This paper deals with the description of two new species of Horismenus Walker (Hymenoptera: Eulophidae) from Brazil, parasitoids of larvae of Adetus analis (Haldeman) (Coleoptera: Cerambycidae). Both species are similar to Horismenus steirastomae (Girault), a species that also parasitizes cerambycids. Adetus analis is a pest of Sechium edule (Jacq.) Swartz (Cucurbitaceae), a minor crop in Brazil, Argentina and U.S.A., but also feeds in stems of Pereskia aculeata Miller (Cactaceae), an ornamental plant that has become a problematic weed species in Africa, where it was introduced. The two new Horismenus species are described, diagnosed, and compared to H. steirastomae.
姬小蜂科的霍氏姬小蜂属（Horismenus Walker）两个新物种，它们是臀纹木吉丁（Adetus analis）（鞘翅目：天牛科）幼虫的寄生蜂。这两个物种与同样寄生于天牛科昆虫的斯氏霍氏姬小蜂（Horismenus steirastomae）（吉罗）相似。臀纹木吉丁是佛手瓜（Sechium edule）（杰克）斯沃茨（葫芦科）的害虫，佛手瓜在巴西、阿根廷和美国是次要作物，但它也取食具刺叶仙人掌（Pereskia aculeata）米勒（仙人掌科）的茎，具刺叶仙人掌是一种观赏植物，在被引入的非洲已成为有问题的杂草物种。对这两个霍氏姬小蜂新物种进行了描述、鉴别，并与斯氏霍氏姬小蜂进行了比较。
