New moth flies for eastern Fennoscandia (Diptera, Psychodidae)
Salmela, J. 2005: New moth flies for eastern Fennoscandia (Diptera, Psychodidae). [Itäiselle Fennoskandialle uusia perhossääskiä (Diptera, Psychodidae)]. — Sahlbergia 10:1–3.
Four moth flies (Diptera, Psychodidae) are reported for the first time from Finland and Russian Karelia. Logima satchelli (Quate, 1955) and Logima erminea (Eaton, 1898) were caught from Espoo (N) and two rarely caught and poorly known species Sciria advena and Katamormia acuminata are here reported for the first time from northern Europe. Dendrolimnobiontic Sciria advena (Eaton, 1893) was collected from Finland, Savonranta (Sb) Raatelamminsalo old-growth forest. Hollow aspen (Populus tremula) trees may support the populations of Sciria advena in boreal Fennoscandia. Katamormia acuminata (Strobl, 1901), a species known from the type material only, was collected near a forest brook in Russian Karelia, Paanajärvi National Park.
Agrypnia sahlbergi (McLachlan, 1880) rediscovered from Finland (Trichoptera, Phryganeidae)
Salmela, J. 2005: Agrypnia sahlbergi (McLachlan, 1880) rediscovered from Finland (Trichoptera, Phryganeidae). [Tundrahiidekäs Agrypnia sahlbergi (McLachlan, 1880) uudelleenlöydetty Suomesta (Trichoptera, Phryganeidae)]. — Sahlbergia 10: 4–6.
New findings of the threatened caddisfly Agrypnia sahlbergi from Finland are reported. The species was collected with Malaise traps in two localities in Sarmitunturi wilderness area (InL: Inari). The trapping localities are shortly described and co-occurring caddisflies are listed.
First record of Georthocladius luteicornis (Diptera: Chironomidae) in Finland
Raunio, J. & Langton, P. H. 2005: First record of Georthocladius luteicornis (Diptera: Chironomidae) in Finland. — Sahlbergia 10: 7–9.
A pupal exuviae of the chironomid Georthocladius luteicornis (Goetghebuer) was collected in early May 2004 from the large boreal river Kymi, southeast Finland. This was the first time the species has been found in Scandinavia outside Norway. The species has previously been recorded mainly from central and western parts of Europe inhabiting typically small lentic waters. Our observation suggests that the species’ distribution extends further northeast in Europe than understood before and that the species is to be found also in large rivers. The distribution and ecology of the species and morphological characteristics of the pupal exuviae are discussed.

The Finnish records of Rhagionidae: Chrysophilus splendidus (Meigen), Asilidae: Epitriptus arthriticus (Zeller), Epitriptus cingulatus (Fabricius), Choerades fimbriata (Meigen) and Hybotidae: Drapetis incompleta Collin, 1926 are considered dubious, and they are not included in the checklist. The total number of species found from Finland in these families is now 483.
Harvinaisia maakiitäjäisiä Helsingin Vuosaaresta (Coleoptera, Carabidae)
Perkiömäki, J. & Rutanen, I. 2005: Harvinaisia maakiitäjäisiä Helsingin Vuosaaresta. [Records of rare carabids from Vuosaari, Helsinki (Coleoptera, Carabidae)]. — Sahlbergia 10: 28–29.
The ground beetle species Badister sodalis (Duftschmid, 1812) is for the first time reported from Finland based on three specimens collected on the edge of a moist meadow in Vuosaari, Helsinki (N). The habitat of this species is shortly described. The finds of another rare carabid, Chlaenius nitidulus (Schrank, 1781), already earlier reported from Finland, are completed. For both these species Vuosaari is the only known finding place in Finland. The site of C. nitidulus is nowadays built up and this species is in all probability extinct in Finland.
Orakärpänen (Urophora cardui) ja sen kiilukaisloiset Etelä-Suomessa (Hymenoptera: Chalcidoidea: Eulophidae, Eupelmidae, Eurytomidae, Pteromalidae, Torymidae)
Vikberg, V. 2005: Orakärpänen (Urophora cardui) ja sen kiilukaisloiset Etelä-Suomessa [The thistle stem gall-fly (Urophora cardui) and its chalcidoid parasitoids in southern Finland (Hymenoptera: Chalcidoidea: Eulophidae, Eupelmidae, Eurytomidae, Pteromalidae, Torymidae)]. — Sahlbergia 10: 30–49.
