A conspicuous entity of the aggregate of Ophrys sphegodes s.l. growing on the northern slopes of the volcanic massif of Etna is known since more than 20 years. Detailed studies show a singular combination of morphological characters, differentiating this population slightly from the type-species and other closely related taxa as O. exaltata subsp. exaltata and subsp. panormitana, O. arachnitiformis subsp. archipelagi (incl. O. mateolana, O. cilentana) and O. garganica. Because of these morphological differences and its singular ecology it is described as Ophrys sphegodes subsp. grassoana. Furthermore two new hybrids are presented, Ophrys exaltata Ophrys garganica from Niscemi (CL) and O. bertolonii subsp. explanata × O. holosericea subsp. apulica from the island of Favignana in West Sicily. While the parent areas of the first hybrid overlap largely from Calabria to Sicily, the parent areas of the second hybrid according current knowledge overlap very restrictivly only on the Egadian Islands.
