Distribution. Ovaticoccus species are mainly known from the Nearctic Region, mostly in South-western part of the USA (Miller and McKenzie, 1967), except O. amplicoxae Williams & Martin (2003), which was described from the Neotropic Region, and might not belong to Ovaticoccus . The species O. agenjoi (Gomez-Menor Ortega), known from the Palaearctic region (Canary Isl.), was removed from Ovaticoccus by Kozár and Konczné Benedicty (2008a), and placed in the new genus Hispaniococcus. O. agavium is an alien species in Palaearctic and Ethiopian regions (United Kingdom, Italian mainland and Sicily, France, Russia, Ukraine, Eritrea, Ethiopia), where it was introduced with ornamental or cultivated Agavaceae (i.e. Agave sisalana).

Ovaticoccus species live on plants belonging to Agavaceae, Asteraceae, Ephedraceae, Lamiaceae, Liliaceae, Poaceae and Polygonaceae (Miller and McKenzie, 1967; Ben-Dov et al., 2011).
