Two Coleoptera species described by Ferdinand Joseph Schmidt in 1834 have been forgotten. One, Chlaenius carniolicus, is placed here in synonymy with Chlaenius (Chlaenites) spoliatus (Rossi, 1792), while the other, Oedemera lippichii, is synonymized with Nacerdes (Xanthochroa) carniolica carniolica Gistel, 1834 (new synonymies). Chlaenius carniolicus Gistel, 1834, a primary homonym of C. carniolicus Schmidt, 1834 which has been forgotten too in the literature, is also placed in synonymy with Chlaenius spoliatus (new synonym).
