Species
There are currently 3 recognized species in this genus:
- Monacoa grimaldii (Zugmayer, 1911) (Mirrorbelly)
- Monacoa griseus J. Y. Poulsen, Sado, C. Hahn, Byrkjedal, Moku & Miya, 2016 (Grey mirrorbelly) [1]
- Monacoa niger J. Y. Poulsen, Sado, C. Hahn, Byrkjedal, Moku & Miya, 2016 (Black mirrorbelly) [1]
Until 2016, it was believed there was a single species of Monacoa, but in 2016 it was determined that they're actually 3 distinct species. The griseus and niger are distinct from the grimaldii because of their differences in pigmentation. An examination of their complete mitochondrial genomes further suggests the species are distinct.
