Relationships of eelpouts of the genus <Emphasis Type="Italic">Zoarces</Emphasis> (Zoarcidae,Pisces) inferred from molecular genetic and morphological data

Abstract-Molecular genetic and morphological analysis of eelpouts of the genus Zoarces was carried out. Based on the mitochondrial DNA sequence variation, haplotypes of notched-fin eelpout, Z. elogatus, more closely related Fedorov eelpout, Z. fedorovi, and common eelpout, Z. viviparus, as well as of Andriyashev eelpout, Z. andriashevi, were grouped in one macrocluster. Haplotypes of American eelpout, Z. americanus, and blotched eelpout, Z. gillii, clustered separately from other species. The genetic differences between Z. gillii and the other eelpout species were very high for within-genus comparisons, constituting 7.62%. Species divergence in terms of morphological characters was generally consistent with molecular genetic data and confirmed distinct isolation of American eelpout, and especially of blotched eelpout.     

New species in <Emphasis Type="Italic">Barleria</Emphasis> sect. <Emphasis Type="Italic">Stellatohirta</Emphasis> (<Emphasis Type="Italic">Acanthaceae</Emphasis>) from Africa

Summary  Three new species are described in Barleria L. sect. Stellatohirta M. Balkwill from tropical Africa: B. aristata from south-central Tanzania, B. aenea from south-western Tanzania and northeast Zambia, and B. purpureotincta from south-western Zambia. Their affinities and conservation status are discussed.     

<Emphasis Type="Italic">Shackletonia cryodesertorum</Emphasis> (<Emphasis Type="Italic">Teloschistaceae</Emphasis>, Ascomycota), a new species from the McMurdo Dry Valleys (Antarctica) with notes on the biogeography of the genus <Emphasis Type="Italic">Shackletonia</Emphasis>

A new species of Shackletonia (Teloschistaceae) is described from the McMurdo Dry Valleys in Antarctica, one of the regions with the harshest conditions on Earth. Distinctive traits of the new taxon are the grey thallus, its black lecideine apothecia with a dark greenish blue exterior side of the exciple, Lecidea green pigment present at the cortex and exciple, emodin-dominated anthraquinones only in epithecium, and spores on average 11.2?×?6.0 μm with 3.6 μm wide septum. New chemical data from HPLC analyses further supports the uniqueness of the genus Shackletonia regarding secondary metabolite production within subfamily Xanthorioideae. Using three molecular markers (nrITS, nuLSU, and mtSSU) we found the new species sister to S. sauronii, a species so far known only from Livingston Island (Antarctica). Using secondary calibrations we inferred a long-time evolution of Shackletonia in the Southern Hemisphere, which separated from the remaining lineages of Xanthorioideae between the late Cretaceous and the early Paleogene, and diversified during the late Paleocene and early Oligocene.     

New species of <Emphasis Type="Italic">Chalybea</Emphasis> and <Emphasis Type="Italic">Huilaea</Emphasis> (Melastomataceae)

One new species each is proposed in Chalybea and Huilaea (Melastomataceae: Blakeeae). Chalybea peruviana has elliptic, 5-plinerved leaves with entire, revolute margins, inflorescences with 33–39 flowers, and is endemic to Peru. Huilaea calyptrata has inflorescences with 15–17, irregularly calyptrate flowers, anthers with a warty connective in the shape of an inverted hand fan, and is endemic to Ecuador. A key to the eight species of Huilaea is provided.     

New deepwater species of the genus <Emphasis Type="Italic">Gobiopsis</Emphasis> (Gobiidae) from the Tropical Western Pacific

A new species, Gobiopsis uranophilus sp. n., is described off the Anambas Islands, South China Sea, from a depth of 73 m. The species is similar to the deepwater Japanese species G. namnas, but it differs in the dorsal orientation of the eyes, total absence of pores of the seismosensory system on the head, number of fin rays, and other characters. The similar patterns of the two species (presence of scales on the sides of the head, absence of the barbel-shaped appendages on the head, and large scales on the body), most likely, are connected with their adaptation to deepwater habitats.

