Rhinoseius antioquiensis Fain & Hyland 1980

<i>Rhinoseius</i> cf. <i>antioquiensis</i> Fain & Hyland, 1980 <p>(Figs. 19–23)</p> <p> In five species of <i>Rhinoseius</i> some dorsal setae in the anterior part of the male opisthonotal shield are strongly modified, thick and spine-like: <i>R</i>. <i>richardsoni</i> Hunter, 1972, <i>R</i>. <i>panamensis</i> Fain <i>et al</i>., 1977, <i>R</i>. <i>antioquiensis</i> Fain & Hyland, 1980, <i>R</i>. <i>rafinskii</i> Micherdzinski & Lukoschus, 1980 and <i>R</i>. <i>nadachowskyi</i> Wiese & Fain, 1993. While in <i>R</i>. <i>nadachowskyi</i> and <i>R</i>. <i>rafinskii</i> these setae are multiple (3 pairs in <i>R</i>. <i>rafinskii</i> and 5 pairs in <i>R</i>. <i>nadachowskyi</i>), in the remaining species only two pairs (<i>J1</i> and <i>Z1</i>) are modified. Naskrecki & Colwell, (1998) synonymized <i>R</i>. <i>panamensis</i> with <i>R</i>. <i>richardsoni</i>. They discussed the variability of the male opisthonotal and opisthoventral setae and consider <i>R</i>. <i>panamensis</i> to be the heteromorphic form of <i>R</i>. <i>panamensis</i>, in which these setae are setiform. According to these authors, <i>R</i>. <i>richardsoni</i> differs from <i>R</i>. <i>antioquiensis</i> mainly by the absence of setae <i>z1</i>, the thick opisthonotal setae <i>Z5</i> and shorter peritreme, extending anteriorly to the level of <i>z2</i> or <i>z4</i>.</p> <p> Our specimen represents an intermediate form between <i>R</i>. <i>richardsoni</i> and <i>R</i>. <i>antioquiensis</i>, having setae <i>Z5</i> and <i>S5</i> spine-like rather than flageliform, and the peritreme reaching the level of <i>z2</i>. However, the presence of setae z1, and short dorsal propodosomal setae lead us to the conclusion that our specimen is assignable to <i>R</i>. <i>antioquiensis</i> rather than <i>R</i>. <i>richardsoni</i>. We believe that the differences are those of homo- and heteromorphism common in males of these mites.</p> <p> Fain & Hyland (1980) collected <i>R</i>. <i>antioquiensis</i> on the head feathers of the Colombian hummingbirds <i>Chalybura urochrysia</i>, <i>Androdon aequatorialis</i> Gould, 1863 and <i>Phaethornis guy</i>.
