Copidosomopsis Girault,a New Genus to China with Description of a New Species (Hymenoptera:Encyrtidae)

  • Received Date: 2000-03-16
  • Two species of the genus Copidosomopsis Girault are described in this paper,i.e. Copidosomopsis nacoleiae (Eady) collected from Hanoi,Vietnam and Copidosomopsis trisegmentis Xu,sp.nov.collected from Shandong,China.The genus is first recorded from China. 1. Copidosomopsis nacoleiae (Eady) Host: Cnaphalocrocis medinalis Guenee, Nacoleia octasema (Meyr)(Lepidoptera:Pyralidae). Distribution:Vietnam(Hanoi),India,Singapore,Malaysia,Indonesia,Papua New Guinea. Specimen examined:4♀♀,Hanoi,Vietnam,1997-04,Wenlin Fan,ex Cnaphalocrocis medinalis Guenee,C9701-1. 2. Copidosomopsis trisegmentis Xu,sp.nov. Host: Hapsifera barbata (Christoph)(Lepidoptera:Tineidae). Distribution:Shandong(Taian). Type specimen:holotype ♀,Taian(36°12′ N,117°06′ E),Shandong,1972 12,Zhang Zaoyi,ex Hapsefera barbata (Christoph),C7392-1;paratype 4♀♀,same data as holotype. Diagnosis:This new species is similar to Copidosomopsis nacoleiae (Eady,1960),but can be distinguished from the latter by (1)antennal scape 6.0 times as long as wide,longer than first-fifth funicle segments combined,the latter species with scape as long as first-fourth funicle segment combined;(2)clava 3 segments,strongly oblique truncated,the latter clava solid,with apex slightly truncated;(3)fore wing with 8 setae in about two rows,the latter species with 10 setae,in about two rows.
