2 Materials and methods 
The material examined for the present work mainly originates from occasional collections 
carried out by professional entomologists. The flies were mostly double mounted (mi- 
cropinned on a block of white plastic or glued to a card slip), whereas a few others were pre- 
served in ethanol (ZSM). Because the specimens are small, usually less than 2 mm long, their 
study required the use of dissecting and compound microscopes, the latter having been used 
mainly for a perusal of the male genitalia structures of a few apparently enigmatic individuals 
of uncommon and even common species. 
In the text, species as well as the collecting localities of each species are listed in alphabeti- 
cal order. All of the eremic places cited in this paper are marked on maps with white numbers 
on black dots (Figs. 1-3). The maps are north-south oriented and distances from the sea coast 
of the localities marked by numbers are reported in detail throughout the text. All the diacrit- 
ical marks from Arabic are omitted in the text. Under the “Material examined” section of each 
species, significant supplementary or qualifying information is given in square brackets, and
