“…braziliensis were sometimes of secondary importance as malaria vectors (Deane et al 1946(Deane et al , 1948. In our study we determined species carrying human malaria sporozoites detectable by ELISA, were the same as those reported in past studies in Brazil (Arruda et al 1986, Tadei et al 1988, Lourenço-de-Oliveira et al 1989, Branquinho et al 1996, plus An. braziliensis and An.…”

“…Theobald, 1903 (now a complex of three species - Sallum et al 1999) and An. triannulatus (Neiva and Pinto, 1922) are considered to be potentially regional vectors (Arruda et al 1986, Tadei et al 1988, Deane 1988, Lourenço-de-Oliveira et al 1989, Klein et al 1991, Branquinho et al 1996 and, more recently, An. marajoara Galvão and Damasceno, 1942 has been determined to be a new emerging malaria vector near Macapá, State of Amapá (Segura 1998).…”

“…Essa região tem clima de transição e, por situar-se no alto curso do rio Mearim, apresenta um menor volume de água quando comparada com as áreas de baixadas das regiões noroeste e nordeste do estado. Ape- 13,30,31,32 . Por isso, é importante determinar com exatidão os tipos desses complexos presentes no Maranhão, pois não se pode subestimá-los, principalmente em virtude de sua presença freqüente, do desenvolvimento da endofilia e da capacidade de se alimentar no homem.…”

“…oswaldoi (Peryassú) is regarded as an efficient vector in Brazil (Branquinho et al 1996), and a secondary vector in Venezuela where it was found ELISA positive for P. vivax (Rubio-Palis et al 1992). The species has been reported biting man in Putumayo, where it is suspected to be involved in malaria transmission (Quiñones et al 2000).…”

Anopheles (Nyssorhynchus) benarrochi, An. (N.) oswaldoi, and An. (N.) rangeli are the most common anthropophilic mosquitoes in the southern Colombian state of Putumayo. Adult females are most commonly collected in epidemiological studies, and this stage poses significant problems for correct identification, due to overlapping inter-specific morphological characters. Although An. rangeli is easy to identify, the morphological variant of An. benarrochi found in the region and An. oswaldoi are not always easy to separate. Herein we provide a rapid molecular method to distinguish these two species in Southern Colombia. Sequence data for the second internal transcribed spacer (ITS2) region of rDNA was generated for link-reared progeny of An. benarrochi and An. oswaldoi, that had been identified using all life stages. ITS2 sequences were 540 bp in length in An. benarrochi (n = 9) and 531 bp in An. oswaldoi (n = 7). Sequences showed no intra-specific variation and ungapped inter-specific sequence divergence was 6.4%. Species diagnostic banding patterns were recovered following digestion of the ITS2 amplicons with the enzyme Hae III as follows: An. benarrochi (365, 137, and 38 bp) and An. oswaldoi (493 and 38 bp). This polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay provides rapid, accurate, and inexpensive species diagnosis of adult females. This will benefit future epidemiological studies and, as PCR amplification can be achieved using a single mosquito leg, the remaining specimen can be either retained as a morphological voucher or further used in vector incrimination studies. That An. benarrochi comprises a complex of at least two species across Latin America is discussed
