the far most common. Some mosses, particularly species with "wefts" growth form, contained more tardigrades than other mosses, indicating that growth form may have an impact on tardigrade abundance. Mosses of the same species collected from a forest and from a clear-cut, respectively, did not show a general trend in the overall abundance of tardigrades, but the forest tended to contain more species. Five species of tardigrades ( Murrayon dianae, Isohypsibius sattleri, Platicrista angustata, Diphascon belgicae and Diphascon pingue ) never previously reported from Sweden were recorded.     

Tardigrades of the Taimyr peninsula with descriptions of two new species

This is the first report on tardigrades from the Taimyr peninsula. Seventy-one species of tardigrades were recorded, new to Russian fauna and two of which are new to science. Diphascon boreale sp. nov. is closely related to D. brevipes (Marcus, 1936) but easily distinguished from it by claw structure and the absence of cuticular bars on the legs. Isohypsibius roberti sp. nov. belongs to the elegans group of the genus Isohypsibius ; it diners from other species in the group by having a long and thin buccal tube and large lunulae with small teeth on leg IV. The eggs of Ramazzottius montivagus are here described for the first time. The almost complete absence of tardigrades in and around Norilsk is noted. This is related to the heavy industrial pollution from a local nickel-copper plant.

Tardigrades from Ecuador,with the Description of Two New Species: Mixibius ornatus n. sp. and Diphascon (Adropion) onorei n. sp. (Eutardigrada,Hypsibiidae)

Seven species are reported from Ecuador, South America, two of which, Mixibius ornatus and Diphascon (Adropion) onorei, are new to science. Mixibius ornatus n. sp. differs from Mixibius saracenus (Pilato 1973) and from M. fueginus Pilato & Binda 1997 by having a sculptured cuticle, broader claws, lunulae present, stylet supports inserted on the buccal tube in a more caudal position, and shorter placoids. Diphascon (A.) onorei n. sp. has an elongate pharyngeal bulb with small apophyses, three rod-shaped macroplacoids, a granular microplacoid, and septulum; claw bases enlarged, smooth (first three pairs of legs) or crenate (outer claws on the hind legs); a cuticular bar is present near the inner claws on the first three pairs of legs. Other species reported are Echiniscus aliquantillus Grigarick, Schuster & Nelson 1983; Minibiotus intermedius (Plate 1888); Macrobiotus coronatus De Barros 1942; Macrobiotus danielae Pilato, Binda, Napolitano & Moncada 2001, and Astatumen bartosi Weglarska 1959.     

Tardigrades of South America: Machu Picchu and Ollantaytambo, Peru

During July 1999, a study group from the University of Kansas visited the ancient Inca ruins in and around Machu Picchu and Ollantaytambo, Peru. They collected lichens and mosses from the rock walls around the ruins. The samples contained four genera and six species of tardigrades. No associational patterns and relationships were detected. A new species, Echiniscus ollantaytamboensis nov. sp. is described.     

Eight new species of the genus Micromonospora, Micromonospora citrea sp. nov., Micromonospora echinaurantiaca sp. nov., Micromonospora echinofusca sp. nov. Micromonospora fulviviridis sp. nov., Micromonospora inyonensis sp. nov., Micromonospora peucetia sp. nov., Micromonospora sagamiensis sp. nov., and Micromonospora viridifaciens sp. nov

A previous phylogenetic study on type strains of the genus Micromonospora and Micromonospora species bearing non-validly published names has pointed towards the species status of several of latter strains. Subsequent studies on morphological, cultural, chemotaxonomic, metabolic, and genomic properties, and on whole cell mass spectrometric analyses by matrix adsorbed laser desorption/ionization time-of-flight (MALDI-TOF) confirmed the species status, leading to the proposal of eight new Micromonospora species: Micromonospora citrea sp. nov., type strain DSM 43903T, Micromonospora echinaurantiaca sp. nov., type strain DSM 43904T, Micromonospora echinofusca sp. nov., type strain DSM 43913T, Micromonospora fulviviridis sp. nov., type strain DSM 43906T, Micromonospora inyonensis sp. nov., type strain DSM 46123T, Micromonospora peucetia sp. nov., type strain DSM 43363T, Micromonospora sagamiensis sp. nov., type strain DSM 43912T and Micromonospora viridifaciens sp. nov., type strain DSM 43909T.     

Ascospore diversity of bryophilous Hypocreales and two new hepaticolous Nectria species

Hypocreales represents one of the most successful orders of ascomycetes on mosses and hepatics, and more than 30 obligately bryophilous species belonging to seven genera of Bionectriaceae and Nectriaceae are known. These fungi have a remarkably wide range of ascospore types that differ in form, size and septation. Especially heterogeneous are the ascospores of the six hypocrealean parasites recorded on European populations of Frullania dilatata. Patterns of distribution of bryophilous Hypocreales on this host appear to follow the principles of island biogeography. Two new leaf-perforating species of Nectria with unusual ascospores are described. Nectria foertheri D?bbeler sp. nov. grows biotrophically on Porella sp. in Guatemala, and N. lagodes D?bbeler sp. nov. is a necrotroph on Frullania dilatata in Italy and Greece.

