Remarks. The label data of the two newly examined specimens revealed their identity has been constantly changed by the late Gaston Ruter (1898–1979). Ruter initially plan to introduce a new genus for them in 1976, and he later realized the two belonging to the genus Platysodes . According to the letter he sent to Gordon M. Nishida (former collections manager of BPBM) in 1979, he finally identified them as P. jansoni with the help from the museum in Leiden (James H. Boone, personal communication, October 2016).
