A review of the subfamily amblyseiinae Muma (Acari: Phytoseiidae): Part V. tribe Amblyseiini, subtribe Proprioseiopsina Chant and McMurtry

“…We suggest that these are homoplastic with this form of male process in the genus Neoseiulus Hughes in the tribe Neoseiulini Chant and McMurtry (2003a) and in the genus Graminaseius Chant and McMurtry in the subtribe Amblyseiina (Chant and McMurtry, 2004a). It occurs with only one species in the subtribe Arrenoseiina (Chant and McMurtry, 2004b), though it is not fully developed, and does not occur at all in the subtribe Amblyseiina other than with the genus Graminaseius. This T-shaped process perhaps is not associated with any particular spermathecal morphology in the Proprioseiopsina, although the females of most species with the process T-shaped have the calyx saccular.…”

“…Diagnosis -The species in the subtribe Proprioseiopsina are characterized above all by the absence of seta J2, though this is not an infallible distinction (see the pusillus species group in the genus Amblyseius in the subtribe Amblyseiina (Chant and McMurtry, 2004a) and all but one species in the genus Phytoscutus in the subtribe Arrenoseiina (Chant and McMurtry, 2004b)). There is a variety of idiosomal setal patterns with the following dorsal setae present/absent: j5, Z1, $2, $4.…”

“…There is overlap in these character states between the 2 subtribes but the extremes in length/width ratios of the ventral shields and their degrees of reticulation are far more marked in the Arrenoseiina than in the Proprioseiopsina. Also, the presence of extensive ectal strips on some species in Proprioseiopsis is also a striking homoplasy with the ectal strip that is universal in the genus Arrenoseius in the subtribe Arrenoseiina (Chant and McMurtry, 2004b). JV-3:ZV, with only 28 pairs of setae), one of the most hypotrichous species in the subfamily.…”

“…In a later paper (Chant and McMurtry, 2004b) we reviewed the subtribe Arrenoseiina. The present paper deals with the third subtribe, the Proprioseiopsina.…”
