FIGURE 6. Hypothesis O6 of phylogeny of the Opiliones (Hansen & Sørensen 1904). The Danes kept the solid Plagiostethi (= "Palpatores" in blue) and dismantled the Apagosterni resurrecting and firstly naming Thorell's Dyspnoi as opposed to the Eupnoi. This hypothesis was also defended by Roewer (1923) and Shear (1975) and became the classic triad of the 20th century: Cyphophthalmi, Palpatores and Laniatores.
