This species was described in 2020 on the basis of subfossil remains, including two heads and a left elytron, that were recovered from cora samples that had been taken in the Te Roto Swamp on the island of ‘Atiu in the Cook Islands.

The size of this species could be reconstructed to have been about 0,78 cm in length; the heads are very dark brown to almost black, the elytron appears to have been dark brown colored. [1]
