Ethobunus is a Neotropical genus of zalmoxid harvestmen with a low ocularium lacking a median spine.
Characters (Goodnight & Goodnight 1983, as Dapessus): Small to medium sized animals, cephalothorax somewhat narrower than abdomen. Eye tubercle without dorsal spine, slightly removed from anterior margin of cephalothorax. Dorsal areas five in number, first area without median line, dorsal borders of areas parallel . Free tergites smooth, spiracle usually concealed by portion of coxa IV. Tarsal segments 3-6 or more than 6-5-6 . Distitarsus of first tarsus with two segments, second with three . Metatarsi of legs without astraguli or calcanei . Tarsal claws of legs III and IV double, smooth. Penis a chitinous shaft, usually somewhat inflated at distal portion, enclosing softer structures. Secondary sexual characters variable but usually consisting of enlarged basal segments of tarsus III and varying leg lengths .
