Ambrosia beetles of the (Eichhoff, 1868) species complex are emerging tree pests, responsible for significant damage to orchards and ecosystems around the world. The species complex comprises seven described species, all of which are nearly identical. Given that the morphology-defined species boundaries have been ambiguous, historically, there has been much disagreement on species validity, which was compounded by the presumed loss of the type series of . The species complex was recently reviewed using morphometrics to associate the type specimens to the clades delineated with molecular data under the assumption of the lost type series. We rediscovered a syntype of , and reevaluated the species in the complex using morphometrics. We propose the following taxonomic changes to the species complex: (= (Schedl, 1951); = (Schedl, 1942)) ); (Eggers, 1923) (=. (Schedl, 1951) ); (Gomez and Hulcr, 2018) and (Schedl, 1951) . These taxonomic changes shift the species name associated with the widely used common names for two taxa, namely: should be used for the "Polyphagous Shot Hole Borer", and for the "Tea Shot Hole Borer clade a". A lectotype is designated for in order to stabilize the use of the name.
（艾希霍夫，1868年）物种复合体的食菌小蠹是新出现的树木害虫，对世界各地的果园和生态系统造成了重大破坏。该物种复合体包括七个已描述的物种，它们几乎完全相同。鉴于形态学定义的物种界限一直不明确，历史上对于物种有效性存在很多分歧，而这又因假定的 模式系列的丢失而更加复杂。最近，在假定模式系列丢失的情况下，利用形态测量学对该物种复合体进行了重新审视，以便将模式标本与用分子数据划定的进化枝联系起来。我们重新发现了 的一个合模式标本，并使用形态测量学对该复合体中的物种进行了重新评估。我们对该物种复合体提出以下分类学修订： （= （谢德尔，1951年）； = （谢德尔，1942年））； （埃格斯，1923年）（= （谢德尔，1951年））； （戈麦斯和胡尔克，2018年）以及 （谢德尔，1951年）。这些分类学修订改变了与两个分类单元广泛使用的俗名相关的物种名称，即：“多食性射孔小蠹”应使用 ，“茶射孔小蠹进化枝a”应使用 。为 指定了一个选型，以稳定该名称的使用。
