New data about Moroccan soldier flies (Stratiomyidae) are presented in the present study that discusses 15 species. Six species are recorded as new to the fauna of Morocco, four of which, Oxycera analis Wiedemann in Meigen, 1822, O. flava (Lindner, 1938), O. marginata Loew, 18959, and Chorisops tibialis (Meigen, 1820) are new records for North Africa. Oxycera morrisii (Curtis, 1833) is recorded for the first time in Morocco. Hermetia illucens (Linnaeus, 1758) was recently reported based on a personal communication without details but is now also formally added. It adds a new subfamily to the Moroccan fauna, the Hermetiinae. Notes on taxonomy, distribution and biology of the species are added. The male of O. flava is described and illustrated.
