ABSTRACT: The genus Dicranolaius Champion, 1921 is revised, the type species, Laius (Dicranolaius) falcifer Champion, 1921 is redescribed, and the differential male characters of the genus are discussed, namely 5-segmented anterior tarsi with the comb above the 2nd tarsomere, enlarged and modified 1st and 3rd antennomeres, and simple head, legs and pronotum lacking impressions or protuberances. A new genus, Australolaius Tshernyshev, gen.n. with a type species Dicranolaius weiri Liu, Ślipiński et Pang, 2015 is described for several Australian Dicranolaius species with male special characters as follows: anterior femora are stout and hollowed externally, urites are elongate and emarginated, and apex of the aedeagus is spicular-shaped. The external appearance, special male characters and genitalia of the type species of the studied genera are illustrated, and a distribution map are provided. A key to the Laius-group genera of the tribe Apalochrini is also provided.

KEY WORDS: Malachiidae, Apalochrini, Laius-group, Dicranolaius, Australolaius, revision, new genus, taxonomy.
