RESUMO

Illustrated keys for the identification of the fourth-instar larvae and adults of species representing six genera of mosquitoes in Thailand are presented, along with information about the geographic distribution of the species and the habitats occupied by their immature stages. Fifty-nine species belonging to genera Orthopodomyia, Kimia, Malaya, Topomyia, Tripteroides, and Toxorhynchites are recognized. Topomyia argyropalpis, To. bifurcata, To. gracilis, To. spathulirostris, To. tenuis, To. tipuliformis, and To. vijayae are included as new country records, and ten undescribed species, four in Topomyia, four in Toxorhynchites, and two in Tripteroides, are recognized.

RESUMO

Illustrated keys for the identification of the larvae and adult female Anopheles mosquitoes of Thailand are presented along with distribution maps, tabulated bionomics information, and a checklist. A total of 73 species are treated, including 71 previously and newly described species (An. cracens = dirus B, An. scanloni = dirus C, An. baimaii = dirus D, An. latens = leucosphyrus A, and An. epiroticus = sundaicus A). Also, two undescribed species are included, i.e., An. minimus C and a new species near An. gigas. Thirty-four chromosomal forms of 14 species are discussed, with suggestions provided for resolving their taxonomic status.

RESUMO

Malaria transmission in the Southern Colombian state of Putumayo continues despite the absence of traditional vector species, except for the presence of Anopheles darlingi near the southeastern border with the state of Amazonas. In order to facilitate malaria vector incrimination in Putumayo, 2445 morphologically identified Anopheles females were tested for natural infection of Plasmodium vivax by ELISA. Specimens tested included An. apicimacula (n = 2), An. benarrochi B (n = 1617), An. darlingi (n = 29), An. mattogrossensis (n = 7), An. neomaculipalpus (n = 7), An. oswaldoi (n = 362), An. peryassui (n = 1), An. punctimacula (n = 1), An. rangeli (n = 413), and An. triannulatus (n = 6). Despite being overwhelmingly the most anthropophilic species in the region and comprising 66.1 percent of the mosquitoes tested, An. benarrochi B was not shown to be a vector. Thirty-five An. rangeli and one An. oswaldoi were naturally infected with P. vivax VK210. Sequence data were generated for the nuclear second internal transcriber space region of 31 of these 36 vivax positive mosquitoes (86.1 percent) to confirm their morphological identification. An. oswaldoi is known to be a species complex in Latin America, but its internal taxonomy remains unresolved. Herein we show that the An. oswaldoi found in the state of Putumayo is genetically similar to specimens from the state of Amapá in Brazil and from the Ocama region in the state of Amazonas in Venezuela, and that this form harbors natural infections of P. vivax. That An. rangeli and this member of the An. oswaldoi complex are incriminated as malaria vectors in Putumayo, is a novel finding of significance for malaria control in Southern Colombia, and possibly in other areas of Latin America.

RESUMO

Illustrated keys for the identification of the fourth-instar larvae and adult females of the mosquito genera Culex and Lutzia is presented, along with information on the geographic distribution of each species, and bionomics. Eighty-two species belonging to subgenera Culex, Culiciomyia, Eumelanomyia, Lophoceraomyia, and Oculeomyia of genus Culex, and three species belonging to subgenus Metalutzia of genus Lutzia are recognized in Thailand. Subgenus Oculeomyia includes a probable new species near Cx. infula and Lt. vorax is recognized as a new country record.

RESUMO

Apresenta-se lista das espécies da tribo Aedini das Américas Central e do Sul, com a combinacão atual de gêneros. Objetiva-se oferecer subsídios aos entomologistas, pessoas dos servicos de saúde e todos os envolvidos com o controle de mosquitos para torna-los familiarizados mais rapidamente com as alteracões taxonômicas atuais propostas para a tribo.

RESUMO

A list of the currently valid generic and species-level taxa of tribe Aedini in Thailand is provided. Its purpose is to enable entomologists, public health personnel and mosquito control workers to more quickly become familiar with recent formal taxonomic changes within the tribe. New country records of four species of Armigeres are reported.

RESUMO

Con el propósito de ampliar el conocimiento sobre las especies de Anopheles presentes en el Putumayo, sur de Colombia, y para esclarecer la identidad de los ejemplares clasificados como Anopheles (Nyssorhynchus) evansae en esta región, se recolectaron mosquitos hembra en cebo humano, se alimentaron en pequeños mamíferos y se mantuvieron vivos para la cría de isofamilias. Se realizaron observaciones de las características morfológicas de los huevos, larvas, pupas y adultos de ambos sexos, incluidas las genitalias masculinas. Se obtuvieron 247 posturas de madres identificadas preliminarmente como A. (N) evansee. A 27 de estas familias se le estudió la morfología de los estadios asociados. Todos los especímenes fueron subsecuentemente identificados como Anopheles (N:) benarrochi por la morfología de los huevos, larvas, pupas y genitalias masculinas, lo cual coincidió con las descripciones publicadas para esta especie. Sin embargo, los adultos hembra de Putumayo presentaron la proporción oscura en el tarsómero posterior 2, entre 0.17 y 0,33 de su longitud, inferior a lo informado para esta especie, lo cual se superpone con los rangos de Anopheles (N.) oswaldoi y A. (N.) evansae. Como resultado de la superposición en este carácter, es probable que hembras adultas de A. (N.) benarrochi hayan sido incorrectamente identificadas como A. (N.) evansae y A. (N.) oswaldoi en el sur de Colombia. La presencia de esta variante morfológica ha dificultado la identificación de A. (N.) benarrochi en Putumayo y, probablemente, en otras regiones de Colombia y países vecinos

RESUMO

Culex (Culex) maxi Dyar is described in the adult, pupal and larval stages, and the male genitalia and parts of the fourth-instar larva are illustrated. The larva is described for the first time. The paper includes a summary of available information on the taxonomy, bionomics and distribution of the species. The taxonomy and identification of the species are reviewed in light of current knowledge of the subgenus Culex in the New World.
