Identity of parasitoid wasps (Hymenoptera, Braconidae and Eulophidae) reared from aquatic leaf-mining flies (Diptera, Ephydridae) on invasive Brazilian waterweed Egeria densa in South Africa

The Brazilian waterweed, Egeria densa Planchon, 1849 (Hydrocharitaceae), is an invasive species in South Africa where it a host plant for the aquatic leaf-miner Hydrellia egeriae Rodrigues-Júnior, 2015 (Ephydridae, Diptera). Efficacy of biocontrol agent can potentially be affected by parasitoids. Three braconid parasitoid wasps were reared from puparia . By comparison with type specimens, these have been determined to Ademon lagarosiphonae van Achterberg, 2012 (Braconidae: Opiinae), Chaenusa anervata and seminervata Alysiinae: Dacnusini), all previously recorded as parasitoids ephydrid dipterous leaf-miner, lagarosiphon Deeming, 2012, on Lagarosiphon major (Ridley, 1886) Moss ex Wager (Hydrocharitaceae) Africa. chalcidoid, Janicharis africanus Gumovsky & Delvare, 2006 (Eulophidae), was also possibly hyperparasitoid braconids. new country record J.
