Female cephalothorax length ranges from 3.08–3.78 and total length form 6.26–7.42 (n = 3). Natural history. Pimoa tehama n. sp. is only known from the type series, and beyond the collection of these four individuals it has not been observed in nature. All three individuals were found in mixed conifer forest at around 1,350 meters elevation. The female from Blackjack Spring was found in a small horizontal sheet web typical of pimoids in a deep cut creek, and the male was found wandering in the same creek two years later. The other female was found hiding under bark, and may have been associated with a web that was destroyed when the bark was moved.
