Doryctopambolus Nunes & Zaldívar-Riverón (Braconidae), a new neotropical doryctine wasp genus with propodeal spines.

Abstract The new Neotropical doryctine genus Doryctopambolus gen. n. is erected to contain Doryctopambolus pilcomayensis (van Achterberg & Braet, 2004), comb. n., which was previously placed within Pambolus (Pambolinae), as well as three new species, Doryctopambolus clebschi sp. n., Doryctopambolus dominicanus sp. n. and Doryctopambolus sarochensis sp. n. Members of this new genus are mainly characterised by the presence of at least one pair of conspicuous propodeal apico-lateral projections, which are similar to those present in all members of Pambolinae and in species of three Australasian doryctine genera. We generated DNA barcoding sequences for the three newly described species. We discuss the morphological similarity between species of the Australasian Echinodoryctes Belokobylskij, Iqbal & Austin and Doryctopambolus. A key for the described species of Doryctopambolus is provided.

A new species of Heredius Marsh 2002 (Hymenoptera: Braconidae: Doryctinae) from Brazil

A new species of Heredius Marsh, 2002 is described from Brazil. H. flavus n. sp. differs from the other known Heredius species by its yellow mesosoma and metasoma, acinose-carinate face, acinose temple, malar space length about 0.56 times eye height, ocello-ocular distance about 4.0 times diameter of the lateral ocellus; acinose-rugose mesoscutal lobes, sternaulus finely scrobiculate and almost complete, and first metasomal tergum with apical width almost equal its length.

Two new species of Pedinotus Szépligeti 1902 (Hymenoptera: Braconidae: Doryctinae) from the Savannah in São Paulo state, Brazil

Two new species of Pedinotus genus are described from the Brazilian savannah area, providing a new key to identify the species.

Systematics and distribution of the genus Johnsonius Marsh (Hymenoptera, Braconidae, Doryctinae) with description of two new species from Brazil

The genus Johnsonius Marsh includes five species, most of them known from Costa Rica and one known from Venezuela, Peru and Costa Rica. Two of these species and two new species were recently collected in Atlantic rain forest. Description of the new species, illustrations of some morphological characters, a key for identification of all known species and the new geographic records are presented.
