Lopesia davillae (Diptera, Cecidomyiidae), a new species of gall midge from Brazil associated with Davilla rugosa (Dilleniaceae) / Lopesia davillae (Diptera, Cecidomyiidae), uma nova espécie de cecidomiídeo do Brazil associada à Davilla rugosa (Dilleniaceae)

Abstract Lopesia davillae, a new species of gall midge associated with the reproductive structures of Davilla rugosa (Dilleniaceae), is described and illustrated (larva, pupa, male, female, and damage) based on material collected in Rio de Janeiro, Brazil. This new species is compared with its congeneric species. This is the first record of Lopesia on Dilleniaceae.

Resumo Lopesia davillae, uma nova espécie de Cecidomyiidae associada a estruturas reprodutivas de Davilla rugosa (Dilleniaceae), é descrita e ilustrada (larva, pupa, macho, fêmea e dano) com base em material coletado no estado do Rio de Janeiro, Brasil. A nova espécie é comparada com as outras espécies conhecidas do mesmo gênero. Este é o primeiro registro de Lopesia em Dilleniaceae.

A study to identify the presence of Aedes Spp. using BG-Sentinel® Traps and larval/pupal surveys in communities around Belmopan, Cayo District.

The knowledge of the presence of Aedes Spp. mosquitoes is very important for the prevention and control of emerging and remerging diseases caused by Arboviruses such as: Yellow fever, Dengue, Chikungunya and Zika. While Chikungunya and Dengue are endemic to Belize, Zika is currently a threat with local transmission having been established in several Caribbean and Central American Countries. The objective of the study is to survey the presence of Ae. aegypti and Ae. albopictus in the communities of San Martin, Salvapan and Las Flores, Belmopan City. The study was conducted from March 14 to April 2, 2016 whereby adult mosquitoes were captured using BG-Sentinel® Traps and larvae/pupae collection surveys were also done. Three hundred meter zone(s) were determined within localities and 1 BG-Sentinel® trap was deployed for 3 days at 24-hour intervals both indoors and outdoors at 2 residences randomly selected in each community. Larvae/Pupae collection surveys were done at 5 private premises within the predetermined zones in each of the three communities. Captured larvae and Pupae were reared for 6 days and adults obtained were used for identification. The identification of adult Ae. aegypti and Ae. albopictus was done using a stereoscopic microscope and pictorial keys that are used for the identification of mosquitoes. The presence of Ae. aegypti was identified in all 3 communities through both adult mosquito and larvae/pupae collections. However, Ae. albopictus was present only in San Martin and Salvapan communities. The presence of Ae. aegypti and/or Ae. albopictus will determine which appropriate vector control interventions are needed considering the different characteristic breeding habitats of these mosquitoes.(AU)

Simulium (Inaequalium) marins, a new species of black fly (Diptera: Simuliidae) from inselbergs in Brazil

A new species of black fly, Simulium (Inaequalium) marins (Diptera: Simuliidae), is described based on the male, female, pupa and larva. This new species was collected from two localities: a small stream on the Pico dos Marins, a high mountain with granite outcrops in Piquete County, state of São Paulo, and in a small stream in the Serra dos Órgãos National Park, state of Rio de Janeiro, Brazil.

Local distribution of blackfly (Diptera, Simuliidae) larvae in two adjacent streams: the role of water current velocity in the diversity of blackfly larvae / Distribuição local de larvas de simulídeos (Diptera, Simuliidae) em dois rios adjacentes: O papel da velocidade da correnteza na diversidade de larvas de simulídeos

This study aimed to evaluate the influence of water velocity speed on the local distribution and taxocenosis structure of blackfly larvae. The larvae were collected from two adjacent streams located in the municipality of Angra dos Reis (RJ): Caputera River and one of its tributaries. Riffle litter patches were sampled randomly using a 30 x 30 cm quadrat. Four blackfly species were found: Simulium incrustatum s. l. Lutz, 1910; Simulium (Inaequalium) sp. ; Simulium pertinax s. l. Kollar, 1832 and Simulium subpallidum s. l. Lutz, 1909. Among these species, Simulium pertinax s. l. was clearly associated with higher water current speeds, while Simulium subpallidum s. l. showed association with lower water velocities, and Simulium (Inaequalium) sp. had a relatively constant distribution along the water current gradient.

Este estudo teve como objetivo avaliar, nos criadouros de simulídeos, a influência da velocidade da água sobre a ocorrência de suas larvas e estrutura de suas taxocenoses. Para obtenção da amostragem foram utilizados "quadrats" de madeira distribuídos aleatoriamente no rio Caputera e um de seus tributários. Foram encontradas quatro espécies: Simulium incrustatum sl. Lutz, 1910; Simulium (Inaequalium) sp. ; Simulium pertinax sl. Kollar, 1832 e Simulium subpallidum sl. Lutz 1909. S. (Inaequalium) sp. teve uma distribuição quase constante ao longo do gradiente de correnteza. S. pertinax se mostrou fortemente associada às velocidades mais altas de correnteza, enquanto que S. subpallidum se mostrou associado às velocidades mais baixas.

Systematics of Anopheles lanei Galvão and Amaral, a species of the subgenus Nyssorhynchus Blanchard (Diptera: Culicidae)

Anopheles (Nyssorhynchus) lanei Galvão and Amaral is here redescribed using morphological characteristics of adult, male and female, fourth instar larva and pupa. The larva, pupa, and male genitalia are illustrated. Diagnostic morphological characters of adults, male genitalia, fourth instar larva and pupa are provided to distinguish An. lanei from other species of the Argyritarsis section. Species distribution data are based on the published literature records and bionomics data are based on both literature records and field data.

Descrição da larva, exúvia pupal e macho de Leucotabanus albovarius (Walker) (Diptera, Tabanidae) da Amazônia Central / Description of larva, pupal exuvia and male of Leucotabanus albovarius (Walker) (Diptera, Tabanidae) from Central Amazonia

Immature stages and male adult of Leucotabanus albovarius (Walker, 1854) are described and figured for the first time. The larva was found in rotten wood of the palm Bactris gasipaes Kunth (Arecaceae) near Manaus. Differential diagnoses of the known immatures of Leucotabanus Lutz are presented.

Estágios imaturos e macho adulto de Leucotabanus albovarius (Walker, 1854) são descritos e ilustrados pela primeira vez. A larva foi encontrada em tronco de pupunheira em decomposição, Bactris gasipaes Kunth (Arecaceae), nas proximidades de Manaus. Diagnoses diferenciais dos imaturos de Leucotabanus Lutz são apresentadas.
