Rhinorhipus is a
genus of beetles that contains a single species, Rhinorhipus tamborinensis from southern
Queensland, Australia.[1] It is the sole member of the family Rhinorhipidae and superfamily Rhinorhipoidea. It is an isolated lineage not closely related to any other living beetle, estimated to have split from other beetles at least 200 million years ago, with studies either considering them the earliest diverging member of
Elateriformia,[2] or a basal lineage within
Polyphaga.[3] They exhibit feigning death (
thanatosis) when disturbed. Their ecology is poorly known. It is likely that they are
fossorial based on their morphology.[4]
