Abstract

TRIAPITSYN, Serguei V.  and  HERNANDEZ, M. Cristina. Egg parasitoids of Taosa spp. (Hemiptera: Dictyopharidae) in Formosa, Argentina, with descriptions of two new species. Rev. Soc. Entomol. Argent. [online]. 2011, vol.70, n.1-2, pp. 55-61. ISSN 0373-5680.

Egg parasitoids (Hymenoptera: Eulophidae and Platygastridae) of Taosa (Cuernavaca) longula Remes Lenicov (Hemiptera: Dictyopharidae) are reviewed and keyed. This planthopper feeds on water hyacinth, Eichhornia crassipes (Martius) Solms-Laubach, and was collected in Formosa, Argentina, where some of its eggs turned out to be parasitized. Two new species are described: Aprostocetus (Ootetrastichus) taosae Triapitsyn, sp. nov. (Eulophidae: Tetrastichinae) and Telenomus formosanus Triapitsyn, sp. nov. (Platygastridae: Telenominae). The latter species, which belongs to the crassiclava species group of Telenomus Haliday, also attacks eggs of Taosa sp. on Pontederia subovata (Seubert) Lowden. These are first records of egg parasitoids of the genus Taosa Distant.

Keywords : Eulophidae; Aprostocetus (Ootetrastichus); Platygastridae; Telenomus.