Systematics of the spider genus Metabus O. P.-Cambridge, 1899 (Araneoidea: Tetragnathidae) with additions to the tetragnathid fauna of Chile and comments on the phylogeny of Tetragnathidae

The spider genus Metabus (Tetragnathidae) previously included nine species: the type M. gravidus O. P.-Cambridge, 1899 – junior synonym of Leucauge ocellata (Keyserling) – from Central America and eight species from Chile. In this paper, the classification of the Metabus species-complex is revised, and two new genera, with three new species and five new combinations, are described. Allende gen. nov. is created for four Chilean species not congeneric with the type of Metabus : the type A. puyehuensis sp. nov. , A. patagiatus (Simon) comb. nov. , A. nigrohumeralis (F. O. P.-Cambridge) comb. nov. and A. longipes (Nicolet) comb. nov. Further additions to the Chilean fauna are under the new genus Mollemeta gen. nov. – created for M. edwardsi (Simon) comb. nov. – and three new species of Chrysometa : C. acinosa sp. nov. , C. levii sp. nov. and C. maitae sp. nov. Metabus now includes four species: M. ocellatus (Keyserling) comb. nov. , M. debilis (O. P.-Cambridge) comb. nov. , M. ebanoverde sp. nov. and M. conacyt sp. nov. All of these species were included in a phylogenetic analysis of 38 tetragnathid and 12 orbicularian outgroup terminals scored for 105 morphological and behavioural characters. The results suggest that Metabus as previously circumscribed is polyphyletic. The phylogenetic relationships within tetragnathids are briefly discussed. © 2007 The Linnean Society of London, Zoological Journal of the Linnean Society , 2007, 151 , 285–335.     

Palynology of the Dockum group (Upper Triassic), Texas,U.S.A.

A palynofloral assemblage is described from the Upper Triassic Dockum Group of Texas. Forty palynomorph species are recorded and these are correlated with European Upper Triassic assemblages. The Dockum Group assemblage is considered to be of late Karnian age.Two new genera, Tulesporites gen. nov., type species T. briscoensis sp. nov., and Daughertyspora gen. nov., type species D. chinleanus (Daugherty) comb. nov. have been erected; new species are Converrucosisporites matsenii sp. nov., Pyramidosporites traversei sp. nov., Callialasporites triassicus sp. nov., Plicatipollenites minutotriletus sp. nov., Triadispora dockumensis sp. nov., Bhardwajispora jansonii sp. nov., Protodiploxypinus americus sp. nov., P. ujhelyi sp. nov., Klausipollenites gouldii sp. nov., Pityosporites old-hamensis sp. nov., Abietineaepollenites bujakii sp. nov., Falcisporites oviformis sp. nov. and F. tecovasensis sp. nov.     

STRUCTURE AND REPRODUCTION OF AMANSIA AND MELANAMANSIA GEN. NOV. (RHODOPHYTA,RHODOMELACEAE) ON THE SOUTHEASTERN AFRICAN COAST1

Four species of Amansia Lamouroux were initially found in Natal. More Complete studies on these species revealed a new genus, Melanamansia, Which is described on the basis of presence of two dorsal pseudopericentral cells in two new species from Natal (M. seagriefii sp. nov. & M. fimbrifolia sp. nov.) in addition to other structural characters and features of pigmentation and reproduction. Pseudopericentral cells are not present in the type species of Amansia, A. multifida Lamouroux. The other two species of Amansia occurring in Natal, A. glomerata C. Agardh & A. loriformis sp. nov., have characters similar to the type species. Comparison of species from other regions of the world has shown that eight additional species, previously assigned to Amansia, belong to the new genus.     

Description of four new species in the hard coral genus Acropora Oken, 1815 (Scleractinia: Astrocoeniina: Acroporidae) from south-east Africa

Four new species in the hermatypic scleractinian coral genus Acropora art described from southeast Africa. Two species, A. natalensis sp. nov. and A. mossambica sp. nov. , occur in both South Africa and Mozambique. Two species, A. sordiensis sp. nov. , and A. branchi sp. nov. , are only known from northern Natal in South Africa. A. branchi sp. nov. and A. mossambica sp. nov. are intertidal species and were collected from permanent tidal pools. A. sordiensis sp. nov. and A. natalensis sp. nov. are strictly subtidal species.     

