Host plant.

Rubiaceae : Coptosapelta diffusa (Champ. ex Benth.) , Gardenia jasminoides , Randia canthioides Champ. ex Benth , Tarenna gracilipes Ohwi.

Leaf mine.

Upper-layer linear-blotch, often radiate mine on mature leaf (Fig. 21 J – K, N – O ). The mine often has blind ends and branches. The larva sometimes relocates its mine. Frass is granular, often discharged outside from slit made by the larva. The fully grown larva pupates in a pupation site in the mine along the midrib, where upper layer of the leaf is kept intact and green (Fig. 21 O ).

Material examined.

• 1 adult, Mt. Nekumachiji , Ôgimi, Okinawa Is. Okinawa Pref., 30-III-2018 (as larva on Tarenna gracilipes ), emerged on 2-V-2018 (Fig. 21 G – J ) ; • 1 adult, Mt. Nishime , Kunigami, Okinawa Is., Okinawa Pref., 22-XII-1989 (as larva on Gardenia jasminoides ), emerged on? - IV- 1990 ; • 2 leaf mines, Yona , Kunigami, Okinawa Is., Okinawa Pref., 29-III-2019 on Coptosapelta diffusa (Fig. 21 K ) ; • 2 adults, Yona , Kunigami, Okinawa Is., Okinawa Pref., 29-III-2018 (as larva on Randia canthioides ), emerged on 3-V-2018 (Fig. 21 L – O ) .
