RESUMO
A new species of Deinodryinus Perkins, 1907, D. hubeni sp. nov., is described from Ecuador, Tungurahua Province. The new species can be recognized by having the antennal setae shorter than breadth of antennomeres, the face completely sculptured by subparallel longitudinal keels, the paramere with distal extremity covered with sensorial lamellae and with inner proximal branch covered with lamellae and wrapping penis. The male holotype is compared with the known males of all other Neotropical species of the same genus. The key to the Neotropical males of Deinodryinus is modified to include this new species.

Two new species of Anteoninae (Hymenoptera, Chrysidoidea, Dryinidae) are described: Deinodryinus brasiliensissp. nov., from Brazil (Bahia, Minas Gerais and Paraná) and D. mexicanussp. nov., from Mexico (Chiapas). Comments on Lonchodryinus tricolor Kieffer, 1905 are presented and new geographic records are provided for the Brazilian states of Minas Gerais and Paraná. The key to the females of the Neotropical Deinodryinus is updated, and illustrations and distributional maps are provided for the species studied here.(AU)

RESUMO
BACKGROUND: Anteon is a speciose genus widespread in all zoogeographical regions, except Antarctica. NEW INFORMATION: A new species, Anteon hubeni sp. n., is described below from Ecuador, Pichincha Province. The new species is similar to Anteon oliveirai Olmi, known from Brazil, Minas Gerais. The main difference between these two species concerns the sculpture of the frons: in A. oliveirai, the frons shows two lateral keels around the orbits directed towards the antennal toruli, whereas in A. hubeni, these keels are not present. The key to the Neotropical species of Anteon is modified to include the new species.
RESUMO
Metanteon poirieri sp. nov. (Hymenoptera: Dryinidae: Anteoninae) is described from New Caledonia. The genus Metanteon Olmi, 1984, was known only from the southern region of Argentina and Chile. The unique species attributed previously to this genus is M. aerias (Walker, 1839), collected in Chile by Charles Darwin during his famous trip on the HMS Beagle. M. aerias is associated only with leafhoppers feeding on Southern Beeches (Nothofagus spp.), a genus of Nothofagaceae including species of trees and shrubs native to the southern Hemisphere in southern South America (Argentina, Chile) and Australasia (east and southeast Australia, New Zealand, New Guinea and New Caledonia). Like Nothofagus, Metanteon is a transantarctic organism.

A new species of Gonatopus Ljungh, 1810, G.jaliscanus sp. n., from Jalisco, Mexico, is described and illustrated. In the Neotropical region, G.jaliscanus is similar to G.forestalis Olmi, 1998, but it is distinguished by the black mesosoma (except prothorax, mesoscutum, and mesoscutellum that are yellow), and the metapostnotum being granulated and not rugose; in G.forestalis the mesosoma is completely black and the metapostnotum is granulated and strongly rugose. In the Nearctic region, the new species is morphologically similar to G.curriei Krombein, 1962, but it is distinguished by the dull and granulated metapostonotum; in G.curriei the metapostnotum is shiny and unsculptured. The new species belongs to Gonatopus group 7. The keys to the females of the Nearctic and Neotropical species of this group are modified to include the new taxon.
RESUMO
Gonatopus duranprietoae sp. nov. (Hymenoptera: Dryinidae: Gonatopodinae) from Colombia is described and illustrated. This new species belongs to Gonatopus group 7. In this group, G. duranprietoae is similar to G. peruvianus Olmi, from Peru. The main difference between these two species is the shape of the metanotum: in G. duranprietoae lateral regions with two small pointed protrusions, which are absent in G. peruvianus. The key to the Neotropical species of Gonatopus group 7 is modified to include this new species.

Se estudiaron los parasitoides de la chicharrita del maíz, Dalbulus maidis (DeLong & Wolcott) (Hemiptera: Auchenorrhyncha) en la provincia de Tucumán, Argentina. Las chicharritas atacadas por Dryinidae (Hymenoptera: Chrysidoidea) fueron colectadas en campos de maíz entre dic 2003 y abr 2005. Se obtuvieron driínidos de tres especies diferentes: Gonatopus caraibicus (Olmi), Gonatopus contortus Olmi, y G. moyaraygozai Olmi. Se cita por primera vez a G. moyaraygozai en Argentina, y se describe al macho de dicha especie. Se registra por primera vez en campo la asociación parasitoide-hospedador de G. caraibicus y D. maidis; además, se mencionan por primera vez a G. contortus y G. moyaraygozai como parasitoides de la chicharrita del maíz. Se calculó la tasa de parasitoidización de G. moyaraygozai en campo.
