The female genital tract ofVarroa jacobsoni is composed of a sperm-access system comprising paired solenostomes located between coxa III and IV, paired tubules, paired rami, an unpaired sperm duct, and an unpaired spermatheca. Another part of the female genital system is confined to egg development and oviposition. It is composed of an ovary (s.str.), in which oocytes mature, and a lyrate organ functioning as a nutrimentary structure. Both compartments, regarded as parts of the gonad, are… 
Fine Structure of the Female Genital System in Phytoseiid Mites with Remarks on Egg Nutrimentary Development, Sperm-Access System, Sperm Transfer, and Capacitation (Acari, Gamasida, Phytoseiidae)
TLDR
The ultrastructure of the sperm-access system, composed of paired solenostomes, major and minor ducts, emboli, calyces, and vesicles, is reported and functional aspects are discussed.
Ultrastructural Morphology of the Male and Female Genital Tracts of Psoroptes spp. (Acari: Astigmata: Psoroptidae)
TLDR
The structure of the male and female genital systems of the astigmatid mite Psoroptesovis (Hering) is described and similarities with other astigmatic mites belonging to Psoroptidia and Acaridia are discussed.
Ultrastructure of the male genital tract, spermatogenesis and spermatozoa of hattena cometis domrow (Acari: Gamasida: Ameroseiidae)
TLDR
The interpretation of the correlated evolution of components of gamasid reproductive systems is confirmed and the results compared with results obtained from other anactinotrichid Acari are compared and confirmed.
Female genital system of the folding‐trapdoor spider Antrodiaetus unicolor (Hentz, 1842) (Antrodiaetidae, Araneae): Ultrastructural study of form and function with notes on reproductive biology of spiders
TLDR
The genitalia of the female folding‐trapdoor spider Antrodiaetus unicolor are characterized by two pairs of spermathecae that are arranged in a single row and connected to the roof of the bursa copulatrix, where most of the secretion that composes the chorion of the egg is produced in the ovary.
Complexity, adaptations and variations in the secondary insemination system of female Dermanyssina mites (Acari: Anactinothrichida: Gamasida): the case of Afrocypholaelaps africana
TLDR
The functional morphology, complexity and variations of the sperm access system in Dermanyssina are discussed and correlated with the evolutionary biology of the group.
Ultrastructure investigation of the secondary insemination system of the gamasid mite Hattena cometis domrow (Acari: Anactinotrichida: Ameroseiidae)
TLDR
A description of the fine‐structure of the female secondary insemination system in the dermanyssine mite Hattena cometis is presented and it is suggested that some intermediate types might be revealed in future ultrastructure studies representing steps in the evolution of the inseminations in the Dermanyssina.
Female and male reproductive systems in the oribatid mite Hermannia gibba (Koch, 1839) (Oribatida: Desmonomata)
TLDR
The reproductive systems of both sexes of the oribatid mite, Hermannia gibba, are described and microorganisms colonize the oocytes of females, whereas in males they are present both between and within spermatocytes and sperMatids.
Fine Structure and Functional Morphology of the Spermatodactyl in Males of Heterozerconidae (Gamasida)
TLDR
Comparison of the ultrastructure and organization of the spermatodactyl in Heterozerconidae males with gonopods in other families among gamasid mites might help in better understanding their position in the group.
Sperm structure in Parasitidae mites (Parasitiformes: Mesostigmata: Gamasina)
TLDR
The ultrastructure of ribbon-type sperm in 14 genera of both subfamilies of the Parasitidae family is reviewed, finding a wide range of sperm dimensions and nucleus lengths, but basic external and internal structures were substantially constant across genera.

TLDR
The paired testes of the spider miteTetranychus urticae are divided in a part producing germ cells and a secretory portion with a vast lumen, characterized by the following features: invagination of the plasma membrane, degeneration of cell organelles, reduction in size and condensation of nucleus and cytoplasm.

TLDR
The paper presents the results of ultrastructural studies on the spermiogenesis in the mite, Pergamasus viator Halaŝkova, and discusses the modifications occuring in the course of spermatid maturation, which include a change of cell shape, modifications of its organelles and formation of new structures like the superficial layer of cellular processes.

TLDR
Waves of constrictions on the tail-like part of the spermatozoon and undulations of the cellular processes are considered to be involved in sperm motility.

TLDR
Because of the complicated transformation of the spermatide also the nucleus, the acrosome and the centrioles undergo extensive migrations being accomplished in the female.
