Biopsoilla

Biopsoilla is a genus of small, terrestrial gastropod mollusks belonging to the family Hygromiidae. The genus was first described by German malacologist Karl Wilhelm Verhoeff in 1938. Biopsoilla species are characterized by their small size, typically measuring less than 10 millimeters in length, and their smooth, glossy shells. They are found in various habitats, including forests, grasslands, and agricultural areas, and are known to feed on decaying plant material and fungi.

The genus Biopsoilla is currently known to include two species: Biopsoilla bicolor and Biopsoilla hirtella. Biopsoilla bicolor is found in Europe and North Africa, while Biopsoilla hirtella is native to the Mediterranean region. Both species are considered to be of minor ecological importance, as they play a limited role in the decomposition of organic matter in their respective habitats.

Biopsoilla species are typically nocturnal and are known to be active during the cooler parts of the day. They are hermaphroditic, meaning that each individual possesses both male and female reproductive organs. However, they do not self-fertilize and require a mate to reproduce. The eggs are laid in a gelatinous mass, which is deposited on the substrate in a sheltered location.

Biopsoilla species are not considered to be of significant conservation concern, as they are widely distributed and have a relatively large population size. However, like all gastropod mollusks, they are susceptible to environmental degradation and habitat loss, which can impact their populations. Further research is needed to better understand the ecology and conservation status of Biopsoilla species.
