can Ocyochterus victor (Bo l i v a r , 1879). Species of the genus Ochterus show only 7 cells (figs. 4, 11) and Megochterus 20 cells (fig. 9). The small size of at least 3.3 mm of Riegerochterus baehri spec. nov. is typical for Austra- lian species of Ochterus (Baeh r , 1989): O. australicus Ja c z ew s k i , 1934 (3.7 - 4.55 mm), O. baehri baehri Ri ege r , 1977 (3.65 - 4.25 mm), O. baehri rie­geri Baeh r , 1989 (3.5- 4.05 mm), O. brachy­ soma Rie­ge r , 1977 (3.45-3.85 mm) and O. atridermis Baeh r , 1989 (3.35-3.5 mm). However, the dorsal body surface of body, particularly of the hemelytra of all these species are like other spe- cies always spotted. One should also pay attention to the unusual “acutangulate” pro- notum of Ochterus acutangulus (Cha m p i o n , 1901), (Dr a k e 1952, fig. 1), from Central America, which greatly differs from a typical pro- notal configuration of all species of the genus Ochterus and most probably must be transferred to a separate genus after a special morphological investigation.
