Southern house spiders, crevice weavers, and the sexual dimorphism is dramatic enough to cause regular misidentification.
Females are dark, stout, and build tangled crevice webs, living for many years, which is unusual for a true spider of that size. Males are slender, long-legged, and light brown, and they are mistaken for recluses constantly by people who do not know the genus. They are not, and they are harmless.
Established across the southern United States and widely wild-collected, so prices are near zero. Husbandry is trivial: a container, an anchor point, small prey, occasional water. The genus is genuinely rewarding and almost completely ignored, which is why it costs nothing.
