Abstract

Two new species of Trigonalyidae are described from Tibet (SW China): Jezonogonalos nyingchiensis Chen & van Achterberg, sp. nov., and Taeniogonalos eurysoma Chen & van Achterberg, sp. nov. In total, seven species representing four genera are known from Tibet, and two of them are newly recorded from Tibet: Taeniogonalos bucarinata Chen, van Achterberg, He & Xu, 2014, and Teranishia crenulata Chen, van Achterberg, He & Xu, 2014.

Highlights

Trigonalyidae is a small family of Hymenoptera in its own superfamily Trigonalyoidea, with approximately 120 recognized species in 16 genera worldwide (Carmean and Kimsey 1998; Smith and Stocks 2005; Santos et al 2012; Smith and Tripotin 2012; Smith et al 2012; Chen et al 2014; Yamane 2014; Smith and Tripotin 2015; Tan et al 2017; Lelej 2019)
Once inside the caterpillars or sawfly larvae, the wasp egg either hatches and attacks any other parasitoid larvae or it waits until the caterpillars or sawfly larvae are fed to a Vespidae larva, which it attacks
