2005 taxonomy

Acochlidiidae was classified as the only family within the superfamily Acochlidioidea Küthe, 1935 in the taxonomy of Bouchet & Rocroi (2005).[4] Palliohedylidae was in turn classified as the only family within the superfamily Palliohedyloidea.[4]

2010 taxonomy

Schrödl & Neusser (2010)[1] redefined the taxonomy of Acochlidiacea in 2010, placing the family Acochlidiidae in the clade Hedylopsacea.[1]

Genera

According to Schrödl & Neusser (2010),[1] there are three genera in the family Acochlidiidae:[1]

Acochlidium Strubell, 1892[1][5]

Palliohedyle Rankin, 1979[1]

  • Palliohedyle sutteri - synonym: Acochlidium sutteri Wawra[1][9]
  • Palliohedyle weberi - synonym: Acochlidium weberi Bergh, 1896[1][6]

Strubellia Odhner, 1937[1]

  • Strubellia paradoxa (Strubell, 1892) - synonym: Acochlidium paradoxum Strubell[1]
  • Strubellia wawrai Brenzinger, Neusser, Jörger & Schrödl, 2011
gollark: Do any of these people actually like to see stuff like "Here's a Wumpus for now" in the UI?
gollark: And some languages have a grammatical formal/informal distinction - and they use the formal grammar, but with the really informal wording - which makes it even weirder.
gollark: Apparently they try and use the same sort of thing in other languages...
gollark: On a related note, it annoys me a lot that Discord seem to want to appeal to "gamers"; I don't even know *which* gamers, honestly; with the weird phrasing they use in the UI.
gollark: If it was federated and open, people would be able to move off it more easily.
