报道了广东广州新记录种Diomusguilavoguii Duverger，1994。吉氏粉蚧幼虫与一种侵入性粉蚧Paracoccusmarginatus威廉姆斯& Granara de Willink，1992一起被收集，该粉蚧侵染番木瓜、木薯和几种观赏植物。然而，人们对吉氏盾蚧的生物学知之甚少，尤其是其幼虫的形态。Diomusguilavoguii Duverger，1994，原产于非洲几内亚的科纳克里，为广东省首次发现。但目前尚不清楚吉氏盾蚧何时以及如何从非洲传播到广东省广州市。成虫和幼虫都以入侵的粉蚧Paracoccusmarginatus威廉姆斯& Granara de Willink（半翅目，粉蚧亚科）为食，该粉蚧侵染番木瓜和观赏植物。本文对成虫的外部形态和雄性外生殖器进行了重新描述。首次对幼虫和蛹进行了详细描述。讨论了D.guilavoguii和D.hennessyi Fürsch，1987的地位。
Diomusguilavoguii Duverger, 1994, an adventive species, is recorded from Guangzhou (Guangdong Province), China for the first time. Larvae of D.guilavoguii were collected in association with an invasive mealybug, Paracoccusmarginatus Williams & Granara de Willink, 1992, infesting papayas, cassava and several ornamental plants. However, little has been known about the biology of D.guilavoguii, especially the morphology of their larvae since their original descriptions. Diomusguilavoguii Duverger, 1994, native to Conakry, Guinea (Africa), is recorded as established in Guangdong Province for the first time. However, it is unclear when and how D.guilavoguii spread from Africa to Guangzhou, Guangdong Province. Both the adult and larva feed on the invasive mealybug Paracoccusmarginatus Williams & Granara de Willink (Hemiptera, Pseudococcidae) that infests papaya and ornamental plants. In this paper, the external morphology and male genitalia of adults are re-described. The detailed descriptions of larva and pupa are also provided for the first time. The status of D.guilavoguii and D.hennessyi Fürsch, 1987 are discussed.
