Diagnosis.

This species is exteriorly similar to M. sistrata ( Meyrick, 1916) , and M. iriomotensis Robinson 1986 , but can be distinguished by the following characteristics: the row of cornuti on the vesica are broad on posteriorly and narrow on anteriorly (broad all over M. iriomotensis , and M. sistrata ); the lamella antevaginalis is basally triangular (rounded in M. iriomotensis ).

Description.

(Figs 4 View Figures 1–4 , 12–15 View Figures 12–15 , 17 View Figures 16, 17 , 23 View Figures 18–23 ) Measurement. Forewing length 9.3–9.5 (n = 2) in males, 9.7–10.6 mm (n = 3). Antennae length 4.7–5.0 mm (n = 2) in males, 5.0– 5.2 mm (n = 2) in females.

Wingspan 20.2–20.5 mm (n = 2) in males, 21.5–23.2 mm (n = 2) in females in Ogasawara Islands, 18.0 mm in male, 16.0 mm in female in original description.

Biology.

Larvae feed on Ganoderma lucidum (Leyss. ex. Fr.) Karst, G. tsunodae (Yasuda) , G. sinense Zhao, Hsu & Zhang ( Ganodermataceae ), and Inonotus mikadoi (Lloyd) Gilbertson & Ryvarden ( Polyporaceae ) (Oasda et al. 2016; Xu et al. 2022). On the Ogasawara Islands, larvae feed on Polyporaceae white fungi. Adults were collected in June and July from the Ogasawara Islands, in July from Honshu, Japan ( Sakai 2013), and in April and July from Taiwan ( Robinson 1986).

Distribution.

Japan (Honshu, Chichijima Is., Ototojima Is., Mukojima Is., Nakodojima Is.) Korea, China, and Taiwan).

DNA barcoding.

Three DNA barcodes from females were generated and deposited in the DDBJ (accession numbers: LC 832853 View Materials , LC 832849 View Materials , and LC 832850 View Materials ). The sequences of Ogasawara Islands were completely matched (n = 3), and intraspecific pairwise distances of this species between Ogasawara Island specimens and Honshu ( LC 260333 View Materials ) and Chinese specimens (OR 793908, OL 639142 View Materials , OL 639141 View Materials ), were 0.76–1.38 % (n = 7) (Table 2 View Table 2 ).
