A cladistic biogeographic analysis for the Holarctic and Indo‐Chinese regions was undertaken based on seven genera of the tribe Cidariini: Cidaria Treitschke, Thera Stephens, Pennithera Viidalepp, Heterothera Inoue, Callabraxas Butler, Gandaritis Moore and Eulithis Httbner. Smallest coincident ranges of two species recognized 11 endemic areas. The study has two aims: to construct a hierarchical structure of those areas, and to recognize dispersal events. Under two assumptions [widespread taxa mapped (identical as assumption 0) and widespread taxa not mapped (identical as assumption 1)] the 11 endemic areas were mapped with 72 taxa. The best resolved area cladograms under the two assumptions differ in the placement of one endemic area, northern Europe. Area relationships found in this present analysis are congruent with the current landmass configurations: (North America, (Europe, (northern India, (southwestern Asia, (Baikal area, (south China, (Taiwan, (Russian Far East, Japan. These area cladograms postulate at least three vicariance events: (1) between North America and the Palaearctic; (2) western‐eastern Palaearctic; (3) northern India–the rest of Asia. The approach to recognize dispersed taxa by pruning each taxon suggests that most dispersal events occurred in East Asia: from the Baikal area or south China to the Russian Far East; and from the Russian Far East to Japan. Relationships among endemic areas are briefly discussed.
