FIGURE 2. Hypothesis O 2 in Opiliones are no longer the same—on suprafamilial groups in harvestmen (Arthropoda: Arachnida)

FIGURE 2. Hypothesis O 2 of phylogeny of the Opiliones (Sundevall 1833). The original concept of the Opiliones (" Opiliones " in green) excluded the Cyphophthalmi (here represented by Siro). This group is currently called Phalangida (in blue). Ischyropsalis was still to be unknown for 6 years.

FIGURE 1. Hypothesis O 1 in Opiliones are no longer the same—on suprafamilial groups in harvestmen (Arthropoda: Arachnida)

FIGURE 1. Hypothesis O 1 of phylogeny of the Opiliones (Latreille 1802). The clade which is today called Opiliones (in blue, below) was originally called " Phalangiens " (in green, above). Members of the Laniatores and of the Ischyropsalidoidea were then unknown. The name Phalangida (as many others) has undergone a change of circumscription over time.

FIGURE 7. Hypothesis O 7 in Opiliones are no longer the same—on suprafamilial groups in harvestmen (Arthropoda: Arachnida)

FIGURE 7. Hypothesis O 7 of phylogeny of the Opiliones (Mello-Leitão 1944). This author combined some older hypotheses such as the dichotomy Laniatores versus Palpatores (still using the original Thorell's concept) and reintroduced the Apagosterni.

FIGURE 6. Hypothesis O 6 in Opiliones are no longer the same—on suprafamilial groups in harvestmen (Arthropoda: Arachnida)

FIGURE 6. Hypothesis O 6 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 20 th century: Cyphophthalmi, Palpatores and Laniatores.

FIGURE 5. Hypothesis O 5 in Opiliones are no longer the same—on suprafamilial groups in harvestmen (Arthropoda: Arachnida)

FIGURE 5. Hypothesis O 5 of phylogeny of the Opiliones (Pocock 1902). Pocock suggested a group formed by today's Phalangioidea + Ischyropsalidoidea, thus introducing the name and the concept of Apagosterni. Loman (1903) was the first to accept this clade, which alternately lost and regained favor, but endured for a century.
