| Abstract: | Two new genera Petropsis gen. n., and Menatorhis gen. n., and two species, Petropsis rostrata gen. et sp. n. (Ithyceridae) and Perapion menatensis sp. n. (Brentidae), are described from the Paleocene of Menat (France). Petropsis rostrata gen. et sp. n. is similar to Cretocar luzzii Gratshev et Zherikhin (2000) but differs from it in the comparatively short ventrites 1 and 2, almost straight and not dilated metatibiae, short precoxal portion of the prosternum, slightly convex elytra and antennae inserted more closely to the middle of the rostrum. Perapion menatensis sp. n. is similar to Perapion antiquum (Gyllenhal, 1833) but differs from it in the straight rostrum, sparser and finer punctures of the pronotum, and somewhat larger body. The families Ithyceridae and Brentidae are recorded for the first time in the Paleocene of Menat. The systematic positions of Balaninus elegans Piton (1940) (type species of Menatorhis gen. n.) and Hipporhinus ventricosus Piton (1940) are discussed. |
