The presence of the genus Pyrausta Schrank, 1802 (Lepidoptera, Crambidae, Pyraustinae) on the Arabian Peninsula – faunistic and taxonomic notes with description of a new species
Author(s): Michael Seizmair
Abstract: The species of the genus Pyrausta Schrank, 1802 reported till date from the Arabian Peninsula are listed and reviewed. Till date, two described species have been known from the Arabian Peninsula – Pyrausta arabica Butler, 1884 and Pyrausta phoenicealis (Hübner, 1818). The external diagnostic character states, the global distributions and the local distributions of these species on the Arabian Peninsula are commented on. On the basis of material collected by the author in Dhofar, the south-western province of the Sultanate of Oman, a third species of the genus is added to the entomofauna of the Arabian Peninsula, which differs significantly in external character states from congeners with related wing patterns. These differences result in the description of a species new to science, Pyrausta postmediofusalis sp.nov. The closest related congeners are Pyrausta mahensis Fletcher, 1910, Pyrausta fulvilinealis, Hampson, 1913, Pyrausta amboinalis Pagenstecher, 1884, Pyrausta phragmatidalis Hampson, 1908 and Pyrausta subflavalis Warren, 1892. The new species is differentiated from these comparative species in the combination of the following external character states: forewing and hindwing grounds concolorous, width, shape and connectedness of the antemedial, postmedial and subterminal lines in the forewing and absence of lines in the hindwing. In internal character states the new species is unique in the projected basal costa of the valva, the sclerotizations in the basal and postbasal uncus, in the shape of the juxta and in the shape of the cornutus.
