Aptostichus stephencolberti is a species of spider in the family Euctenizidae, named after the American satirist Stephen Colbert.

[3] Aptostichus stephencolberti is found on coastal dunes that extend from the Big Sur area to the San Francisco Peninsula at Point Lobos and Golden Gate.

The male holotype and the female paratype both have brownish yellow legs, carapace and chelicerae, while the abdomen is lighter with dusky stripes.

[1] The spider was named after Colbert after he reported on his television series The Colbert Report that Jason Bond, a professor of biology at East Carolina University, named a different species of spider Myrmekiaphila neilyoungi, after the Canadian rock star Neil Young.

"[5] The two men talked on the phone to decide which spider should be named after Colbert, but as there were 27 different species of spider available, Bond was left to make the final choice.
