Megalobulimus amandus is a species of air-breathing land snail, a terrestrial gastropod mollusc in the family Strophocheilidae. The species is endemic to Brazil and was described based on shells collected in a Caatinga area in the state of Bahia.
The species was described in 2012 from shells deposited in the collection of the Museum of Zoology of the University of São Paulo. The specific name amandus derives from the Tupi language words amanda or amana, which mean "rain" or “related to rain,” referring to the shape of the shell, resembling a drop of water.[1]
According to the original species description, M. amandus appears to belong to the “Megalobulimus oblongus complex.”[1] This so‑called complex, as originally defined in 1998, encompasses species with a periostracum that peels off while the animal is still alive (desciduous), a reddish peristome, a shell surface with strong longitudinal sculpture, and a protoconch whose surface also features longitudinal sculpture composed of pronounced undulations and cords.[2]
