This species is listed as Data Deficient as the two known specimens are taxonomically uncertain and of unknown provenance. There is not enough information to assign this species to Extinct, which it was previously classified as. More work must be done on its taxonomy, and if validated, the actual native range of the species.

Geographic Range [top]

Range Description: This species is known only from three records, all postulated to have been from Okinawa Island (=Nansei-Shoto), Japan in the 19th century (Abe 2005). There are two specimens in the British Natural History Museum, and the whereabouts or existence of the third specimen is unknown. The two known specimens have been speculated to have possibly come from Southeast Asia and not Okinawa, or possibly to have been vagrants on Okinawa (Abe 2005). Therefore, this species is taxonomically uncertain and the existing specimens are of unknown provenance.
