TRIAPITSYN, Serguei V.; SOSA, Alejandro J.  and  HERNANDEZ, M. Cristina. Egg parasitoids of Megamelus spp. (Hemiptera: Delphacidae) in Argentina tentativa. Rev. Soc. Entomol. Argent. [online]. 2010, vol.69, n.3-4, pp.171-188. ISSN 0373-5680.

Egg parasitoids (Hymenoptera: Eulophidae, Mymaridae, and Platygastridae) of Megamelus spp. (Hemiptera: Delphacidae) in Argentina are reviewed and keyed. Four new species are described: Anagrus (Anagrus) empanadus Triapitsyn, sp. nov. (Mymaridae, parasitoid of M. scutellaris Berg feeding on water hyacinth, Eichhornia crassipes (Martius) Solms-Laubach, Aprostocetus (Ootetrastichus) riverplaticus Triapitsyn, sp. nov. (Eulophidae: Tetrastichinae, parasitoid of M. bellicus Marino de Remes Lenicov & Sosa), A. (Ootetrastichus) yerbamatei Triapitsyn, sp. nov. (parasitoid of M. bellicus, M. scutellaris and Megamelus sp.), all from Buenos Aires Province (A. (Ootetrastichus) yerbamatei also occurs in Formosa Province), and Parascelio sabcli Triapitsyn, sp. nov. (Platygastridae: Scelioninae, parasitoid of M. scutellaris in Formosa, the host association is tentative). Other known egg parasitoids of Megamelus spp. in Argentina include Kalopolynema (Kalopolynema) poema Triapitsyn & Berezovskiy (Mymaridae, parasitoid of M. scutellaris in Buenos Aires), and also Cremastobaeus atratus Loiácono & Mulvani (Platygastridae: Scelioninae, parasitoid of M. scutellaris in Formosa, the host association is tentative).
