is a major pest that infects larch plantations over large areas of northern and northeastern China. species are closely associated with ophiostomatoid fungi that are morphologically well-adapted for dispersal by beetles. These associations result in important threat for coniferous forests worldwide. The aim of this study was to characterize the ophiostomatoid communities associated with infesting species and sympatric var. in northeastern China forests. Morphological and multilocus phylogenetic approaches (based on six markers: ITS, LSU, 60S, β-tubulin, EF-1α, and CAL gene regions) allowed identifying 14 species of four genera (, , and ). Eight species are showed to be new to science. Most strains resided in two species complexes, viz. the and the complexes, all together accounting for 76.8% of all isolates. sp. nov., sp. nov., and sp. nov. ( complex) and sp. nov. ( complex) were the four dominant species. The ophiostomatoid communities associated with larch bark beetles, and , in Europe and Asia, China and Japan, also were compared. These comparisons showed distinct, specific assemblage patterns.
是一种主要害虫，在中国北方和东北地区大面积感染落叶松林。该物种与形态上非常适合通过甲虫传播的长喙壳类真菌密切相关。这些关联对全球针叶林构成了重大威胁。本研究的目的是鉴定与中国东北森林中侵害该物种和同域变种的长喙壳类群落。形态学和多位点系统发育方法（基于六个标记：ITS、LSU、60S、β-微管蛋白、EF-1α和CAL基因区域）使我们能够鉴定出四个属（、、和）的14个物种。其中八个物种被证明是新物种。大多数菌株属于两个物种复合体，即复合体和复合体，总共占所有分离株的76.8%。新种、新种和新种（复合体）以及新种（复合体）是四个优势物种。还比较了欧洲和亚洲、中国和日本与落叶松小蠹虫、相关的长喙壳类群落。这些比较显示出不同的、特定的组合模式。
