ABSTRACT: Taxonomic and faunistic results are presented for three genera of the tribe Pyraustini Meyrick, 1890 of the subfamily Pyraustinae Meyrick, 1890 based on material from the southern Arabian Peninsula. The new genus Dysgrammodes gen.n. is established and placed in the tribe Pyraustini Meyrick, 1890. It shares synapomorphies in the male genitalia with the genera Loxostege Hübner, 1825, Circobotys Butler, 1897, Anania Hübner, 1823, and Pagyda Walker, 1859. Character states differentiating the new genus from these genera are listed. The genus is monotypical, with Dysgrammodes rubrifascialis sp.n. as its type species. Taxonomic and faunistic updates are given for the genera Pyrausta Schrank, 1802 and Anania Hübner, 1823. Pyrausta flavicilialis sp.n. is newly described and placed close to the Afrotropical species Pyrausta centralis Maes, 2009 and Pyrausta grisealis Maes, 2009. Pyrausta phoenicealis Hübner, 1818 is reported for the first time in Saudi Arabia. The presence of the genus Anania Hübner, 1823 is reported as new to the entomofauna of the Arabian Peninsula. The records are attributed to the new species Anania interruptalis sp.n. The new species is recognized as unique among the Afrotropical species of the genus in wing maculation and placed close to Anania murcialis (Ragonot, 1895), Anania hortulata (Linnaeus, 1758) and Anania shanxiensis (Yang & Landry, 2019). The adults of each of the new species and of Pyruasta phoenicealis (Hübner, 1818), the male genitalia of Dysgrammodes rubrifascialis gen.n., sp.n. and of Pyrausta flavicilialis sp.n., the female genitalia of Dysgrammodes rubrifascialis gen.n., sp.n., Anania interruptalis sp.n. and of Pyruasta phoenicealis (Hübner, 1818), and the tympanal organs of Pyrausta flavicilialis sp.n. and of Anania interruptalis sp.n. are described and figured.
