¹ The junior author found many galls of Ceratovacuna sp. formed on Styrax tonkinensis at Nangoa, northern Vietnam, on 11 May 1997.
² We examined a gall of Ceratovacuna sp. collected from Styrax serrulatus by P. W. Fritsch at Ithum Khola River (5000 ft alt.), eastern Nepal, in September 1994.
³ We found some galls of Cerataphis sp. near brasiliensis on Styrax benzoides in Chiang Mai, northern Thailand, on 3 November 2002.
