Males and females of Cryptocercus punctulatus possess tergal glands which differ in position, size, morphology, and chemical composition of their secretions. Ultrastructural studies reveal the presence of class 1 and class 3 glandular units interspersed throughout the glands; class 3 glandular units are 30 times as numerous as in the female, but no cytological difference was found between the sexes. The morphology of the tergal glands is characterized by the occurrence of a subcuticular space reservoir, a dense tracheal system, and a thick collagenous layer instead of the typical basement membrane. Comparison with the termite abdominal gland system indicates a great similarity in the fine structure. The biological function of the tergal glands is discussed.
