Subgenus uncertain

Chelostoma ventrale was formerly treated as a member of the subgenus Foveosmia (Michener, 2007; Ungricht et al., 2008). However, a recent phylogenetic analysis of the genus Chelostoma on a worldwide scale (Sedivy et al., 2008) revealed that this species does not belong to Foveosmia. Its phylogenetic position could not be resolved with certainty. Depending on the analysis, the species was either sister to the subgenus Gyrodromella or sister to the clade Gyrodromella+Chelostoma.
