The fine structure of glandular units on the antennae of two species of the parasitoid, Aleochara (coleoptera : staphylinidae)

Abstract

The morphology of porous structures, common to the antennae of both males and females of two species of Aleochara, with similar lifestyles, is described. The ultrastructure of the underlying cells and their associated canals suggests a glandular function. These probable glandular units are monocellular. A canal, with microvilli at its base, connects to pores on the external surface of the antenna. Some of the possible functions of such glands are discussed.
