From editor or global species database

Editor's comment Helicostyla and Cochlostyla were described in the same work. Martens (1860) was the first to give preference to Cochlostyla by treating Helicostyla as a subgenus of Cochlostyla. To this day it is uncertain if both genera are separate units or not. Even if they were, it remains uncertain, which species should be placed in which genus. Until this problem is solved, species should preferably placed in Cochlostyla. [details]
