Arachnologische Mitteilungen 54

Arachnologische Mitteilungen / Arachnology Letters 54: 59-62 Karlsruhe, September 2017 The last checklist of harvestmen including all the Nordic countries was published by Stol (2007). He listed 17 species from Norway, 20 species from Sweden, 12 species from Fin- land, 19 species from Denmark, four species from Iceland and five from the Faroe Islands. Since 2007 the knowledge of the Opiliones fauna in the Nordic countries has increased. The number of species currently reported from each country is: 23 species known from Norway, 21 from Sweden ( Jonsson 2013, pers. comm. 2017), 17 from Finland (Uddström et al. 2013, Uddström & Rinne 2016a, 2016b), 25 from Denmark (Eng- hoff et al. 2014).The species numbers of the Faroe Islands and Iceland have remained, to our knowledge, unchanged compa- red to Stol (2007). Material and methods In total 20 localities in South Norway were visited during the period from 11 th to 22 nd August 2015. Our priority was a study of ant communities (Hymenoptera: Formicidae) and the survey of the Opiliones fauna was an additional activity. The collected specimens have all been sampled manually.The nomenclature used in this paper, as well as the identification of material, is based on Martens (1978), Martens & Schön- hofer (2016) and Wijnhoven (2009). The EIS numbers and the Norwegian county part abbre- viations follow the system as presented in Norwegian Journal of Entomology (NJE 2015).

We present a revised checklist of harvestmen (Opiliones) covering all the Nordic countries, including Iceland and the Faroe Islands. Altogether 31 species from 18 genera and four families are currently known, of which 23 are from Norway, 21 from Sweden, 17 from Finland, 25 from Denmark, five from the Faroe Islands and four from Iceland. Five species are documented for the first time in Norway: Lacinius dentiger (C. L. Koch, 1847), Lacinius horridus (Panzer, 1794), Opilio saxatilis C. L. Koch, 1839, Leiobunum blackwalli Meade, 1861 and Leiobunum limbatum L. Koch, 1861.
