The Finer Structure of the Galeal Lamella in Adult Mosquitoes

Abstract

THE maxilla of the adult mosquito is a reduced structure in that the cardo and lacinia are almost lost, and the stipes is embedded below the alimentary canal. The functional maxilla is a lancet-like galea consisting of a chitinized rod with a trough-shaped membranous lamella on its outer edge. This lamella has been described in Anopheles maculipennis as possessing fine anastomosing striations and bearing at its distal extremity small, backwardly pointing teeth1. The piercing action of the maxillary galea has been described elsewhere2.