Lecithoceridae (Lepidoptera: Gelechioidea) of New Guinea: Part II. Hamatina gen. nov., with descriptions of four new species

This is the second part in a series of taxonomic studies on the family Lecithoceridae (Lepidoptera: Gelechioidea) of New Guinea. A new genus, Hamatina gen. nov., is described, based on the type species, H. hemitoma (Diakonoff), comb. nov., and four new species are described: H. nabangae sp. nov., H. robdevosi sp. nov., H. jembatana sp. nov., and. iriana sp. nov. A key to four allied genera is given. Adults, heads, labial palpi, wing venations, and the male genitalia are illustrated.     

Marine star-shaped-aggregate-forming bacteria: Agrobacterium atlanticum sp. nov.; Agrobacterium meteori sp. nov.; Agrobacterium ferrugineum sp. nov., nom. rev.; Agrobacterium gelatinovorum sp. nov., nom. rev.; and Agrobacterium stellulatum sp. nov., nom. rev.

Two new species of aerobic, gram-negative, peritrichously flagellated or nonmotile marine bacteria usually forming star-shaped aggregates were isolated from northeastern Atlantic Ocean bottom sediments. These organisms resembled eight star-shaped-aggregate-forming bacterial species from the Baltic Sea originally ascribed to the genus Agrobacterium but not included on the Approved Lists of Bacterial Names because of their questionable relationships to true agrobacteria. These two sets of star-shaped-aggregate-forming bacteria were compared by means of phenotypic data, DNA base compositions, DNA-DNA relatedness, and one-dimensional electrophoretic analysis of low-molecular-weight RNAs (5S rRNA and tRNA). According to the results of genotyping, the northeastern Atlantic Ocean isolates and three of the Baltic Sea species formed a group of closely related bacteria that could not be excluded from the genus Agrobacterium with certainty. Until more genotypic data are available, these five marine species are regarded as a distinct subdivision of the genus Agrobacterium consisting of Agrobacterium atlanticum sp. nov. (type strain, 1480T = DSM 5823T), A. meteori sp. nov. (type strain, 1513T = DSM 5824T), A. ferrugineum sp. nov. nom. rev. emend. (type strain, ATCC 25652T), A. gelatinovorum sp. nov. nom. rev. emend. (type strain, ATCC 25655T), and A. stellulatum sp. nov. nom. rev. emend. (type strain, ATCC 15215T). "A. aggregatum" proved to be a later subjective synonym of A. stellulatum, which had priority. The remaining four Baltic Sea species, "A. agile," "A. kieliense," "A. luteum," and "A. sanguineum," could not be placed in the new subdivision of Agrobacterium.     

Mesozoic leaf beetles of the tribe Mesolpinini trib. nov. (Coleoptera,Chrysomelidae) from the Lower Cretaceous

This publication is based on recent studies of Lower Cretaceous leaf beetles from the Yixian Formation (Liaoning, China), which are represented by five new species of one new genus Mesolpinus gen. nov. (M. antenattus sp. nov. [type species], M. adapertilis sp. nov., M. angusticollis sp. nov., M. basicollis sp. nov., and M. trapezicollis sp. nov.) assigned to a new tribe, Mesolpinini trib. nov. of the subfamily Chrysomelinae. This tribe, which includes only species from the Jehol biota, is the oldest known group of the family in the fossil record. A key to species of the genus Mesolpinus gen. nov. is provided and the position of the new tribe is discussed. A brief overview of the Mesozoic data on the subfamily Chrysomeloidea is given.     

Permian bryophytes of Western Gondwanaland from the Paraná Basin in Brazil

Abstract: This study involves bryophyte fossils from the Teresina Formation (Permian–Guadalupian) collected in the Rio Preto Quarry in the state of Paraná, southern Brazil. Two new genera are proposed, with two new species: Capimirinus riopretensis sp. nov. and Yguajemanus yucapirus sp. nov. C. riopretensis sp. nov. included a lateral sporophyte that was organically attached to a gametophyte and is thus one of the oldest pleurocarpous fossils known today. This discovery provides clear evidence of the evolution of mosses during the Permian, because an acrocarpous moss from this period was also found in India. The preservation of such a fragile structure demonstrates that no prefossilization displacement took place and that the sediments accumulated in a low‐energy, fresh‐water environment, similar to a lake fed by rain, and isolated from the direct influence of the sea. Campimirinus riopretensis may be placed within the earlier pleurocarps, and Yguajemanus yucapirus sp. nov. may belong to the Bryalean families. However, we were not able to place neither of these species in any existing family today.     

VII. A note on the Institute of Seaweed Research

A new genus and two new species are described and compared with related algae. All were isolated from terrestrial habitats on Signy Island, South Orkney Islands, Antarctica. They are Signiosphaera multinucleata gen. et sp. nov. (Tetrasporales, Chlorophyceae), Chlamydocapsa lobata sp. nov. (Tetrasporales, Chlorophyceae) and Chloromonas palmelloides sp. nov. (Volvocales, Chlorophyceae).
