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 Sycorax (Diptera, Psychodidae, Sycoracinae) from the Pacific coast of Colombia

Sycorax utriensis n. sp. is described and illustrated from a male specimen collected with a CDC light trap in the Parque Nacional Natural Ensenada de Utría, on the Pacific Coast of Colombia. Five species of Sycorax are now known from Colombia, S. andicola Young, 1979, S. colombiensis Young, 1979, S. fairchildi Young, 1979, S. trispinosa Young, 1979 and S. utriensis n. sp.

New species of Hymenoptera associated with galls on Calliandra brevipes Benth. (Fabaceae, Mimosoidea) in Brazil

Four species of Hymenoptera: Tanaostigmodes ringueleti (Brèthes, 1924), T. mecanga sp.nov. (Chalcidoidea, Tanaostigmatidae), Allorhogas taua sp. nov. (Braconidae, Doryctinae) and Eurytoma sp. (Chalcidoidea, Eurytomidae) were reared from two different types of galls of Calliandra brevipes Benth. (Fabaceae, Mimosoidea) in Juiz-de-Fora, Minas Gerais State, Brazil. The two Tanaostigmatidae species are probably the gall inducers; the Braconidae species probably is phytophagous inquiline in round gall type. The two new species are described and illustrated, including their immature stages.

A new species of the fungus-farming ant genus Mycetagroicus Brandão & Mayhé-Nunes (Hymenoptera, Formicidae, Attini)

The fungus-farming ant genus Mycetagroicus Brandão & Mayhé-Nunes was proposed based on three species from the Brazilian "Cerrado": M. cerradensis, M. triangularis and M. urbanus. Here we describe a new species of Attini ant of the genus Mycetagroicus, M. inflatus n. sp., based on two workers collected in eastern Pará State, Brazil. A new key for species identification, comments on differences among species and new geographical distribution data are furnished.

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).

First record of the genus Myllaena Erichson from Brazil, description of a new species and annotated catalog of Myllaena species from the Neotropical region (Coleoptera, Staphylinidae, Aleocharinae)

The genus Myllaena Erichson, 1837, of the tribe Myllaenini Ganglbauer, 1895, is recorded from Brazil for the first time. A new species, Myllaena brasiliensis sp. nov., is described and illustrated; it is closely related to the insomnis species group, described from the Nearctic region. A short diagnosis of the genus and an annotated catalog of Myllaena species from the Neotropical region are also provided.

A new species of the genus Pimelerodius Vanin from the Amazon Region, with notes on the geografic distribution of Pimelerodius motacilla (Boheman) (Coleoptera, Curculionidae, Otidocephalini)

Pimelerodius punctiventris sp. nov. (type locality Brazil, Amazonas, Itacoatiara) is described and illustrated. The new taxon is compared with similar species, being distinguished from the other 12 known species of the genus by the presence of punctures in ventrite I. The available published key for identification of species of Pimelerodius is adapted to include the new species. A modification of the generic description of the aedeagus of Pimelerodius is provided, a necessity due to the differences observed in the aedeagus of the new species. The occurrence of P. motacilla (Boheman, 1843) in the Amazon Region, recorded in sympatry with P. punctiventris in Itacoatiara, AM, is discussed and confirmed, based on the study of 41 available specimens.

New species of Hymenoepimecis Viereck (Hymenoptera, Ichneumonidae, Pimplinae) from Brazilian Atlantic forest

In this study three new Brazilian species of Hymenoepimecis are described and illustrated. The specimens were collected using sweeping the vegetation and Malaise traps in areas of Atlantic forest in southeastern Brazil. The material described is figured with digital images.

New species and records of Chimarra Stephens (Trichoptera, Philopotamidae) from Central Amazonia, Brazil

Chimarra (Curgia) paucispina sp. nov., of the aurivittata group Flint, 1998 is described and illustrated from specimens collected in Amazonas State. The key to species of Chimarra (Curgia) Walker, 1860 presented by Flint was modified to include the new species. Chimarra (Chimarrita) chela Blahnik, 1997 and Chimarra (Curgia) jugescens Flint, 1998 are for first time reported for the Amazonas State. This is the first record of C. chela in Brazil.

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.

Neolasioptera ramicola, a new species of Cecidomyiidae (Diptera) associated with Physalis angulata (Solanaceae)

Neolasioptera ramicola Maia, a new species of Cecidomyiidae (Diptera) that induces stem galls on Physalis angulata (Solanaceae) is described and illustrated (larva, pupa, male, female and gall) based on material from Bento Gonçalves, Rio Grande do Sul, Brazil.

Asphondylia fructicola, a new species of Cecidomyiidae (Diptera) associated with Solanum sp. (Solanaceae) from Brazil

Asphondylia fructicola sp. nov. is described and illustrated on the basis of the larva, pupa, male, female, and gall. This species induces galls on fruits of Solanum sp. (Solanaceae) in Amazonia, Brazil.

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.

A new species of Seira Lubbock (Collembola, Entomobryidae), with a key to the species of Paraíba, Brazil

A new species of Entomobryidae of the genus Seira Lubbock, S. paraibensis sp. nov. is described and illustrated. The type locality of the species is the municipality of Areia, state of Paraíba, Brazil. The species was found inhabiting the Atlantic forest litter and top soil environment. S. paraibensis sp. nov. resembles S. pseudoannulata in many morphological features. This is the sixth species of the genus found and described in Paraiba so far. A key with the 11 species of Seira registered so far in Paraíba is provided. Also a list with all species of the genus from Brazil is presented.

A new species of Solepyris Azevedo (Hymenoptera, Bethylidae) from Brazil, with amended diagnosis of the genus

Solepyris Azevedo is a rarely collected Neotropical genus. It is differentiated from other Sclerodermini genera by having the fore wing venation with a single large closed cell and currently is monotypic containing S. unicus Azevedo. A second species, Solepyris montuosus, sp. nov., from Brazil is described and illustrated. This new species is diagnosed by having radial vein of the fore wing long. An amended diagnosis of Solepyris unicus Azevedo is included. A key for the two species of Solepyris is provided.
