Euphrictus spinosus is a tarantula (family Theraphosidae), subfamily Selenogyrinae, first described by A.S. Hirst in 1908. It is only known from the male, and from the Dja River, Cameroon.
Only the male is known. Euphrictus spinosus is distinguished by having 7–8 spines on the tibia of the first leg; having a yellowish carapace and a brown abdomen with long bright yellow hairs; and a long tapering embolus with a slight twist in the middle. Its body is 15.5 mm long and it has a stridulating organ between its chelicera. It also lacks a clypeus.[1] [2]