New species of <Emphasis Type="Italic">Dypsis</Emphasis> and <Emphasis Type="Italic">Ravenea</Emphasis> (Arecaceae) from Madagascar

Fourteen new species of palms (Arecaceae) from Madagascar are described and named, based on material collected over the last 15 years. Twelve species belong to the genus Dypsis, namely D. andilamenensis Rakotoarin. & J. Dransf., D. anjae Rakotoarin. & J. Dransf., D. betsimisarakae Rakotoarin. & J. Dransf., D. culminis Rakotoarin. & J. Dransf., D. dracaenoides Rakotoarin. & J. Dransf., D. gautieri Rakotoarin. & J. Dransf., D. gronophyllum Rakotoarin. & J. Dransf., D. jeremiei Rakotoarin. & J. Dransf., D. metallica Rakotoarin. & J. Dransf., D. reflexa Rakotoarin. & J. Dransf., D. sancta Rakotoarin. & J. Dransf. and D. vonitrandambo Rakotoarin. & J. Dransf. and two species belong to the genus Ravenea: R. beentjei Rakotoarin. & J. Dransf. and R. hypoleuca Rakotoarin. & J. Dransf. Despite the fact that most of these species have been recorded from protected areas that are difficult to access in the eastern region of Madagasacar, they are all threatened. Based on IUCN categories and criteria, seven are Critically Endangered and seven are Vulnerable.     

<Emphasis Type="Italic">Phuphanochloa,</Emphasis> a new bamboo genus (<Emphasis Type="Italic">Poaceae</Emphasis>: <Emphasis Type="Italic">Bambusoideae</Emphasis>) from Thailand

<Emphasis Type="Italic">Ty</Emphasis>1<Emphasis Type="Italic">/copia</Emphasis>- and <Emphasis Type="Italic">Ty</Emphasis>3<Emphasis Type="Italic">/gypsy</Emphasis>-like DNA sequences in <Emphasis Type="Italic">Helianthus </Emphasis>species

Two repeated DNA sequences isolated from a partial genomic DNA library of Helianthus annuus, p HaS13 and p HaS211, were shown to represent portions of the int gene of a Ty3 /gypsy retroelement and of the RNase-Hgene of a Ty1 /copia retroelement, respectively. Southern blotting patterns obtained by hybridizing the two probes to BglII- or DraI-digested genomic DNA from different Helianthus species showed p HaS13 and p HaS211 were parts of dispersed repeats at least 8 and 7 kb in length, respectively, that were conserved in all species studied. Comparable hybridization patterns were obtained in all species with p HaS13. By contrast, the patterns obtained by hybridizing p HaS211 clearly differentiated annual species from perennials. The frequencies of p HaS13- and p HaS211-related sequences in different species were 4.3x10(4)-1.3x10(5) copies and 9.9x10(2)-8.1x10(3) copies per picogram of DNA, respectively. The frequency of p HaS13-related sequences varied widely within annual species, while no significant difference was observed among perennial species. Conversely, the frequency variation of p HaS211-related sequences was as large within annual species as within perennials. Sequences of both families were found to be dispersed along the length of all chromosomes in all species studied. However, Ty3 /gypsy-like sequences were localized preferentially at the centromeric regions, whereas Ty1/ copia-like sequences were less represented or absent around the centromeres and plentiful at the chromosome ends. These findings suggest that the two sequence families played a role in Helianthusgenome evolution and species divergence, evolved independently in the same genomic backgrounds and in annual or perennial species, and acquired different possible functions in the host genomes.     

