ABSTRACT. The large genus Trachyjulus, in which endemic species range from Sri Lanka and India in the west, through Indochina and the Himalaya, to Malay Peninsula and Indonesia (Sumatra and Java), in the east, currently encompasses 31 species, including four new: T. beroni sp.n. and T. subcalvus sp.n., both from Malaysia, as well as T. unciger sp.n. and T. phylloides sp.n., both from Thailand. In addition, brief redescriptions and abundant illustrations are provided for T. singularis (Attems, 1938) from southern Vietnam and several provinces of Thailand, as well as for T. tjampeanus (Attems, 1903) from Java, whereas the pantropical T. calvus (Pocock, 1893), based on fresh material from Nepal, is a senior subjective synonym of T. nordquisti (Attems, 1909) and T. nordquisti ambiguus Mauriès, 1983 (both syn.n.).
