Genus Zagrammosoma Ashmead, 1904

Diagnosis: Two funiculars on antennae, elongated pronotum; notaulus curved and extending to anterior half of axilla; axilla strongly advanced, typically elongate, mostly anterior to scutellum; mesoscutum elongate, longer than scutellum.Antennae situated at the level of lower margin of the eyes. Propodeum without a median carina or it is weakly developed ( Gordh 1978). Axillae placed in front of the base of mesoscutum and scutellar groove and notauli continued into the scuto-axillar line ( Yefremova 1995a). Forewing often with fuscate areas. Other characteristics were mentioned by Cao et al (2014). Color of body at least partly yellow, not metallic.

Identification: A key to nine Nearctic species of Zagrammosoma was published by Gordh (1978). Three Chinese species were keyed by Cao et al. (2014). The following key includes species of Zagrammosoma in Israel.
