FERNANDEZ L, Roberto; SCHOELER, George  and  STANCIL, Jeffrey. Presencia de Anopheles (Nyssorhynchus) benarrochi en áreas de selva con transmisión malárica. Rev. perú. med. exp. salud publica [online]. 2004, vol.21, n.4, pp.217-222. ISSN 1726-4634.

Objective: Determine the presence of An. (Nys.) benarrochi in those malaria transmission areas where it is often identified as An. evansae. Material and methods: Collections were conducted in San José (Pucallpa), Muniches and Andoas (Alto Amazonas), localities where malaria transmission occurs. Mosquitoes were reared in the laboratory where larval and pupal exuviae were preserved along with corresponding adults specimens, dissection of male genitalia and biometry of male and female adult mosquitoes was also conducted. Results: The presence of An. benarrochi in the above localities was confirmed with both field collected adults and laboratory-reared specimens. Considerable morphological variability was noted in the laboratory-reared specimens, which has likely contributed to previous incorrect identifications. Conclusions: Based on these studies, the species identified as An. (Nys.) evansae correspond to An. (Nys.) benarrochi, in these malaria endemic areas. Morphological variability makes identification of similar species difficult, thus it is necessary to conduct thorough studies to know local fauna of anophelines.
