In the present paper Bothrichara anggi sp. nov. (New Guinea), B. grisea sp. nov. (New Guinea), Bothrionota ruzzieri sp. nov. (Sulawesi), Exostira transmontana sp. nov. (China, India, Myanmar), Kaindilagria opposita sp. nov. (New Guinea), Macrocasnonidea bifurcata sp. nov. (Borneo), and Oreogria arfak sp. nov. (New Guinea) are described and illustrated. New synonymy is proposed for Bothrichara Borchmann, 1916 (= Calogria Borchmann, 1916 syn. nov.), Borchmannia violaceocincta (Borchmann & Pic, 1912) (= Rouyerus (Borchmannia) violaceocincta var. diversicollis Borchmann & Pic, 1912 syn. nov., = R. (B.) dissimilis Borchmann in Borchmann & Pic, 1912 syn. nov., = R. (B.) dissimilis var. rufithorax Pic in Borchmann & Pic, 1912 syn. nov., = R. (B.) dissimilis var. lineaticollis Borchmann & Pic, 1912 syn. nov., = Borchmannia akiyamai Merkl, 1988 syn. nov.; = Borchmannia masumotoi Merkl, 1988 syn. nov.) and Chlorophila gemma Telnov, 2021 (= C. carinadorsum Liang, Zhou & Chen, 2022 syn. nov.). Taxonomic position of Costiferolagria grossepunctata (Borchmann, 1916) and C. octocostata (Borchmann, 1916) is discussed and lectotype is designated for Auristira octocostata. Interspecific variability is described and discussed for Sora marmoreipennis Merkl, 2019. Images of Borchmannia violaceocincta, Costiferolagria grossepunctata (Borchmann, 1916), C. octocostata (Borchmann, 1916), Macrocasnonidea quadrimaculata (Pic, 1912), and Sora bimucronata (Pic, 1926) are presented for the first time. New information is provided on the distribution of 25 East Asian and Papuan Lagriinae Latreille, 1825 (1820) including several corrections and additions.
