(Al-Quwayiyah, Al-Aflag, Al-Zulfi, and Riyadh), M. zulfiensis Soliman & Gadallah sp. nov. (Al-Zulfi and Riyadh), and M. khorimensis Soliman & Gadallah sp. nov. (Muzahimiyah and Riyadh). A key to Macroocula species with a ventral protuberance on the hind trochanter is provided. Key words: Bradynobaenidae, Apterogyninae, Macroocula, new species, Saudi Arabia 1. Introduction The genus Macroocula was described by Panfilov (1954) with the type species Apterogyna morawitzi Radoskowski, 1888. Members of the genus are widely distributed in Africa and Asia, mostly in North Africa, Arabia, and the Middle East (Pagliano, 2002, 2008, 2011; Lelej and Osten, 2004; Gadallah et al., 2014, 2015), and it currently includes 43 species (Pagliano, 2002, 2008, 2011; Gadallah et al., 2014, 2015). In the present paper, three new species of the genus Macroocula from Saudi Arabia are described and illustrated. Moreover, an illustrated key to Macroocula species with a ventral protuberance on the hind trochanter is provided. 2. Materials and methods Specimens were collected from Saudi Arabia (see Section 2.1 for further detailed indications). Sampling was done with light traps. Morphological terms are based on Pagliano (2002). Body sculpture terminology follows Harris (1979). Photographic images were made using a Canon G12 camera attached to an Optech triocular zoom stereomicroscope (LFTZ). Measurements were made with an ocular micrometer. Further image processing was done using the software Adobe Photoshop (v. 7.0 ME). The type specimens of the new species are deposited in three collections: King Saud University Museum of Arthropods, Plant Protection Department, College of Food and * Correspondence: 352 Agriculture Sciences, King Saud University, Riyadh, Saudi Arabia (KSMA); Efflatoun Bey Collection, Entomology Department, Faculty of Science, Cairo University, Giza, Egypt (CUE); and collection of G Pagliano (GPC), to be deposited in Museo Regionale di Scienze Naturali, Turin, Italy (MRSN). 2.1.
