Taxonomic and faunistic results on six genera of the Pyraustinae (Lepidoptera, Crambidae) are presented on the basis of material collected in SW Saudi Arabia (Hejaz, Asir and Fayfa mountains) and in Dhofar, the south-western province of Oman. A new species of the genus Psammotis Hübner, 1825, Psammotis rubrilinearis sp. nov. is described. The adults, the male and female genitalia and the tympanal organs are described and figured. The new species is placed closed to Psammotis pulveralis (Hübner, 1796), Psammotis roseus Maes, 2014 and Psammotis rubrivena (Warren, 1892) on the basis of shared character states in the male and female genitalia. The differential character states in wing maculation and morphology are listed. The presence of the genus Psammotis Hübner, 1825 is reported as new to the entomofauna of the Arabian Peninsula. New distributional records are given for four described species of the subfamily. The presence of Achyra nudalis (Hübner, 1796) in Saudi-Arabia is re-confirmed. Palepicorsia ustrinalis (Christoph, 1877) and Uresiphita gilvata (Fabricius, 1794) are reported as new for Oman. Pioneabathra olesialis (Walker, 1859) is reported as new for Saudi-Arabia. The current taxonomic status of the Arabian populations of Pioneabathra olesialis (Walker, 1859) is reconfirmed by means of DNA-Barcoding. The male and female genitalia of Achyra nudalis (Hübner, 1796) and Pioneabathra olesialis (Walker, 1859) and the male genitalia of Palepicorsia ustrinalis (Christoph, 1877) are figured.
