In the present study, research materials consisting of approximately 1600 samples, which have been collected from almost the entire country since the 1960s, but mainly from the eastern anatolia region of turkey, were evaluated, 103 species and 2 subspecies in 4 genera, heriades, stenoheriades, hofferia and hoplitis, were recognized. of these, hoplitis (anthocopa) saxialis (zanden, 1994) is new for turkey as well the asian continent. hoplitis (hoplitis) manicata (morice, 1901), h. (h.) pici (friese, 1899) and h. (micreriades) mazzuccoi are new for the eastern anatolia region. erzurum is the easternmost distribution records of the first two species for that of h. mazzuccoi bitlis is the easternmost distribution record. many new distributional data were added for each species and the plant species they visited were included. concerning to zoogeographical view of the point, although present species could be included in various chorotypes they are mainly consantrated in the mediterranean basin. morover, about 60% of the anatolian species are associated with europe and about 40% are asian species, and those of 13 species live three of the continents, europe, asia and africa. with the present knowledge 18 species and subspecies could be accepted as anatolian endemics.
