Anopheles (Nyssorhynchus) striatus, a new species of the Strodei Subgroup (Diptera, Culicidae)

ABSTRACT A new species of the genus Anopheles Meigen (Diptera: Culicidae), Anopheles (Nyssorhynchus) striatus n. sp., preliminary designated as Anopheles CP Form, from Brazil, is here validated and described using morphological characteristics of the egg, fourth-instar larva, pupa, female and male genitalia. The species is morphologically more similar to species of the Strodei Subgroup of Anopheles (Nyssorhynchus) than to any other species of the subgenus Nyssorhynchus Blanchard. However, adult female that can be misidentified with Anopheles (Nyssorhynchus) galvaoi Causey, Deane & Deane if the identification is mainly based on the ratio of dark and white scales of the hindtarsomere 2. In addition, the characterization of the new species includes aspects of its bionomics, and geographical distribution. The new species is known from Espírito Santo, Minas Gerais and Paraná states, in Brazil. Diagnostic characters for the identification of the species are provided.

Nuevos registros de mosquitos (Diptera Culicidae) para el estado Bolívar, Venezuela: Dos de ellos nuevos para el país / New records of mosquitoes (Diptera Culicidae) for the state of Bolivar, Venezuela: Two of them new to the country

En el presente trabajo se hace referencia por primera vez para el estado Bolívar de diez y nueve especies de mosquitos (Diptera Culicidae), pertenecientes a diez (10) géneros: Anopheles, Chagasia, Culex, Aedes, Mansonia, Coquilletidia, Uranotaenia, Psorophora, Limatus y Wyeomyia, de las subfamilias Anophelinae y Culicinae. Dos de estas especies, son citadas por primera vez para Venezuela: Chagasia bonneae Root, 1927 y Chagasia ablusa Harbach, 2009.

First report of 19 Culicidae species (Diptera: Culicidae) from Bolivar State is made, belonging to 10 genera of Anophelinae and Culicinae: Anopheles, Chagasia, Culex, Aedes, Mansonia, Coquilletidia, Uranotaenia, Psorophora, Limatus and Wyeomyia. Chagasia bonneae Root, 1927 and Chagasia ablusa Harbach, 2009 are reported for the first time in Venezuela.

Efeitos da implantação da Usina Hidrelétrica de Rosal, Rio Itabapoana, Estados do Espírito Santo e Rio de Janeiro, sobre anofelinos, planorbídeos e flebotomíneos / Effects of the installation of the Rosal hydroelectric power station, Itabapoana River, States of Espírito Santo and Rio de Janeiro, on anophelinae, planorbidae and phlebotominae

A construção de represas geralmente causa modificações na composição da fauna em sua área de influência. Na área de implantação da Usina Hidrelétrica de Rosal, Estados do Espírito Santo e Rio de Janeiro, foram avaliadas modificações na abundância de anofelinos, planorbídeos e flebotomíneos antes (1998-2000) e após (2000-2005) o represamento. Foram definidos nove pontos de coleta, cada qual representado por uma moradia e seus anexos, abrigos de animais domésticos e coleções hídricas num raio de 150m. Coletaram-se 103 anofelinos adultos antes do represamento e 313 depois, 200 imaturos antes e 708 depois, 868 planorbídeos antes e 486 depois, e 2.979 flebotomíneos antes e 912 depois. O registro de vetores dentre anofelinos, planorbídeos e flebotomíneos revela o potencial da área para transmissão de malária, esquistossomose e leishmaniose tegumentar. As transformações ambientais ocorridas, no entanto, não aumentaram o risco para ocorrência dessas doenças.

The construction of dams usually changes the composition of the fauna within their areas of influence. In the area where the Rosal hydroelectric power station has been installed, in the States of Espírito Santo and Rio de Janeiro, changes to the abundance of anophelinae, planorbidae and phlebotominae were evaluated before (1998-2000) and after (2000-2005) the damming. Nine sample collection points were defined, each represented by a home and its outbuildings, shelters for domestic animals and water collection points within a radius of 150m. One hundred and three adult anophelinae were collected before the damming and 313 afterwards; 200 immature anophelinae before and 708 afterwards; 868 planorbidae before and 486 afterwards; and 2,979 phlebotominae before and 912 afterwards. The vector record, consisting of anophelinae, planorbidae and phlebotominae, shows the potential of this area for transmission of malaria, schistosomiasis and American cutaneous leishmaniasis. However, the environmental changes did not increase the risk of the occurrence of these diseases.

Cladistic analysis of the subgenus Anopheles (Anopheles) Meigen (Diptera: Culicidae) based on morphological characters

In the present study, we used morphological characters to estimate phylogenetic relationships among members of the subgenus Anopheles Meigen. Phylogenetic analyses were carried out for 36 species of Anopheles (Anopheles). An. (Stethomyia) kompi Edwards, An. (Lophopodomyia) gilesi (Peryassú), Bironella hollandi Taylor, An. (Nyssorhynchus) oswaldoi (Peryassú) and An. (Cellia) maculatus Theobald were employed as outgroups. One hundred one characters of the external morphology of the adult male, adult female, fourth-instar larva, and pupa were scored and analyzed under the parsimony criterion in PAUP. Phylogenetic relationships among the series and several species informal groups of Anopheles (Anopheles) were hypothesized. The results suggest that Anopheles (Anopheles) is monophyletic. Additionally, most species groups included in the analysis were demonstrated to be monophyletic.

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.

Occurrence of the malaria Vector Anopheles albimanus Wiedemman (Diptera: Culicidae) in Isla Fuerte, Colombia / Ocorrência do vetor da malária Anopheles albimanus wiedemann (Diptera: Psychodidae) em Isla Fuerte, Colômbia

Pela primeira vez, é registrada a ocorrência do Anopheles albimanus Wiedemann em Isla Fuerte, Colômbia. Um total de doze mosquitos fêmeas foi capturado com armadilha Shannon em um ambiente peridomiciliar da ilha. Discute-se a relevância epidemiológica desta descoberta.

This is the first report of the occurrence of Anopheles albimanus Wiedemann in Isla Fuerte, Colombia. Twelve female mosquitoes were collected using an illuminated Shannon trap in a peridomestic environment of the island. The epidemiological relevance of this finding is discussed.
