Simple Summary
The Oriental genus Caloapenesia (Hymenoptera: Bethylidae), belonging to Pristocerinae, is reported from China for the first time. The new species, Caloapenesia xui sp. nov., is described based on morphological comparisons. An updated key to all species of Caloapenesia is provided. The diagnostic characters used for species identification and the geographic distribution of this genus are discussed.
Abstract
The genus Caloapenesia, only known from the Oriental region, comprises nineteen species, seventeen of which are recorded from Thailand and the Philippines, countries adjacent to China. During our examination of bethylid specimens from southern China, we discovered Caloapenesia xui sp. nov. from Guangdong Province, representing the northernmost record for the genus. The new species is described and illustrated, and an updated key to the males of Caloapenesia is provided.
