An updated and annotated checklist of the spiders (Arachnida: Araneae) of Iraq

An updated and annotated checklist of the spiders of Iraq, currently comprising 104 species in 75 genera and 29 families is presented, including six endemic and four subendemic species. Twenty-three records are considered misidentifications and therefore omitted from the checklist. Where possible, the misidentified records are attributed to other species based on their distribution and morphology; as a result of this, three species are recorded in Iraq for the first time: Dictis striatipes L. Koch, 1872 (Scytodidae), Hippasa deserticola Simon, 1889 (Lycosidae) and Latrodectus cinctus Blackwall, 1865 (Theridiidae). The history of studies and the geographical distribution of records are reviewed and discussed. The list is dominated by members of the families Gnaphosidae, Lycosidae, and Salticidae, comprising 15.4%, 13.5% and 10.6% of the total number of species, respectively.
