Compared to other primates from the time, Anaptomorphus is rather advanced in dentition, with the dental formula being 2,1,2,32,1,2,3 × 2 = 32.^[1]

Anaptomorphus is placed within Omomyidae, related to (and often sister clade of) Tarsiers. A. homonculus , a species formerly assigned to Anaptomorphus, has been moved to the related genus Tetonius.^[2]^[3]
