In synonymy:
Phoebe C. L. Koch, 1850 = Sittisax Prószyński, 2017 (Prószyński, 2017a: 48, by transfer of the type species)

type Euophrys saxicola C. L. Koch, 1846; gender masculine

N.B.: the synonymy with Sitticus by Breitling, 2019b: 31 was not accepted because based mainly on COI (see FAQ 7) and rejected by Maddison et al., 2020: 34; considered a synonym of Phoebe C. L. Koch, 1850: 63 [urn:lsid:nmbe.ch:spidergen:06213] (described as a subgenus of Euophrys C. L. Koch, 1834; type Euophrys saxicola C. L. Koch, 1846), preoccupied in Coleoptera by Audinet-Serville, 1835, by Prószyński, 2017a: 48 (by transfer of the type species).

Transferred to other genera:
Sittisax dzieduszyckii (L. Koch, 1870) -- see Attulus
