Etymology The epithet ‘ morehensis ’ refers to the name of Moreh, a small town located within the Tengnoupal district, which is significant as part of the species’ habitat. By incorporating ‘ morehensis ’ into its scientific name, this earthworm species pays homage to the geographical region where it was first discovered, highlighting the importance of local ecosystems in biodiversity conservation efforts.
