The P. flava -group

This group is almost certainly not monophyletic, as the characters that are shared by its members are not demonstrably synapomorphic. Nevertheless it is retained as a convenient grouping with the following characteristics. Medium-sized species. The ninth segment narrow, without apicolateral enlargement, apical lobe on posterolateral margin absent or little developed. Basal segment of clasper sinuate. Tenth tergum with very small hook formation, variable in position. Setose warts located mid-way on tenth tergum, or slightly apically. The thirteen species in this group are P. aureipennis , P. baenzigeri , P. elektra , P. epigona , P. flava , P. fulvescens , P. huberti , P. nuonga , P. ovalis , P. panakeia , P. psamathe , P. renatae and P. straminea ; distributed in central and southeastern Asia and North America.
