An updated checklist of the hoverflies including distribution and seasonal occurence data of known species in Nepal is presented. The list is based on all available published literature on taxonomy, biodiversity, ecology, and biological aspects of the syrphid fauna of Nepal up to ۲۰۲۳. A total of ۲۰۵ species from three subfamilies and ۶۳ genera are known to occur in Nepal. Among the three subfamilies, Eristalinae shares maximum species (۱۱۱ species, ۵۴%), followed by Syrphinae (۹۰ species, ۴۴%), and Microdontinae (four species, ۲%). is presented. Among these, ۴۸ (۲۳%) species are recorded in Nepal only. The distribution of known hoverfly species in the country is not uniform, with the Bagmati (۸۲ species) and Koshi (۷۵ species) provinces having the greatest number of species, while the Madhesh (four species) and Lumbini (one species) provinces having the lowest records. The highest number of species are recorded in May (۵۱ species), followed by July (۵۰ species) and June (۴۸ species). Winter season records are relatively low, and distribution data are still incomplete for some sites. Based on the present review, comprehensive and systematic sampling across the entire country is necessary for further exploration of Nepal's hoverfly fauna.
