Remarks

Bitrabeculus kayanobori was placed in Philopteroides by Mey (2004), without justification. The original description and illustration of this species was based on a single male and single female ( Uchida 1948), and fits with the description of the genus Philopteroides , except that the illustration indicates three temporal macrosetae on each side, whereas other species of Philopteroides only have two temporal macrosetae on each side. If correct, this character separates Ph. kayanobori from all other known species of Philopteroides .

We examined two female Philopteroides from the mainland host subspecies Spizixos semitorques semitorques Swinhoe, 1861. These specimens were reported as Po. kayanobori by Chu et al. (2019); however, these specimens do not have ps on abdominal segment III, as in the original illustrations of this species. Moreover, both specimens have only two temporal macrosetae on each side. As Uchida (1948) only illustrated the male, and both our specimens are female, we cannot presently confirm whether these specimens are conspecific with Po. kayanobori .
