Fine structure of spermatozoa of some labidognath spiders (Filistatidae, Segestriidae, Dysderidae, Oonopidae, Scytodidae, Pholcidae; Araneae; Arachnida) with remarks on spermiogenesis
TLDR
The present study reports on the spermiogenesis and spermatozoa of seven labidognath spiders: Filistata insidiatrix, the first cribellate spider whose spermatology is described electron microscopically, and others.
FORTUYNIA ATLANTICA SP . NOV . , A THALASSOBIONTIC ORIBATID MITE FROM THE ROCKY COAST OF THE BERMUDA ISLANDS ( ACARI : ORIBATIDA : FORTUYNIIDAE )

The affinities of mites and ticks: a review
TLDR
Previous hypotheses of mite affinities are reviewed to highlight important character sets which should be included in subsequent phylogenetic analyses, as well as useful areas for future investigations: particularly tagmosis and the nature of the gnathosoma.
Fine structure of the genital system in the bee parasite,Varroa jacobsoni (Gamasida: Dermanyssina) with remarks on spermiogenesis, spermatozoa and capacitation
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,
