“…Also within the Prionini, the genera Apterocaulus Fairmaire 1864, Callistoprionus Tippmann, 1953, Microarthron Pic, 1900, Miniprionus Danilevsky, 2000, Prionacalus White, 1845, Prionoblemma Jakovlev, 1887, Emphiesmenus Lansberge, 1884, and Psalidocoptus White, 1856 are excluded because of their very different shapes of the pronotum and body. Braderochus Buquet, 1852 has, in contrast to the new species, a much longer antennomere 3, very large eyes, close to the bases of the antennae, a narrow anterior margin of the pronotum and more arcuate elytral sides (Santos-Silva & Martins 2005a, 2005b. Species of the genus Derobrachus Audinet-Serville, 1832 have strong spines at an anterolateral angle of the pronotum and usually much longer elytra (Santos-Silva 2007), unlike the new fossil species.…”

Palaeosphryon menatensis gen. et sp. nov., first unambiguous representative of the longhorn beetle subfamily Prioninae from the Paleocene of Menat (France), is described and illustrated. The new fossil is placed into the tribe Prionini, showing some similarities with some species of the extant genera Osphryon (Papua New Guinea) and Titanus (Brazil, Colombia, Guianas, Ecuador, Peru), viz. in general body shape, antennomere 3 as long as first and second together but shorter than the length of fourth plus fifth, elongate elytra, and small spines on the lateral margin of the pronotum disposed in a relatively similar way as in Osphryon. Nevertheless, the exact affinities of the new fossil within the Prionini remain uncertain because of the lack of a recent phylogenetic analysis in which it could be integrated. This fossil beetle is exceptional for its very large size, with a body 70 mm long. Some other large longhorn beetles have been found in the same outcrop, and are awaiting description. The positions of the previously described Cerambycidae from Menat are also discussed. This exceptional fauna of Cerambycidae is in accordance with the current palaeoenvironmental reconstruction for the Menat Konservat-Lagerstätte, as a small maar lake surrounded by a warm and humid, probably evergreen forest.
