Studies on the Johnstonianidae (Acari, Parasitengona)

چکیده
THE SUBFAMILY Johnstonianinae Thor 1935 (Trombidiidae) was established to include Johnstoniana George 1909 and related genera. The only comprehensive treatment of the group was published by Thor and Willmann (1947) who included eight species in the genera Centrotrombidium Kramer 1896, Johnstoniana, Diplothrombium Berlese 1910, Myrmicotrombium Womersley 1934, and Hirstithrombium Oudemans 1928. The present study was undertaken with a view to placing the systematics of the Johnstonianinae on a sound morphological basis, and to detGrmine the relationship of the group to other terrestrial Parasitengona. It soon became apparent that the mites included in the Johnstonianinae differed so significantly from other terrestrial Parasitengona that they could not logically be retained within the family Trombidiidae Murray 1877. The differences are much greater than those which have been cited, for example, to establish Trombiculidae Ewing 1944 as a family separate from the Trombidiidae. The group is therefore raised to family rank with Johnstoniana George 1909 as the type genus. Interest in the group was stimulated by numerous indications that this is perhaps the most primitive existing family, terrestrial or otherwise, within the Parasitengona. The indications of this are of ecological, behavioral, and morphological nature.

متن کاملThe little known genus Forania (Acari, Prostigmata, Erythraeidae)
Forania (Acari: Parasitengona: Erythraeidae) is a poorly known genus parasitic on ants, recorded only twice and not since 1930. In the present work, we re-describe the only described species, Forania mentonensis (André). Some drawings and technical information of the types are published for the first time. A new specimen captured from the south of Spain is described as Forania sendrai sp. nov. ...
متن کاملConfocal microscopy applied to water mite taxonomy with the description of a new genus of Axonopsinae (Acari, Parasitengona, Hydrachnidia) from Central America
Vagabundia sci n. gen. n. sp. of the subfamily Axonopsinae is proposed and described. Confocal Laser Scanning Microscopy, not previously applied to water mite taxonomy, allowed the acquisition and posterior processing of clean optical slices. The new species is compared to other mites that have been described as ‘Axonopsella-like’. Vagabundia sci n. sp. is named after the Science Citation Index...
متن کاملEndoparasitic mites of the genus Endotrombicula Ewing, 1931 (Acari: Prostigmata: Parasitengona: Trombiculidae) from African and Madagascan anurans, with description of a new species.
A sample of over 6,000 specimens of frogs belonging to about 120 species of all families occurring in West Africa and Madagascar were screened for parasitic mites. Three species of Endotrombicula Ewing, 1931 were found in representatives of two African and two Madagascan frog families. All Trombiculidae found in African frogs belonged to Endotrombicula pillersi (Sambon, 1928), whereas in Madaga...
