Lagenivaginopseudobenedenia is a genus of monopisthocotylean monogenean, included in the family Capsalidae. The type-species of the genus is Lagenivaginopseudobenedenia etelis . The genus includes only 2 species, which are both parasitic on the gills of marine fish of the family Lutjanidae.

Morphology

Species of the genus Lagenivaginopseudobenedenia are, like most monogeneans of the family Capsalidae, flat with a posterior disc-shaped haptor which attaches to the gill of their host. Their distinctive feature is a “vagina lageniform, between uterus and right intestinal limb, opening almost midventrally behind cirrus pouch”.

Etymology and curiosity of zoological nomenclature

The etymology of this extremely long name involves three steps:

  • Satyu Yamaguti, in 1966, wrote that the “compound generic name Lagenivaginopseudobenedenia refers to the lageniform vagina and close relationship to Pseudobenedenia”.
  • The name of the genus Pseudobenedenia Johnston, 1931 itself was previously formed from the prefix ‘Pseudo-’ and the genus name Benedenia by Thomas Harvey Johnston in 1931. ‘Pseudo-’ (from Greek ψευδής, pseudes, "lying, false") is commonly used in creating new scientific names for a taxon that superficially appears to be a taxon, but actually is another.
  • Benedenia Diesing, 1858 was a name created by the Austrian zoologist Karl Moriz Diesing in 1858 to honour the Belgian helminthologist Pierre-Joseph van Beneden.

    • Lagenivaginopseudobenedenia, with 27 letters and 17 syllables, is possibly the longest valid generic name of the zoological nomenclature for a non-fossil organism.

    Hosts

    Hosts of species of monogeneans of the genus Lagenivaginopseudobenedenia are parasitic on fish which are members of the genus Etelis (family Lutjanidae), found in deep-sea in the Pacific Ocean.

    Species

    Only two species are currently known in this genus.

  • Lagenivaginopseudobenedenia etelis Yamaguti, 1966, parasite of the deep-water red snapper Etelis carbunculus off Hawaii and of the deepwater longtail red snapper Etelis coruscans off New Caledonia.
  • Lagenivaginopseudobenedenia tinrowi Timofeeva, 1995 parasite of the deep-water red snapper Etelis carbunculus in the Pacific Ocean (26°41' N, 135°22' E).
