Resumo: The grooved pegs also referred to in the literature as type A3 setae, thornshaped hairs, pegs, and sensilla basiconica of female Aedes aegypti (L.) are described. Externally the sensillum appears as a short, thick-walled, non-articulated peg with usually 12 grooves in the wall and bearing one terminal pore. Usually three, occasionally four or five, neurons with unbranched dendrites innervate each peg. The dendrites are encased in a prominent cuticular sheath from the ciliary region to the tip of the peg. Three sheath cells are associated with each sensillum. Although the grooved pegs have the structure commonly associated with contact chemoreceptors they function exclusively in the reception of air-borne stimuli
