EF22A6C280BD52B1A6FFAAB7830C9DFF.taxon	etymology	Etymology. The word marmer is Indonesian and means marble. It refers to the shell’s appearance reminiscent of marble and is used as noun in apposition.	en	Kadow, Laura, von Rintelen, Thomas, Iqram, Muhammad, Bichain, Jean-Michel, Haase, Martin (2025): Three new non-lacustrine species of the endemic freshwater gastropod genus Sulawesidrobia (Caenogastropoda, Truncatelloidea, Tateidae) from Sulawesi, Indonesia, with additional records of species from ancient Lake Poso.
