Abstract The contribution summarizes previously unpublished data and adds records of newly collected cave-dwelling spiders from the Balkan Peninsula. New data on the distribution of 91 species from 16 families, found in 157 (27 newly established) underground sites (caves and artificial galleries) are reported due to 337 original records. Twelve species are new to the spider fauna of the caves of the Balkan Peninsula. The species Histopona palaeolithica (Brignoli, 1971) and Hoplopholcus longipes (Spassky, 1934) are reported for the first time for the territory of Balkan Peninsula, Centromerus cavernarum (L. Koch, 1872), Diplocephalus foraminifer (O.P.-Cambridge, 1875) and Lepthyphantes notabilis Kulczyński, 1887 are new for the fauna of Bosnia and Herzegovina, Cataleptoneta detriticola Deltshev & Li, 2013 is new for the fauna of Greece, Asthenargus bracianus Miller, 1938 and Centromerus europaeus (Simon, 1911) are new for the fauna of Montenegro and Syedra gracilis (Menge, 1869) is new for the fauna of Turkey. Seventy two new species records are announced for 47 caves with known spider fauna. Thus, the number of spiders established in the Balkan caves was increased up to 410 species. Key words: cave fauna, Balkan countries, new records. Introduction The Balkan Peninsula is a region with an extremely rich and diversified cave fauna. The spider fauna have been comparatively well studied due to the efforts of many araneologists from different countries. Deltshev (2008) had reviewed all available published information so far and a total of 326 species from 115 genera and 31 families of Araneae have been established in the caves of the Balkan Penisula. The recent publications are due to the investigations of Beron (2015, 2016), Bolzern et al. (2013), Bosmans (2009), Bosmans et al. (2013), Deltshev (2011a, b), Deltshev et al.

The present contribution summarizes previously unpublished data and adds records of newly collected cave-dwelling spiders from the Balkan Peninsula in the period 2009 – 2016. Ecol. Mont., 7, 2016, 425-438 NEW DATA ON THE CAVE-DWELLING SPIDERS IN THE BALKAN PENINSULA Material and Methods The material treated herein originates from 152 caves and 5 artificial galleries (Fig. 1 and Table 1) divided into two principal parts. The first part comprises the original collections made in the period 2009 – 2016 during a cave survey covering most of the countries in the Balkan Peninsula (we perceive the peninsula’s boundaries defined in Deltshev (2008)). The second concerns unpublished samples from the collections of the National Museum of Natural History, Sofia (NMNH – Sofia). The spiders have been collected mainly by hand from the walls, under the stones or from the clayish layers of the caves. The material is deposited in NMNH – Sofia. The taxonomic arrangements follow World Spider Catalog (2016). The ecological classification follows Sket (2008). The approximate geographical coordinates are given in decimal degrees (rounded to the second decimal place). Figure 1. Distribution of the studied sites in the territory of the Balkan Peninsula.
