Molecular phylogeny of acariform mites (Acari, Arachnida): strong conflict between phylogenetic signal and long-branch attraction artifacts.
Acariformes (one of the two main lineages of Acari) represent an exceptionally diverse group of Arachnida. We performed first comprehensive phylogenetic analysis of Acariformes using sequence dataExpand

Morphological adaptation for precopulatory guarding in astigmatic mites (Acari: Acaridida)
Abstract Precopulatory guarding of female tritonymph is common in feather mites, Proctophyllodes stylifer and P. picae (Proctophyllodidae), and is assumed to be present in psoroptid skin parasites,Expand

Spermatogenesis and postinseminational alterations of sperm structure in a Sarcoptid mite, Notoedres cati (Hering) (Acari, Acaridida, Sarcoptidae)
Ultrastructural features of sperm formation and their postinseminational alterations in a sarcoptid mite, Notoedres cati, were described. In the testes, the spermatogonia, spermatocytes, spermatidsExpand
