GRAStodistus

GRAStodistus is a genus of small, terrestrial gastropod mollusks belonging to the family Streptaxidae. The genus was first described by the German zoologist Karl Jordan in 1877. GRAStodistus species are characterized by their small size, typically measuring less than 10 millimeters in length, and their distinctive shell morphology. The shell is usually low-spired, with a smooth or slightly sculptured surface, and a narrow aperture. The genus is found in various habitats, including grasslands, forests, and agricultural areas, and is known to feed on decaying plant material and other organic matter.

The genus GRAStodistus is distributed in the Palearctic region, with species found in Europe, Asia, and North Africa. The taxonomy of the genus is complex, with many species described in recent years. Some species are known to be host-specific, meaning they are only found on certain host plants, while others are more generalist feeders. The genus is of interest to taxonomists and ecologists due to its diversity and the role it plays in nutrient cycling in terrestrial ecosystems. However, little is known about the biology and ecology of GRAStodistus species, and further research is needed to better understand this fascinating group of gastropods.
