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.

A new species of Leschenaultia Robineau-Desvoidy (Diptera, Tachinidae) from Venezuela and new geographical records

Leschenaultia barbarae sp. nov. is described from Cojedes state, Venezuela. This species is similar to Leschenaultia bicolor (Macquart, 1846) but can be distinguished from this species by the combination of the following characters: anterior tarsal claws longer than second tarsomere of the same leg, and cerci, in lateral view, finer and no so strongly curved back as in L. bicolor (Macquart).

A new genus and species of gall midge (Diptera, Cecidomyiidae) associated with Myrcia retorta (Myrtaceae)

Metapyrophorus pharolim a new genus and species of Pyrophorini (Coleoptera, Elateridae, Agrypninae)

Metapyrophorus, a new monotypic genus, is erected based on M. pharolim, new species from Trinidad and Tobago and Venezuela. The genus is characterized mainly by its pair of convex pronotal bioluminescent organs, equidistant between the median line and the lateral margin.

A new species of Dicrepidius Eschscholtz from Brazil and new records for D. ramicornis (Palisot de Beauvois) (Coleoptera, Elateridae, Elaterinae)

Dicrepidius brasilianus sp. nov., from Pará and Mato Grosso is described and illustrated. This is the second species of this genus recorded from Brazil. D. ramicornis (Palisot de Beauvois, 1805) is widely distributed from south of United States to south of Brazil. From Brazil, it was recorded from Minas Gerais, Rio de Janeiro, São Paulo and Santa Catarina states, but now other records are included. A comparison between the two Brazilian species and a discussion, including intraspecific variations, are presented.

The small species of Belostoma Latreille (Heteroptera, Belostomatidae). III. A revision of oxyurum group, with a new species from Brazil and description of the male of B. noualhieri Montandon

Species of the oxyurum group (sensu Lauck) consist of five extant Neotropical small species, whose lengths range 15.0 to 20.0 mm. The anterior interocular width about 1.5 times the width of an eye and ventral diverticulum of phallus flattened, circular, and large are, in combination, diagnostic. The small species of the oxyurum group were included in the Lauck´s key to the identification of the species groups, without dealing with the species included in it because many of them are very similar in appearance. Therefore here we redescribe and key the Belostoma species of the oxyurum group. Belostoma oxyurum (Dufour) is newly recorded from Brazil (Paraná and Rio Grande do Sul). Holotype and lectotype are designated for B. oxyurum and B. sanctulum Montandon, respectively. The aspect of the prosternal keel, the ratio between the width of the ventral diverticulum of phallus and its length in ventral view, and the aspect of dorsal arms of ventral diverticulum have proven useful for better species delimitation. Based on specimens from Pará State (N. Brazil), Belostoma carajaensis Ribeiro & Estévez, sp. nov. is described and illustrated. This new species differs from B. sanctulum in having anteoculus shorter than interoculus and the dorsal arms of ventral diverticulum divergent and large. A male specimen of B. noualhieri Montandon was collected in São Paulo State and based mainly on features of male genitalia, this species is here also included under oxyurum group.

Copel. are described from Brazil (larva, pupa, male, female, and gall).
