Várkonyi, G. & Jussila, R. 2017: Kaksi Suomelle uutta siroahmasta (Hymenoptera, Ichneumonidae, Anomaloninae) [Two anomalonine (Hymenoptera, Ichneumonidae) species new to Finland]. – Sahlbergia 23(1): 2–6. Helsinki, Finland, ISSN 2342-7582.

(Gravenhorst, 1829) and Trichomma fulvidens Wesmael, 1949 (Ichneumonidae, Anomaloninae) are reported from Finland for the first time. Both species are likely to have recently spread to the southern part of the country. Diagnostic characters for species identification are given and host associations are discussed.

Kahanpää, J. 2017: Jäärä Tetropium gabrieli Weise, 1905 tavattu lehtikuusimetsästä Suomessa (Coleoptera: Cerambycidae) [Tetropium gabrieli Weise, 1905 (Coleoptera: Cerambycidae) found in a larch forest in Finland] – Sahlbergia 23(1): 7–8. Helsinki, Finland, ISSN 2342-7582.

The forest pest beetle Tetropium gabrieli Weise, 1905 has expanded its range in Europe during the last several decades. The first Scandinavian records were of specimens imported with larch timber in the and 1980s and 90s. T. gabrieli has since gained a foothold in Swedish larch forests. An adult specimen of Tetropium gabrieli was collected in June 2015 from a 170 year old larch forest in Finnish North Karelia (Kitee, Puhos, 62°05’ N, 29°56’ E), strongly suggesting that this larch-killing longhorn beetle is now breeding also in Finland.

Martikainen, P. 2017: Tuulihaukanpönttöjen kovakuoriaiset (Coleoptera). [Beetles (Coleoptera) in the nest boxes of kestrel (Falco tinnunculus)]. – Sahlbergia 23(1): 9–13. Helsinki, Finland, ISSN 2342-7582.

I collected beetles from ten nest boxes of kestrel (Falco tinnunculus) in Southern Finland during 2009-2016. All the nest boxes were attached to walls of old barns in agricultural environments. The beetles were caught using open, shallow plastic boxes, covered by 6 mm iron mesh, and half-filled with water, detergent and sea salt. Traps were placed in the nest boxes only after successful breeding, when the fledglings had left the nest. Altogether there were samples from 23 ”trap seasons”. The samples contained 40 species and 370 individuals of beetles. The most frequent ones were staphylinid species Atheta vaga, Phyllodrepa nigra and Dexiogyia forticornis, and histerid species Carcinops pumilio and Gnathoncus rotundatus. One threatened species (vulnerable Gnathoncus nidorum) and two near-threatened species (Ptinus podolicus (Anobiidae) and Cryptophagus fallax (Cryptophagidae)) were observed. In addition, the samples contained several rarely observed species associated with bird nests. The trap described here can be used in large nests boxes of other birds, too, such as owls.

Raekunnas, M., Vilén, J., Paukkunen, P. & Leinonen, P. 2016: Okakärpäshukka Ectemnius spinipes (A. Morawitz, 1866) (Hymenoptera: Crabronidae) löydetty Suomesta. [Ectemnius spinipes (A. Morawitz, 1866) (Hymenoptera: Crabronidae) found from Finland.]. – Sahlbergia 23(1): 14–16. Helsinki, Finland, ISSN 2342-7582.

The digger wasp Ectemnius spinipes is reported as new to Finland on the basis of 13 males and 13 females collected in 2012–2015 from Lappeenranta and Parikkala, south-eastern Finland. The specimens were caught mainly by window traps from dead trunks of aspen (Populus tremula), birch (Betula) and great sallow (Salix caprea), which probably contained nests of the species. The distribution of E. spinipes is patchy in mountainous regions of southern and central Europe and extends through Russia to China and Japan. The distinguishing features of E. spinipes are compared with its closest European relatives, E. cephalotes and E. fossorius.

Vikberg, V. 2017: Two sawflies new for the fauna of Russia, one being new for Europe and the western Palaearctic region (Hymenoptera: Symphyta: Heptamelidae and Tenthredinidae). – Sahlbergia 23(1): 17–19. Helsinki, Finland, ISSN 2342-7582.

Two species of sawflies are reported as new for fauna of Russia. Ten females of Heptamelus ochroleucus (Stephens) (Heptamelidae) were reared in Moscow from larvae found on Athyrium filix-femina. One slightly aberrant female of Heptapotamius simini Malaise (Tenthredinidae) was found on a salt steppe 4 km S of Viazovka, Radistchevo district, Uljanovsk Region, European Russia. The sawfly species is new for Europe and western Palaearctic region.

