Distribution. Palaearctic: Algeria (Lucas 1871), Turkey and Araxes Valley (Bouček 1952) [under E. nuda ] and Israel (Bouček 1956). Euchalcis unicolor represents a new genus and species for the Iranian fauna.

Hosts. E. unicolor was reared in Iran from Amicta sericata Hättenschwiler & Alemansoor ( Lepidoptera , Psychidae ) on Zygophyllum atriplicoides F.E.L. v. Fischer & C.A. Meyer ( Zygophyllaceae ), a new host record. This is the second record from a Psychidae . The species therefore might be a specialist parasitoid of that family.
