Remarks. Ischnosoma bolitobioides , originally described from Japan ( Bernhauer, 1923) and subsequently recorded from Taiwan ( Cameron, 1949), was recently recorded also from mainland China (Fujian, Sichuan) and Thailand by Kocian (2003). The records presented above suggest that the species is widely distributed in the central and southern parts of mainland China ( Fig. 63 ). The records from Gansu, Hubei, Shaanxi and Yunnan are new province records.
