Abstract
A new species of the genus Pugnatrypaea Poore, Dworschak, Robles, Mantelatto & Felder, 2019, Pugnatrypaearuiyui sp. nov., collected from the northern South China Sea, is described and illustrated. It is distinguishable from P.pugnatrix (de Man, 1905), P.iranica (Sepahvand, Momtazi & Tudge, 2015), and P.emanata Felder & Robles, 2020 in having the lower margin of the male major cheliped merus lacking a proximal hook. It is distinguishable from P.intermedia (de Man, 1905) and P.lobetobensis (de Man, 1905) in having the upper margins of both cheliped meri unarmed. A key to all species of Pugnatrypaea is provided.