A revision of the genus <Emphasis Type="Italic">Podococcus</Emphasis> (<Emphasis Type="Italic">Arecaceae</Emphasis>)

Summary  A taxonomic revision of the palm genus Podococcus (Arecaceae) is presented. Two species are recognised: P. barteri, a species relatively widespread in a coastal band from Nigeria to the D. R. Congo and P. acaulis, a species previously considered conspecific to P. barteri, almost exclusively confined to Gabon. The taxonomic history, morphology, distribution and conservation status of the genus and each species are discussed

New records of <Emphasis Type="Italic">Ardhachandra</Emphasis>, <Emphasis Type="Italic">Dicyma</Emphasis>, and <Emphasis Type="Italic">Sibirina</Emphasis> species from basidiomata of Aphyllophorales (Basidiomycetes) in Japan

Three mitosporic fungi, i.e., Ardhachandra cristaspora, Dicyma pulvinata, and Sibirina gamsii from basidiomata of Aphyllophorales (Basidiomycetes), are described and illustrated. These fungi have not been previously reported in Japan.     

New species in the genus <Emphasis Type="Italic">Francisella</Emphasis> (Gammaproteobacteria; Francisellaceae); <Emphasis Type="Italic">Francisella piscicida</Emphasis> sp. nov. isolated from cod (<Emphasis Type="Italic">Gadus morhua</Emphasis>)

A Francisella strain, GM2212, previously isolated from moribund farmed Atlantic cod (Gadus morhua) in Norway, is closely related to Francisella philomiragia among Francisella spp. according to its complete 16S rDNA, 16S-23S intergenic spacer, 23S rDNA, 23S–5S intergenic spacer, 5S rDNA, FopA, lipoprotein TUL4 (LpnA), malate dehydrogenase and hypothetical lipoprotein (LpnB) sequences. A comparison between GM2212 and the type strain of Francisella philomiragia were performed by DNA–DNA hybridization and fatty acid analysis. The DNA–DNA hybridization showed a 70% similarity. The fatty acid analysis showed only minor differences between the Francisella isolates. Due to the inconclusive result from the DNA–DNA hybridisation, major emphasis concerning the status of this isolate is made on previously published molecular, phenotypic and biochemical characters. All characteristics taken together support the establishment of GM2212 as a novel species, for which the name Francisella piscicida sp. nov. is proposed (=CNCM I-3511^T = DSM 18777^T = LMG registration number not yet available).     

New species of the genus <Emphasis Type="Italic">Scolecostigmina</Emphasis> and revision of <Emphasis Type="Italic">Cercospora cryptomeriicola</Emphasis> on conifers

Systematic review of the genus <Emphasis Type="Italic">Bothrocara</Emphasis> Bean 1890 (Teleostei: Zoarcidae)

The systematics of the eelpout genus Bothrocara Bean 1890 is reviewed on the basis of 941 specimens. Eight mostly eurybathic, demersal species are recognized, distributed mainly along the continental slopes of the North and South Pacific oceans, with one species entering the South Atlantic. Distributions are: B. brunneum ranges from the Sea of Okhotsk to the Gulf of Panama at depths of 199–1,829 m; B. elongatum ranges from the Gulf of Panama to Chile at depths of 720–1,866 m; B. hollandi ranges from the Sea of Japan to the southeastern Bering Sea at depths of 150–1,980 m; B. molle ranges from the western Bering Sea to the South Atlantic at depths of 106–2,688 m; B. nyx is known only from the eastern Bering Sea at depths of 790–1,508 m; B. pusillum ranges from the northern Bering Sea to British Columbia, Canada, at depths of 55–642 m; B. tanakae is found along the northern coasts of Honshu and Hokkaido islands, Japan, at depths of 274–892 m; B. zestum ranges from the Izu Islands, Japan, and central Honshu, Japan, to the Gulf of Alaska at depths of 199–1,620 m (an unidentifiable specimen from off Taiwan may be B. zestum). The species are distinguished from one another mainly on the basis of head pore patterns, gill raker morphology, coloration and various meristic and morphometric values. A determination key to the species is provided.
