Figs 1-4. Xenillus baderi sp. n. — 1: body in dorsal view, 2: rostrum, 3: sensillus and humeral region, 4: sculpture of the notogaster It seems almost certain that the various authors using a species name, in fact, meant different species. Furthermore, it is more than certain that far more species live in the Palaearctic region than the number known today. This confusion is also applicable to the species X. clypeator Robineau-Desvoidy, 1839 máX. discrepans Grandjean, 1936. Two subspecies of the latter were described by Pérez-Inigo in 1976 and 1984. Without thorough study of the types these problems cannot be solved. The new species unequivocally belong to the species-group of Pérez-Inigo's X. discrepans, though I regard the type of the group to be X. clypeator. It is beyond doubt that the presently studied taxon comes quite close to the form of X. discrepans sensu Moraza, Herrera and Pérez-Inigo 1980.
