New Ireland present, eastern part present, mainland present
Malesia: New Guinea (mainland, eastern part), New Ireland.
On the New Guinean mainland the species is distinctive in the genus in its combination of long, articulate pedicel and small bracts. The specimens from New Ireland have a very short or obsolete pedicel, but otherwise agree with Sogerianthe sogerensis.
