Spider Fauna of Island Geojedo (Prov. Gyeongsangnam-do) in Korea

This work was conducted to investigate spider fauna and community structure of Geojedo situated at the southern coast of Gyeongsangnam-do, South Korea. Seventy species of 48 genera belonging to 17 families were identified from 389 collected spiders. Check list of spiders which represent 137 species, 91 genera from 29 families was made from former reports and present work including 4 cosmopolitan species, 6 Holarctic species, 13 Palearctic species and 2 Korean endemic species. Species richness was high in Araneidae (30 species, 21.9%), Salticidae (22 species, 15.8%), Theridiidae (18 species, 12.9%), and Thomisidae and Linyphiidae (10 species, 7.2%) in order. This work might be valuable monitoring to understand the biota of Geojedo and to analyze Korean island ecosystem.
