Mesochorinae is a relatively small but widely distributed subfamily of Ichneumonidae, with most species occurring in the Neotropical Region. Currently, there are two classifications in use regarding mesochorine genera, causing numerous taxonomic conflicts. To resolve nomenclature conflicts, seven new replacement names and twelve new combinations are proposed for species now recognized as members of Mesochorus Gravenhorst. Herein the synonymy of Plectochorus Uchida and Stictopisthus Thomson with the genus Mesochorus s. lat. is reaffirmed, supported by the following shared character states: transverse subantennal carina partially or completely developed; supraclypeal area evenly convex, without median protrusion; clypeus not separated from supraclypeal area by depression or groove; and hind wing without vein Cu1b. An updated key to the World genera of Mesochorinae is also presented.
中褶姬蜂亚科是姬蜂科中一个相对较小但分布广泛的亚科，大多数物种分布在新热带地区。目前，关于中褶姬蜂属有两种分类方法在使用，这导致了众多分类学上的冲突。为解决命名冲突，针对目前被确认为中褶姬蜂属（Mesochorus Gravenhorst）成员的物种，提出了七个新的替代名称和十二个新组合。在此，内田褶姬蜂属（Plectochorus Uchida）和汤姆森褶姬蜂属（Stictopisthus Thomson）与广义的中褶姬蜂属同义关系得到重新确认，以下共同特征状态支持这一观点：触角下横隆线部分或完全发育；唇基上方区域均匀隆起，无中央突出；唇基与唇基上方区域未被凹陷或沟槽隔开；后翅无Cu1b脉。此外还给出了一份更新后的世界中褶姬蜂亚科属的检索表。
