This study presents a brief review of the genus Stegana Meigen (Diptera: Drosophilidae: Steganinae) from India, emphasizing its diversity and ecological significance within the Dipteran fauna. Through detailed morphological examination, we describe here a new species, Stegana (Oxyphortica) minuta Kandpal, Sati & Fartyal sp. nov., from Ayarpatta, Nainital, Uttarakhand. The new species is described, and diagnostic characters are illustrated, along with a key to all six species of Stegana known from India. The discovery of a new species further enriches knowledge of the region's insect fauna. Based on a synthesis of existing records, India is estimated to harbor approximately 363 drosophilid species across 27 genera. This remarkable diversity reinforces the Indian subcontinent's status as a crucial center for drosophilid biodiversity.
