Resumen:
The eulophid Aprostocetus (Ootetrastichus) infulatus
(De Santis) has been previously known only from a single female holotype from
Buenos Aires Province in Argentina. We obtained a series of specimens of this
species using sentinel eggs of different species of Cicadellidae and
Delphacidae, exposed in cornfields near El Manantial and San Miguel de Tucumán,
in Tucumán Province, Argentina. The previously unknown male of A. (O.) infulatus is described and
illustrated. For the first time, information on the host associations of this
species is provided while its known distribution range is expanded to northern
Argentina. This eulophid is an economically significant species in Argentina,
where its hosts include two well-known vectors of corn diseases, the leafhopper
Dalbulus maidis (DeLong &
Wolcott) and the planthopper Peregrinus
maidis (Ashmead).
