The genus name refers to the spine-like (acanthoid) structures on the body. Accurate identification to level requires microscopic examination and comparison with original descriptions.
Distribution
Records exist from Australia, the region where Girault described many chalcidoid . Specific distribution details are sparse due to limited collecting and identification effort for this .

Taxonomic History
A.A. Girault described Acaenacis in 1917 based on Australian material. Girault was a prolific but controversial taxonomist who named thousands of chalcidoid and , many based on limited material. The genus has received little subsequent taxonomic attention, and its current circumscription may require revision.
Nomenclature
The name is derived from Greek 'akantha' (thorn/spine) with the suffix '-acis', referring to the spiny body surface.
