  ## Etymology
  
  The name of this genus is an amalgam of Forster in honour of Johann Reinhold Forster (1729–1798) – a naturalist aboard Captain Cook’s second voyage on HMS Resolution; he collected the type on this voyage, describing it and naming it Blennius varius – and -ygion, the second part of the genus Tripterygion, into which F. varius and F. nigripenne had been placed.
