Extremely rare and elusive species. Minor peck mark at the spire area. This specimens are from the north of Borneo. All these specimens were collected at least 30 years ago and during that time, the late Mr. Chua Kim Swee was heavily involved in the logging industry and thus, manage to obtain these specimens. There is not many and I doubt they will be easily obtained as that part of Sabah is heavily logged and converted to farming land. Hopefully they still exist but for now, apart from these specimens there is only a few in the world! The paper is published in The Festivus, August 2018.
