Paussus brancuccii sp.nov., an unusually abundant species of the Paussus jousselinii group from Laos and South China (Coleoptera, Carabidae, Paussinae, Paussini)

A new myrmecophilous species of flanged bombardier beetles is described from northeastern Laosand China (Guangxi), Paussus brancuccii sp.nov. This species stands out from other members of the Paussusjousselinii group and most other Paussines by the large number of specimens available for study from onesingle locality. The long series allows an assessment of the variability of the shape of the antennal club. Somespecimens were collected together with the possible host ants Tetramorium sp. and Pheidole sp. (Myrmicinae).
