''Andalucia'' is a genus of jakobids.

Classification

The morphology of ''Andalucia'' broadly resembles that of other jakobids. Molecular data has not always been conclusive, but recent phylogenomic analyses indicate that ''Andalucia'' is a sister group to the other jakobids, in other words more closely related to them than to the
