Revised typification of the Linnaean name Lobelia zeylanica (Campanulaceae)

A previously designated lectotype for the name Lobelia zeylanica is here superseded since the priority of type choice was violated, and a new lectotype is designated using a specimen collected by Osbeck and kept at the Swedish Museum of Natural History (S).

The Swedish marine nematologist Carl Allgén (1886-1960): a bio-bibliography and his collection.

The Swedish marine nematologist Carl Allgén (1886-1960) published 185 scientific papers on parasitic, terrestrial, limnic and especially marine nematodes between 1921 and 1960. Among them are also some papers on species of suctorians found mostly on desmodorid nematodes. He described about 70 new genera and over 800 new species and subspecies of nematodes. Allgén left a large collection of nematodes to the Swedish Museum of Natural History in Stockholm and it is now deposited in the invertebrate collection of the Zoology department. The collection comprises about 4500 slides in total, with about 310 slides containing type specimens collected from the Arctic to Antarctica. Allgén's publications have to a large extent been ignored by scientists working on marine nematodes, likely because of the poor quality of many of his species descriptions. The authors want to remind the scientific community about the existence of Allgén's collection, its availability for study and its importance for nematode taxonomy and systematics. A complete list of Allgén's publications, a list of all species described by him, and a list of type material available is presented.

Redescriptions of Scirtidae (Coleoptera: Scirtoidea) described by Carl Henrik Boheman (1796-1868) with notes on Scirtes adustus iversenotatus Pic, 1930.

Boheman described four species of Scirtidae: one from Sweden (Cyphon pallidulus Boheman, 1850), two from South Africa (Elodes caffer Boheman, 1851 & Elodes marginipennis Boheman, 1851), and one from Argentina (Scirtes adustus Boheman, 1858). Cyphon pallidulus Boheman is a junior synonym of Contacyphon ochraceus (Stephens, 1830). Types of the remaining species were never re-examined, and none of them were redescribed. In the present paper, three species are redescribed on the basis of type specimens deposited in the Swedish Natural History Museum in Stockholm. Genitalia are illustrated for the first time and a new combination is proposed: Brachycyphon marginipennis (Boheman, 1851). The type specimen of a variety described by Pic, S. adustus var. diversenotatus, was examined and revealed to represent a distinct species, which is redescribed under the name of Scirtes diversenotatus Pic, 1930 stat. nov. in the present paper.

Siluro-Devonian trace fossils from the Mereenie Sandstone, Kings Canyon, Watarrka National Park, Amadeus Basin, Northern Territory, Australia

Gouramanis, C. & McLoughlin, S., January 2016. Siluro-Devonian trace fossils from the Mereenie Sandstone, Kings Canyon, Watarrka National Park, Amadeus Basin, Northern Territory, Australia. Alcheringa 40, xxx–xxx. ISSN 0311-5518Nine trackways referable to the ichnogenus Diplichnites are preserved in the upper Silurian to Lower Devonian Mereenie Sandstone at Kings Canyon, Watarrka National Park, Northern Territory, Australia. Eight trackways are consistent with earlier descriptions of D. gouldi, and one trackway could not be assigned to an ichnospecies. The trackways are co-preserved with a range of sub-horizontal burrows referable to Beaconites and Taenidium, and several vertical burrows, surficial circular traces and a horizontal trail of uncertain identities. The ichnofossil assemblage highlights the diversity of animals present in the late Silurian to Lower Devonian paralic to fluvial environments of central Australia at the time of early colonization of the land’s surface. The assemblage is similar to ichnofaunas from coeval strata elsewhere in Australia and throughout Gondwana, and it highlights the potential of this region for further ichnological studies to elucidate the early stages of terrestrialization in the palaeoequatorial belt.Chris Gouramanis [cgouramanis@ntu.edu.sg], Earth Observatory of Singapore, Nanyang Technological University, Singapore, 639798; Stephen McLoughlin [steve.mcloughlin@nrm.se], Department of Palaeobiology, Swedish Museum of Natural History, Box 50007, S-104 05 Stockholm, Sweden.

