The Subgenus Persicargas (Ixodoidea: Argasidae: Argas)
The female Argas (P.) arboreus coxal organ consists of a nitration chamber, a tubular system, and an accessory gland that serves for passive fluid transport and fluid osmoregulation.
Bat ticks of the genus Argas (ixodoidea: Argasidae)
The surface structure and histology of the ventral paired grooves of Argas (Chiropterargas) boueti and A. (Carios) vespertilionis are described as seen by scanning electron microscopy (SEM) and the light microscope and the function is uncertain, but paired groves may assist in the defecation process.

The molting process of the adult tick spiracle is more simple than that of insects having specialised spiracular plates.
The Functional Morphology of Haemaphysalis Spiracles (Ixodoidea: Ixodidae)
Experimental CO2 and cyanide gas exposure provide evidence of a mechanism for opening and closing the spiracle and involving the ostial lip and atrial valve that appears to depend on hemolymph pressure and action of atrial and other body muscles.
Fine structure of the salivary glands of unfed male Dermacentor variabilis (Say) (Ixodoidea: Ixodidae).

In the granule-secreting alveolus, the presence of 3 types of secretory cells, each with morphologically distinct granular inclusions, confirms histological and histochemical observations on argasid salivary glands.
Ultrastructure of granule secretion in salivary glands ofArgas (Persicargas) arboreus during feeding
This granule secretion process in argasid ticks is rapid; not all of the secretory cells secrete during a single feeding and those that do remain intact enough for synthesis of new granules are used for repeated feedings.

Results show that the 3 cell types of Argas (Persicargas) persicus are not different steps in secretion of a single salivary substance, as believed by previous workers.
