Hosts and biology.

Feeding on intermediate instar larvae of Prochoerodes marciana feeding on Prunus annularis ( Rosaceae ), and Sicya medangula feeding on Crossopetalum parviflorum ( Celastraceae ) (both hosts are Geometridae ), parasitoid cocoons stuck to dead larva and substrate.

Distribution.

Costa Rica (Guanacaste Province).
