Bunodes is characterized by a vaulted carapace with radiated hump-like ridges.[7] Within the 10-segmented opisthosoma, the first opisthosomal tergite is greatly reduced and always covered by the posterior region of preceding carapace, while the second tergite is significantly well-developed.[7] the last 3 opisthosomal segments specialized into a narrow postabdomen and lacking tergopleurae (lateral extension of tergites).[7] Tubercles of various sizes covering most of the dorsal surface of both carapace and tergites.[7] Similar to Limuloides, Bunodes was once thought to have lateral eyes on the second pair of radiated ridges of its carapace,[7] but later investigation did not find any evidence of it.[8]
