Tienopeus

Tienopeus is a genus of small, ground-dwelling spiders belonging to the family Liocranidae. These spiders are found in various parts of the world, with a notable distribution across the Holarctic region, including Europe and North America. Tienopeus spiders are typically small, with a leg span of a few millimeters. They are often described as having a dark coloration, with variations in shades of brown and black. Their bodies are generally elongated, and they possess eight eyes arranged in two rows.

These spiders are nocturnal hunters and are usually found in leaf litter, under rocks, or in other sheltered, moist environments. They are opportunistic predators, feeding on small insects and other arthropods. Tienopeus spiders are not considered medically significant to humans, meaning their bite is not dangerous. Information on their specific reproductive behaviors and life cycles is somewhat limited compared to more extensively studied spider genera. The taxonomy of Tienopeus has seen some revisions over time, with species occasionally being reclassified into other genera or vice versa, reflecting ongoing research in arachnology. Their ecological role involves contributing to the control of small invertebrate populations within their habitats.
