Abstract
A new monotypic genus Minimania Gültekin & Lyal gen. nov. is described for M. parvula (Faust, 1898) comb. nov. from Lachnaeus, which has the smallest body size in the tribe Lixini (Curculionidae: Lixinae). It is similar to the genus Lachnaeus Schoenherr, 1826 in the common possession of long erect setae on the body, but it differs from this genus in the following unique characters: rostrum with straight ridge and linear sulcus on pregena and elongate pseudosytlus on gonocoxites. Lectotypes are designated for Lachnaeus crinitus Boheman, 1835, Lachnaeus gibbosus Petri, 1907 and Stolatus horridus Reitter, 1890. A key to the species of Lachnaeus is given and digital images showing distinctive morphological characters are presented for each species.
