Distribution. Atlantic (south of 59°N), Pacific ( Australia and New Zealand), and eastern Indian Oceans; Mediterranean ( Vinogradov et al. 1996). The genus Paralycaea is widely distributed in tropical and temperate regions worldwide, mainly in near-surface waters ( Zeidler 2016). In the eastern Pacific from off the west coast of Baja California and the Gulf of California (up to 28°N), north and south of Maria Madre Island, Mexico, and south to off Gorgona Island, Colombia ( García Madrigal 2007, Valencia & Giraldo 2012, Gómez-Gutierrez et al. 2014).

Remarks. Paralycaea gracilis , previously included in the family Pronoidae (see Siegel-Causey 1982, Zeidler 1998), was recently moved to the family Amphithyridae described by Zeidler (2016).
