Type material examined.

Paratype, male (pinned, wing slide-mounted), China, Formosa [Taiwan], Koshun, 25 April - 25 May 1918, J. Sonan, K. Miyake, M. Yoshino leg. (USNM).

Other examined material.

China, 2 males, 1 female (pinned), Formosa [Taiwan], Koshun, 25 April - 25 May 1918, J. Sonan, K. Miyake, M. Yoshino leg. (NHMUK) (Fig. 54 ) ; 1 male (pinned), Formosa [Taiwan], [Kaohsiung County - label in Chinese] (NHMUK) .

Remark.

The first record of this species from Korea is that of Kim (1971). Unfortunately, no information was listed on which specimen(s) that record had been made, but the illustration (fig. 36) shows a species which is different from H. lygropis (Fig. 55 ). The most obvious difference is the missing cell m1, while H. lygropis has a well-developed cell m1. The Korean University collection, on which Kim’s (1971) publication was based, has a few Hexatoma specimens identified as H. lygropis , but all of them are in fact H. pernigrina , which also has no cell m1. All other records of that species are based only on Kim (1971). Based on this, we exclude H. lygropis from the Korean species list. Hexatoma lygropis is endemic to Taiwan.
