From: Antennal sensilla of two female anopheline sibling species with differing host ranges
Female head (ventral view). Scanning electron micrograph showing the sensory appendages of an adult female An. gambiae s.s. Eyes, antennae, and maxillary palps occur in pairs, although the second palp is hidden below the proboscis in this micrograph. The proboscis is a single appendage that encloses the blood-feeding stylets, which appear as ribbon-like tentacles here. At the distal end of the proboscis is the labellum, or labellar lobes. The gross morphologies of the appendages are essentially identical in An. quadriannulatus females.
