A diagnosis of European Phrudinae is given and a key is presented for Seleucus cuneiformis Holmgren and eleven European species of Phrudinae. Seleucini Vikberg trib. nov. in Ctenopelmatinae is proposed for Seleucus Holmgren. Astrenis nigrifacies Vikberg sp. nov. (Finland, Sweden, England, Scotland, France), A. brunneofacies Vikberg sp. nov. (Finland, Sweden, England, Scotland, Germany, Italy), Phrudus compressus Vikberg sp. nov. (Finland, Sweden) and the males of A. paradoxus (Schmiedeknecht) and P. badensis Hilpert are described for the first time. All other species are redescribed, and new distributional data are reported. The dentation of the claws and the form and location of modified sensory structures on the subbasal flagellomeres are used as taxonomic characters. Pygmaeolus nitidus (Bridgman), Astrenis nigrifacies, A. brunneofacies, Phrudus defectus Stelfox, P. compressus and P. badensis were found to be associated with ageing logs of Pinus sylvestris L. and Picea abies (L.) H. Karst.

We report records of 25 species of aphids collected from four species of woody plants (Pinus sylvestris, Picea abies, Betula pubescens and B. pendula) at 50 study sites in Northern Europe, located from 59° to 70° N and from 10° to 60° E. Critical evaluation of earlier publications demonstrated that in spite of the obvious limitations of our survey, the obtained information substantially contributed to the knowledge of the distribution of aphids in North European Russia, including Murmansk oblast (103 species recorded to date), Republic of Karelia (58 species), Arkhangelsk oblast (37 species), Vologda oblast (17 species) and Republic of Komi (29 species). We confirm the occurrence of Cinara nigritergi in Southern Karelia; Pineus cembrae, Cinara pilosa and Monaphis antennata are for the first time recorded in Norway.

The annotated list of hepatics of the Sochi National Park includes 80 taxa. It is based on literature records and identification of 250 specimens collected by the authors. Scapania obcordata (Berggr.) S. W. Arnell and Calypogeia fissa (L.) Raddi var. intermedia (C. E. O. Jensen) Jorg. are new for the Caucasus, 17 taxa are new for Krasnodar Territory, 41 hepatics are reported for the first time for the park. New localities of 3 red-listed European species and of 6 species included in the Red Data Book of Krasnodar Territory are cited, indicating significant conservation value of the reserve.

AbstractThe lichen genus Lecanactis Körb. in Tasmania comprises six species: L. abietina (Ach.) Körb., which is widespread and pan-temperate; L. latispora Egea & Torrente and L. neozelandica Egea & Torrente, both shared with New Zealand and with the former recorded here from the Auckland Islands for the first time; L. mollis (Stirt.) Frisch & Ertz, shared with Victoria and New Zealand; L. aff. dilleniana (Ach.) Körb., a European species recorded provisionally for Tasmania on the basis of several sterile collections; L. scopulicola Kantvilas, which is described here as new to science and apparently a Tasmanian endemic. This new taxon occurs in rocky underhangs and is characterized by a thick, leprose thallus containing schizopeltic acid, and 3-septate ascospores, 19–30 × 4.5–6 μm. Short descriptions and a discussion of distribution and ecology are given for all species. A key for all 11 Australian species of the genus is provided, including L. subfarinosa (C. Knight) Hellb. and L. tibelliana Egea & Torrente, which are recorded for Australia for the first time, and L. platygraphoides (Müll.Arg.) Zahlbr., a first record for New South Wales. Lecanactis spermatospora Egea & Torrente and L. sulphurea Egea & Torrente are also included.
