In this paper, three new species of the alycaeid genus Dicharax Kobelt & Möllendorff, 1900 are described, namely Dicharax floridus n. sp., Dicharax spatiosus n. sp. (Both from Shan State, Myanmar) and Dicharax kosztarabi n. sp. (from Thailand). All three new species are known from their holotypes.
Anauchen (?) kozari n. sp. is described from Luang Prabang province, central Laos. This new species is temporarily placed in the genus Anauchen due to the similarity of its apertural barriers to those of A. messageri (Bavay & Dautzenberg, 1904). Boysidia gereti Bavay & Dautzenberg, 1904 is a junior synonym of Anauchen rochebruni (Mabille, 1887) (originally described as Hypselostoma).
