Two new sibling species of <i>Gryon</i> Haliday (Hymenoptera, Scelionidae), egg parasites of blood-sucking Reduviidae (Heteroptera)

Abstract

Abstract Two species of Gryon Haliday, parasites on eggs of blood-sucking Reduviids, are described, namely G. triatomae sp.n. from Singapore and India, reared from eggs of Triatoma rubrofasciata (De Geer) and Linshcosteus sp., and G. linshcostei sp.n. from India from eggs of Linshcosteus sp. The species differ in biological attributes but are not separable by morphology; with G. insularis (Ashmead) they form the insularis -group.
