Misumessus tamiami

Distinguished from other Misumessus species by its geographic restriction to southern Florida and the specific morphological characteristics documented in the original description. As a recently described species (2017), precise diagnostic features require reference to Edwards' original taxonomic work. The genus Misumessus is characterized by a somewhat flattened body and laterally extended legs that enable sideways movement.

Associated with the Tamiami Trail region of southern Florida, which traverses diverse subtropical habitats including cypress swamps, mangrove ecosystems, and coastal hammocks. The species likely occupies vegetation in these wetland and coastal environments where crab spiders typically ambush prey.

Southern Florida, USA, specifically the region associated with the Tamiami Trail (U.S. Route 41 between Tampa and Miami). Distribution records are limited to this subtropical coastal and wetland region of peninsular Florida.

As with other thomisid spiders, likely employs sit-and-wait ambush predation on vegetation, using crab-like leg positioning to seize prey.

Predator in subtropical wetland and coastal hammock ecosystems; contributes to arthropod population regulation through ambush predation on vegetation.

• Misumessus oblongusWidespread North American species in the same genus; M. tamiami is geographically restricted to southern Florida and differs in specific morphological features described by Edwards (2017).
• Other Thomisidae generaMisumessus species can be distinguished from other crab spider genera by genitalic morphology and body proportions; however, field identification to species level typically requires examination of diagnostic characters not visible without magnification.
