A highly distinctive genus of pselaphine tribe Batrisini, Feabatrus gen. nov., is described based on Leonardo Fea’s historical collection housed in the Museo Civico di Storia Naturale “G. Doria” di Genova, Italy. The genus includes two new species from Myanmar, F. myanmarensis sp. nov. and F. leonardoi sp. nov. Feabatrus gen. nov. is characterized and can be separated from related genera by large-sized body with long, suberect setae on the dorsal surface and antennae, pronotum with large marginal, discal and antebasal spines, elytra with a smooth disc and shallow discal striae, inner two basal foveae close, and lacking subhumeral fovea, distinct constriction between the elytra and the abdomen, and the female possessing an asymmetric genital complex as well as a flat, sub-trapezoidal tergite 5 (VIII) that has a small nodule in the middle of the posterior margin. A single female from Yunnan, southwestern China, representing a third species, is briefly described but left unnamed.
