Abstract
  • Glyptholaspis americana (Berl.), G. confusa (Foa) and deutonymphal Parasitus sp. were studied to determine the function of the tritosternum. Studies were conducted on feeding, cleaning, temperature and humidity sensitivity using intact individuals and individuals whose tritosterna had been surgically removed. The tritosternum was found to have two functions: 1) As a cleaning device to keep the deutosternal groove, deutosternal teeth and hypostome free of debris; 2) As a fluid-conserving device while feeding, being used in conjunction with the deutosternal groove; Sagittal and transverse serial sections were made to determine the structure of the tritosternum. The tritosternum was found to be discontinuously hollow, typically semi-circular in cross section, and with a bichambered base. The tritosternal base possesses two bands of muscle, each innervated by a tiny nerve.
