The speartooth shark Glyphis glyphis is found in Australia and Papua New Guinea, and it was so far never reported beyond this extension range. The present paper provides the first register of this species outside this known distribution. We collected one of G. glyphis in 2018 at Digul River, Mapi district, Papua province, Indonesia. This record represents the first known occurrence of this species in Indonesia, and an extension of its original geographical distribution in about 250 km north. Registers of new localities for G. glyphis were based on photographs.
