BIOLOGIJA. 2011. Vol. 57. No. 4. P. 148–158 © Lietuvos mokslų akademija, 2012 The checklist of Lithuanian spiders (Arachnida: Araneae) Marija Biteniekytė*, This paper summarizes data on all spider (Arachnida, Araneae) species found in Lithuania. The list of 445 Lithuanian spiders (Araneae) of 29 families is based on 35 Vygandas Rėlys sources of literature published until 2011. Family names, generic and species nomen clature are in compliance with the classification proposed by N. I. Platnick. All the Department of Zoology, published sources containing information about spider species found in the territory Vilnius University, of Lithuania are provided. Taking into account the described diversity of spider fauna M. K. Čiurlionio str. 21/27, of the neighbouring countries we may expect approximately 100 spider species to be LT-03101 Vilnius, Lithuania recorded in Lithuanian fauna in the future. Key words: Araneae, spiders, checklist, Lithuania, faunistics INTRODUCTION MATERIALS AND METHODS Spiders (Araneae) form one of the largest groups of Arach The main material was collected using pitfall traps [6–10, nida class. 42 751 spider species are described worldwide. 14].
