Oreoneta
A genus of dwarf spiders (family Linyphiidae) established in 1894, comprising approximately 30 species distributed across cold-temperate and Arctic regions of the Northern Hemisphere. Most species inhabit high-latitude or high-altitude environments. The genus was revised extensively by Saaristo & Marusik in 2004, resulting in numerous new species descriptions.

Leaflitter Crab Spiders
Ozyptila is a genus of small crab spiders (Thomisidae) established by Eugène Simon in 1864. The genus comprises approximately 103 species distributed across Africa, Europe, North America, and Asia. Members are ground-dwelling spiders with a distinctive pear-shaped, elevated carapace and short, spiny forelegs. They are frequently mistaken for the related genus Xysticus but are generally smaller in body size.
Ozyptila conspurcata
Ozyptila conspurcata is a crab spider in the family Thomisidae, first described by Thorell in 1877. The species is recorded from Canada and the United States, with confirmed observations in Alberta. As a member of the genus Ozyptila, it belongs to a group of small, ground-dwelling crab spiders that ambush prey rather than constructing webs.
Pagasa nigripes
Pagasa nigripes is a small, dark damsel bug in the family Nabidae. Like other members of its genus, it is ground-dwelling and has a compact, beetle-like appearance. The species exhibits wing dimorphism, with individuals either fully winged or having reduced, non-functional wing pads. As a nabid, it is a predatory true bug with raptorial front legs adapted for capturing prey.
