Secondary malaria vectors in western Kenya include novel species with unexpectedly high densities and parasite infection rates

Table 1 Morphologically identified adult Anopheles samples by site based on sampling method in Kisumu County

Site	Vector type	Primary vector				Secondary vectors
	Anopheles species	An. gambiae s.l		An. funestus s.l		An. coustani		An. pharoensis
	Sampling method	Total	Female/trap/night	Total	Female/trap/night	Total	Female/trap/night	Total	Female/trap/night

Primary vectors sampled (An. gambiae (s.l.) and An. funestus (s.l.)) are also included to demonstrate the relevance of secondary species in context with the overall vectors present. Capture rates are standardized by female specimens per trap per night
