Cyclocosmia, a genus belonging to the mygalomorph trapdoor species of the Halonoproctidae family, has ten species as per the April 2019 records. They were initially a member of the Ctenizidae until 2018, after which the family underwent a split.
Size: The females of this genus are bigger than males. Cyclocosmia ricketti species are 1.1 inches (28 mm) long, having 0.63 inches (16 mm) disk diameter.
Color: Most spiders of this genus have a brown body with the patterns varying from one species to another.
Other Characteristic Features: Their abdomen having a spiny projection is truncated abruptly, ending in hardened disks, strengthened by ribs and grooves.
They are small and round with a pale coloration.
Information about the spiderlings remains unavailable, though, like most other species, they too go on their own after maturation.
Being a genus of trapdoor spiders, they do not spin webs like most other species. Instead, they have a trapdoor-like structure on top of their burrow having a depth of 2.8 to 5.9 inches (7 to 15 cm). There is also a silk lining only at the bottom of the burrow.
Most spiders of this genus are known to have a low level of toxicity, not causing harm to humans.
| Distribution | United States and parts of Asia (China, Thailand, Laos, and Vietnam) |
| Habitat | Mostly live underground in warm places but may even build their burrows |
| Predators | Wasps and scorpions |
| Diet | Cricket, moth, beetles, and grasshopper |
| Lifespan | Approximately 5 – 10 years |
