Tetonius homunculus had a dental formula of 2:1:3:3 on both the upper and lower jaw (Fleagle, 1988). The upper molars of this species have a postprotocingulum (Martin, 1990). This species has a short snout (Fleagle, 1988). The eyes of this species are large and are of the size of cheirogaleids suggesting this species was nocturnal (Fleagle, 1988). This species had a true lateral sulcus (Radinsky, 1970; cited in Martin, 1990). The cranial capacity of this species was 1.5 cc (Conroy, 1990). This species had a relatively small frontal lobe and olfactory bulbs as compared to other strepsirrhines (Conroy, 1990). This species had an average body mass of about 290 grams (Fleagle, 1988).
Tetonius homunculus was found in North America, more specifically in the state of Wyoming and occurred during the early Eocene (Fleagle, 1988).
Based on dental morphology, this species probably had a insectivorous diet (Fleagle, 1988).
