Pisaurina brevipes
Straight-banded Nursery Web Spider
Pisaurina brevipes is a nursery web spider found in the eastern United States and Canada. It closely resembles the more common Pisaurina mira but is distinguished by proportionally shorter legs and straighter edges on the abdominal band. Females measure 11–13 mm in body length, males approximately 10.8 mm. The species favors grasslands, bogs, and swamps, though detailed natural history remains poorly documented.
Tinus
nursery web spider
Tinus is a genus of nursery web spiders in the family Pisauridae, established by F. O. Pickard-Cambridge in 1901. The genus includes small-bodied species that are notably smaller than most other pisaurid genera such as Dolomedes and Pisaurina. Tinus peregrinus is the best-documented species, known from the southwestern United States and northern Mexico. Members of this genus prefer vertical surfaces and are often found near water edges.
Tinus peregrinus
nursery web spider
Tinus peregrinus is a small nursery web spider in the family Pisauridae, notable for being the smallest member of its family in North America. Adults reach only about 10 mm in body length, with males slightly smaller than females. The species occurs across the southwestern United States and northern Mexico, where it inhabits riparian edges and human structures near water. Unlike larger fishing spiders and nursery web spiders, T. peregrinus is rarely encountered due to its diminutive size and cryptic habits.
