Abstract
To examine the distribution pattern of Anopheles philippinensis and An. nivipes, mosquitoes belonging to An. philippinensis/nivipes group were collected from five sites in north-east Indian state of Assam and its adjoining areas and identified. Presence of both An. philippinensis and An. nivipes, with predominance of the latter taxon, was recorded with conformity on the basis of pupal paddle characteristics. Based on adult wing characters, 91.4% specimens were identified as An. philippinensis and 8.6% as An. nivipes with gradually increasing proportion of An. nivipes in westwardly direction. An. philippinensis/ nivipes was noted to be mid night biter, mainly exophagic and exclusively exophilic. Of the two species, An. philippinensis appears to be mostly anthropophilic and available in broken forest areas whereas An. nivipes seems to be mostly zoophilic and generally found in ecotone zones in plains areas.
