Sixteen species of Issidae (Hemiptera: Fulgoromorpha) belonging to the tribe Sarimini were collected in recent years in Bach Ma National Park and Phong Dien District in Thừa Thiên-Huế Province in Central Vietnam. Among these, fourteen are new to science, and five new genera were recognized. Three species belong to the new genus Bachmarima gen. nov., erected for the new species Bachmarima expansa gen. et sp. nov. (type species) from Bach Ma and Phong Dien, B. recta gen. et sp. nov. from Bach Ma, Phong Dien, and Da Krong Nature Reserve (Quang Tri Province), and B. valida gen. et sp. nov. from Bach Ma, Phong Dien, and Da Krong Nature Reserve (Quang Tri Province); three species belong to the new genus Caimocus gen. nov., erected for the new species Caimocus elephas gen. et sp. nov. (type species) from Bach Ma, and Hoang Hoa (Quang Tri Province), C. robustus gen. et sp. nov. from Bach Ma, and C. sinuatus gen. et sp. nov. from Bach Ma; one species belongs to the new genus Civetissus gen. nov., erected for the new species Civetissus pagumoides gen. et sp. nov. (type species) from Bach Ma; one species belongs to the new genus Lobosarima gen. nov., erected for the new species Lobosarima lobata gen. et sp. nov. (type species) from from Bach Ma, Phong Dien, and Ba Na-Nui Chua Nature Reserve (Da Nang Province); one species belongs to the new genus Retirima gen. nov., erected for the new species Retirima angulata gen. et sp. nov. (type species) from Bach Ma. The genus Eusarima Yang, 1994 is recorded from Vietnam for the first time, with three new species: Eusarima bachmana sp. nov. from Bach Ma, E. boevei sp. nov. from Bach Ma and Eusarima bourgoini sp. nov. from Bach Ma, Phong Dien, and Ba Na-Nui Chua Nature Reserve (Da Nang Province). The distribution of the genus Longieusarima Wang, Bourgoin & Zhang, 2017 is greatly expanded to the south with one new species Longieusarima bachmana sp. nov. from Bach Ma. The genus Microsarimodes Chang & Chen, 2019 is recorded from Vietnam for the first time, with one new species: Microsarimodes backeljaui sp. nov. from Bach Ma. The diversity of the family Issidae and tribe Sarimini in Vietnam, and the delimitation of the species and genera of Sarimini, are briefly discussed. These fourteen species add to the eight species of the tribe Hemisphaeriini and to the eight species of the tribe Parahiraciini previously recorded / described from Thừa Thiên-Huế Province, which now counts 30 described species of Issidae. The Vietnamese fauna now counts 84 species in 42 genera in this family.
