CharcotianaandAmundsenia, two new genera inTeloschistaceae(lichenized Ascomycota, subfamilyXanthorioideae) hosting two new species from continental Antarctica, andAustroplaca frigida, a new name for a continental Antarctic species

AbstractBased on a combined three locus analysis two new genera,CharcotianaandAmundsenia,are proposed in the lichen familyTeloschistaceae, subfamilyXanthorioideae.Charcotianaincludes the new speciesC. antarctica, which is known only from continental Antarctica. The bipolar genusAmundseniaincludes the new speciesA. austrocontinentalis, which is also known only from continental Antarctica, and the Arctic speciesCaloplaca approximatawhich is here combined into the new genus. The two new genera are phylogenetically distinct, but poor in morphological characters; the new species consist mainly of minute apothecia in cracks of rocks located in the climatically harshest regions of the Antarctic. They are somewhat similar to another continental Antarctic species,Austroplaca frigida,which is described as a new name based on the illegitimate nameCaloplaca frigidaSøchting. The distribution of the four species is mapped.

AbstractSystematic analysis shows that the Southern Hemisphere bivalve genus Retrotapes includes the Antarctic species R. antarcticus, R. newtoni, and R. robustus and recognizes for the first time the presence of Katelysia represented by K. florentinoi. Two new genera were erected in this study: Marciachlys new genus to include M. inflata new combination, and Adelfia new genus, which includes A. austrolissa new combination and A. omega new species from the Eocene of Antarctica, and the late Eocene Chilean A. arenosa new combination. Eurhomalea carlosi was synonymized with K. florentinoi; Cyclorismina marwicki with R. antarcticus; Gomphina iheringi was considered an indeterminate species; and Cockburnia lunulifera was excluded from the Tapetinae. These systematic assignments are supported by a phylogenetic analysis, which recognizes an Austral clade of Tapetinae, comprising all the genera mentioned above, along with Marcia, Paleomarcia, Atamarcia, and Protapes.UUID: http://zoobank.org/a8c91a9f-99ec-4235-8416-d398771a3eb2

New Name

Three cleistothecial marine Ascomycotina collected on driftwood along the Danish coasts are compared. The three species are described as new and each accommodated in its own new genus: Biflua physasca, Marisolaris ansata, and Dryosphaera navigans. Dryosphaera navigans is a new name for what earlier was understood as Crinigera maritima Schmidt, a cleistothecial fungus with treelike appendages covering the surface of the peridium and ascospores with slime threads spirally uncoiling from the spore wall. All three species have cleistothecia with sterile appendages, occur on driftwood associated with sand, are loosely attached to the substratum at maturity, and have appendaged ascospores. The morphological characters of the three species are compared and all are considered to have affinities to the bitunicate ascomycetes. Tentatively D. navigans is assigned to the Coronophorales, but no order or family was found to accommodate the remaining new species. An amended diagnosis is provided for Crinigera maritima Schmidt, and it is concluded that material does not show whether the fungus is an ascomycete or a fungus imperfectus.

Morphological Differences

During field studies of the inselbergs of northeastern Brazil, two potentially new species of were discovered. They share morphological characters with several genera of Linderniaceae (Lamiales) such as Ameroglossum, Cubitanthus and Stemodiopsis, but the morphological differences are such that they do not make a good fit with any of the known genera in Linderniaceae. They are most likely related to Ameroglossum, and like most members of this genus the plants have a conserved chromosome number of 2n = 60. Their exclusive occurrence on inselbergs in northeastern Brazil also hint at this relationship, but because their morphology differs greatly from Ameroglossum and each other, the two new species are described in separate genera. Catimbaua is a pendent plant somewhat similar to Cubitanthus, but with different stem morphology and indumentum. Isabelcristinia grows in habitats similar to, but drier than, Ameroglossum and is vegetatively similar. However, it is covered in glandular hairs and has open-throated white flowers rather than the red or orange tubular flowers found in Ameroglossum. Catimbaua pendula and Isabelcristinia aromatica are rare, and both are likely to fall in a category of threat.

