Alysiinae Leach is a species-rich subfamily in Braconidae, of which several species play an important role in biological control. The monotypic genus Eurymeros tumespiraculum Bhat, 1980 was discovered in Tibet and Yunnan provinces for the first time, representing the first record of the genus Eurymeros Bhat, 1980 (Braconidae, Alysiinae) in China.
The rare genus Eurymeros Bhat, 1980 (Braconidae, Alysiinae) and its only known species, E. tumespiraculum Bhat, 1980, are newly recorded from China. The morphological variation of the Chinese specimens is described and illustrated.
Hymenoptera, Braconidae, Alysiinae, Alysiini, new record, Oriental Region, China
The subfamily Alysiinae (Hymenoptera, Braconidae) is a quite large subfamily in Braconidae, containing over 2450 species worldwide (
The Eurymeros Bhat, 1980 is a small and rare Oriental genus from Alysiini and, so far, was only known from India (
In this paper, we discovered the species E. tumespiraculum in China for the first time and described the variation of the newly-recorded specimens.
The examined specimens were collected by Malaise traps and glued on card points. They are deposited in the the Parasitic Hymenoptera Collection, Institute of Insect Sciences of the Zhejiang University (ZJUH) and in the insect collection of the Fujian Agricultural and Forestry University (FAFU).
For the recognition of the subfamily Alysiinae, see
