The structure and surface morphology of the femaleNuttalliella namaqua spiracle are described with the aid of light and scanning electron microscopes. The spiracle, located posterolaterad to coxa IV, consists of a convex fenestrated plate lacking the marginal peritrime of ixodids, and a small, concave macula with a crescentic ostium enclosed by a lip. Ramifying pedicels around interpedicellular spaces are easily observed through the wide surface fenestrae. Below the ostium, a subostial space…

Nuttalliella namaqua (Ixodoidea: Nuttalliellidae): First Description of the Male, Immature Stages and Re-Description of the Female

This study addressed questions regarding the description of larvae, nymphae and males and resolved issues pertaining to female morphology and resolved differences in the original descriptions of N. namaqua.


The structure of the gland in Ixodes ricinus was examined using electron microscopy and the results are compared with the findings in previously studied species and possible functions of the glands are discussed.

Ticks parasitised feathered dinosaurs as revealed by Cretaceous amber assemblages

Direct and indirect evidence in 99 million-year-old Cretaceous amber is reported showing that hard ticks and ticks of the extinct new family Deinocrotonidae fed on blood from feathered dinosaurs, non-avialan or avialan excluding crown-group birds.

Publisher Correction: Ticks parasitised feathered dinosaurs as revealed by Cretaceous amber assemblages

The originally published version of this Article was updated shortly after publication to add the word ‘Ticks’ to the title, following its inadvertent removal during the production process. This has



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.

The molting process of the adult tick spiracle is more simple than that of insects having specialised spiracular plates.

Discovery of Nuttalliella namaqua Bedford (Acarina: Ixodoidea: Nuttalliellidae) in Tanzania and Redescription of the Female Based on Scanning Electron Microcopy

3 additional females, 2 from Tanzania, and one lacking data from the Dr. Paul Schulze collection are reported here 3 additional females belonging to the monotypic family Nuttalliellidae, previously known only from 15 female specimens from South-West Africa.

On the Structure of the spiracle of the tick, Ornithodoros moubata Murray

The most conspicuous feature of the spiracle of Ornithodoros moubata is the so-called cribriform plate. This is a massive crescent-shaped vesicle consisting of three layers; the underlying

The Structure and Function of the Spiracles of the Tick, Ornithodoros moubata Murray

The structure of the spiracle of Ornithodoros moubata is proposed, and how its function may be investigated by experiments is shown.

The structure of the Spiracles of the cattle tick, Boophilus microplus

The structures of the nymphal and adult spiracles of the tick, Boophilus microplus, have been examined by means of serial sections and a stereoscan electron microscope and the ecdysial process of the spiracles is shown to be basically similar to the ecology of certain insects such as scarabaeid larvae and the larvae of some Diptera-Cyclorrhapha.

An improved method for cleaning and preparing ticks for examination with the scanning electron microscope.

An improved cleaning method in which a common household glue is used to remove integumental debris from ticks, especially argasids, is reported.
