Replacement names for three preoccupied genus-group names of Cetoniinae (Coleoptera: Scarabaeidae).

The names of three genus-level taxa of Cetoniinae from Southeast Asia are reviewed. Aurelia Thomson, 1880, currently a subgenus of Ixorida Thomson, 1880, is preoccupied by Aurelia Lamarck, 1816, and Emas Allsopp, Jákl & Rey, new replacement name, is proposed. This results in Ixorida (Emas) decorata Antoine, 1986, Ixorida (Emas) gloriosa Jákl, 2014, Ixorida (Emas) kaorui Jákl, 2019, Ixorida (Emas) philippei Sakai & Nagai, 1998, and Ixorida (Emas) thoracica (Wallace, 1867). Legrandia Jákl, 2019, currently a subgenus of Ruteraetia Krikken, 1980, is preoccupied by Legrandia Beddome, 1883, and Legrandetia Allsopp, Jákl & Rey, new replacement name is proposed, resulting in Ruteraetia (Legrandetia) pahangensis Jákl, 2019. Sternoplus Wallace, 1867 is preoccupied by Sternoplus Mulsant & Rey, 1864, and Walsternoplus Allsopp, Jákl & Rey, new replacement name is proposed, resulting in Walsternoplus schaumii (White, 1856), new combination, and Walsternoplus chicheryi (Antoine, 1999), new combination.

Contribution to the knowledge of the Prioninae (Coleoptera, Cerambycidae) from the Mizoram State (India), with the first report of the genus Megobaralipton/ Lepesme amp; Breuning and new records from the country.

Five species of Prioninae from the Indian state of Mizoram were studied: Megobaralipton kalimantanum (Komiya Makihara, 2001); Nepiodes bowringi (Gahan, 1894); Anomophysis hainana (Gressitt, 1940); Eurypoda (Eurypoda) nigrita Thomson, 1865 and Eurypoda (Neoprion) batesi Gahan, 1894. New country records are provided to: Megobaralipton kalimantanum (Komiya Makihara, 2001); Anomophysis hainana (Gressitt, 1940); Eurypoda (Eurypoda) nigrita Thomson, 1865; Eurypoda (Neoprion) batesi Gahan, 1894. Nepiodes bowringi (Gahan, 1894) is record for the first time from the Indian state of Mizoram. Detailed taxonomic position of all species, their host plant, and images of dorsal habitus are provided.

The genus Ceratophyus Fischer von Waldheim, 1824 (Coleoptera: Geotrupidae) in China, along with description of a new species.

Ceratophyus amdoensis Král Jákl, new species from Gansu and Qinghai Provinces of China is described, illustrated and compared with its congeners so far known from China and adjacent countries. A key to identification of males of Chinese species of Ceratophyus Fischer von Waldheim, 1824 is provided. Ceratophyus polyceros (Pallas, 1771) is excluded from the fauna of China. First province records of C. dauricus (Jekel, 1866) from Hebei (China) and Hentiy (Mongolia) and first province records of C. sinicus Zunino, 1973 from Hebei, Ningxia and Shaanxi (China) are reported. Distribution of five species so far known from China is summarized and mapped.
