Remarks. This species was first described by Wu (1984) based on specimens collected from Mt. Jiuhuashan, Anhui province, China. Later, Hendricks and Kosztarab (1999) redescribed the species based on specimens collected from Japan. The material seen during this study included specimens from the same collection as the holotype and are undoubtedly conspecific with those seen by Wu (1984), but they differ from those described by Hendricks and Kosztarab (1999). The specimens of P. jiuhuaensis from China have multilocular disc tpores ventrally on the last abdominal segments and have bag-like metathoracic legs 3.2–4.0 times larger than the spiracles, whereas, according to Hendricks and Kosztarab (1999), the specimens from Japan lack multilocular pores ventrally on the posterior abdominal segments and the bag-like metathoracic legs are only about 2.5 times larger than the spiracles. The species from Japan described by Hendricks and Kosztarab (1999) is therefore considered to be different from P. jiuhuaensis and should be considered as a new species. As this latter species is not known from China, it is not considered further here.
