Aptostichus bonoi

[1] The species was found in Joshua Tree National Park,[2] California, and described by the Auburn University professor Jason Bond in 2012.

The two species are easily distinguished from one another due by spines on the retrolateral surface I, which A. serrano lacks.

The species is known only from an area of Joshua Tree National Park called Covington Flat, which is the type locality.

The available data is very limited, but it is assumed that males disperse to look for females from late fall until early winter.

[5] Due to the very limited range of the species and its scarceness in collections, it is probable that Bono's Joshua Tree trapdoor spider is endangered in terms of its conservation status.