Late Cretaceous (Campanian) leaf and palynoflora from southern Skåne, Sweden

Abstract A Late Cretaceous (Campanian) leaf megaflora from the Vomb Trough in southern Skåne, Sweden, has been investigated on the basis of collections held at the Swedish Museum of Natural History. The main plant-bearing locality is Köpinge, but single specimens originate from Högestad, Ingelstorp, Rödmölla, Svenstorps mölla and Tosterup. The fossil flora is dominated by the angiosperm (eudicot) Debeya ( Dewalquea ) haldemiana (Debey ex de Saporta & Marion) Halamski. Other dicots are cf. Dryophyllum sp., Ettingshausenia sp., Rarytkinia ? sp., Dicotylophyllum friesii (Nilsson) comb. nov. and Salicites wahlbergii (Nilsson) Hisinger. Conifers are represented by cf. Aachenia sp. (cone scales), Pagiophyllum sp. and Cyparissidium sp. (leaves). Single poorly preserved specimens of ferns and monocots have also been identified. The terrestrial palynomorphs (the focus herein) clearly link to the megaflora, although with different relative abundances. The fern spore Cyathidites dominates along with the conifer pollen Perinopollenites elatoides and Classopollis . Angiosperm pollen comprise up to 15% of the assemblage, represented by monocolpate, tricolpate and periporate pollen and the extinct Normapolles group. The spores in the kerogen residue show a thermal alteration index (TAI) of 2+. The flora probably represents mainly a coastal lowland Debeya /conifer forest, and is similar to approximately coeval assemblages from analogous palaeo-communities described from eastern Poland, western Ukraine and Westphalia.

A review of the Palaearctic species of Larinus Dejean (Coleoptera: Curculionidae) in C. J. Schoenherr collection: nomenclature and lectotype designations

The syntypes of 41 species of Larinus Dejean described by L. Gyllenhal and C. H. Boheman, housed at the C. J. Schoenherr collection in the Swedish Museum of Natural History, Stockholm and the Museum of Evolution, Uppsala University, are examined. Lectotypes are designated, a nomenclatural review performed, many previous synonyms confirmed and three new synonyms proposed: Larinus planus (Fabricius, 1792) (= Larinus rusticanus Gyllenhal, 1835 syn. nov.); Larinus carlinae (Olivier, 1807) (= Larinus sulphurifer Boheman, 1843 syn. nov.); Larinus minutus Gyllenhal, 1835 (= Larinus puncticollis Capiomont, 1874 syn. nov.). Colour images for 15 lectotypes are presented.

Paws for thought on dog-wolf split

An analysis of a bone from a newly identified ancient wolf species suggests that dogs may have split from wolves as early as 40,000 years ago. Now Love Dalen from the Swedish Museum of Natural History in Stockholm and his colleagues have sequenced the genome of a wolf that lived 35,000 years ago in Taimyr, Siberia. This allowed them to recalibrate the rate at which genetic differences have accumulated over time and better reconstruct the evolutionary tree. They found that dogs and wolves must have split into different lineages between 27,000 and 40,000 years ago, bringing the DNA and archaeological evidence into line.

An annotated catalogue of the types of Chrysididae (Hymenoptera) at the Swedish Museum of Natural History, Stockholm, with brief historical notes

A critical and annotated catalogue of 72 types of Chrysididae (Hymenoptera) belonging to 53 species and subspecies housed in the Swedish Museum of Natural History is given. The lectotypes of Chrysis diversa Dahlbom, 1845, Chrysis soror Dahlbom, 1854, Chrysura sulcata Dahlbom, 1845 and Holopyga amoenula Dahlbom, 1845 are designated. The previous lectotype of Chrysis diversa Dahlbom, 1845 is set aside. Five new synonymies are proposed: Chrysis elegans var. smaragdula Trautmann, 1926 (currently Chrysis elegans ssp. interrogata Linsenmaier, 1959 repl. name for smaragdula Trautmann, nec Fabricius, 1775), syn. n. of Chrysis confluens (Dahlbom, 1845); Chrysis eximia Mocsáry, 1889, syn. n. of Chrysis poecila Mocsáry, 1889; Chrysis pyrrhina Dahlbom, 1845, syn. n. of Chrysis erythromelas Dahlbom, 1845; Chrysis separata Trautmann, 1926, syn. n. of Chrysis lateralis Dahlbom, 1845; Chrysis sicula Abeille de Perrin, 1877, syn. n. of Chrysis erythromelas Dahlbom, 1845. Chrysis serena Radoszkowski, 1891 is the first available name for Chrysis pyrrhina sensu auctorum. Chrysis erythromelas Dahlbom, 1845 is revaluated as valid species. The neotype of Chrysis inaequalis Dahlbom, 1845 is designated in the Linsenmaier collection (NMLS). Illustrations of 34 types are given.

Review of the mounted skins and skulls of the extinct Falkland Islands wolf,Dusicyon australis, held in museum collections

Only nine skins of the extinct Falkland Islands wolf, Dusicyon australis, are currently known in museum collections. In this article we present the results of locating these specimens with a special focus on the origins of two mounted skins in Naturalis Biodiversity Center, Leiden and in the Swedish Museum of Natural History, Stockholm, Sweden. Although only a few specimens were collected, their history is far more complicated than initially thought, and most of their documentary records are fragmented or lost.

