The Subgenus Persicargas (Ixodoidea: Argasidae: Argas)
TLDR
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. Expand
Bat ticks of the genus Argas (ixodoidea: Argasidae)
TLDR
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 Functional Morphology of Haemaphysalis Spiracles (Ixodoidea: Ixodidae)
TLDR
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. Expand
A rickettsialike microorganism in the tick Ornithodoros savignyi: Observations on its structure and distribution in the tissues of the tick.

  • 1 August 1968
TLDR
Light and electron microscopy of the microorganism in infected tissues show close similarities in appearance and fine structure to certain Rickettsia and to other rickettsialike symbiotes naturally occurring in ticks and other arthropods. Expand
Structure of the nymphal spiracle and its formation in the pharate adult Haemaphysalis (Kaiseriana) longicornis neumann (ixodoidea: Ixodidae)

  • Biology, Medicine
  • Zeitschrift für Parasitenkunde
  • 5 July 1974
TLDR
The molting process of the adult tick spiracle is more simple than that of insects having specialised spiracular plates. Expand
The subgenus Persicargas (Ixodoidea: Argasidae: Argas): A. (P.) arboreus central nervous system anatomy and histology.
The anatomy and histology of the adult Argas (Persicargas) arboreus central nervous system are described and compared with these properties in other ticks. The single, integrated, central nerve massExpand
The subgenus Persicargas (Ixodoidea: Argasidae: Argas). 23. Fine structure of the salivary glands of unfed A. (P.) Arboreus Kaiser, Hoogstraal, and Kohls.
TLDR
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. Expand
Ultrastructure of granule secretion in salivary glands ofArgas (Persicargas) arboreus during feeding
TLDR
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. Expand
