'anaptomorphidae' originates from New Latin, specifically the word 'Anaptomorphidae,' which is formed from 'Anaptomorphus' (a genus name) and the suffix '-idae' used for animal family names.

'Anaptomorphidae' was coined in scientific taxonomy in the 19th century to classify a group of extinct primates based on fossil evidence.

Initially, it referred specifically to a family of extinct primates, and this meaning has remained unchanged in modern scientific usage.
