We are greatly indebted to Mr. Charlie Lee (Miri) who discovered the Miocene outcrops south of Miri and collected most of the Miocene fossils described in this paper. Mr. Frank Wesselingh allowed us access to the collections of the National Museum of Natural History (RMNH, Leiden). We thank Mr. Yukito Kurihara and Mr. Tomoki Kase (Tokyo) for early sharing of their work on the Melongenidae.
