Hebestatis theveneti
(Simon, 1891)
Thevenet's Trapdoor Spider
Hebestatis theveneti is a of cork-lid trapdoor spider in the Halonoproctidae. It is native to the United States and constructs burrows sealed with camouflaged, hinged trapdoors. The species is one of several trapdoor spiders maintained in research collections for study of arachnid and .

Identification
As a cork-lid trapdoor spider, Hebestatis theveneti possesses a hardened, disk-like (trapdoor) used to seal its burrow entrance. This distinguishes it from wafer-lid trapdoor spiders ( Euctenizidae), which use thinner, flexible lids. The Hebestatis is characterized by specific morphological features of the burrow architecture and genitalia, though precise diagnostic characters for H. theveneti require examination.

Habitat
Constructs burrows in soil, typically in undisturbed ground. The burrow is lined with silk and sealed with a camouflaged cork-like trapdoor constructed from soil, silk, and local debris.
Distribution
United States. Specific state-level distribution records are limited in available sources.
Behavior
Exhibits ambush from the burrow entrance. The spider remains beneath its trapdoor, detecting vibrations from passing prey through sensory structures, then rapidly emerges to capture prey. This sit-and-wait strategy minimizes exposure to and desiccation.
Ecological Role
of ground-dwelling . Its burrowing activity contributes to soil aeration and structure.
Human Relevance
Occasionally maintained in research and educational collections. Live specimens have been displayed at public outreach events, including the UC Davis Biodiversity Museum Day, to demonstrate trapdoor spider and sensory adaptations. Not considered medically significant.

Taxonomic Note
placement has shifted over time. NCBI lists this under Ctenizidae, but current consensus places Halonoproctidae as a distinct family. The Hebestatis was revised in recent taxonomic treatments of North American trapdoor spiders.
