? Euscelis incisus (Kirschbaum, 1858)

Athysanus incisus Kirschbaum, 1858: 10

Athysanus plebejus; China, 1938: 46

Euscelis plebejus ?; Lindberg, 1961: 66

Distribution. Palaearctic region including Macaronesia but here known only from Madeira. DESERTA GRANDE: locality unknown (China, 1938). ISLET CHÃO: locality unknown (China, 1938). PORTO SANTO: reported from few localities (China, 1938; Lindberg, 1961). Remarks. This species shows seasonal variation in the morphology of genital structures (Muller, 1983). Lindberg (1961) examined China’s material of E. incisus from Porto Santo and Desertas and identified it tentatively as E. plebejus but considered that could belong also to E. lineolatus Brullé. However, part of this material could belong also to E. ormaderensis Remane 1968 (see Remane, 1968) or to a different species. Euscelis incisus is a vector of several plant diseases (Della Giustina, 1989) and its presence on Madeira should be confirmed.

Habitat and food plants. Unknown.
