Patithelphusa is a genus of freshwater crabs in the family Gecarcinucidae and subfamily Parathelphusinae . This is a newly reported genus from Southeast Asia. [1] The new genus of Gecarcinucid freshwater crab, is described from the Servarayan Hills (Eastern Ghats), Yercaud of Salem District, Tamil Nadu. This genus has been newly erected with a single species, Patithelphusa yercaudensis which is closely related to the genera, Baratha (Bahir & Yeo, 2007) [2] and Travancoriana (Bott, 1969). [3] This species is morphologically differentiated from its close relatives based on the carapace which is broader in this species. The unique male reproductive structure and triangular lobes are other distinct characters. [4]

Etymology

The genus was named to honour a Indian freshwater crab taxonomist Sameer Kumar Pati for his contribution. [5]
