Periclista shiritakensis Togashi, 1999

Japanese name: Zuaka-maru-habachi

( Fig. 6C–E )

Material examined. HONSHU: Tochigi Pref.: 1 ♀, Nakagawa, Wami , 36°46'N 140°10'E, coll. larva on Quercus serrata 7. V. 2019, mat. 17. V., em. 10. IV. 2020, S. Ibuki ( Fig. 6C–E ) .

Larva. Final feeding-instar ( Fig. 6C–D ): Yellow green almost entirely; spines completely white; bifurcate spines relatively long, about 1/5 as long as height of trunk; subspiracular lobe with anterior spine bifurcate, posterior spine simple; surpedal lobe with two simple spines. Mature larva ( Fig. 6E ): Yellow green almost entirely, without spines.

Host plant. Fagaceae : Q. serrata (new record).

Remarks. The host plant and larva of P. shiritakensis have been unknown until now.

The larva of this species is similar to the larva of P. erythrogramma in having an entirely yellow green head and trunk, but they are easily distinguished by the color and shape of the spines.
