This species belongs to the orientalis species group ( Chant and McMurtry 2003b), but according to these authors and Moraes et al. (2007), specimens with shorter setae s4, Z4 and

Z5, and having a distinctly short, thick, spatulate macroseta on genu I belong to the species P. orientalis . This species is widely distributed in tropical and subtropical areas in South America, Africa and Asia. It belongs to a genus included in the large polyphagous generalist group named type III phytoseiid mites ( McMurtry and Croft 1997; McMurtry et al. 2013). Navasero and Navasero (2016) studied the life history of P. orientalis on the broad mite P (. latus ) as prey and reported high predation rates when eggs P of. latus were offered as food, suggesting good potential for the control of this pest. This species was also collected in Mauritius ( Kreiter et al. 2018a; Ferragut and Baumann 2019; Kreiter and Abo-Shnaf 2020b), La Réunion ( Kreiter et al. 2020c) and Vietnam (Kreiter et al. 2020b).

World distribution: Argentina, Brazil, Burundi, India, Japan, Kenya, La Réunion Island, Madagascar Island, Martinique Island, Mauritius Island, Mozambique, Rwanda.

Specimens examined: 3 ♀♀ specimens in total. Coconi, Lycée Agricole (189 m aasl, 12°50 ′ 7 ″ S, 45°8 ′ 11 ″ E), 3 ♀♀ on Capsicum annuum L. ( Solanaceae ), 26/XI/2018.

Remarks: this species was reported by Kreiter et al. (2018a, 2020b, c) and by Ferragut and Baumann (2019) from various places. Morphological and morphometric characters and all measurements fit well with those given by Ferragut and Baumann (2019) and Kreiter et al. (2020b, c). It is described from Asia ( Narayanan et al. 1960) and present in Vietnam (Kreiter et al. 2020b). Paraphytoseius orientalis seems to be more common than P. horrifer in Mauritius Island ( Kreiter and Abo-Shnaf 2020b), whereas the latter is more abundant in Mayotte Island.
