Remarks.

Molecular studies ( Breure and Romero 2012, Breure unpublished data) strongly suggest that this genus, treated with several subgenera by Breure (1979), is polyphyletic and only the nominate taxon is grouping with Megaspira . However, further studies are needed as taxon sampling has been relatively low until now.
