The P. chinensis -group

Pale or bright yellow species. Ninth abdominal segment narrow, moderately rounded anteriorly. Apical lobe on posterolateral margin absent or only slightly developed; dorsum very narrow. Basal segment of clasper geniculate except in P. pallidipennis . Tenth tergum long with pair of slightly upcurving ventrocaudal hooks. Setose warts situated at very top of tergum forming a very prominent pair of blunt and obtuse lobes. (In P. chekiangensis these lobes dominate the tenth tergum and the ventrocaudal hooks are absent). Six species, P. chekiangensis , P. chinensis , P. dentifera , P. dryope , P. pallidipennis and P. periboia comprise this group, which is distributed over north and south China, Japan and southeastern Asia.
