Comments & ID Thoughts

Spider was the size of a U.S. quarter. It moved at a slow crawl crossing asphalt road. Trapdoor spider?

Whoa, he’s a radiant fellow! I’m not well acquainted with Mygalomorphae … but this looks to me like it might be a California Trapdoor Spider (Bothriocyrtum californicum). They’re typically a lot darker than this, black even. I have to wonder if he’s freshly molted. Maybe someone will be along eventually who knows them better than me with more insight.

The genus is Myrmekiaphila, family Euctenizidae. The funny pinched-looking metatarsus on leg I is diagnostic.
