Gonopore large. Female genitalia with ovipositor extended far beyond the abdomen. Remarks. Exitianus is a worldwide genus of the tribe Chaismini. Ross (1968) revised the Old World species of this genus and presented an intuitive phylogeny based on morphology. Distribution. Worldwide. In Egypt, all over the country. Ecology and habitat. This genus is known to attack agricultural areas that invaded by grasses (Lindberg, 1961), as Alliumcepa L. (Liliaceae), Cucumissativus (Cucurbitaceae), Solanummelongena (Solanaceae), Oryzasativa L. (Graminae), Saccharum officinarum (Poaceae), and Trifolium (Fabaceae). This genus is a vector of phytoplasmas and / or spiroplasmas (Mohammad, 1996; Boukhris-Bouhachem et al., 2007). Economic importance. Minor pest.	en	El-Hady, Rabab M., El-Sayed, Ahmed F.
