Genus Philopteroides Mey, 2004 Philopterus Nitzsch, 1818: 288 (in partim). Docophorus Nitzsch, 1818: 289 (in partim). Bitrabeculus Uchida, 1948: 317 (in partim). Philopteroides Mey, 2004: 173. Tyranniphilopterus Mey, 2004: 182 (in partim). Type species Philopteroides novaezelandiae Mey, 2004: 174, by original designation. 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).
