'argasidae' originates from New Latin, formed from the genus name 'Argas' plus the taxonomic family suffix '-idae' (used to form animal family names).

'argasidae' was coined in modern zoological nomenclature (New Latin/19th century usage) by combining the generic name 'Argas' (used for a group of soft ticks) with the standardized suffix '-idae', and it entered scientific English as the name of the family.

Initially it referred specifically to taxa related to the genus 'Argas' in taxonomic usage; over time it became established as the formal name for the entire family of soft ticks (the modern meaning).
