Ecology. Found under wet wood and in litter in deciduous forest.
Etymology. Named after the type locality, Zhejiang Province, China.
Discussion. The new species, Papirioides zhejiangensis , is most close to the Indonesian species P. tonsori in the circumanal and dens setae. However, it differs from the latter in the facial setal pattern, length of dorsal club on the great abdomen, and number of short spines on the club. It is very similar to another Indonesian species P. jacobsoni in the color pattern. However, it is readily distinguished from the latter by the facial setal pattern, length of dorsal club on the great abdomen, circumanal setae and other features. The comparison of the new species with the three species in the genus with dorsal club on the great abdomen is shown in the following table. The Japanese species P. uenoi is excluded from the table since it was poorly described. However, the new species is also easily separated from it by the absence of two dorsal brown stripes on great abdomen and the dens with setae mostly serrate rather than smooth or weakly serrate as in the latter.
