Species

The species composition of Helicopsis was largely reviewed after revisions with methods of molecular taxonomy, many of the previously recognized species were shown to be conspecific and many other to be not related with true Helicopsis.[5][2] After these revisions only 9 or 10 species can be placed into Helicopsis:[5][2]
