Description of endophallic sclerites

Gonoporal piece ( Fig. 3J View Fig ) straight, slender, 0.81 mm in GL; GL/AL 3.96. Ligula ( Fig. 3J View Fig ) short, slightly curved; LL 0.17 mm; LW 0.04 mm; LL/LW 3.88; GL/LL 4.71.

Distribution

Japan (Honshu, Izu Isls. [Oshima, Miyake-jima, Hachijo-jima], Shikoku, Kyushu, Shimo-koshiki-jima, Yakushima).

Remarks

This is the first record of this species from Oshima, Miyake-jima, and Shimo-koshiki-jima. This species is distributed in the northernmost area in the genus, and widely spread. The local variation of the endophallic sclerites was not observed in this study, but the specimens in the Izu Isls. have somewhat darker elytral coloration.
