Xenos是一个链翅目的属，其成员寄生于真社会性黄蜂，包括黄蜂属Vespa。我们进行了广泛的采样的Strepsipterans在Xenos从黄蜂收集在东亚和线粒体细胞色素c氧化酶亚基I基因序列（652 bp）的基础上进行分子系统发育分析，以调查21个个体的Strepsipterans之间的隐藏的多样性。结合形态学检查的分析表明，这些链翅类代表了两个不同的物种，X。moutoni du Buysson，1903和X.这两个物种的寄主利用模式不同：后者几乎是专属于胡蜂analis和V. similima，而前者是与胡蜂的其他物种。
Xenos is a strepsipteran genus whose members are parasitic to eusocial wasps, including the hornet genus Vespa. We undertook an extensive sampling of strepsipterans in Xenos from hornets collected in East Asia and performed molecular phylogenetic analyses based on mitochondrial cytochrome c oxidase subunit I gene sequences (652 bp) to investigate the cryptic diversity among 21 individuals of strepsipterans. The analyses, accompanied by morphological examination, revealed that these strepsipterans represent two distinct species, X. moutoni du Buysson, 1903 and X. oxyodontes sp. nov. The two species differed in their host-utilization pattern: the latter was almost specific to Vespa analis and V. simillima, whereas the former was associated with other species in Vespa.
