Apomastus kristenae
Apomastus kristenae is a wafer-lid trapdoor spider described by Bond in 2004. It is one of two recognized species in the genus Apomastus, both endemic to restricted regions of southern California. Females are morphologically indistinguishable from the congeneric A. schlingeri, requiring molecular or geographic data for identification. The species occupies a habitat under severe pressure from urban development.
