Nine species of dictyostelid cellular slime molds were obtained from Dhufar Province, Oman. One of them is a new species, Dictyostelium arabicum, which is described and illustrated, and the others are known species and new to Oman. Of nine dictyostelids, five are subtropical and/or tropical species, namely. D. lavandulum, D. macrocephalum, D. magnum, D. monochasioides and D. polycephalum, and other two, D. purpureum and P. violaceum, are cosmopolitan species, and the other one, D. lacteum, is rare in subtropical and tropical regions. D. lacteum is illustrated and briefly described. In addition, many isolates not belonging to the above nine species were obtained and grouped in three species complex as follows : The Acytostelium leptosomum complex, the Dictyostelium mucoroides complex and the Polysphondylium pallidum complex. All the species are enumerated together with the complex, and some of them are discussed in terms of their morphological features and ecological distributions.
