Tomato leaf miner, Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae) is a dangerous and difficult pest to manage because of the larval feeding habits, it is attacking all aerial parts of the host (leaves, stems and fruits) cultivated and wild plants with a high preference towards the species of Solanaceae plants especially tomato and other Solanaceous crops in greenhouses and fields. The aim of the study was Survey and Identification of new species of Hymenopteran Parasitoids from Larvae of Tomato Leafminer T .absoluta (Meyrick).The samples of infested tomato plants by Tomato leaf miner T. absoluta were collected from a greenhouse and fields during (March/2019 to August/2021) from Lattakia and Tartus provinces. The species were identified by using specific keys to subfamilies, genera and species, they belong to four different superfamilies: Ceraphronoidea, Chalcidoidea, Chrysidoidea, Platygastroide. And three species and two genera: Aphanogmus clavicornis Thomson, 1858 (Ceraphronoidea: Ceraphronidae) Larval actoparasitoid, Goniozus nephatidis (Muesebeck) (Chrysidoidea:Bethylidae) larval gregarious Ectoparasitoid, Pteromalus sp. Swederus, 1795 (Chalcidoidea: Pteromalidae) larval Ectoparasitoid, Diglyphus isaea (Walker 1838) (Chalcidoidea: Eulophidae) larval gregarious Ectoparasitoid, and genus  Telenomus sp. (Platygastroide: Platygastridae) egg parasitoid. The most widely spread of these species was Diglyphus isaea (95 adults)(75.39%) then genus Pteromalus sp. (9 adults) (7.1%),and Goniozus nephatidis  (6 adults) (4.7%), followed by Telenomus sp. (4 adults) (3,2%), and  Aphanogmus clavicornis )2 adults) (1,6%) These identified species in this paper is the first record of parasitoids on Tomato leafminer larvae T .absoluta (Meyrick)  in Syria

Keywords: Tomato Leafminer, parasitoid, Hymenoptera, Tomato. Syria.
