Abstract
BACKGROUND: Gryon Haliday (Platygastroidea: Scelionidae) is a cosmopolitan genus of egg-parasitoid wasps primarily associated with Heteroptera. NEW INFORMATION: Gryon ancinla Kozlov & Lê is reported for the first time outside of Vietnam, in China and Cambodia, and as an egg parasitoid of the pestiferous leaf-footed bug, Acanthocoris scaber (L.). Gryon ancinla is redescribed based on recently collected specimens and compared to closely related species of Gryon in the region. Gryon clavaerus Kozlov & Lê is treated as a junior synonym and some characters found in the charon species group are discussed.
