v.1(1950)

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.

Resurrection of Anopheles goeldii from synonymy with Anopheles nuneztovari (Diptera, Culicidae) and a new record for Anopheles dunhami in the Brazilian Amazon

Nucleotide sequences of the internal transcribed spacer 2 (ITS2) rDNA and partial sequences of the cytochrome coxidase subunit I (COI) mtDNA and white gene nDNA were obtained from specimens of Anopheles nuneztovari A collected in Macapá (state of Amapá), Óbidos, Prainha and Almeirim (state of Pará), Itacoatiara and Parintins (state of Amazonas), Brazil, and compared with previously published sequences of A. nuneztovari s.l. Results of the Bayesian phylogenetic analyses performed using either COI or combined ITS2, COI and white gene sequences suggest that An. nuneztovari B/C is distinct from specimens obtained in the Amazonas/Solimões River basin. Anopheles goeldii, currently in synonymy with An. nuneztovari, was described from individuals collected in Belterra (= Fordlândia) in the Tapajós River, state of Pará, Southern Amazonas River. Morphological comparisons of the characteristics of the male genitalia indicated that An. nuneztovari A and An. goeldii are similar but distinct from An. nuneztovariB/C by the apex of the aedeagus. In considering the results of the phylogenetic analyses and morphological comparisons, An. goeldii is resurrected from synonymy with An. nuneztovari. Additionally, Anopheles dunhamiis reported for the first time in Parintins. This species can be distinguished from An. goeldiiby characters of the male genitalia and molecular data

Description of a new Tetranychus (Acarina, Prostigmata : Tetranychidae) pest of Musa from French Guiana

A new species of tetranychid mite, genus Tetranychus Dufour, 1832, is described and illustrated herein from neotropical area. Tetranychus musae sp. nov. (Acari, Prostigmata: Tetranychidae) differs from other species in the genus by the combination between the arrangement of leg setae on females tarsus I and the shape of the aedeagus. Tarsus I bears one tactile setae proximal to proximal duplex setae and three tactiles in line or almost in line with proximal duplex setae. The aedeagus knob consists of an acute posterior projection bent ventrally and a larger anterior rounded projection directed anterodorsally. T. musae specimens were collected in French Guiana where they appeared to be a pest of Musa sp. A key to adults of neotropical species of the genus Tetranychus feeding on banana is provided.

Allozymatic divergence between border populations of two cryptic species of the Drosophila buzzatii cluster species (Diptera: Drosophilidae)

Drosophila antonietae and Drosophila gouveai are allopatric, cactophilic, cryptic and endemic of South America species, which aedeagus morphology is considered the main diagnostic character. In this work, single close populations from the edge distributions of each species, located in an ""introgressive corridor"", were analyzed regarding temporal isozenzymatic genetic variability. Isocitrate dehydrogenase (Idh) appeared as a diagnostic locus between D. antonieate and D. gouveai because each population was fixed for different alleles. Moreover, several polymorphic loci showed accentuated divergence in the allele frequency, as evidenced by Nei`s l(0.3188) and D (1.1432), and also by Reynolds` genetic distance and identity (1.3207 and 0.7331, respectively). Our results showed that, in spite of the very similar external morphology, related evolutionary histories, close distributions, and events of introgression in the studied area, these cryptic species have high allozymatic differentiation, and this is discussed here.

A new species of Portanus (Hemiptera, Cicadellidae, Xestocephalinae) from Brazil

Portanus Ball, 1932 comprises 45 species that occur in Brazil, including Portanus felixi sp. nov. described and illustrated herein. The genus is close to Paraportanus Carvalho & Cavichioli, 2009 and can be distinguished from it by having a transversal groove on the basal third of the subgenital plates. The new species can be distinguished from the other species of the genus by the characters of male genitalia, especially by the pygofer with the apical process pointed, sclerotized and dorso-ventrally directed; and by the aedeagus with apodeme on the basal third.

Taxonomy of the Brazilian firefly Cladodes illigeri (Coleoptera, Lampyridae): morphology and new records

ABSTRACT Cladodes illigeri (Kirby, 1818) is redescribed, and can be distinguished by the following features: color pattern overall black, paired spots and elytral margins pale yellow; pygidium bisinuate, posterior angles rounded, as long as median margin; and aedeagus with phallus 1/3 shorter than the parameres, which are sinuated apically. Cladodes lamellicornis (Motschulsky, 1854) is proposed as a junior synomym of C. illigeri. New records from the Atlantic Rainforest and illustrations for structural features are provided.

