The distribution of phlebotomine sandflies in the principal ecological zones of Jordan.

A survey of the sandflies (Diptera: Psychodidae) of Jordan increased the number of species known from the country from three to thirteen. Composition of the phlebotomine fauna and the relative abundance of sandfly species differ among the six climatic zones, with a general distinction between the dry desert zones and the more humid Mediterranean zones. Species of Phlebotomus predominate in the former and Sergentomyia in the latter. Within the desert zone some species are restricted to the eastern desert and others to the Jordan Valley in the west.