Stem galls caused by Urophora cardui (Linnaeus) (Diptera, Tephritidae) on Cirsium arvense (L.) Scop. were collected in 1983-2004 in southern Finland. A total of 1355 specimens of 8 chalcidoid parasitoids were reared from them. The most frequent species (61.6 % of parasitoid records) was Eurytoma serratulae (Fabricius) (Eurytomidae), a monophagous endoparasitoid of U. cardui larva. In South Häme (Ta) in 1995-2003 64-82 % of the gall samples were infested by it. E. serratulae showed as good a dispersion capacity as the host, and up to autumn 2003 both had dispersed 144 km North-West and 171 km North from Helsinki where U. cardui was in Finland first detected in 1981. The mean annual dispersion rate was 6.5-7.8 km. Three exophagous parasitoids which also have other hosts were considerably less frequent: Pteromalus elevatus (Walker) (Pteromalidae) (18.4 %), Eurytoma robusta Mayr (12.5 %) and Torymus chloromerus (Walker) (Torymidae) (4.5 %). One female of Pteromalus hieracii (Thomson) emerged in Vantaa from the galls; this species occurs normally in stem galls of Aulacidea hieracii (Bouché) (Hymenoptera, Cynipidae) on Hieracium umbellatum L. The overwintered galls were attacked again by Pteromalus elevatus, and occasionally by Eupelmus (Macroneura) vesicularis (Retzius) (Eupelmidae), twice by the gregarious Pronotalia carlinarum (Szelényi & Erdös) (Eulophidae) and once possibly by Cyrtogaster vulgaris Walker (Pteromalidae).
Five species of log midges (Diptera, Cecidomyiidae: Porricondylinae) new to Finland
Penttinen, J. & Siitonen, J. 2005: Five species of log midges (Diptera, Cecidomyiidae: Porricondylinae) new to Finland. – Sahlbergia 10: 50–53.
Five gall midge species of the subfamily Porricondylinae are reported for the first time from Finland. Monepidosis pectinata Mamaev, 1966; Paratetraneuromyia vernalis Spungis, 1987; Porricondyla lutescens Spungis, 1981 and Pseudepidosis trifida Mamaev, 1966 were caught by Malaise trapping from Norway spruce-dominated old-growth forests in central Finland (Tb), and Epidosis modesta (Spungis, 1981) from a burnt clear-cut site in Evo region, southern Finland (Ta). Only 33 species of Porricondylinae were previously known from Finland, but the real number of species is likely to be well over 100.
Notes on mating swarms of black flies (Diptera: Simuliidae) in northern Finland
Ilmonen, J. 2005: Notes on mating swarms of black flies (Diptera: Simuliidae) in northern Finland. – Sahlbergia 10: 54–58.
Mating swarms of black flies (Diptera: Simuliidae) were recorded in hilltops in northern Finland. In August 2003, mating swarms comprising mainly male Simulium tuberosum (Lundström) were recorded. Individuals of Simulium angustipes Edwards, S. aureum Fries, S. ornatum species group and S. rostratum (Lundström) occurred sporadically in the swarms. In July 2003, one mating swarm comprising Metacnephia saileri (Stone), S. vernum Macquart, and S. tuberosum was recorded. Hilltopping behaviour is an especially rarely documented form of aerial mating in black flies. Similar mating swarms of palearctic Metacnephia species to those presented here have not been recorded previously.
Polypore-inhabiting beetles of four protected forests in South Häme, Central Finland
Schigel, D. S. 2005: Polypore-inhabiting beetles of four protected forests in South Häme, Central Finland. – Sahlbergia 10: 59-62.
Beetles living on polypores show preferences to hardness, moisture and other characteristics of fungal substrates. This topic was studied in four protected forests in South Häme, Central Finland (Lammi Biological Station Reserve, Kotinen Virgin Forest, Metsäksensoidinmaa Nature Reserve, and Vesijako Strict Nature Reserve). On 21 polypore species 30 such beetle species were found. New larval substrates are reported for three beetle species, Perenniporia subacida for Cis nitidus, Trametes velutina for Cis hispidus, and Postia stiptica for Hallomenus binotatus. Clambus nigrellus, a rare beetle species in Finland, is attracted to a near-threatened polypore Postia guttulata.
Sinirautamehiläinen Xylocopa violacea (Linnaeus) löydetty importtina Kuopiosta (Hymenoptera, Apidae)
Teräs, I. & Savolainen, E. 2005: Sinirautamehiläinen Xylocopa violacea (Linnaeus) löydetty importtina Kuopiosta (Hymenoptera, Apidae) [Xylocopa violacea (Linnaeus) found imported in Kuopio, Finland (Hymenoptera, Apidae)]. – Sahlbergia 10: 63-64.
Three females and one male of Xylocopa violacea (Linnaeus) (Hymenoptera, Apidae) were found imported in Sb: Kuopio, Kelloniemi in August, 2004. Earlier only one (imported) female of X. violacea has been recorded from Finland (Sa: Kangasniemi in 1923). At the nearest, the species lives in natural conditions in Poland.
Liorhyssus hyalinus (Fabricius) new to Finnish fauna (Heteroptera, Rhopalidae)
Ollikainen, M. & Rinne, V. 2005: Liorhyssus hyalinus (Fabricius) new to Finnish fauna (Heteroptera, Rhopalidae). – Sahlbergia 10: 65-67.
The hyaline brown bug Liorhyssus hyalinus (Fabricius) is recorded for the first time from Finland. This is also the second record of the species in the Nordic countries.