Sinea incognita McPherson, a New Species of Assassin Bug from America North of Mexico, with Designations of Lectotypes and Paralectotypes for Sinea complexa and Sinea integra and Analysis and Comparison of the Three Species (Hemiptera: Heteroptera: Reduviidae: Harpactorinae)

The reduviid genus Sinea presently is represented in America north of Mexico by 10 species, one of which is Sinea complexa Caudell. This species has been listed from California east to Missouri and Illinois. In fact, it does not occur in Missouri and Illinois but is limited primarily to the West and Southwest. A new species, Sinea incognita McPherson, described herein, occurs from Maryland south to Georgia and west to Kansas and Texas. It closely resembles S. complexa, for which we provide distinguishing characters; J.E.M. designates a male lectotype and female paralectotype for Caudell's syntypes. A third species, Sinea integra Stål, currently known only from Mexico, shares with S. incognita and S. complexa the presence of spines and tubercles on both lobes of the pronotum rather than just on the anterior lobe as is typical of other Sinea spp. Because we discuss the three species in this article, and Stål did not designate a holotype for either of his two syntypes of S. integra (a male and female) deposited in the Swedish Museum of Natural History, J.E.M. also designates a male lectotype and female paralectotype for this species.

Review of the New Caledonian species of Acritoptila Wells, 1982 (Trichoptera, Insecta), with descriptions of 3 new species

We review the New Caledonian representatives of the Australasian endemic hydroptiline genus Acritoptila, based on examination of a considerable collection of material in the Swedish Museum of Natural History and of types of previously established species. A key for identification of males is given and includes 3 species newly described here: A. parallela sp. n., A. forficata sp. n. and A. macrospina sp. n. For all New Caledonian species, male genitalia are illustrated, and for 5 associated females, distinctive features are illustrated and described.

Absorption of light by exchange coupled pairs of tetrahedrally coordinated divalent manganese in the helvite-genthelvite solid solution

Periodico di Mineralogia (2011), 80, 1 (Special Issue), 105-111 - DOI: 10.2451/2011PM0008 Special Issue in memory of Sergio Lucchesi Absorption of light by exchange coupled pairs of tetrahedrally coordinated divalent manganese in the helvite-genthelvite solid solution Ulf Halenius Department of Mineralogy, Swedish Museum of Natural History, Stockholm, Sweden ulf.halenius@nrm.se Abstract Intensified colours in the helvite-genthelvite solid solution series are demonstrated by means of single crystal optical absorption and electron microprobe techniques to be due to absorption of light by exchange coupled IV Mn 2+ - IV Mn 2+ pairs. The absorption bands caused by the pair transitions occur at energies, 21100, 22600, 23800, 26800 and 28400 cm -1 , that are comparable to those recorded for spin-forbidden single ion transitions in IV Mn 2+ , but the absorption coefficients of the bands are proportional to the square of the Mn-contents of the samples instead of simply showing a Lambert-Beer relationship to the Mn-content. The helvite structure, comprising four corner sharing MnO 3 S tetrahedra with a common sulphur anion apex, represents a favourable situation for formation of exchange coupled 3d-cation pairs. However, several common Mn-rich minerals, as, e.g., rhodonite, have comparably favourable structures that contain corner, edge or face sharing 3d-cation centred polyhedra. Consequently, may Mn 2+ -Mn 2+ pair absorption be a frequent cause for colour intensification in minerals. Key words : helvite; genthelvite; electronic spectroscopy; electron microprobe analyses.

Paleocene flora from Seymour Island, Antarctica: revision of Dusén’s (1908) angiosperm taxa

The Paleocene flora from Seymour Island, Antarctica, is one of the most diverse floras of this age in the Southern Hemisphere. First collected on the Swedish South Polar Expedition (1901–1903), it was described by Dusén in 1908 as having 87 leaf taxa. Forty-seven angiosperm taxa were described and/or illustrated. Many species are based on single specimens, and the flora has not been re-examined in its entirety since it was first described. This study is the first reassessment of the flora updating the original research using current methodologies, and permitting evaluation of the flora in the context of modern ideas on plant evolution and palaeogeography. This paper continues the revision of the material first studied by Dusén; a previous paper described the ferns and gymnosperms; here we describe the angiosperms. The revision is based on the original collections held at the Swedish Museum of Natural History, together with the first major new collections held at the British Antarctic Survey. Among the taxa recognized by Dusén, we recognize only three entire-margined and 11 tooth-margined angiosperms. This revision to 14 species notably lacks the two tropical elements originally described from the flora, Mollinedia seymourensis and Miconiiphyllum austral. Hence, its status as a ‘Mixed Flora’ comes into question and influences climatic interpretations based on Gondwanan floras.

