It is a solitary endo-parasitoid in egg of the spotted lanternfly, Lycorma delicatula （White） （Homoptera： Fulgoridae）, which causes damages to many ornamental and fruit trees in China. The brief biology of the new parasitoid is also mentioned. The new species has high potential as a biocontrol agent for suppression of the pest because of its parasitism rates of egg masses 30.4% and of eggs 40.2% respectively with sex ratio of female to male 1.9：1.0, as well as the relative easiness for mass rearing. The detailed feature characters and photos of the new species are supplied. Meanwhile, a key to distinguish the present new species from the other close two （A. japonicus and A. bifasciatus） in the genus is provided. Type specimens are deposited in the Insect Museum, Chinese Academy of Forestry, Beijing, China.展开更多

A key to the species of the genus is provided. The new species is similar to the Indian species I. trimaculatus （Cameron, 1900） structurally, but differs for example by： basal half of pterostigma yellow; apical half dark brown; smooth postero-lateral area of the third tergite rather small; propodeum with belt of setae dorsally and lamelliform carinae posteriorly; ovipositor sheath approximately 0.60 times the forewing, somewhat longer than metasoma; the first tergite surface distinctly carinate and rugose, especially in its medial area and laterally. The type specimens are deposited in the Beneficial Insects Lab, College of Plant Protection, Fujian Agriculture ＆ Forestry University, China.展开更多
