A new species of Horismenus Walker, H. saturnus Schoeninger & Hansson (Hymenoptera: Eulophidae), is described from material reared from eggs of an unidentified species of Saturniidae (Lepidoptera). The new species is compared to H. cupreus (Ashmead, 1894), a species it is very similar to, and to H. ancillus (Brèthes), a species with the same type of host as H. saturnus. A total of 30 adult specimens developed from the eggs of Saturniidae. This is the second record of a Horismenus species parasitizing eggs of Saturniidae and the first record of this host from Brazil. Here, we provide a diagnosis and description of the new species including morphological and molecular characters, and multiple illustrations.
一种新的 Horismenus 物种，即 Saturniidae（鳞翅目）未鉴定物种卵寄生的 Horismenus saturnus Schoeninger & Hansson（膜翅目：长尾小蜂科）被描述。该新种与非常相似的 H. cupreus（Ashmead，1894）以及与 H. ancillus（Brèthes）进行了比较，H. ancillus 是与 H. saturnus 具有相同宿主类型的物种。总共从 Saturniidae 的卵中发育出 30 个成虫标本。这是 Horismenus 物种寄生 Saturniidae 卵的第二个记录，也是巴西首次记录到这种宿主。在这里，我们提供了新物种的诊断和描述，包括形态和分子特征以及多个插图。
