genus is not homogeneous, it dissolves by the first glance into two large species groups on the basis of the long or short dorsal hairs; in addition, there are many insufficiently described or incorrectly identified species. The new species belongs in the group with short hairs. In this subdivision, the identification of F. europaeus Willmann, 1935, represents the first problem. In my opinion, all data referring to this species are incorrect. A study of the Hungarian specimens leave no doubt that they agree with P. pilosus Hammer, 1952, as discussed by PEREZ-INIGO, which, if compared with the figures, cannot be identical with HAMMER' s species. The problem can be solved only by the examination of the type-materials. The Tunesian specimens differ unequivocally from these taxa by their exceptionally short dorsal hairs and especially by the extremely short pair of interlamellar hairs, and appear to belong rather in the alliance P. glaber Mihelcic, 1956 (sensu PEREZ-INIGO, 1974). This also has very short notogastral hairs and a similarly short interlamellar pair. However, this latter is incrassate and heavily ciliate, while in the Tunesian specimens just as thin and smooth as the notogastral setae. LITERATURE BALOGH, J.
