The composition of the subtribe Manobiina Bechyne et Bechyne, 1975 is reconsidered based on cladistic analysis of morphological characters. The following genera are retained: Alema Sharp, 1876, Analema Samuelson, 1973, Eudoliamorpha Scherer, 1989, Exoceras Jacoby, 1891, Leptophysa Baly, 1877, Lipromela Chen, 1933, Lipromima Heikertinger, 1924, Lipromorpha Chujo et Kimoto, 1960, Liprus Motschulsky, 1860, Manobia Jacoby, 1885, Pseudoliprus Chujo et Kimoto, 1960, and Taiwanoliprus Komiya, 2006. A description of the subtribe Manobiina, diagnosis and key to genera are given. A morphological analysis of the genera attributed to the subtribe is provided and discussed. A possible fossil representative of Manobiina is recorded from Late Eocene of Rovno amber. A new combination is proposed: Leptophysa trinitatis (Bryant, 1927) = Exoceras trinitatis (Bryant, 1927) comb.n. The lectotype of Liprus punctatostriatus Motschulsky, 1860 is designated.
