Family Issidae Spinola, 1839

Currently, the family Issidae comprises one subfamily with five tribes ( GNEZDILOV 2003a). The traditional classification of the family is based mostly on the characters of fore and hind wings and in particular on the development or reduction of hind wings. However, the state of reduction seems to vary within genera and the reduction is likely to have evolved independently several times in different taxa of the Issidae (GNEZDILOV, in prep.). For these reasons, I consider the presence of the trilobed hind wing as an insufficient character for the definition of a separate tribe Thioniini ( MELICHAR 1906, GNEZDILOV 2003a) and place Thabena Stål, 1866 and Euroxenus gen. nov. in the tribe Issini . I suggest treating Thioniini Melichar, 1906 as a junior synonym of Issini Spinola, 1839 .
