It is similar to B. cathcartii but can easily be distinguished by a lamina with a dark central spot and a densely pilose upper surface in combination with a short dorsal capsule wing. A phylogenetic analysis based on three chloroplast regions placed the new species together with other continental species in section Platycentrum. Both morphology and molecular data suggest the new species as a member of the section Platycentrum. %M doi:10.6165/tai.2022.67.165
