Orthetrum abbotti Calvert, 1892, a new Ethiopian representative in the Palaearctic fauna (Anisoptera: Libellulidae)

This Ethiopian sp. was found on the Arnon River (-- Wadi Mujib), Dead Sea Depression, Jordan, in the company of some other Ethiopian spp., e.g. Crocothemis sanguinolenta (Burnt.). It represents an addition to the list of spp. recorded from the palearetic area, and is a relict of one of the Pleistocene (pluvial) expansions of tropical African faunas towards the shores of the Mediterranean.
