Halticorcus hiranoi (Takizawa, 1982)

Fig. 8 P – T

Host plant.

Aspleniaceae : Asplenium antiquum Makino ; Polypodiaceae : Pyrrosia lingua , Lemmaphyllum microphyllum , Lepisorus thunbergianus , Leptochilus neopothifolius , Loxogramme salicifolia ; Vittariaceae : Vittaria flexuosa Fee.

Leaf mine.

Upper-layer linear-blotch mine on mature leaf (Fig. 8 Q, S, T ). Frass is thread-like, thin, and often intermittent, and deposited along meandering larval trajectory. The fully grown larva exits the mined leaf, falls to the ground, and pupates underground.

Material examined.

• 1 adult and several leaf mines, Inohae , Nichinan, Miyazaki Pref., 20-V-2015 on Loxogramme salicifolia (Fig. 8 P, Q ) ; • 3 adults, Mt. Yuwan , Uken, Amami-ôshima Is., Kagoshima Pref., 8-III-2000 (as larva on Pyrrosia lingua ), emerged on 14–18-V-2000 (Fig. 8 R – T ) ; • 1 adults, Mt. Yuwan , Uken, Amami-ôshima Is., Kagoshima Pref., 16-II-1999 (as larva on Lepisorus thunbergianus ), emerged on 22-IV-1999 ; • 4 adult, Mt. Yuwan , Uken, Amami-ôshima Is., Kagoshima Pref., 7-III-2004 (as larva on Asplenium antiquum ), emerged on 25-V – 5-VI-2004 ; • 2 adults, Mt. Katsuu-dake , Nago, Okinawa Pref., 23-XII-1989 (as larva on Lemmaphyllum microphyllum ), emerged on? - III- 1990 ; • 1 adult, Inokawa-dake , Tokunoshima Is., Kagoshima Pref., 12-III-2001 (as larva on Vittaria flexuosa ), emerged on 25-VI-2001 ; 8 adults, Kuroshima Is. , Mishima-mura, Kagoshima Pref., 11-III-1995 (as larva on Vittaria flexuosa ), emerged on 21–25-V-1995 .
