Anagrus Haliday is a large genus of Mymaridae (Hymenoptera), which now includes eight species recorded from Brazil. This new species attacks eggs of damselflies (Odonata: Zygoptera).1 aTriapitsyn, Serguei, V1 aQuerino, Ranyse, B1 aFeitosa, Malu, C B  uhttps://odonatas.myspecies.info/node/2801422nas a2200133   4500008004100000245016600041210006900207300001100276490000700287520090900294100002301203700001801226856004401244       2009                        eng d00aAn aquatic microhymenopterous egg-parasitoid of Argia insipida Hagen in Selys (Odonata: Coenagrionidae) and biological observations in the Central Amazon, Brazil0 aaquatic microhymenopterous eggparasitoid of Argia insipida Hagen  a346-510 v383 aThe tritrophic interaction Argia insipida Hagen in Selys, the Trichogrammatidae egg parasitoid Pseudoligosita longifrangiata (Viggiani) and the host plant Tonina fluviatilis (Eriocaulacea), which is a substrate for egg deposition of A.insipid, was investigated. The study locality was a stream with rapids where macrophytes such as T. fluviatilis grow. Information on aquatic egg parasitoids is scarce. This is the first record of egg parasitism of A. insipida by P. longifrangiata in Brazil, and the first record of occurrence of P. longifrangiata in the country. Parasitized and unparasitized eggs of A. insipida were observed only on leaves 0-5 cm below the water surface. The maximum number of pairs of A. insipida laying eggs in the study area was observed between 13:00 h and 14:00 h. Leaves of T. fluviatilis become yellowish and dry out when large numbers of eggs of A. insipida are laid on them.1 aQuerino, Ranyse, B1 aHamada, Neusa  uhttps://odonatas.myspecies.info/node/11
