Distribution: India, Pakistan, Palestine, Israel, Egypt, Uganda ( Ghauri, 1966; Fletcher, et al., 2016); Oceania: Norfolk Island ( Australia), Iraq ( Metcalf, 1967), Saudi Arabia ( Dlabola, 1980).

Ecology and biology. The most common Orosius species worldwide and known as a vector of various diseases e.g. Sesame phyllody phytoplasma and Chickpea chlorotic dwarf virus in different countries. The abundance of O. albicinctus   is markedly higher in April in all localities in Saudi Arabia ( Figs 59–61 View FIGURES 57–62 ). Most specimens were collected from Jazan to north of Riyadh region by light trap. Most of these localities has a diverse flora of plants and determination of any host plant is not yet possible.

Diagnosis: O. albicinctus   can be distinguished by the characters of the aedeagus, spine at base of anal tube and pygofer: aedeagal shafts branches extent with significant diverging, base with a little projection laterally ( Figs 24–25 View FIGURES 21–32 ); spine of anal tube very long and narrowed arising from base ( Fig. 48 View FIGURES 45–56 ); pygofer broadly rounded with median elongation posteriorly ( Fig. 38 View FIGURES 33–44 ).
