Remarks

The species of Philopteroides parasitizing bulbuls appear to form a homogenous group within the Philopteroides mitsusui species group sensu Valim & Palma (2013). In particular, the species known from bulbuls are united by the following characters: Mesosome covers central ⅓ of distal margin of basal apodeme ( Figs 109 , 115 ); parameres curved medianly ( Figs 109–110 , 115–116 ); at least some of sternal plates III–VI reduced in female, with accessory lateral sternal plates (if visible) clearly separated from central sternal plates in at least some segments ( Figs 107 , 113 ). In males of most species, at least sternal plate III is reduced in the same way ( Fig. 106 ), but in Ph. cucphoungensis the central sternal plate may be connected to the accessory lateral sternal plates ( Mey 2004: fig. 23d), and in Ph. holosternus sp. nov. male sternite III is entire ( Fig. 112 ).
