Notes: The false coconut scale, Aspidiotus rigidus Reyne (Hemiptera: Diaspididae), is a serious pest of coconut in the Indonesian and Philippine archipelagos. Field surveys in Viêt Nam in 2015–2018 discovered A. rigidus (a new country record). Also found were three of its primary hymenopteran parasitoids: an unidentified ectoparasitic Aphytis species (Aphelinidae) and two endoparasitoids, The low incidence of A. rigidus in Việt Nam and the presence of the three parasitoid species there suggests that the scale and these parasitoids originated in Indochina.
