A single fossil species, formerly included in the genus Benthesicymus, is now placed in a separate genus, Palaeobenthesicymus.[3]

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

• Bathicaris Vereshchaka & Lunina, gen. nov.
  • Bathicaris brasiliensis (Spence Bate, 1881), comb. nov.
  • Bathicaris cereus (Burkenroad, 1936), comb. nov.
  • Bathicaris iridescens (Spence Bate, 1881), comb. nov.
  • Bathicaris seymouri (Tirmizi, 1960), comb. nov.
  • Bathicaris strabus (Burkenroad, 1936), comb. nov.
  • Bathicaris urinator (Burkenroad, 1936), comb. nov.
• Dalicaris Vereshchaka & Lunina, gen. nov.
  • Dalicaris altus (Spence Bate, 1881), comb. nov.
• Maorrancaris Vereshchaka & Lunina, gen. nov.
  • Maorrancaris investigatoris (Alcock & Anderson, 1899), comb. nov
• Trichocaris Vereshchaka & Lunina, gen. nov.
  • Trichocaris bartletti (Smith, 1882), comb. nov.
  • Trichocaris tanneri (Faxon, 1893), comb. nov.