Gene Data

We describe two new species of spherical single-chambered ('saccamminid') foraminifera from the bathyal and abyssal Weddell Sea (Southern Ocean), collected in epibenthic sledge and Agassiz trawl samples obtained during the 2005 ANDEEP III campaign. Both are assigned to Leptammina gen. nov. The new genus is similar in overall test morphology to Saccammina Carpenter, 1869; it is distinguished mainly by its test wall, which is delicate, flexible and composed of fine mineral grains, rather than being rigid and coarsely agglutinated. In Leptammina grisea gen. et sp. nov., the test wall is relatively thick, grayish with a violet tinge and a dull surface; the cytoplasm is dark greenish. In Leptammina flavofusca gen. et sp. nov., the test is yellowish brown, with a very finely, almost transluscent agglutinated wall; the cytoplasm is pale yellowish. Both species have prominent circular apertures. Maximum likelihood phylogenetic analysis of SSU rRNA gene data showed that both species group together with an undescribed shallow-water Antarctic species (“silver saccamminid”) in a very strongly supported clade (100 %). Leptammina grisea gen. et sp. nov. is a relatively uncommon species (29 specimens from 3 stations), found at 1580–4822 m depth in the central and north–western Weddell Sea; Leptammina flavofusca gen. et sp. nov. is common (398 specimens from 4 stations) at depths of 3138–4795 m in the central Weddell Sea and off Kapp Norvegia. Both species are presently known only from ANDEEP III samples.

Pygmy grasshoppers (Tetrigidae) are a speciose group of complicated taxonomy, with many species requiring clarification on their species boundaries, and more still awaiting discovery. Two new species of Scelimena Serville, 1838 are described: (1) from S. discalis species group S. gombakensis sp. nov. and (2) from S. hexodon species group Scelimena marta sp. nov. Catalogue of Scelimenini genera (15) and species (100) is presented and taxonomy and biogeography of the tribe are discussed. New and resurrected combinations are: Falconius becvari (Buzzetti & Devriese, 2008) comb. nov. (of Gavialidium becvari), Gavialidium carli Hebard, 1930 comb. resurr. (of Bidentatettix carli), Indoscelimena india (Hancock, 1907) comb. nov. (of Scelimena india), Paragavialidium nodiferum (Walker, 1871) comb. nov.

Mite Family

Unlike most terrestrial parasitengone mites (chiggers, erythraeids), known mostly from parasitic and easy-to-collect larvae, smaridid systematics are mainly based on the post larval instar. Larvae are rarely collected, and their biology and host associations are virtually unknown. Here we infer phylogenetic relationships of Smarididae based on 50 morphological characters using both larval and post larval instars, including data on the larval morphology of Trichosmaris obtained through rearing. The subfamily Smaridinae, as currently understood, was recovered paraphyletic: the genus Smaris was rendered as basal smaridid lineage, while the genus Fessonia (Smaridinae) was sister to Hirstiosomatinae, albeit with moderate support. Our analysis suggests that the genus Surasmaris Southcott, 1995 is a junior synonym of Trichosmaris Southcott, 1963 (syn. nov.), and two Sphaerotarsus species should be placed into Hirstiosoma: Hirstiosoma baenai (Mayoral & Barranco, 2017) comb. nov., Hirstiosoma quercus (Yazdanpanah, Saboori & Hakimitabar, 2016) comb. nov. Sphaerotarsus monticolus Southcott, 1997 and S. leptopilus were recovered as independent lineages, and hence, a new genus Southcottiana gen. nov. is proposed to include Southcottiana monticola comb. nov (Southcott, 1997). We describe two new species, Trichosmaris paulensis sp. nov. (adults, larvae) and T. calcarensis sp. nov. (larva), and present the first description of larval T. dispar, the type species of Trichosmaris, previously known only from post larval instars. Based on the above results, we give a key to larval genera of Smarididae and a key to species of Trichosmaris (larval and postlarval instars).

Paramunnid species of Southern Hemisphere cold-water Austronanus Hodgson, 1910 and related genera are characterised by simple, smooth, flattened, rather elongate oval bodies, a broadly projecting frontal head margin, well-developed, short, mostly distally bulging eyestalks with ommatidia, pereonites with lateral margins contiguous, rounded or truncate, and dorsally visible coxae V–VII. Just and Wilson (2004) rejected synonymy of Austronanus with Paramunna Sars proposed by Nordenstam (1933), following a revision of the latter genus. The type species, Austronanus glacialis Hodgson, 1910, is re-described based on topotypic material from McMurdo Sound, Antarctica, (the holotype is a small manca). The types of Paramunna dentata Nordenstam, 1933 and P. dubia Hale, 1937 are re-described and the two species referred to Austronanus together with three new Antarctic and subantarctic species, A. aucklandensis, A. gelidus and A. mawsoni. Paramunna patagoniensis Winkler, 1994 is redescribed and made the type species of a new genus, Xigonus. A new genus, Stephenseniellus, is established for two new species from the subantarctic islands south of New Zealand and Australia, S. palliolatipes (type species) from Macquarie Island, and S. serraticornis (originally reported by Stephensen, 1927 as “Paramunna (serrata (Richardson) ?”) from Auckland Island.
