The Oriental tettigonioid genera Lipotactes and Mortoniellus were formerly included in the Australian subfamily Tympanophorinae. The genera however differ from Tympanophora by the tuberculate thoracic sterna, the small thoracic auditory spiracle, the compressed protibia, the spination of pro- and mesotibiae, the shape of the pronotum, and the possession of styli on the male subgenital plate. The erection of a new subfamily, Lipotactinae, is proposed to include Lipotactes and Mortoniellus. Mortoniellus is retained as a valid genus, but its differences from Lipotactes are redefined. The genera differ in the shape of the frons, the position of the fastigium verticis and the sculpturation of the pronotum. The species are revised. L. hamatus (Karny, 1931) comb. n. and L. sinicus (Bei-Bienko, 1959) comb. n. are transferred to Lipotactes, M. azuriventer (Karny, 1924) comb. n. to Mortoniellus, M. concolor Kästner, 1933 stat. n. is upgraded to species level, M. chopardi Zeuner, 1936 syn. n. becomes a new synonym of M. karnyi Griffini, 1909. Eight species are new to science: L. siebersi sp. n., L. virescens sp. n., L. longicauda sp. n., L. minutus sp. n., L. sulcatus sp. n., M. ovatus sp. n., M. macrognathus sp. n. and M. parvus sp. n. As a result, Lipotactes contains now 14, Mortoniellus 7 species. A key to the species and a distribution map is given. Information on stridulation of some of the species is also provided.
