Three New Species of the Genus <i>Autocharis</i> Swinhoe, 1854 (Lepidoptera: Crambidae, Odontiinae) from the Southern Arabian Peninsula

Abstract

New taxonomic results on the genus Autocharis Swinhoe, 1854 (Lepeidoptera: Crambidae, Odontiinae) are presented on the basis of a sample of 11 specimens collected by the author in southwestern Oman between 2017-2019. The attribution of the material to the genus Autocharis Swinhoe, 1854 and the exclusion of other genera close to Autocharis Swinhoe, 1854 was done on the basis of differential features in the forewing venation. Examination of the wing pattern and the genitalia resulted in the attribution of one part of the sample (10 specimens) to the Autocharis seyrigalis (Marion & Viette, 1956) species complex and of the other part (1 specimen) to the Autocharis fessalis (Swinhoe, 1886) complex. Morphpmetric analysis of the sample and comparison with type material of the respective species groups revealed significant differences between the specimens of the sample and the representants of the two species groups. These differences result in the description of three new species: Autocharis trisignalis Seizmair, sp.nov. Autocharis renalis Seizmair, sp.nov. belonging to the Autocharis seyrigalis (Marion & Viette, 1956) complex and Autocharis arrondalis Seizmair, sp.nov. belonging to the Autocharis fessalis (Swinhoe, 1886) complex. Furthermore, the presence of the Autocharis seyrigalis (Marion & Viette, 1956) complex is reported as new to the entomofauna of the Arabian Peninsula. Up to now, records of the Autocharis seyrigalis (Marion & Viette, 1956) complex have been restricted to South Africa and the Malagasy region.
