Abstract
Information on diversity and distribution of spiders in Libya is limited, due to lack of updates and lack of a systematic checklist for these arthropods in the country. Here we present the first checklist for spiders of Libya, based on published literature between 1881 and 2016-2017. Majority of the historic research was published in Italian, during the occupation period. The checklist include 353 species belongs to 174 genera and 37 families, among them 25 species and eight genera are new records for Libya. The specimens of the 25 new records were collected from the area extending from Tripoli to Msallata (Tripolitania, Northwest of Libya). This checklist will serve as a baseline information for further research on the biodiversity of spiders from this North African country.
