Sensilla and secretory glands in the antennae of a primitive ant: Dinoponera lucida (Formicidae: Ponerinae).
Morphology of the antennae of the female workers of the ponerine ant Dinoponera lucida was examined by light and scanning electron microscopy. In several antennomers, we found secretory gland cells of class I and III. Class III gland cells release their secretion through single pores in the antennal surface, whereas class I secretory cells are seen as tall epidermal cells close to the cuticle. Both gland types have weak reaction for total proteins and neutral polysaccharides. Six distinct sensilla types were observed: trichodea, chaetica, campaniform, basiconica, placodea, and coeloconica. The possible sensory functions of these sensilla and the gland functions are discussed.
