Most eulophid wasps are primary parasitoids, mainly of endophytic insect larvae (Diptera, Coleoptera, Lepidoptera, Hymenoptera, Hemiptera, and Thysanoptera), but can also attack spider eggs, gall-forming mites, or nematodes. A few species are known to parasitize ants. Here we report on the occurrence of Horismenus floridensis (Schauff and Bouček) attacking Camponotus atriceps (Smith) in southern Mexico (Campeche), expanding the distribution for this eulophid species and the range of its potential hosts. We also provide an updated list of the Horismenus Walker species found in Mexico, which currently includes 21 identified species. This is the second host ant ever recorded for H. floridensis and the first reliable record of C. atriceps as a host for this eulophid wasp. The first host ant reported from Florida 35 years ago was the closely related valid species, C. floridanus (Buckley), erroneously synonymized at that time with C. atriceps (formerly, C. abdominalis (Fabricius)).
大多数长尾小蜂是主要的寄生蜂，主要寄生内寄生昆虫的幼虫（双翅目、鞘翅目、鳞翅目、膜翅目、半翅目和缨翅目），但也可以攻击蜘蛛卵、瘿螨或线虫。少数几种已知会寄生蚂蚁。在这里，我们报告了佛罗里达长尾小蜂（Schauff 和 Bouček）在墨西哥南部（坎佩切）攻击红火蚁（Smith）的情况，扩大了这种长尾小蜂的分布范围及其潜在宿主的范围。我们还提供了在墨西哥发现的 Horismenus Walker 物种的最新清单，其中目前包括 21 种已确定的物种。这是第二个被记录的红火蚁的宿主蚂蚁，也是第一个可靠记录的 C. atriceps 作为这种长尾小蜂的宿主。35 年前在佛罗里达州报告的第一个宿主蚂蚁是密切相关的有效物种 C. floridanus（Buckley），当时错误地与 C. atriceps（以前是 C. abdominalis（Fabricius））同义。
