Abstract A new genus and species of Stereomerini, Cheleion malayanum gen. n. and sp. n., are described based on a single specimen from the Malacca peninsula in Malaysia. It is the fi rst stereomerine found on

A key to genera of Stereomerini and a phylogenetic estimate of the stereomerines using 24 species representing 7 tribes of Aphodiinae based on 53 morphological characters. Th e phylogenetic analysis places the new species within the tribe Stereomerini as a sister to the monophyletic group including Adebrattia, Austaloxenella, Bruneixenus, Pseudostereomera and Stereomera. A survey is given of the various taxa of Aphodiinae that are termite and/or ant inquilines, or have been presumed to be so based on morphology, and their phylogeny is discussed.