Here we report fossilized filamentous microorganisms from subseafloor basalts interpreted as fossilized fungal hyphae, probably Dikarya, rather than fossilized prokaryotes. The basalts were collected during the Ocean Drilling Program Leg 197 at the Emperor Seamounts, North Pacific Ocean, and the fossilized fungi are observed in carbonate-filled veins and vesicles in samples that represent a depth of ∼150 m below the seafloor. Three-dimensional visualizations using synchrotron-radiation X-ray tomographic microscopy show characteristic fungal morphology of the mycelium-like network, such as frequent branching, anastomosis, and septa. Possible presence of chitin in the hypha walls was detected by staining with Wheat Germ Agglutinin conjugated with Fluorescein Isothiocyanate and examination using fluorescence microscopy. The presence of fungi in subseafloor basalts challenges the present understanding of the deep subseafloor biosphere as being exclusively prokaryotic.

Paleocene flora from Seymour Island, Antarctica: revision of Dusén's (1908) pteridophyte and conifer taxa

The Paleocene flora from Seymour Island, Antarctica, first collected by Nordenskjöld on the Swedish South Polar Expedition (1901–1903), was described by Dusén (1908) as having 87 leaf taxa making it one of the most diverse floras of this age in the Southern Hemisphere. The original descriptions of these leaf impressions included 37 pteridophytes and one conifer. Many species identified by Dusén were based on single fragmentary specimens. Major new collections housed at the British Antarctic Survey (Cambridge, UK), together with the original collections held at The Swedish Museum of Natural History, form the basis for a taxonomic revision of the flora. This paper concentrates on the pteridophytes and conifers. The diversity is considerably reduced from Dusén's estimates with just three ferns (Cladophlebis aemulans, Cladophlebis seymourensis, Sphenopteris angustiloba) and two conifers (Araucaria imponens, Elatocladus seymourensis) recognized.

Långbanshyttanite, a new low-temperature arsenate mineral with a novel structure from Långban, Sweden

The new mineral langbanshyttanite was discovered in a specimen from the Langban mine (59.86°N, 14.27°E), Filipstad district, Varmland County, Bergslagen ore province, Sweden. Associated minerals are calcite, Mn-bearing phlogopite, spinels of the jacobsite-magnetite series, antigorite and trigonite. The mineral is named after the old name of the mine, smelter and mining village: Langbanshyttan. Langbanshyttanite is transparent, colourless. It occurs in late-stage fractures or corroded pockets, forming soft, radial and random aggregates (up to 1 mm) of acicular crystals up to 5 × 20 × 400 μm. D calc is 3.951 g/cm 3 . The new mineral is biaxial (+), α = 1.700(5), β = 1.741(5), γ = 1.792(5), 2V (meas.) ≈ 90°, 2V (calc.) = 86°. Dispersion is strong, r v . The IR spectrum is given. The chemical composition is (electron microprobe, mean of five analyses, wt%): PbO 44.71, MgO 3.79, MnO 13.34, FeO 1.89, P 2 O 5 0.65, As 2 O 5 22.90, H 2 O (determined by gas chromatographic analysis of the products of ignition at 1200 °C) 14.4; total 101.68. The empirical formula based on 18 O atoms is: Pb 1.97 Mn 1.85 Mg 0.93 Fe 0.26 (AsO 4 ) 1.96 (PO 4 ) 0.09 (OH) 3.87 ·5.93H 2 O. The simplified formula is: Pb 2 Mn 2 Mg(AsO 4 ) 2 (OH) 4 ·6H 2 O. Single-crystal diffraction data obtained using synchrotron radiation indicate that langbanshyttanite is triclinic, P 1, a = 5.0528(10), b = 5.7671(6), c = 14.617(3) A, α = 85.656(14), β = 82.029(17), γ = 88.728(13)°, V = 420.6(2) A 3 , Z = 1, and is a representative of a new structure type. In the structure, edge-sharing MnO 2 (OH) 4 octahedra form zig-zag columns that are linked by isolated AsO 4 tetrahedra. Pb cations having six-fold coordination are located between the AsO 4 tetrahedra. Isolated Mg(H 2 O) 6 octahedra are located in the inter-block space. The strongest lines of the powder diffraction pattern [ d , A ( I , %) ( hkl )] are: 14.48 (100) (001), 7.21 (43) (002), 4.969 (34) (100, 101), 4.798 (28) (003), 3.571 (54) (112, 1-1-1, 01–3, 11-1), 2.857 (45) (020, 021, 114), 2.800 (34) (11-3). Parts of the holotype specimen are deposited in the Fersman Mineralogical Museum of Russian Academy of Sciences, Moscow, Russia, with the registration number 4032/1 and in the collections of the Swedish Museum of Natural History, Stockholm, Sweden, under catalogue number NRM 20100076.
