Comments: We have examined the holotype and the paratype of this species, which are housed in the NHMW. In our opinion A. quinteroi is very similar to the members of the genus Achillidia Jeannel, 1962 . However we decided to investigate in more detail the identity and generic assignment of this taxon in a forthcoming study dealing with the members of Achillidia .
