All published records of 148 species of hoverflies from Morocco are reviewed and appropriate literature references, new locality records, and relevant comments are provided for each species. The list is supplemented with records from new field surveys. Two species, Eumerus obliquus (Fabricius, 1805) and Orthonevra brevicornis Loew, 1843 are recorded for the first time in Morocco. The new checklist comprises 150 nominal species from three subfamilies, 14 tribes, and 49 genera.

Eighteen species of Limoniidae and two species of Pediciidae are recorded for the first time in Morocco, of which 15 species are new to North Africa. An updated checklist of Moroccan short-palped craneflies (Limoniidae and Pediciidae) is appended, containing 73 species in 25 genera.

The genus Baeoura is represented in Morocco by two species, Baeoura ebenina Starý, 1981, and Baeoura staryi sp. n. The new species is described and illustrated, and a key to the West Palaearctic species of Baeoura is presented.

Till now only two species of the genus Trichocera, T. annulata and T. hiemalis, were recorded from north Africa. Herewith, we document seven species from Morocco, which extend distribution of the genus and the family to most southern localities of the western Palearctics in Africa (mountain ranges: the Rif, Middle Atlas and Beni Snassen). The following species were found: one new species in the nominate subgenus Trichocera (Trichocera) marocana, n. sp., and six of the subgenus Trichocera (Saltrichocera) (saltator, sardiniensis, pappi, annulata, regelationis, rufescens). The remarkably high share of the regelationis group of species in this southern fauna is discussed in view of tolerance of these species to warm climate.

The family Bolitophilidae is recorded for the first time from Morocco with one species Bolitophila (Bolitophila) saundersii (Curtis, 1836). Ten new species are added to the Moroccan fauna of Keroplatidae, known until now by only two species, raising the number of species currently known in Morocco to 12.
