Abstract
A new fossil cockroach, Ectobius danekrae sp. nov., is described on the basis of a single male adult individual from late Eocene Danish amber. This is the third representative of the genus Ectobius Stephens, 1835 from Eocene ambers. The new species exhibits plesiomorphic characters of small right stylus and subsymmetrical claws, compared to the known fossil and living species of the genus. The references to Ectobius balticus (Germar et Berendt, 1856) and Margattea Shelford, 1911 sp. presence in Danish amber are insufficient.
