Genetic analysis#R suggested that this species, along with D. chrysorrheum, D. agile and D. everetti (and presumably D. vincens and D. annae, which are unsampled), may be closer to genus Prionochilus; placed in separate genus Pachyglossa by some authors#R#R, but here considered better to await findings of further analyses. Monotypic.
