The present contribution deals with the members of the subfamily Lamiinae that are now known from Saudi Arabia. A total of 29 species or subspecies is recorded, and of these 7 are new to science: Dinocephalus heissi Holzschuh n. sp., Freapomecyna holzschuhi Teocchi n. sp., Pterolophia (Arabopraonetha Teocchi n. subgen. ) arabica Teocchi n. sp., Crossotus albicollis saudicola Teocchi n.ssp., Biobessa holzschuhi Teocchi n.sp., Sophronica talhouki Holzschuh n.sp. and Sophronica wittmeri Holzschuh n. sp. Six species are newly recorded from the Arabian Peninsula, and 10 are recorded for the first time from Saudi Arabia. Eunidia submarmorata Breuning, 1968, and E. naviauxi Villiers, 1977, are new synonyms of E. breuningae Villiers, 1951. The genus Paratitoceres Breuning, 1962, is synonymised with Titoceres Thomson, 1868, and the subgenus Arabosybrinus Breuning, 1948, with the genus Sophroniella Breuning, 1943, whichresults in the following new combinations: Titoceres arabicus (Breuning, 1962) n. comb., Sophroniella flavescens (Breuning, 1948) n. comb., and Sophroniella albosignata (Breuning, 1948) n. comb.
