D. golanica is characterized by a large, solid, bilobed adenodactyl positioned dorsally and to the right of the pointed penis papilla, while D. libanica has a large, solid, conical-shaped adenodactyl situated dorsally and to the right of the asymmetrical, finger-shaped penis papilla. These two species are clearly related to each other and to D. iranica (Livanov) from Iran and Turkey.</p>