Hermanlentia n. gen. da tribo Triatomini, com um rol de espécies de Triatominae (Hemiptera, Reduviidae)

Hermanlentia n. gen. of Tribe Triatomini, with a List of Species of Triatominae (Hemiptera, Reduviidae) - Hermanlentia n. gen. was established in the tribe Triatomini, based on differences of external morphology, phallic structures and chromatic characters of Triatoma matsunoi Fernandez-Loayza 1989, in relation to other species of Triatoma. The head is long with disproportionally small eyes 1:0,16; the relation of the head and the pronotum is 1: 0,4; and the coloration of the hemelytron is whitish. Characters of the male genitalia that distinguish the new genus are the articulatory apparatus with twice the size of the aedeagus, phallosoma with fingerlike apex, 1 + 1 dorsal conjuntive processes with the inner edge toothed, and absence of endosoma process and vesica

Systematic notes on Anopheles Meigen (Diptera: Culicidae) species in the state of Amapá, Brazil

Identification of Anopheles nuneztovari Gabaldón and An. goeldii Rozeboom and Gabaldón based on the male genitalia traits is discussed. An. goeldii is in the synonymy of An. nuneztovari, however, characters of the aedeagus of male genitalia distinguish both species. We hypothesize that An. goeldii may be a valid species, however, further studies using molecular characters, especially ITS2 rDNA sequences will be necessary to elucidate the taxonomic status of the species. An. konderi Galvão and Damasceno and An. forattinii Wilkerson and Sallum are registered for the first time in the state of Amapá.

Resurrection of Anopheles goeldii from synonymy with Anopheles nuneztovari (Diptera, Culicidae) and a new record for Anopheles dunhami in the Brazilian Amazon

Nucleotide sequences of the internal transcribed spacer 2 (ITS2) rDNA and partial sequences of the cytochrome coxidase subunit I (COI) mtDNA and white gene nDNA were obtained from specimens of Anopheles nuneztovari A collected in Macapá (state of Amapá), Óbidos, Prainha and Almeirim (state of Pará), Itacoatiara and Parintins (state of Amazonas), Brazil, and compared with previously published sequences of A. nuneztovari s.l. Results of the Bayesian phylogenetic analyses performed using either COI or combined ITS2, COI and white gene sequences suggest that An. nuneztovari B/C is distinct from specimens obtained in the Amazonas/Solimões River basin. Anopheles goeldii, currently in synonymy with An. nuneztovari, was described from individuals collected in Belterra (= Fordlândia) in the Tapajós River, state of Pará, Southern Amazonas River. Morphological comparisons of the characteristics of the male genitalia indicated that An. nuneztovari A and An. goeldii are similar but distinct from An. nuneztovariB/C by the apex of the aedeagus. In considering the results of the phylogenetic analyses and morphological comparisons, An. goeldii is resurrected from synonymy with An. nuneztovari. Additionally, Anopheles dunhamiis reported for the first time in Parintins. This species can be distinguished from An. goeldiiby characters of the male genitalia and molecular data.

A new species of Aurigoniella Takiya, Mejdalani & Felix (Hemiptera, Cicadellidae, Cicadellini) from southern Brazil

Aurigoniella meridionalis, sp. nov. is described and illustrated from Morretes and São José dos Pinhais, Paraná State, southern Brazil. It can be easily distinguished from the Aurigoniella type-species, A. dutrai, by its distinct color pattern, smaller size, shorter crown, hindleg knees attaining lateral lobe of pronotum, aedeagus broadest height around mid-length, and paraphyses ramus biramous.

A new species of Sycorax Curtis, 1839 from Atlantic Forest in southeastern Brazil

A new species of Sycorax Curtis, 1839 (Diptera, Psychodidae) from the Atlantic Forest in southeastern Brazil. Sycorax bravoi Santos, Ferreira & Falqueto sp. nov. is described and illustrated based on samples collected with a Möricke trap installed on the ground at the Biological Station of Santa Lúcia, municipality of Santa Teresa, in the Brazilian state of Espírito Santo. Males have a paramere with a spiniform prolongation on the distal surface and an aedeagus with a long posterior membranous dorsal prolongation. Females have a racket-shaped genital furca and tubular spermatheca, tapered on the apical third. This finding raises the number of Sycorax species known from Brazil to seven.
