Abstract
This is the second part of the revision of Chinese, Lao and Vietnamese Alycaeidae (superfamily Cyclophoroidea), and covers the genera Alycaeus and Pincerna. Three new species are described: Alycaeus goliath Páll-Gergely, n. sp. (central Laos), Pincerna acroptychia n. sp. (Ha Giang Province, northern Vietnam), Pincerna viginticostatus n. sp. (Lạng Sơn Province, northern Vietnam). Pincerna vallis Z.-Y. Chen & M. Wu, 2020 is treated as a junior synonym of Pincerna costulosus (Bavay & Dautzenberg, 1912), and Pincerna clausus D. S. Do & T. S. Nguyen, 2022 as a synonym of Pincerna vanbuensis (Bavay & Dautzenberg, 1900).
