New braconid species of the Euphorinae genus Syntretus Foerster and a first report of the Alysiinae genus Heratemis Walker from India

The species of the genus Syntretus Foerster (Hymenoptera: Braconidae: Euphorinae) are known to be Parasitic on adult Ichneumonidae (Cole, 1959) and Apidae (Bombinae) (Alford, 1968). The genus is Afrotropical, Holarctic, Neotropical, and Oriental in distribution, and is known from India by a recently described species, Syntretus curvatus Gupta, van Achterberg & Pattar, 2023 (Gupta et al., 2023). A second species from India is described and illustrated.The genus Heratemis Walker (Hymenoptera: Braconidae: Alysiinae) is known the Afrotropical region, Australasian, Neotropical, Oceanic and the Oriental regions, and is reported for the first time from north-eastern and southern regions of India.Syntretus specimens were collected from Malaise traps in Karnataka (southern India), and Heratemis specimens from Arunachal Pradesh and Tamil Nadu, India using a sweep net. The following abbreviations are used in the descriptions: POL—Posterior Ocellar Line; OOL—Ocular Ocellar Line; OD—Ocellar Diameter. Morphological terminology in general follows van Achterberg (1993). Photos were taken with a Leica M 205 A stereozoom microscope with Leica DC 420 inbuilt camera using Automontage software (version 3.8). The specimens are deposited in the National Insect Museum (NIM) of ICAR-National Bureau of Agricultural Insect Resources (ICAR-NBAIR), Bengaluru, India.
