RESUMO
A new species of caddisfly, Itauara marcellina sp. nov., is described and illustrated from Roraima state in northern Brazil. This new species is characterized by features of the male genitalia. The dorsolateral processes of tergum X, in dorsal view, are horn-like and the phallicata has a medial pair of membranous, rounded, lateral flanges projecting posteroventrad. Protoptila ctenacantha Flint 1974 is recorded for the first time from Brazil. Protoptila condylifera Flint 1971, Protoptila flexispina Flint 1971, Protoptila simplex Flint 1971, and Protoptila trispicata Flint 1971 are recorded for the first time from Roraima state, Brazil.

Two new species of Flintiella Angrisano 1995 are described and illustrated from specimens collected with light traps in the states of Pará and Roraima, northern Brazil. Flintiella serrana sp. nov. can be distinguished from all other species in the genus by the subgenital plate with incised apex, and two pairs of ventral processes. Flintiella triaena sp. nov. is distinctive with no clearly similar congeners and can be distinguished from all known species in the genus by the trident-like subgenital plate in ventral view. Additionally, we record the genus Flintiella for the first time in Roraima State.

Two new species of Helicopsychidae from Pará State, Brazil, are described and illustrated: male of Helicopsyche (Feropsyche) carajas n. sp. is characterized by segment X having 8 pairs of subequal megasetae distributed in a pair of longitudinal rows; the primary branch of each gonocoxite, in lateral view, with its basal half nearly as broad as its median part and parallel-sided, its posterior apex directed slightly ventrad and slender and strongly pointed; the dorsal lobes of the endotheca posteriorly protruding, and the lateral lobes of the endotheca well developed. Helicopsyche (Feropsyche) inflata n. sp. is characterized by the hind wings each having very long fringes along the anal border; the primary branch of each gonocoxite having a pointed apex in lateral view and its basimesal lobe being triangular in lateral and ventral views and bearing eight megasetae; and the dorsal lobe of the endotheca being very well developed in lateral view.

A new species of Campylocia is described from Northern Brazil based on male and female imagoes. The main characteristics that distinguish the male imago of the new species from its congeners are: forewings with fork of Rs basal to fork of MA and one or two intercalary veins attached to CuA; general color of abdomen whitish; terga I-VIII with purplish brown dorsolateral area and light colored medial line; terga II-VII with two pairs of light colored drop-shaped spots (one medioapical and one medial); tergum VIII with a medioapical pair of light colored drop-shaped spots; terga IX-X orange; base of penis rectangular; penis lobes adjacent to medial line, laterally directed, without median lobes, fused on basal 1/2 and slender on distal 2/3; subgenital plate rectangular with medial emargination and dark brown margins.

Registra-se pela primeira vez o encontro de Lutzomyia (Nyssomyia) yuilli yuilli Young e Porter, 1972 (Diptera: Psychodidae) no Estado de Roraima, Brasil. Os espécimes foram capturados na área indígena de Auaris, na fronteira com a Venezuela, usando-se armadilhas luminosas tipo CDC instaladas em galinheiros, entre 18 h e 6 h. L. yuilli yuilli é a única espécie vetora de Leishmania sp conhecida até o momento em Auaris e pode estar envolvida na transmissão de Leishmania sp a humanos naquela região.
The first report of Lutzomyia (Nyssomyia) yuilli yuilli Young & Porter, 1972 (Diptera: Psychodidae) in Roraima State, Brazil is presented. The specimens were captured in the Auaris indigenous community, on the border with Venezuela, with CDC light traps set up in henhouses between 18:00 h and 06:00 h. L. yuilli yuilli is the only vector of Leishmania spp. currently known in Auaris and may be involved in the transmission of Leishmania spp. to humans in the area.

Com o objetivo de investigar a presença de vetores de Leishmania e inferir sobre o risco de transmissão de leishmanioses a humanos, foi feito um levantamento de flebotomíneos em área endêmica para leishmaniose tegumentar americana na Serra do Tepequém, localizada no Município de Amajari, Estado de Roraima, Brasil. Os flebotomíneos foram capturados no período de agosto de 2008 a maio de 2009, utilizando-se quatro armadilhas luminosas tipo CDC instaladas a um metro de altura do solo, no interior de floresta primária. Foram capturados 2.230 espécimes distribuídos em 11 subgêneros, quatro grupos de espécies e 38 espécies. Lutzomyia eurypyga foi a espécie mais abundante, representando 72 por cento dos flebotomíneos capturados. O encontro de L. anduzei, L. ayrozai, L. antunesi, L. davisi, L. fíaviscutellata, L. hirsuta, L. paraensis, L. squamiventris squamiventris, L. ubiquitalis e L. umbratilis, vetores comprovados ou suspeitos de leishmânias na Região Amazônica, indica risco de transmissão da doença a humanos na área de estudo. Registram-se pela primeira vez no Estado de Roraima as espécies L. georgii e L. longipennis...
Our study aimed to investigate the presence of vectors of Leishmania and to study the transmission risks of leishmaniasis to humans. Thus, a survey forthe occurrence of sand flies in an endemic area for American cutaneous leishmaniasis was conducted in Serra do Tepequém, City of Amajari, Roraima State, Brazil. The sand flies were captured from August 2008 to May 2009 using four CDC light traps installed 1 m above the ground levei and inside the primary forest. A total of 2,230 specimens were captured. They were distributed into 11 subgenera, four groups of species and 38 species. Lutzomyia eurypyga was the most numerous species, accounting for 72 per cent of ali captured sand flies. The occurrence of L. anduzei, L. ayrozai, L. antunesi, L. davis, L. flaviscutellata, L. hirsuta, L. paraensis, L. squamiventris squamiventris, L. ubiquitalis and L. umbratilis, either proven orsuspected vectors of leishmania in the Amazon Region, indicates risk of transmission of the disease to humans in the study area. For the first time, the species L. georgii and L. longipennis were found in Roraima State...

São apresentados os dados anatômicos da epiderme dos segmentos foliares de Mauritia flexuosa L. f. (Arecaceae) em três fases do desenvolvimento. Os segmentos foliares foram analisados em toda a extensão do limbo. As células intercostais da epiderme das faces adaxial e abaxial evidenciam-se com paredes sinuosas, retangulares e orientadas longitudinalmente em relação ao eixo do segmento foliar com acentuada presença de corpos de sílica esférico-espinulosos. As células epidérmicas da região costal de ambas as faces apresentam paredes retas e variam entre curtas, longas e arredondadas. Os tricomas são simples, unicelulares, longos, com base mais alargada. Os segmentos foliares de M. flexuosa são anfiestomáticos com estômatos tetracíticos. Em secção transversal a epiderme foliar é uniestratificada com câmara subestomática ampla. Os resultados obtidos não demonstraram variações expressivas entre as três fases de desenvolvimento e os caracteres encontrados parecem ser comuns a outras palmeiras.
Anatomic data on the epidermis leaf segments from Mauritia flexuosa L. f. (Arecaceae) are presented on three phases of development. Leaf segments were analyzed on the all extension of leaf. Both adaxial and abaxial epidermal cells stand out with sinuous walls, rectangular and longitudinally oriented to the foliar axis with the marked presence of spherical- spiny silica bodies. The back epidermal cells of both surfaces present straight walls and vary among short, long and round. Trichomes are unicellular, simple, long, with a wider base. Leaf segments from M. flexuosa are anphistomatic with tetracitic type stomats. In a cross-section the leaf skin is unistratified with a broad substimatic chamber. The findings obtained showed no significant variations among the three phases of development and the characters that were found appear to be common on other palm trees.
