Procleomenes gouverneuri sp. n. (Coleoptera: Cerambycidae) from Baltic amber: the first fossil member of the tribe Sestyrini Lacordaire, 1869

A new fossil cerambycid from Baltic amber, Procleomenes gouverneuri sp. n. (Cerambycinae, Sestyrini) is described. It differs from all extant species in its peculiar elytral pattern formed by a scutellar spot, a pre-apical spot and an apical band. Isosaphanus ferranti Hintz, 1913 (Cerambycidae Xystrocerini) is recognised as a younger synonym of Iridoclava congolensis Bjørnstad, 2014 n. syn. (Cerambycinae, Sestyrini).
