This dataset contains the digitized treatments in Plazi based on the original journal article Chen, Weiqiang, Wang, Yinglun, Zhang, Yalin (2026): Three new species of the newly recorded genus Monochorhynchus Muir, 1917 from China, with observations on the fine structure of the mouthparts (Hemiptera: Fulgoromorpha: Derbidae). European Journal of Taxonomy 1043: 62-86, DOI: 10.5852/ejt.2026.1043.3205, URL: europeanjournaloftaxonomy.eu/index.php/ejt/article/download/3205/14227 Abstract.

The planthopper genus Monochorhynchus Muir, 1917 is reviewed, newly recorded from China, and transferred to the subtribe Lyddina. Three new species from China, M. dehongensis sp. nov., M. obscurus sp. nov., and M. psammochroma sp. nov., are described and illustrated based on morphological characteristics. A checklist of the species of Monochorhynchus, including their geographic distribution, is provided, along with an identification key to the known species.