Kaksi Venäjän faunalle uutta sahapistiäistä esitetään. Heptamelus ochroleucus (Stephens) (Heptamelidae) -lajin naaraita on kasvatettu toukista soreahiirenportaalta (Athyrium filix-femina) Moskovassa. Lajin Heptapotamius simini Malaise (Tenthredinidae) hieman aberratiivinen naaras löytyi suola-arolta Radistchevosta Uljanovskin alueelta Euroopan puoleiselta Venäjältä. Tämä laji on uusi Euroopalle ja Länsipalearktiselle alueelle.

Salmela, J. & Holopainen, R. 2017: Äkämäsääski Neurepidosis gracilis Spungis Suomelle uutena Tampereelta (Diptera, Cecidomyiidae). [Neurepidosis gracilis Spungis, new to Finland, from Tampere (Diptera, Cecidomyiidae).] – Sahlbergia 23(2): 2–4. Helsinki, Finland, ISSN 2342-7582.

A Porricondylinae gall midge species Neurepidosis gracilis Spungis, 1987 is reported for the first time from Finland. Larvae of the species were collected from pieces of coarse forest detritus and were reared to adults. The collecting site in South Finland, Tampere, was an aspen dominated boreal forest. Members of the genus Neurepidosis Spungis are rarely collected and poorly known; N. gracilis was hitherto known from Latvia and South Sweden only. Based on our record presented here, N. gracilis is a forest detritus associated species. The main diagnostic characters of the species are present in the male hypopygium: ventroapical margin of gonocoxites is slightly concave and gonostylus has a large, hyaline basal lobe.

Kahanpää, J., Kakko, I. & Haarto, A. 2017: Lejops vittatus (Meigen, 1822), Suomelle uusi kukkakärpänen (Diptera: Syrphidae). [Lejops vittatus (Meigen, 1822), a hoverfly new to the Finnish insect fauna (Diptera: Syrphidae)] – Sahlbergia 23(2): 5–7. Helsinki, Finland, ISSN 2342-7582.

Three specimens of the rare hoverfly Lejops vittatus (Meigen, 1822) were found during the first days of July 2016 on a seashore meadow near the Husö Zoological Station, Åland, Finland. The species is new to Finland. L. vittatus is very local and mostly rare in Northern Europe, with less than twenty known localities—mostly single specimen records—in Sweden and Denmark. The flies were observed flying among clubrushes (Bolboschoenus sp., pr. B. maritimus) near the water margin of a grazed coastal meadow. The salinity of the Baltic Sea in this area is around 5-6 ‰ and tides are negligent. These records represent the hitherto northernmost occurences of Lejops vittatus. The presence of several specimens on potentially suitable breeding habitat suggests that the species has a local population on the Åland Islands.

Viitanen, E. 2017: Tipula luna Westhoff, 1879 (Diptera, Tipulidae) palasi takaisin Suomen lajistoon [Tipula luna Westhoff, 1879 (Diptera, Tipulidae) returned to the Finnish fauna] – Sahlbergia 23(2): 8–9. Helsinki, Finland, ISSN 2342-7582.

Tipula luna Westhoff (Diptera, Tipulidae) palasi Suomen lajistoon. Yksi koirasyksilö talletettiin Ahvenanmaalta 17.6.2017. Tipula luna on aikaisemminkin ilmoitettu Suomesta, mutta Terijoen löytöpaikka ei ole Suomen nykyisten rajojen sisäpuolella.

Tipula luna Westhoff, 1879 (Diptera, Tipulidae) returned to the Finnish fauna. One male specimen was collected in Åland Islands on June 17th 2017. Tipula luna was previously reported from Finland based on a specimen from Terijoki on the Karelian Isthmus. Terijoki has not been within Finnish borders since the Second World War.

Clayhills, T. 2017: Reflections on the description of Glischrochilus tremulae Clayhills, Audisio & Cline 2016 (Coleoptera: Nitidulidae) from Finland, with new information on its distribution. – Sahlbergia 23(2): 10–12. Helsinki, Finland, ISSN 2342-7582.

Due to unexpected mistrust between the two senior authors, the original description of Glischrochilus tremulae Clayhills, Audisio & Cline 2016 came to include some mistakes and errors concerning the collection areas and methods. The misleadingly flat original habitus picture 2 is replaced here with appropriate photos of the new species, and the strangely confused text to pictures 12–13 is corrected. Older unrecognized records of the new species from Finland are listed.

Kerppola, S. 2017: Helsingin Santahaminan petopistiäiset (Hymenoptera: Ampulicidae, Sphecidae, Crabronidae). – Sahlbergia 23(2): 13–21. Helsinki, Finland, ISSN 2342-7582.

The local fauna of digger wasps (Hymenoptera: Ampulicidae, Sphecidae, Crabronidae) in the sudy area Helsinki Santahamina is presented. In total, 68 species have been recorded. This number represents about 44 % of the total number, 155, of digger wasp species recorded in Finland. Comments and photos on some rare species are provided.
