    Three species of Tetrasticta Kraatz, 1857 are described and illustrated, all of them from the same locality in Bokeo province, Northwest Laos: Tetrasticta varia sp. nov.; T. crassa sp. nov.; T. puncticeps sp. nov. The habitus and primary sexual characters of T. brevipennis (Bernhauer, 1903) are figured. Aside from the new species, four species are reported from Laos, three of them for the first time. Thus, the currently known Tetrasticta fauna of Laos is composed of seven species. Tetrasticta brevipennis is reported from Malaysia, the Indian province Uttarakhand, and the Chinese province Guangdong, and T. bobbii Zheng et Zhao, 2014 from Myanmar for the first time. In an addendum, Tetrasticta borneana sp. nov. (Malaysia: Sabah) is described and illustrated. The genus now includes a total of 20 species, except for one Aftrotropical species all of them distributed in the southern East Palaearctic and Oriental regions.

    Malayloeblius laoticus sp. nov. (Northwest Laos) and M. tensus sp. nov. (Borneo: Sabah) of the Sahlbergiini, and Dentaphila iniqua sp. nov. of the Aenictoteratini (Northwest Laos) are described, illustrated, and distinguished from previously described species of the respective genera.

    Anomognathus laoticus sp. nov. (Northwest Laos: Bokeo province) and A. triangularis sp. nov. (Northeast Laos: Houa Phan province), the first representatives of the genus to be recorded from Laos, are described and illustrated. A new synonymy is proposed: Placusa nitida Fauvel, 1900 = Anomognathus ispartaensis Örgel, Avci et Özek, 2019; Placusa nitida is reported from Spain, Turkey, and Israel for the first time. The genus Anomognathus Solier, 1849 currently includes 27 valid species distributed in all major zoogeographic regions, except for the Afrotropical region.

    Four species of Chinecallicerus Assing, 2004 are described and illustrated: Chinecallicerus dispersus sp. nov. (China: West Sichuan, West Yunnan); C. unituberculatus sp. nov. (China: Sichuan: Gongga Shan); C. dabaicus sp. nov. (China: Hubei: Daba Shan); C. laoticus sp. nov. (Northwest Laos: Bokeo province). The previously unknown male sexual characters of C. formidabilis Assing, 2019 and the spermathecae of C. serratus Assing, 2009, C. pinnatus Assing, 2017, and C. laevigatus Assing, 2006 are illustrated for the first time. These species, all of them previously known only from their respective holotypes, are reported from additional localities in Sichuan and Yunnan. Chinecallicerus laoticus represents the first record of the genus from Laos, from outside China, and from the whole of the Oriental region, C. dabaicus the first record from the Chinese province Hubei and the easternmost record of the genus. Enormous intraspecific variation was observed for C. dispersus. Including the new species, the genus now includes 22 species, ten of which have been recorded from the Chinese province Yunnan, ten from Sichuan, one from Qinghai, one from Hubei, and one from Laos. As many as 17 species are known only from their respective type localities, twelve of them are represented exclusively by their respective holotypes. A checklist and a newly designed key to species are provided. The distributions of the genus as a whole and of seven individual species are mapped.
