ABSTRACT This paper is a contribution to the characterisation by an integrated approach of the species Microterys chalcostomus (Dalman), a parasitoid of mealybugs and apparently a predator of kermesid eggs. Until now, the species, whose type is in good condition, could be identified only by the meagre original description by Dalman and subsequent notes by Graham. Nonetheless, it appears to be extremely common in Europe, hence the need for a thorough morphological and molecular characterisation. Systematic notes on closely related species of Microterys parasitoids of mealybugs are included.

Microterys chalcosotmus (Dalman) (膜翅目: Chalcidoidea: Encyrtidae) 的重新描述, 一种与 Phenacoccus aceris (Signoret) (半翅目: Pseudococcidae) 和 Kermes spp. 相关的寄生虫。（半翅目：Kermesidae），对其寄主关系的评论

摘要 本文是对 Microterys chalcostomus (Dalman) 物种的综合方法表征的贡献，它是粉蚧的寄生物，显然是 kermesid 卵的捕食者。到目前为止，该物种的类型状况良好，只能通过 Dalman 的微薄原始描述和 Graham 的后续注释来识别。尽管如此，它在欧洲似乎非常普遍，因此需要进行彻底的形态学和分子表征。包括对粉蚧的 Microterys 寄生蜂的密切相关物种的系统说明。
