The fundamental value of universal nomenclatural systems in biology is that they enable unambiguous scientific communication. However, the stability of these systems is threatened by recent discussions asking for a fairer nomenclature, raising the possibility of bulk revision processes for “inappropriate” names. It is evident that such proposals come from very deep feelings, but we show how they can irreparably damage the foundation of biological communication and, in turn, the sciences that depend on it. There are four essential consequences of objective codes of nomenclature: universality, stability, neutrality, and transculturality. These codes provide fair and impartial guides to the principles governing biological nomenclature and allow unambiguous universal communication in biology. Accordingly, no subjective proposals should be allowed to undermine them.

The genus Meges Pascoe, 1866 stat. res. is resurrected from synonyms of Monochamus Dejean, 1821 and is made a senior synonym of Magninia Clermont, 1932 syn. nov. Meges currently contains two species, i.e. Meges gravidus (Pascoe, 1858) and Meges tonkineus (Clermont, 1932) comb. nov. The male of the latter species is described for the first time. A related genus Pseudomeges Breuning, 1944 is investigated for comparison and Pseudomeges aureus Bi, Chen & Lin sp. nov. (金斑伪侎天牛, Jîn bân wěi mǐ tiân niú) is described from Yunnan, China. New localities are reported. Illustrations of habitus, endophallic structures and major diagnostic features for all involved taxa are provided.

The genus Neocerambyx J. Thomson, 1861 in China is surveyed, and three new species are described: N. liyuani Lin, Miroshnikov & He, sp. nov. from Sichuan and Hubei provinces, N. miaobenfui Lin, Miroshnikov & He, sp. nov. and N. gui Lin, Miroshnikov & He, sp. nov., both from Hainan Island. Neocerambyx melas (Holzschuh, 2021) is recorded from China (Fujian province) for the first time.

The genera Echinovelleda Breuning, 1936 and Propedicellus Huang, Huang & Liu, 2020 are revised. The latter is considered to be a junior synonym of the former based on a comprehensive morphological investigation, especially on the characteristics of male endophallus. Two new species are described from China, viz. Echinovelleda mumuae Bi & Mu sp. nov. from Yunnan and Guangxi, and E. protochinensis Bi & Lin sp. nov. from Yunnan and Sichuan. New records are reported for previously described taxa including one new country record of a morphologically similar genus, Hechinoschema Thomson, 1857 from China. Illustrations of habitus, endophallic structure, major diagnostic features for all studied taxa, as well as a distributional map are provided.

An article published by Gressitt (1941) has been ignored by all longicornists, including Gressitt himself. However, according to ICZN, it meets all criteria as an official publication, and this status affects three taxa that were formally described therein: Bacchisa (Bacchisa) rigida (Gressitt, 1941) = Chreonoma rigida Gressitt, 1941 = Chreonoma rigida Gressitt, 1942 homonym and syn. nov.; Tetraophthalmus sikang (Gressitt, 1941) = Chreonoma sikang Gressitt, 1941 = Chreonoma sikanga Gressitt, 1942, syn. nov.; Anastathes parva hainana Gressitt, 1941 = Anastathes parva hainana Gressitt, 1942, homonym and syn. nov.

The diversity of the genus Anoplophora Hope, 1839 of Nanling Priority Area for Biodiversity Conservation is surveyed, with the discovery of one new species, A. xuei Lin & Wen, sp. nov. This species is described from Guangxi and Guizhou, China. Illustrations of the habitus and male genitalia of A. xuei Lin & Wen, sp. nov. and the similar A. leechi (Gahan) are provided. Additional locality data for A. leechi is provided.
