C87887F0DB05FF80FE64F9050F82FC03.taxon	discussion	Comments This is the first record of the genus Sapygina from the Arabian Peninsula, specifically from Saudi Arabia family Sapygidae was previously represented in the region by a single species, Asmisapyga Gusenleitner, 1996, reported from the United Arab Emirates (Schmid-Egger 2010). The new species, S. saudica, is placed here in the subgenus Sapygella based on the presence of mandibular tooth that is distinctly larger than the preapical tooth, forming a right angle with it and clearly separated from the mandibular apex.	en	Gadallah, Neveen S., Soliman, Ahmed M., Al Dhafer, Hathal M.
