Paraphytoseius horrifer , Moraes et al. 1986: 105 , 2004b: 152 ; Chant & McMurtry 2003b: 220, 2007: 53 . Our specimens of Paraphytoseius should be placed the orientalis species group by the absence of setae S5 ( Chant and McMurtry 2003b ). As suggested by Chant and McMurtry (2003b) and Moraes et al. (2007) , we consider that P. horrifer and P. orientalis are different valid species. All our specimens have long setae s4 , Z4 , Z5 , and no distinctly short, thick, spatulate macroseta on genu I. They all belong consequently to the former species. This species is widely distributed in Sub­Saharan Africa and Madagascar . The biology P. horrifer of remains totally unknown. It was mentioned recently for the first time from several countries: La Réunion ( Kreiter et al. 2020d ), Mauritius ( Kreiter and Abo­Shnaf 2020b ), Rodrigues ( Kreiter and Abo­Shnaf 2020a ) Islands and Vietnam ( Kreiter et al. 2020c ). World distribution : Benin , DR Congo , Ghana , India , Kenya , La Réunion Island , Madagascar Island , Malawi , Mozambique , Senegal , South Africa , Uganda . Specimens examined : 36 specimens ( 34 ♀♀ and 2 ♂♂ ) collected during this study. Tsembehou , inside the village ( 446 m aasl, 12°12 27 S , 44°27 54 E ), 34 ♀♀ and 2 ♂♂ on Clerodendrum speciosissimum Van Geert ex Morren (Lamiaceae) , 29/IX/2018 . Remarks : morphological and morphometric characters and all measurements fit well with those mentioned by Kreiter et al. (2020c , d). This species described from Africa ( Pritchard & Baker 1962 ) was first mention in the Indian Ocean from La Réunion Island ( Kreiter et al. 2020d ) but seems to be present in Rodrigues , Mauritius and Mayotte ( Kreiter and Abo­Shnaf 2020a , b; Kreiter et al. 2020a ) and actually in at least one island of Comoros Archipelago. This is the most abundant species in Anjouan Island but all specimens were collected only in one sample site.
