Antrodiaetus hageni
Antrodiaetus hageni is a species of folding-door spider in the family Antrodiaetidae, first described by Chamberlin in 1917. It belongs to the infraorder Mygalomorphae, a group of spiders characterized by downward-directed fangs and relatively primitive body plans. The species is known from the United States, though detailed natural history information remains limited in published sources.
Antrodiaetus lincolnianus
Lincoln's folding-door spider
Antrodiaetus lincolnianus is a species of folding-door spider in the family Antrodiaetidae, originally described as Brachybothrium lincolnianum by Worley in 1928. As a mygalomorph spider, it constructs a burrow sealed with a hinged, silken door that it uses for protection and ambush predation. The species is endemic to the United States. Like other members of the Antrodiaetus unicolor species complex, it has been subject to recent taxonomic revision using molecular methods due to cryptic morphological similarity with closely related species.
Antrodiaetus montanus
Mountain Folding-Door Spider
Antrodiaetus montanus is a mygalomorph spider in the family Antrodiaetidae, commonly known as folding-door spiders. The species constructs silk-lined burrows with hinged, trapdoor-like closures made of silk and soil. It is native to mountainous regions of the western United States. Like other antrodiaetids, it exhibits fossorial behavior and is rarely observed above ground except during dispersal events.
Antrodiaetus pugnax
folding-door spider
Antrodiaetus pugnax is a species of folding-door spider in the family Antrodiaetidae. It belongs to the infraorder Mygalomorphae, one of the three main lineages of spiders. The species was originally described as Brachybothrium pugnax by Chamberlin in 1917. Like other members of its genus, it constructs a burrow with a folding door, distinguishing it from trapdoor spiders that use a hinged door.
