The tribe Adelungiini Baker, with Platyproctus agraphopteron Bergevin, 1932, P. melichari (Kusnezov, 1929), and P. emir sp. nov., collected on Calligonum crinitum Boiss. arabicum Sosk., is recorded for the first time from the United Arab Emirates. Symphypyga omani Kameswara Rao et Ramakrishnan, 1983 and Assiuta camena Linnavuori, 1969 are transferred to the genus Platyproctus Lindberg, 1925 based on male genitalia structure, with new combinations proposed – Platyproctus omani (Kameswara Rao et Ramakrishnan, 1983), comb. nov. and P. camena (Linnavuori, 1969), comb. nov. Platyproctus emir sp. nov. is closely related to P. camena and P. omani in general male genitalia structure, but well differs by the aedeagus with denticles on dorsal surface of the shaft and wider pygofer lobes. The genus Assiuta Linnavuori 1969 is treated as monotypic Canarian endemic, monophage on Traganum moquini Webb ex Moq. Assiuta salina is close to Emelyanogramma proxima (Dlabola, 1960) by strongly dentate ventral margin of aedeagal shaft. The lectotype is designated for Symphypyga melichari Kusnezov, 1929. Platyproctus flavidus Dubovsky, 1966 is placed in synonymy under P. marmoratus (Horváth, 1894) while P. maculatus (Pruthi, 1930) and Symphypyga melichari fuscopunctata Kusnezov, 1929 are placed in synonymy under P. malichari (Kusnezov, 1929). Illustrations of male genitalia structure for E. proxima and the photos of external views for A. salina and P. camena are given for the first time.
