Tmarus
Octopus Spiders
Tmarus is a large genus of crab spiders (family Thomisidae) established by Eugène Simon in 1875, with more than 230 described species distributed across all continents except Antarctica. These small to moderate-sized spiders (3.7–7.3 mm body length) are characterized by cryptic bark-like coloration and ambush predatory behavior. The genus exhibits sexual dimorphism, with females typically larger than males.
