Thanks to Nadine A. Gund and Cipriano Foxi for response, at the moment clear pictures are not available but to clearify it furthermore,the specimen was got from parasitoized mealybug mummy from the hibescus plant in the field, it may be helpful to identify the same.
it appears to be Anagyrus kamali ?: Anagyrus kamali is a parasite with thumbed antannae from China and is being currently used to manage pink mealybug. It has also been recorded in India on mulberry plant. It attacks the mealybugs in two ways. The adult wasp puncturesa mealybug and extracts fluid from the wound. The female wasp feeds on the fluid of the dying mealybug, which provides nutrient to wasp’s eggs for development. The female wasp also lays an egg inside mealybug, which hatches and feeds internally, killing the mealybug. Fully developed adult wasp comes out of the “mummy” of the mealybug by cutting a circular hole in the end of the mummy and crawls out. The process can take place in half the time it takes for the entire life cycle of the mealybug. A. kamali typically has a 15-day life cycle in tropical climates. During its lifetime, a female wasp can lay single eggs inside 40–60 mealybugs.
Dear S.Nakat the specimen is not A.kamali as clear from the morphological characters moreover mostly hymenopterous parasitoids are specie specific and A.kamali usually attack on citrus mealy bug.
It is Marietta leopardina (Aphelinidae) from Pakistan, an hyperparasitoid of Eulophid wasps. It is not Metaphycus nor Anagyrus (Encyrtidae) nor Bethylidae as mentioned by other researchers. Guessing is not a valid criteria in the science of Taxonomy to identify a species.
