| Members of Buenoa are restricted to the Western Hemisphere, with the greatest diversity of species in South America. There are about 50 described species and approximately 20 of them have been reported from Brazil. Buenoa pseudomutabilis Barbosa, Ribeiro and Nessimian, sp. nov. is described here from Maricá, Rio de Janeiro State. This species resembles B. mutabilis Truxal, 1953 because males have a stridulatory area on inner surface of forefemur, forefemur narrowed at apex, with length more than three times its width at apex, and rostral prong longer than third rostral segment. Males of B. pseudomutabilis sp. nov. can be readily recognized by the presence of 21 to 25 teeth in the stridulatory comb of foretibia, whereas in B. mutabilis the stridulatory comb... |

| A new species of Homalocerus Schoenherr from the Atlantic coast of the State of São Paulo, Brazil (Coleoptera, Belidae, Belinae), with notes on color pattern and on the sclerites of the internal sac. Homalocerus bimaculatus sp. nov. (type locality: Brazil, São Paulo) is described and illustrated, and comments on the sclerites of the internal sac of aedeagus and on color pattern are provided. The new species is compared to other similar species of the genus, being distinguished by having three clusters of carmine pubescence on pronotum and two lateral whitish oval spots located slightly before the middle of each elytron. Six species of Homalocerus, including the new one, are known from the State of São Paulo. The previously published identification key for... |

| ABSTRACT Advances in potter wasp systematics have been achieved recently, with classificatory changes resulting from analyses based upon large scale molecular datasets. For the Neotropics, recent hypotheses point to the occurrence of an exclusive clade recognized within the tribe Eumenini. In this group, several contributions regarding taxonomy and systematics have been proposed in the last five years, including the genus Alphamenes. This taxon contains seven described species whose distribution is exclusively Neotropical. Females are morphologically homogeneous, and characters related to copulatory organs are useful in male diagnosis. This contribution forms the first phylogenetic approach to include all species of Alphamenes, hence the first to strongly... |

| ABSTRACT In several arthropod groups, male genitalia is the most important feature for species identification, especially in cryptic species. Cryptic species are very common in the Drosophila genus, and the Neotropical Drosophila willistoni species group is a good example. This group currently includes 24 species divided into three subgroups: alagitans, bocainensis and willistoni. There are six sibling species in the willistoni subgroup – D. willistoni, D. insularis, D. tropicalis, D. equinoxialis, D. pavlovskiana and D. paulistorum, which is a species complex composed of six semispecies – Amazonian, Andean-Brazilian, Centroamerican, Interior, Orinocan and Transitional. The objective of this study was to characterize male genitalia of the willistoni... |

| Anopheles (Nyssorhynchus) oswaldoi (Peryassú) comprises a species complex in South America. Specimens from two localities in east Mata Atlântica were characterized both at the morphological and molecular level as An. oswaldoi s.s. Intraspecific variation of the shape of the apex of the aedeagus of the male genitalia of specimens of Anopheles (Nyssorhynchus) oswaldoi s.s. from Vale do Ribeira, Mata Atlântica, São Paulo State, Brazil, was observed. Distinctive aedeagus of the specimens from Vale do Ribeira, Mata Atlântica, were evaluated, illustrated and compared to that of An. oswaldoi s.s. |

| This paper deals with two species of Scoposcartula Young, 1977 that are very similar to each other externally (form and color pattern): S. frontaliana (Metcalf, 1955) comb. nov. (from the state of Bahia, NE. Brazil) and S. talitae Leal, Mejdalani & Cavichioli, 2005 (from the state of Espírito Santo, SE. Brazil). The former species, previously positioned in Amblyscarta Stål, 1869, is redescribed and a male specimen is selected as the lectotype. The previously unknown female of the latter species is described for the first time. Scoposcartula frontaliana can be distinguished from S. talitae by features of the male and female genitalia. The most remarkable difference is in the male pygofer, which has a conspicuously concave posterior margin in S.... |

| The species of Rheumatogonus (Gerridae: Ptilomerinae) from Thailand, Borneo, Mindanao and Sri Lanka are revised. Four new species, collected from northern Borneo and Sri Lanka, are described: R. esakii spec. nov. from Brunei, R. vantoli spec. nov. and R. inusitatus spec. nov., both from Sabah, and R. cheliforus spec. nov. from Sri Lanka. Redescriptions of the genus and the four known species assigned to this paper are provided. A key to species with diagnostic illustrations is presented. The male genital structures are illustrated in detail, as they provide the most reliable specific characters. The pilosity on the connexival segment VI is used for identifying the females. |

| The Drosophila peruensis species group was recently proposed and includes four taxa: D. atalaia Vilela & Sene, 1982, D. boraceia Vilela & Val, 2004, D. pauliceia Ratcov & Vilela, 2007, and D. peruensis Wheeler, 1959. All these species have most of setae or setulae of mesonotum arinsing from dark spots, wings with crossveins darker (except in D. atalaia) and hypandrium squared-shaped mostly fused to gonopods. Here, we describe two new species, Drosophila itacorubi sp. nov. and Drosophila paraitacorubi sp. nov., belonging to this species group. The male genitalia of these species are figured. An identification key to the D. peruensis species group is provided. |
