Mueller (Fabaceae, Faboideae, Dalbergieae), is described, diagnosed and illustrated. The new species is morphologically similar to M. aeschynomenis, M. aurantia, M. cubana and M. didyma from which it differs in details of the terminalia and the host plant. Poiretia constitutes a previously unknown psyllid host. As its host, Mitrapsylla rupestris sp. nov. is probably endemic to rock habitats of the Espinhaço Range in eastern Brazil. These rock habitats display a high species diversity but are seriously threatened by human activities. More research on these habitats is urgently needed to design efficient conservation strategies.  aPsyllidae  aSternorrhyncha  aCiriacreminae  aDistribution  aPhytophagy  aPsilídeo  aSystematics1 aQUEIROZ, D.
