Remarks. China (1938) identified the material of Wollaston’s collection as Deltocephalus striatus (= Psammotettix striatus) and Lindberg (1941) identified it as Psammotettix striatus . Later, Lindberg (1961) reexamined this material and considered it to be P. a l i e n u s. Presently Psammotettix alienus is considered a synonym of Psammotettix striatus (Razvyazkina & Pridantseva, 1968) . This species is a vector of viruses and phytoplasms which cause plant diseases (Della Giustina, 1989).
