Gross morphology, histology, and ultrastructure of the alimentary system of Ricinulei (Arachnida) with emphasis on functional and phylogenetic implications
Ricinuleid functional mouthparts are the cucullus, the chelicerae, the pedipalps, and the labrum. These structures are movably jointed to the rest of the prosoma, most likely protruded upon
Mouthparts of a tydeid mite: an ultrastructural and functional investigation
TLDR
The gnathosoma of a tydeid mite (Tydeus sp.) shows the subcapitulum and the cheliceral segments not fused to each other though closely appressed, and some sensorial structures associated with the mouthparts components have been observed and described.
FUNCTIONAL MORPHOLOGY OF MECHANORECEPTORS IN ASTIGMATIC MITES
TLDR
Mechanoreceptors include setiform sensilla and cupules, which are thought to be cuticular receptors that register strains in the cuticle caused by gravity, vibrations, movements of the mite, and/or internal changes in pressure.
Morphological, ultrastructural and functional adaptations of the mouthparts in cheyletid mites (Acari: Actinedida: Cheyletidae)
TLDR
A three-dimensional reconstruction of the cheyletid family is provided with dynamic evidences of the functioning and shows peculiar adaptations to this feeding behavior of these predatory and parasitic species.
COmpARATIvE ANALySES Of ThE INTERNAL ANATOmy AND fUNCTIONAL mORphOLOgy Of ThE ELEUThERENgONA ( ACARI , TROmbIDIfORmES )
TLDR
The study summarizes data on the internal anatomy of the mites belonging to the parvorder Eleutherengona mainly based on the families Tetranychidae, Cheyletidae, Syringophilidae, Myobiidae, and Demodicidae to reveal common features of the Eleutheresngona as well as possible phylogenetically informative characters in particular families.
Mouthparts of Tarsonemus nodosus Schaarschmidt, 1959 (Acari: Tarsonemidae): fine structure and functional morphology
TLDR
The mouthparts of Tarsonemus nodosus Schaarschmidt, 1959 were studied by means of transmission and scanning electron microscopy and a functional interpretation is proposed and compared with that of other phytophagous mites.
Confocal microscopy reveals uniform male reproductive anatomy in eriophyoid mites (Acariformes, Eriophyoidea) including spermatophore pump and paired vasa deferentia
TLDR
Three-dimensional reconstructions based on autofluorescence show that a thin-walled genital chamber is usually situated in a transverse plane and precisely copies the shape of the spermatophore, whereas the distal ductus ejaculatorius possesses well-developed musculature, appearing in 3D reconstructions as a hollow sphere with three apertures.
COMPARATIVE MORPHOLOGY, ULTRASTRUCTURE AND FUNCTIONS OF THE EXCRETORY ORGAN (POSTVENTRICULAR MIDGUT) IN THE PARASITENGONA (ACARIFORMES)
TLDR
The excretory organ of terrestrial mites Leptotrombidium orientale, Euschoengastia rotundata, and Hirsutiella zachvatkini as well as of water mites Teutonia cometes and Piona carnea in different developmental stages was studied using transmission electron microscopy and on semi-thin sections.
Peculiar salivary glands in a silk‐producing mite Bakericheyla chanayi (Cheyletidae)
TLDR
The detection of axon profiles in the gland body suggests a neural control for the glandular cell function, and two possible ways of secretion are suggested: 1) exocytosis into the acinar cavity and 2) direct passage via the central processes.
Suboral fork: a newly discerned gnathosomal structure from the proboscis of eriophyoid mites (Acari, Eriophyoidea)
TLDR
A newly discerned structure, the suboral fork, situated in the ventral part of the proboscis was discovered, which presumably determines the site of piercing and functions in a similar way to the pressure foot of a sewing machine which controls the movements of a needle in diptilomiopids.

Morphology of the mouthparts of several species of phytophagous mites.
TLDR
The morphology of the mouthparts of 5 families of phytophagous mites was studied, finding the terminal palpal segment is not pad-like but elongated, suggesting these mites feed in a different manner than eriophyid mites.
Ultrastructure of the excretory tubes of the mite Macrocheles muscaedomesticae (Mesostigmata, Macrochelidae) with notes on altered mitochondria
TLDR
The fine structure of the excretory tubes of the mesostigmatid mite Macrocheles muscaedomesticae were investigated and it is suggested that they represent part of a normal process of mitochondrial degeneration.
Fine structure and function of the prosomal glands of the two-spotted spider mite, Tetranychus urticae (Acari, Tetranychidae)
TLDR
The tracheal gland may produce a secretion which facilitates the movement of the fused chelicerae and the stylets, and the coxal organ may add a liquid, ion-rich secretion.

TLDR
An open communication between ventriculus and excretory organ has been demonstrated in two further groups of trombidiform mites and a new terminology is proposed: 1st, 2nd, 3rd, 4th podocephalic gland, by which the latter corresponding to the coxal gland is proposed.
Trichobothrien und tastborsten der milbe Microcaeculus (Acari, Prostigmata, Caeculidae)
TLDR
It may be suggested that two different directions may be distinguished by each sensillum, as Apparently, the bristles may be bent in every direction, but at least the trichobothria show two favorite directions of bending.
Observations on the Morphology and Behavior of the Filbert Rust Mite, Aculus comatus (Prostigmata: Eriophyoidea) in Oregon
TLDR
It is suggested that late summer population decline of A. comatus in 1972 was the result not only of loss through protogyne dissemination and predation, but also through increased water stress in the host engendered by a hot dry growing season.

TLDR
An investigation of the biology and anatomy of the mite family Bdellidae (Trombidiformes) included a study of the mating behaviour and the genital system of ten species, including the complicated male genital system and spermatophores of species of all four subfamilies.
Morphology and functional anatomy of Demodex folliculorum (Simon) of man
TLDR
An extended synopsis is appended to provide an overview of structural, functional and developmental features of D. follicitlorum which should serve as analogues for other members of this genus.
Fine Structure of Aceria tulipae (Acarina: Eriophyidae)
TLDR
The integument, alimentary system, and hemolymph are similar to those reported for higher arthropods, although the circulatory system did not appear to have cardiac muscle or aortic systems present.
