Polycentropus species indetrminate
Tanida (1997b)
Iwata (1927a, 1927b) recorded a European species Polycentropus flavomaculatus Pictet based on only larval specimens from Honshu and Kyushu. However, Tsuda (1942) proposed that the name should not be used for Japanese fauna because adults of this species had never been found from Japan.
Tanida (1997b) recorded an unnamed species probably belonging to this genus from Okinawa-jima, however, neither generic nor specific status of this 'species' is clear.
