New conclusions on the distribution of Onyxacalles portusveneris (Mayet, 1903) in France (Coleoptera: Curculionidae: Cryptorhynchinae)

In France since long time only known from the eastern Pyrenean Mountains, Onyxacalles portusveneris (Mayet, 1903) was discovered in the departments of Herault and Gard. This discovery enlarges considerably the European distribution of this beetle. The new distribution is shown and discussed. All specimens were found in Evergreen Oak (Quercus ilex L.) forests. A hypothesis about its natural habitat and an assessment of its ecological requisites in the habitat, are presented. Finally it is concluded, that O. portusveneris is a reliable bio-indicator for long time constant, old Evergreen Oak forest-types in southern France.
