Aphonopelma iodius is a species of spider in the tarantula family Theraphosidae, found in United States (California, Nevada, Arizona and Utah).

[3] The formerly recognized A. melanium, A. angusi, and A. nevadanum were found to be in synonymy with, and were folded into, A. iodius.

[1] A. iodius lives in webbed burrows under the surface of desert areas of California, Nevada, and Utah.

They often obstruct the entrance to their burrows with a silken or silk and dirt plug to protect against heat and predators.

They transfer their sperm to sacs located in their pedipalps, then leave their burrows in search of a female.
