About Kukulcania arizonica (Chamberlin & Ivie, 1935)
Kukulcania arizonica, commonly called the Arizona black hole spider, is a species of spider in the family Filistatidae. As both its scientific and common names suggest, this spider is found in Arizona, and it also occurs in the neighboring US states of New Mexico, Nevada, and California. This is a black spider with a velvety texture. It builds a silken tube inside a crevice, often on the wall of a building, with silken threads that radiate out from the entrance of the tube. Females are around 13 mm long when excluding legs, and can live for several years. Males differ noticeably from females, with distinctly longer legs and a thinner body.
