Saarinen, K., Jantunen, J. & Pekkarinen, A. 2002: Herhiläinen levinnyt Kaakkois-Suomeen vuosina 2000-2001. [Expansion of the hornet (Vespa crabro L.) to SE Finland]. (Hymenoptera, Vespidae). — Sahlbergia 7: 1-5. Helsinki, Finland, ISSN 1237-3273.

Between 2000 and 2001, the hornet has rapidly expanded to SE Finland. Two inquiries in regional newspapers, combined with other observations resulted in some 190 individuals and 17 nests in 12 communities in the area. The invasion was expected due to the warm summers in the 1990s in SE Finland and is connected with the species’ recent expansion in the adjacent areas on the Karelian Isthmus. The hornet is considered an endangered species in Finland.

The leafhopper species Paralimnus rotundiceps (Lethierry, 1885) is reported from a sandy shore in Ok: Manamansalo where three males were collected in the summer 2001 with yellow-traps. The record is the northernmost known from Europe. All previous records from this region are more than 50 years old.

Hirvenoja, M. 2002: The fauna in two cold springs and in an epirhithral pool in southern Finland. — Sahlbergia 7: 7-25. Helsinki, Finland, ISSN 1237-3273.

Observations were made on the macrofauna of two cold springs (eustatic akratopegs): a mes-oligotrophic limnocrene and a rheocrene; a little eutrophied epirhithral pool was also studied, all north-northeast of the town Riihimäki, in southern Finland. The number of species found in each varied between 7 and 33 and the approximate number of macrofauna between 2500 and 4500 indiv./m2. A state of near xenosaprobity has been estimated to prevail in the rheocrene and a state of oligosaprobity in the epirhithral pool. Probably because of the conditions in winter, the fauna in the limnocrene studied contains numerous species that are known to have a beta-mesosprobic indication value. A small amelioration in the composition of the fauna was observed after a dig of the limnocrene. The felling of timber around the limnocrene seemed not cause negative changes in its fauna. The article illustrates the emergence (phenology) of the Chironomidae in the limnocrene and describes the larva of Micropsectra (Lundstroemia) fusca (Meigen) (Diptera, Chironomidae). Dixella naevia (Peus) (Diptera, Dixidae) and Chironomus luridus Strenzke (Diptera, Chironomidae) are confirmed to be new to the fauna of Finland.

Haarto, A. 2002: Two trips to collect hoverflies (Diptera, Syrphidae) in the mountains of Kilpisjärvi in Finnish Lapland. — Sahlbergia 7: 26-32. Helsinki, Finland, ISSN 1237-3273.

Two trips for collecting hoverflies to Finnish Lapland (province Le) were made, one to the Urttas area in 1998, and the other one to the Pumbovarri area in 2001. Four hoverflies were recorded as new to the Finnish fauna: Platycheirus nigrofemoratus Kanervo and Parasyrphus groenlandicus (Nielsen), were found in the Urttas area. Platycheirus ramsarensis Goeldlin, Maibach & Speight and Platycheirus subordinatus Becker were found in the Pumbovarri area. Altogether 29 species were collected from the two main research areas and 6 more species near the mountain Saana.

Biström, O. & Rassi, P. 2002: Ampiaisloisikan (Metoecus paradoxus) esiintyminen Suomessa (Coleoptera, Rhipiphoridae). — Sahlbergia 7: 33-34. Helsinki, Finland, ISSN 1237-3273.

The occurrence of Metoecus paradoxus (Linnaeus) (Rhipiphoridae, wedge-shaped beetles) in Finland is reviewed. Some recent records and long periods of absence indicate fluctuations in the Finnish population of the species. A new province record of the species (Ta: Tuulos 678:38) expands the known range of the species northwards with some 60 kilometers.

The species of Hymenoptera Aculeata from Finland until 31.12.2002 and their known distribution are listed. After the publication of the previous checklist, the number of recorded species has increased by 22, the present total number being 624, not including indoor and imported species. All changes with respect to the previous checklist are briefly annotated.

The latest checklist of North European Coleoptera was published in 1992, additions and corrections to it in 1997, and they are now updated with information on new distributional records for the different countries, and with taxonomic and nomenclatural changes. All these additions and corrections are based on published papers.

Two species of Feather-wing beetles, Acrotrichis lucidula Rosskothen and A. sjobergi Sundt are reported from Finland for the first time. Descriptions of the collecting sites are given and some diagnostic characters are described and illustrated.

Clayhills, T. 2002: Sarvijäärien Stenostola ferrea (Schrank) ja S. dubia (Laicharting) esiintyminen Suomessa [The occurrence of the long-horned beetles Stenostola ferrea (Schrank) and S. dubia (Laicharting) in Finland] (Coleoptera, Cerambycidae). — Sahlbergia 7: 100. Helsinki, Finland, ISSN 1237-3273.

All specimens of Stenostola Dejean from Finland have been considered to belong to S. ferrea (Schrank). However, it seems obvious that this is due to former misidentifications and the species occurring in Finland is S. dubia (Laicharting). The differences between the two taxa are discussed, though their status as separate species seems somewhat dubious.

Some records of rare beetles from Ta: Pälkäne and Åland islands (Al) are presented. Bagous petro was found from second place in Finland and Ceutorhynchus hirtulus has been regarded as a species disappeared from Finland.

The first Finnish record of Sigalphus irrorator (Fabricius, 1775) is reported. One male specimen was caught in a yellow trap in Sipoo, southern Finland.

A new record of the siricid wasp Urocerus fantoma (Hymenoptera, Siricidae)

Urocerus fantoma (Fabricius) had not been recorded from Finland after the year 1955, and it was evaluated as regionally extinct in Finland. One female was, however, found in August 2001 in Järvenpää, southern Finland. The specimen was found as freshly dead on the pavement in the middle of the town. There are old conifers growing near the place, and most propably the specimen had developed somewhere in the vicinity.
