Type locality. “supra truncos arborum in montibus insulae Negros, Philippinarum”.

Remarks. We have not examined the type specimens, but based on the descriptions it became obvious that the differences are so slight (only differing in colour of peristome), that the subspecies of Bartsch (1916) cannot be maintained.
