Distribution. Japan (Honshu, Shikoku, Kyushu), Taiwan, India, Korea?.

Remarks. This species is the only member of the kiuhabona group in Japan, and this is the first record of it from Japan.

Netelia kiuhabona was described from Taiwan, and later recorded from India ( Kaur & Jonathan, 1979) and Korea ( Cha & Lee, 1988). However, judging from the figure of male genitalia for kiuhabona in Cha & Lee (1988), at least the figured specimen is not kiuhabona because the apex of the parmere is obliquely truncate ventrally and the strip of minutely papillate cuticle on the median surface of the paramere is present in the figured specimen. Thus, the occurrence of kiuhabona in Korea needs to be confirmed.
