Benthesicymus is a genus of prawns, containing the following species:^[1]

• Benthesicymus altus Spence Bate, 1881
• Benthesicymus armatus MacGilchrist, 1905
• Benthesicymus bartletti Smith, 1882
• Benthesicymus brasiliensis Spence Bate, 1881
• Benthesicymus cereus Burkenroad, 1936
• Benthesicymus crenatus Spence Bate, 1881
• Benthesicymus howensis Dall, 2001
• Benthesicymus investigatoris Alcock & Anderson, 1899
• Benthesicymus iridescens Spence Bate, 1881
• Benthesicymus laciniatus Rathbun, 1906
• Benthesicymus seymouri Tirmizi, 1960
• Benthesicymus strabus Burkenroad, 1936
• Benthesicymus tanneri Faxon, 1893
• Benthesicymus tirmiziae Crosnier, 1978

A single fossil species, formerly included in the genus Benthesicymus, is now placed in a separate genus, Palaeobenthesicymus.^[2]

A 2020 study showed Benthesicymus to be paraphyletic with five robust clades, 4 of which were diagnosed as new genera:^[3]
