Abstract

RUBIO-PALIS, Yasmin et al. First record of Anopheles (Nyssorhynchus) oswaldoi B y Anopheles (Nys.) albi-tarsis F from the Caura river basin, Bolívar State, Venezuela. Bol Mal Salud Amb [online]. 2013, vol.53, n.1, pp.68-72. ISSN 1690-4648.

Anopheles  albitarsis  F  and  Anopheles  oswaldoi  B were  first  recorded  from  collections  in  Sucre  and  Cedeño  Municipalities, Bolivar State. Morphometric analysis of dark  and pale spots on wing Costa and hind tarsomeres of adult females, showed that the range of variation for An. albitarsis  F are within the reported ranges for An. marajoara sensu latu For An. oswaldoi B the range of variation are within the ranges reported for An. oswaldoi s.l., An. oswaldoi sensu stricto from  Brazil and An. konderi. DNA mitochondrial analysis (Barcode region 658 bp) showed 3.2% of genetic divergence between  An. oswaldoi B and An. oswaldoi s.s., while this divergence  was 5.2% between An. albirtarsis F and An. marajoara s.s. Both these values are above the proposed limits for species  delimitation.  

Keywords : Anopheles oswaldoi B; Anopheles albitarsis F; species complex; malaria; Venezuela.
