摘要：
We describe two new genera and two new species of freshwater crabs, Megapleonum ehuangzhang n. gen., n. sp. and Luteomon spinapodum n. gen., n. sp., from Guangdong Province, China, based on morphology and mitochondrial 16S rDNA sequences. Megapleonum n. gen. is similar in external appearance to Cantopotamon Huang, Ahyong & Shih, 2017 and Longpotamon Shih, Huang & Ng, 2016, whereas Luteomon n. gen. most closely resembles Yarepotamon Dai & Turkay, 1997 and Tiwaripotamon Bott, 1970. The two new genera, however, are distinctive in their combination of maxilliped 3, male thoracic sternum, male pleon, male gonopod, and female gonopore characters. Molecular data also supports the establishment of the two new genera, with Megapleonum n. gen. belonging to a distinct subclade and Luteomon n. gen. most closely related to Tiwaripotamon.
