We surveyed arthropod galls on Toshima and Shikinejima Islands, the Izu Islands, Tokyo, Japan in November 2012 and May 2013 and found 31 sorts of gall, consisting of 20 cecidomyiid, four aphid, three psyllid, two eriophyoid, one tephritid, and one thrips galls. Twenty-eight and 14 sorts of gall were newly recorded from Toshima and Shikinejima Islands, respectively. Among them, the following galls were new to the Izu Islands: leaf-vein gall induced by Trioza machilicola MIYATAKE (Hemiptera: Psylloidea) on Machilus thunbergii (Lauraceae), leaf gall induced by Tuberocephalus sakurae (MATSU­MURA) (Hemiptera: Aphididae) on Prunus speciosa (Rosaceae), leaf gall induced by Eriophyes sp. (Acari: Eriophyidae) on Elaeocarpus.rylvestris var. ellipticus (Elaeocarpaceae), leaf gall induced by Phyllocoptes sp. (Acari: Eriophyidae) on Stachyurus praecox var. matsuzakii (Stachyuraceae), flower bud gall induced by Asphondylia sp. (Diptera Cecidomyiidae) on Hedera rhombea (Araliaceae), leaf gall induced by Aphis clerodendri (MATSUMURA)(Hemiptera: Aphididae) on Clerodendrum trichotomum (Lamiaceae), bud gall induced by Rhopalomyia iwatensis SHINJI (Diptera: Cecidomyiidae) on Artemisia indica var. maximowiczii (Asteraceae), and leaf gall induced by Cryptosiphum artemisiae BUCKTON (Hemiptera: Aphididae) on A. indica var. maximowiczii.
