R.J. Wang, a new monotypic genus for (Wall. ex Kurz) M.D.Yuan & R.J.Wang, new combination, is segregated from the - complex, based on morphological and molecular evidence. Phylogenetically, the new genus is sister to , from which it differs by a combination of morphological characters: herbaceous habit, terminal inflorescence with subtended leaves, heterostylous flowers, indehiscent fruits and pollen with double microreticulate tectum. A key to the genera of the complex in China is provided for further identification.

- The literature review focuses on identifying larvae of the Calopterygoidea group in the Oriental Realm, aiming to help researchers classify them accurately despite scattered information.
- It offers a comprehensive key for families and some generas, highlighting areas where knowledge is lacking regarding larvae identification.
- Of the 50 genera in the region, larvae for 28 are known, but many still lack clear morphological traits for confident identification, especially in the Chlorocyphidae family.
