Contribution to the Knowledge of the Afrotropical Spilomelinae (Lepidoptera, Crambidae): Three New Species and One Taxonomic Update in the Tribes Margaroniini Swinhoe & Cotes, 1889 and Agroterini Acloque, 1897, from Saudi Arabia
Taxonomic and faunistic results on three genera in the tribes Margaroniini Swinhoe & Cotes, 1889 and Agroterini Acloque, 1897—Omiodes Guinée, 1854, Patania Moore, 1888 and Notarcha Meyrick, 1884 are presented, based on material sampled in the Afrotropical part of the Arabian Peninsula, in the south-western province of Jizan, Saudi Arabia. Omiodesundularis sp.n., Pataniaorbiscularis sp.n. and Pataniarhomboidalis sp.n. are newly described. Of Omiodesundularis sp.n., the adults, male genitalia, and tympanal organs are described and figured. The female genitalia are unknown. The Afrotropical and Oriental species of the genus potentially related to the new species by external characters are reviewed. The differential character states distinguishing the new species from the closest related Omiodesindicata (Fabricius, 1775) are listed. The adults and male genitalia of Pataniaorbiscularis sp.n. are described and figured. The female genitalia are unknown. The species most closely related in the male genitalia is Pataniatchadalis (Leraut, 2005). The differential character states are listed. Of Pataniarhomboidalis sp.n., the adults, female genitalia, and tympanal organs are described and figured. The new species is externally closely related to Pataniatchadalis (Leraut, 2005), Pataniaharutai (Inoue, 1955), Pataniacrepuscularia Matsui & Naka, 2023, Pataniaaccipitralis (Walker, 1866) and Pataniafraterna (Moore, 1885) externally and in the female genitalia. The external and internal differential character states are listed. A determination key to the newly described Arabian species of the genus Patania Moore, 1888 and their closest relatives is given. The female genitalia of Notarchaviridalis Seizmair, 2021 attributed to the Notarchaquaternalis (Zeller, 1852) species complex, are described for the first time. The species is reported as new to the fauna of Saudi Arabia. A determination key based on the internal morphology of the species of the Notarchaquaternalis (Zeller, 1852) species complex is given.
