Introduction
Hoverflies (Diptera: Syrphidae) are a diverse and widespread family in the world. More than 800 species are registered in Europe (Speight 2012). For Slovenia 288 species have been listed so far (De Groot & Govedič 2008, de Groot et al. 2010).
The aim of present study was to increase the knowledge of hoverfly distribution in Slovenia by examining the specimens collected from additional sites in June 2008.
Material and Methods
In total 919 hoverfly specimens collected from 11 locations in the western part of Slovenia (figure 1) were examined. The hoverflies were collected by hand net in the period of 19 to 21 June 2008. The collected specimens cited are deposited in the private collections of the authors, unless otherwise stated.
Identifications were based on Van Veen (2004), unless otherwise stated in the notes on species. Specimens which could not be identified by the authors were identified by other specialists. In the genus Eupeodes a male and a female were not identified due to taxonomic problems.
The species collected are listed below in alphabetical order. The nomenclature is according to Speight (2012); exceptions are stated in the notes on the species. For each species studied, unpublished (new) and published data for Slovenia are listed. For new species to Slovenia, the distribution on the Balkan peninsula is mentioned (Krpač et al. 2001a, Krpač et al. 2001b, Krpač et al. 2009a; 2009b Speight et al. 2010, Vujic 1996, Vujic et al. 2004).
For many species behaviour and flowers visited are mentioned.

These sites are distributed over the biogeographical regions of Slovenia as follows: Alpine region: four Jesenice sites and two Pokljuka sites. Subalpine region: Žejna dolina site. Dinaric region: Volovja Reber, Snežnik, Krim and Podpeč sites. We did not visit the Submediterranean and Subpannonnean regions. The Alpine and Subalpine sites are within high, central mountain ranges. The Dinaric sites are characterised by limestone rock with mostly dry habitats.
Weather conditions influence the number of hoverflies found at a site. At most sites the weather was fine for collecting hoverflies: sunny weather with some clouds, temperatures between 18°C and 25°C and little wind. Less favourable conditions were met at Snežnik (site 6) (completely clouded), Žejna dolina (site 7) (clouded with rain), Krim (site 8) (temperature between 10°C and 15°C), Podpeč (site 9) (above 30°C) and Siječ (site 10) (windy with lower temperatures: 15°C to 20°C).

Notes on the species:
Arctophila bombiforme (Fallen, 1810) New data. Planina pod Golico 2: 2$, 1 $
Published data. Slovenia: De Groot & Govedič (2008) (as A. bombiformis). Biology. Egg laying was observed in a small rivulet in shaded forest (figure 7). The female was flying low over the water and settling on the rocks and moss cushions several times before landing on a moss overgrown rock where it moved slowly backwards to the water to oviposit one visible egg on the moss just above the water level.

Discussion
Our research, conducted during 19-21 June 2008 in Western Slovenia, gave the following results: 158 species collected and 21 species new to the fauna of Slovenia. Eleven sites were visited, four of which could be regarded as parts of one larger site,
Jesenice, and two other sites also as one larger site, Pokljuka. The numbers of collected species per site range from 27 to 68, apart from three sites that were only visited very briefly (two, eight and nine species). Jesenice, with 101 hoverfly species is the richest site in western Slovenia, then Pokljuka follows with 43 species.
The number of recorded species was highly influenced by the weather. Weather circumstances were good for collecting hoverflies at Jesenice sites, Volovja Reber and Veliko Blejsko barje. The numbers of collected specimens and species were negatively affected by the weather at sites Snežnik, Žejna dolina, Krim, Podpeč and Siječ. Especially at Žejna dolina and Podpeč hoverflies were not active due to the weather.
New species for Slovenia were collected at nine investigated localities. Most of them were collected at Volovja Reber (9 species) and Jesenice (8 species). At Snežnik (4 species), Pokljuka (1 species), Podpeško jezero (1 species) and Krim (1 species) only a few species new to Slovenia were found. This could partly be due to less favourable weather conditions at these sites. As many new species were captured at the Volovja reber chalk plateau this would be a good place to look for additional species. The slopes of the Alps probably harbour new species for Slovenia also.
Twenty-nine species are considered as decreasing or threatened in the alpine or continental part of Europe (Speight et al. 2010). Hammerschmidtia ferruginea is threatened in both the continental and Alpine regions. Caliprobola speciosa, Microdon mu-tabilis, Neoascia meticulosa, Pipizella divicoi, Sphaerophoria batava, Psilota anthracina, Xylota tarda and Merodon flavus are decreasing in both regions. Paragus tibialis is locally threatened in the Alpine and continental regions. Chrysotoxum ele-gans, Epistrophe leiophthalma, Eumerus ovatus, Eumerus tricolor, Merodon armipes, Microdon devius, Sphaerophoria taeniata, Sphaerophoria virgata, Sphegina clavata, Sphegina montana, Temnostoma bombylans, and Sericomyia silentis are decreasing only in the continental region. Cheilosia derasa is locally threatened in the continental region. Cheilosia faucis, Cheilosia soror, Chrysogaster solstitialis, Eumerus gran-dis, Eupeodes goeldlini and Xylota tarda are decreasing in the Alpine region. Cheilosia bracusi is locally threatened in the Alpine region (Speight et al. 2010).
Many of the collected species are listed as decreasing or endangered for parts of Europe. This high number might be influenced by the fact that many parts of Slovenia are still relatively unexplored. The presented results clearly show that more investigations are needed to determine the actual state of these species in Slovenia. At the moment it would be wise to regard all sites with decreasing or threatened species as important and valuable areas for the European Syrphidae fauna. Protection of these sites should be given special attention.
During this short trip 158 species were collected. The list of Slovenian Syrphidae was extended from 288 to 309 species.
