Type species Gamasus plumifer Canestrini & Fanzago, 1876: 130 , designated by Vitzthum, 1941 . Phytoseius ( Dubininellus ) Wainstein, 1959: 1361 . Type species Phytoseius ( Dubininellus ) corniger Wainstein, 1959: 1361 , by original designation. horridus species group Denmark , 1966: 83 . purseglovei species group Chant & Yoshida-Shaul, 1992: 12 . Type species: Phytoseius horridus Ribaga, 1904 , sensu Athias-Henriot, 1957 . Chant & McMurtry (1994) recognised three species groups based on presence or absence of setae J2 and R 1 : the horridus species group, Denmark (1966) with setae J2 and R 1 absent, the pulmifer species group Chant & Yoshida-Shaul (1992) characterised with setae J2 and R 1 present and purseglovei species group Chant & Yoshida-Shaul (1992) with absence of seta J2 and presence of seta R 1 . Type species: Phytoseius purseglovei De Leon, 1965 . Following the classificatory scheme of Chant & McMurtry (1994) , Phytoseius birbikrami sp. nov. belongs to the purseglovei species group by having female idiosomal setal pattern 12A:4A/JV3,4: ZV, setae z3 , s6 , R1 , JV2 , ZV3 are present. Type species: Phytoseius horridus Ribaga, 1904 , sensu Athias-Henriot, 1957 . The species P . khowaiensis sp. nov. and P . baramuracus sp. nov. belong to horridus species group with setae J2 and R1 absent, ventral setal pattern JV-3,4: ZV ( Chant & McMurtry 1994 ).
