  author={Andrey B. Shatrov and Naina I. Kudryashova},
Abstract. The modern classification of trombiculid mites from the family Trombiculidae (Acariformes: Parasitengona) is briefly reviewed on the subfamily and tribe level based on the larval characters. Some taxonomical and evolutionary aspects are briefly discussed. The family Trombiculidae is divided into four subfamilies: Leeuwenhoekiinae — Apoloniinae — Trombiculinae — Gahrliepiinae, from which Leeuwenhoekiinae should be placed at the base and Gahrliepiinae at the top of phylogenetic tree… 

Host-associated differences in morphometric traits of parasitic larvae Hirsutiella zachvatkini (Actinotrichida: Trombiculidae)

The knowledge of larval morphology, including intraspecific variation of metric characters, supported by molecular and host range data, places H. zachvatkini among the most comprehensively defined members of Trombiculidae.

Evidence for co-invasion events: different chigger species (Actinotrichida, Trombidioidea: trombiculidae) share a host

Evidence is provided for 25 new cases of co-parasitism of chigger mites on rodent hosts (Myodes glareolus, Apodemus flavicollis, Apidemus agrarius) accounting for 8.6% of all host-Parasite associations observed in this study.

Not Only Leptotrombidium spp. an Annotated Checklist of Chigger Mites (Actinotrichida: Trombiculidae) Associated with Bacterial Pathogens

A variety of so far detected bacteria, including novel species, along with the mites’ vast geographical distribution and parasitism on differentiated hosts, indicate that revealing of more cases of Trombiculidae-pathogens association is highly probable, especially utilizing the newest techniques enabling a large-scale bacterial communities survey.

Parasitism, seasonality, and diversity of trombiculid mites (Trombidiformes: Parasitengona, Trombiculidae) infesting bats (Chiroptera) in Poland

It is argued that the identification of the parasitic larvae (chiggers) using morphological characters does not address the question of actual species boundaries, which, in turn, affects the inferences about host specificity and host range.

Host-parasite association in trombiculid mites (Actinotrichida: Trombiculidae) of temperate zone - the case of Hirsutiella zachvatkini (Schluger, 1948); are we dealing with prolonged contact with the host?

An increase in intensity observed from the onset of appearance of larvae on hosts, through autumn and winter months, indicates a prolonged contact with hosts, aimed at synchronisation of life cycle, conditioned by food resources available for active postlarval forms and constitutes a strategy enabling larvae to survive the unfavourable winter conditions.

Revision of the African chigger genus Austracarus (Acariformes: Trombiculidae: Leeuwenhoekiinae)

The monotypic genus Austrombicula Lawrence, 1949 was synonymized with Austracarus and an updated diagnosis and a key to species ofAustracarus are provided.

Host-Parasite Associations between Bats (Mammalia: Chiroptera) and Chiggers (Trombidiformes: Trombiculidae) — A Review and Checklist

Abstract. The host-parasite associations between bats and chiggers are re-traced; the checklist of reported pair-wise combinations contains records originating from all zoogeographical regions. The

The prostigmatid mite fauna on herps from the Cuatro Cienegas Basin include nine new records of mites for the study area and eight new host records including the first records of parasiticmites for five host species.

Uncommon record of a whip spider (Amblypygi: Charinidae) parasitized by a chigger mite (Parasitengona: Trombiculidae: Leeuwenhoekiinae)

A mite larva of the genus Leeuwenhoekia Oudemans parasitizing an individual of Charinus iuiu Vasconcelos & Ferreira found in a cave of the state of Bahia, Brazil is reported.

Description of Blankaartia shatrovi n. sp. (Acari: Trombiculidae) From Brazil

The presence of this genus of chigger mite in Brazil for the first time is reported, including the first report of Blankaartia sinnamaryi (Floch and Fauran) and the description of a new species of BlANKAartia collected from birds (Order Passeriformes).



[The origin of parasitism in trombiculid mites (Acariformes: Trombiculidae)].

It is shown that parasitism in this group of trombidiform mites is a relatively young historical phenomenon and was formed after their ontogenesis had differentiated into active and quiescent stages, and the character of individual development is much more important than the phase parasitism.

Larval and nymphal mites (Acarina; Trombiculidae) from Ceylon and the maldive islands

During five months spent in Colombo and on the Maldive Islands a large number of small mammals and birds were examined for larval Trombiculinae.

Endoparasitic mites of the genus Endotrombicula Ewing, 1931 (Acari: Prostigmata: Parasitengona: Trombiculidae) from African and Madagascan anurans, with description of a new species.

The geographic distribution of Endotrombicula, restricted to Africa, the Arabian Peninsula and Madagascar, suggests that these mites invaded Madagascar from the African continent quite recently, possibly accompanied by its EndotRombiculidae parasites.

New species and new records of chiggers (Acarina: Trombiculidae) from Texas

Three new species of chiggers are described from Texas: Euschoengastia eadsi from rabbits, Trombicula breviseta from a mouse, and Peromyscus eremicus from the bat Mormoops megalophylla.

Records of ectoparasites occuring on amphibians are exceedingly rare, and except for the occasional reports of parasitism of frogs by tropical ticks, are all but nonexistent. However, at least one

A list of Venezuela chiggers, particularly of small mammalian hosts (Acarina: Trombiculidae)

Of 86 described forms, 49 are new for Venezuela; the remaining undescribed taxa are coded for purposes of this report and a classified host-parasite list is appended.

Occurrence of Trombiculid Mites on Arthropods

The following records of three species of trombiculids parasitizing arthropods in Malaya are of considerable interest, and it is hoped that this note may stimulate more attention to this unexpected source.

Stylostome formation by Leptotrombidium mites (Acari: Trombiculidae).

The modes of stylostome formation by larvae (chiggers) of Leptotrombidium intermedium, L. fletcheri, and L. deliense in parasitized mouse skin were studied histologically in relation to their capacity to transmit Rickettsia tsutsugamushi to discuss the possible importance of stylstome characteristics to the transmission of rickettsial organisms.

Interest in a possible pest chigger of man was aroused in the fall of 1958 when a mite was removed from a welt on the arm of a woman living near MacDonald Forest (11 km N Corvallis, Benton County,
