Megalobulimus is a genus of air-breathing land snail, a terrestrial gastropod mollusk in the subfamily Megalobuliminae within the family Strophocheilidae (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).
Megalobulimus is the type genus of the subfamily Megalobuliminae.
Description
(Original description) The jaw and radula of the following species differ so considerably from those of the typical Borus oblongus Müll. that I considered establishing a new subgenus, Megalobulimus, into which the giants of the Bulimidae would be classified. These could be characterized by the absence of strong transverse ribs on the jaw, a finely granular shell, reddish-brown upper whorls, a white band accompanying the suture, and a white aperture.
Distribution
These species are primarily found throughout South America—especially in the Andean Amazon and eastern Brazil. Some species are widespread across the continent, while others are locally restricted.
Habitat
Habitats include humid tropical forests, grasslands, and often forest litter and soil. Some species have an affinity for limestone soils and may be found in or near caves.
