The expanded description of Hemiphyllodactylus hongkongensis Sung, Lee, NG, Zhang & Yang, 2018 is provided based on four newly collected specimens from eastern Guangdong Province, China, which is beyond its previously known range. The new collection also fills the distribution gap of the genus Hemiphyllodactylus in the region. Due to the absence of sufficient data, we recommend Hemiphyllodactylus hongkongensis be listed as Data Deficient (DD) in the IUCN conservation status categorization.
