Syrphid flies frequently called as Hover flies established as effectual pollinators of plants. They exhibit a substantial morphological assortment within the family. To comprehend their diversity, a few isolated studies have so far been carried out in eastern and western Himalayas. This current paper includes a complete distributional scenario of Syrphidae recorded from India, an updated checklist consisting of altogether 69 Genera and 355 species along with their distributional array within the country have been reported here, however some species which were reported in earlier literature but due to lack of proper literature documentation they has not been documented in this current and updated checklist, namely, Syrphus agraensis Nayar & Nayar 1965, Scavea lunata (Wiedemann, 1830).In this present investigation the latest synonimisation and sub genus status as well the current nomenclature pattern has been taken into account. This study may find future applications in monitoring the conservational factors that may affect their distribution and/or diversity.
