Abstract
Two new Indonesian taxa are proposed in Onthophagus Latreille, 1802, illustrating the composite faunal spectrum of the Lesser Sundas (Indonesia): O. montishannoniae, a new species from Flores, and O. accedens nusatenggaricus, a new subspecies from Lombok and Flores. O. accedens Lansberge, 1883 is, with O. dux Sharp, 1875, placed in what is here defined as the dux subgroup within the subgenus Parascatonomus Paulian, 1932. The three included species‐group taxa are keyed, their status is discussed, and new records are given. The position of O. montishannoniae seems taxonomically and geographically isolated: this species has no known close relatives in the region, neither in the Lesser Sundas, nor anywhere else in Wallacea.

We are indebted to our colleague A.L. van Berge Henegouwen (Museon, The Hague, The Netherlands) for submitting his Flores material to us; the Bornean material of O. dux briefly mentioned was largely collected by A. Kirk‐Spriggs (at the time Cardiff, UK), A.J. Davis (at the time Cambridge, UK), and I. Hanski (Helsinki, Finland). Some specimens of O. a. accedens recorded in the text were found in the Zoological Museum of the University of Amsterdam.
Field support came from S. Kahono (Bogor, Indonesia), and R. de Vries (Leiden, The Netherlands). A.L. van Berge Henegouwen was assisted by our old friend S. Pariwono (Bogor, Indonesia), since deceased. Thanks are also due to the Indonesian Institute of Science (LIPI, Jakarta) for supporting our field work.
