The specific epithet comes from a combination of words, huei=big and tocatl=spider, in the Nahau language, indigenous to the region where the spider is found, and refers to the large size of this species. The name is to be treated as a noun in apposition.
Females can be distinguished from others by the large and posteriorly diamond-shaped median septum, the presence of epigynal pockets, and internally, the ducts are branched (Figs 77–78). Males unknown.
