New findings report the first confirmed distribution of Merodon nigroalatus in India, indicating possible associations with Hippeastrum species.
This study presents the first confirmed record of Merodon Meigen, 1803 from India and the Oriental region, based on adult specimens of Merodon nigroalatus Vujić et al., 2023, collected from the Western Himalaya and Lower Gangetic Plains. The findings indicate a range extension of this genus, highlighting a previously undocumented distribution and a likely association with Hippeastrum spp. (Amaryllidaceae). A brief diagnosis, representative images of both sexes, including male genitalia, and a distribution map of the species in India are provided to facilitate its prompt identification and future records.
