Abstract
This study presents new data on the lacewing fauna of Saudi Arabia based on field work performed between 2014 and 2019. Sixty-one lacewing species from 37 genera and seven Neuroptera families were documented. Additionally, two species belonging to Dielocroce and Pseudomallada were identified only to genus level. Three of the identified species are new records to Saudi Arabia (Aspoeckiella gallagheri Holzel, 2004, Bankisus maculosus Holzel, 1983, and Nemoleon secundus Holzel, 2002). Another three species are new to the fauna of the Arabian Peninsula (Mantispa aphavacelte Aspock & Aspock, 1994, Ornoleon jean-neli Navas, 1936, and Stylascalaphus krueperi van der Weele, 1909). The first reports of eight species are provided after their original description from Saudi Arabia; namely, Creoleon ultimus Holzel, 983, Cueta amseli-Holzel, 1982, Cu. asirica Holzel, 1982, Distoleon asiricus Holzel, 1983, Geyriapaida Holzel, 1983, Neuroleon delicatus Holzel, 1983, N. virgineus Holzel, 1983 and Solter buettikeri Holzel, 1982 Zoogeographically, most lacewing species documented in the Arabian Peninsula are endemic (26.2%), followed by Afro-syroeremic (23.0%), Afrotropical (18.0%), and Afro-syro-iranoeremic (14.8%) species. Palaearctic species (4.9%) had the lowest contribution.
