最近几次对假定的多面手寄生虫物种的重新评估揭示了隐藏的物种复合体，每个物种的宿主范围都相当狭窄。寄生黄蜂攻击植物上形成瘿的昆虫，它们的生活史策略被认为是促进专业化的，尽管许多物种确实高度专业化，但其他物种被描述为通才寄生虫。Ormyrus labotusWalker（膜翅目：ormilae）就是这样一个明显的多面手，其饲养记录跨越了超过65个与多种橡树物种和植物组织相关的寄主瘿。我们将分子方法与来自广泛地理样本的形态学、宿主生态学和物候数据相结合，以检验这种所谓的通才实际上是几个更专门的物种的复合体的假设。我们在形态学种o中发现了16-18个假定种。虽然我们没有发现单一的统一的专业化轴线，但每个工蜂只从1-6个宿主瘿类型中饲养。我们还在另外两种已命名的狐猴物种中发现了隐栖专家。我们的研究表明，在考虑仅由形态特征描述的寄生昆虫的寄主范围时应谨慎，特别是考虑到它们作为生物防治生物的重要性及其在生物多样性和进化研究中的作用。
Several recent reappraisals of supposed generalist parasite species have revealed hidden complexes of species, each with considerably narrower host ranges. Parasitic wasps that attack gall-forming insects on plants have life history strategies that are thought to promote specialization, and though many species are indeed highly specialized, others have been described as generalist parasites.Ormyrus labotusWalker (Hymenoptera: Ormyridae) is one such apparent generalist, with rearing records spanning more than 65 host galls associated with a diverse set of oak tree species and plant tissues. We pair a molecular approach with morphology, host ecology, and phenological data from across a wide geographic sample to test the hypothesis that this supposed generalist is actually a complex of several more specialized species. We find 16–18 putative species within the morphological speciesO. labotus, each reared from only 1–6 host gall types, though we identify no single unifying axis of specialization. We also find cryptic habitat specialists within two other namedOrmyrusspecies. Our study suggests that caution should be applied when considering host ranges of parasitic insects described solely by morphological traits, particularly given their importance as biocontrol organisms and their role in biodiversity and evolutionary studies.
