Abstract Two species of Spilogona, S. angustigena sp. n. and S. tatrica sp. n., are described from the Czech Republic and Slovakia, respectively. Both species are characterised by a gynaecomorphic shape of the male head, i.e., by a broad frons and the presence of a pair of orbital setae. Three species with this type of head are already known in the Palaearctic region: S. karelica (Tiensuu, 1935) from Russian Karelia, S. lapponica (Ringdahl, 1932) occurring in Norway and Sweden and redescribed here from material collected recently in Russia and Sweden, and S. spinicosta (Stein, 1907) from Tibet. All five species are compared and a new identification key is given. Apart from the external similarity of the male heads, the species under study are hardly closely related and their dichoptic heads may be explained as a homoplasy among similar ecomorpha.
