Pages 505-515
Acta Entomologica Musei Nationalis Pragae | 2011/51/2

The synonymy of Chalcionellus libanicola (Marseul, 1870) and Chalcionellus orcinus Reichardt, 1932 is rejected based on the examination of the type specimens of both species and Chalcionellus orcinus stat. restit. is reinstated as a valid species. The two species differ mainly in the structure of frontal disc, length of elytral striation, shape and punctuation of pronotum, absence/presence of slight metallic luster on the elytra and male genitalia. The lectotype of Chalcionellus libanicola is designated.
