The problematic taxonomic status of Arge annulata is discussed, and it is recorded for the first time from Germany and Estonia. For Heptamelus dahlbomi (Thomson, 1870) (Heptamelidae): a lectotype is designated for Caenoneura dahlbomi, H. ussuriensis Malaise, 1931 is placed as its junior synonym, Athyrium distentifolium recorded as a new host, and additional distribution data are presented, including the first records from Austria. A lectotype is designated for Heptamelus magnocularis Malaise, 1931, and this species briefly compared with H. dahlbomi.

Larvae of all species are leaf-miners in Ranunculaceae. An identification key to adults is provided, followed by species commentaries which include summarised data on taxonomy, larval host plants, and distribution, with particular reference to Sweden. Whereas identification of some specimens using morphological characters may not be possible, each species apparently has a distinct COI barcode sequence. Pseudodineura heringi (Enslin, 1921) is a new junior synonym of P. parvula (Klug, 1816). Pseudodineura mocsaryi Zombori, 1976 and P. scaligera Zombori, 1979 are new junior synonyms of P. clematidisrectae Hering, 1935. Lectotypes are designated for: Dolerus minutus Hartig, 1837, Pelmatopus clematidis Hering, 1932, P. enslini Hering, 1923, P. heringi Enslin, 1921, and P. mentiens var. konowi Enslin, 1921.

Their larvae develop entirely within the female catkins of Salix species: some species bore in the central stalk, whereas others live outside this and feed mainly on the developing seeds. Eight Palaearctic species are treated here as valid, and a key to these is provided. Males of five species are known. Two new species are described from northern Europe: Euura pohjola sp. n. and E. ursaminor sp. n. First records of E. itelmena (Malaise, 1931) from the West Palaearctic are presented. We propose seven new synonymies: Pontopristia montana Lindqvist, 1961 (junior secondary homonym in Euura) with Euura freyja (Liston, Taeger & Blank, 2009); Pontopristia brevilabris Malaise, 1921, Amauronematus fennicus Lindqvist, 1944, Pontopristia boreoalpina Lindqvist, 1961, Pontopristia punctulata Lindqvist, 1961, and Amauronematus pyrenaeus Lacourt, 1995 with Euura microphyes (Förster, 1854); and Pter...

His large collection is deposited in the Senckenberg Deutsches Entomologisches Institut, Müncheberg, Germany. Following a short biography, we present commentaries on noteworthy specimens from Switzerland and some general and specific characteristics of the Swiss sawfly fauna, based on his collection and database. Twenty sawfly species are recorded for the first time in Switzerland: Aprosthema bifurca, Arge fuscipennis, Cladardis hartigi, Dolerus altivolus, D. brevicornis, D. zhelochovtsevi, Empria fletcheri, Euura amentorum, E. cyrnea, E. longiserra, E. scotonota, Nescianeura noblecourti, Pristiphora depressa, P. luteipes, P. nigricans, Rhogogaster polaris, Taxonus alboscutellatus, Tenthredo semicolon, Tenthredopsis tischbeinii and Calameuta idolon.

If the licence for Lucid 3.5 is lacking, the free version of Lucid 3.3 can be used to run the key. In case of ambiguities or polymorphisms in character states, we conservatively coded these as multiple states. The key contains 90 morphological features with 244 character states, and 68 male and 71 female entities (species or groups).

(Hymenoptera: Cephidae) is described from Brandenburg, eastern Germany, known only from the female holotype. It possesses an unusual combination of “generic” morphological characters, which makes its placement in Stenocephus Shinohara, 1999 provisional. Compared to other Stenocephus species, differences in the morphology of the lancet are particularly striking. Genetic data for S. janseni sp. nov. place it unequivocally in the Hartigiini, but rather distantly from other genera of this tribe which have so far been sequenced. The three previously described Stenocephus species are recorded from the East Palaearctic. No genetic data are currently available for these. Pachycephus nigratus Dovnar-Zapolskij, 1931, comb. restit., is no longer treated as belonging to Phylloecus Newman, 1838, but as a member of the genus in which it was originally described.

Many biodiversity inventories provide limited insight because they focus on a small taxonomic subsample or a tiny geographic area. Here, we report on the size and composition of the Swedish insect fauna, representing roughly half the macroscopic diversity of one of the largest European countries, based on more than a decade of data from the Swedish Taxonomy Initiative and a massive inventory of the country's insect fauna. The fauna is considered one of the best known in the world, but the inventory has nevertheless revealed a surprising amount of hidden diversity: more than 3,000 new species (301 new to science) have been documented so far. We show that three independent extrapolation methods converge on similar estimates of the true size and composition of the true fauna, suggesting that it comprises around 33,000 species...
