Introduction P.B.No.2491, H.A. Farm Post, Over 8,300 species of inhabiting terrestrial and marine environment had been recorded Hebbal, Bengaluru - 560024, Karnataka, India from the Andaman and Nicobar Islands including around 1117 species and subspecies of endemics. Among them, 186 species of Hymenoptera were reported [22]. Insect diversity and K Veenakumari their ecological significance of the proposed City forest in Andaman and Nicobar Islands have Division of Insect Systematics, been studied [26]. Recently, little research works on encyrtids, aphelinids [6, 7, 8, 9], platygastrids ICAR-National Bureau of [28] and braconids [1] from Andaman and Nicobar Islands were reported. In respect of Agricultural Insect Resources [15] P.B.No.2491, H.A. Farm Post, mymaridae, Manickavasagam and Rameshkumar were the first to record six genera and 15 Hebbal, Bengaluru - 560024, species of mymarids from the Andaman and Nicobar Islands followed by Zeya [29] (one new Karnataka, India species of Tanyxiphium); Anwar et al. [2] (two new species of Omyomymar); Palanivel et al. [18] (one new species of Stephanocampta) and Rameshkumar and Manickavasagam [19] (two new species of Dicopomorpha). This paper adds nine more species to the mymarid fauna of the

Andaman and Nicobar Islands from among which Dicopomorpha zebra Huber is recorded for the first time from India.

2. Materials and method Mymarid parasitoids were collected from different localities of Andaman and Nicobar Islands during March 2016 using yellow pan traps and net sweeping from various ecosystems (grassy [16] land, weedy field, Orchard etc.) . Collected specimens were processed with [3] Hexamethydisilazane (HMDS) and card/slide mounted for identification. The species of mymarids were identified by appropriate literature [5, 10, 11, 12, 23, 24, 26, 27]. Voucher specimens were deposited in the repository of ICAR – National Bureau of Agricultural Insect Resources (ICAR-NBAIR), Bengaluru, India.

3. Results and Discussion Survey of Andaman and Nicobar Islands revealed that Dicopomorpha zebra Huber (Hymenoptera: Chalcidoidea: Mymaridae) is reported from India for the first time. Nine Correspondence species of mymarids are recorded as new to Andaman and Nicobar Islands. An updated Rameshkumar A checklist of mymarids is also provided. (A). Division of Insect
