ZusammenfassungDas Verhalten, die Samenübertragungsweisen und die Spermatophoren verschiedener Arten von Pseudoscorpionen wurden beobachtet und beschrieben.Alle Pseudoscorpione setzen Spermatophoren ab, denen die Weibchen die Spermien entnehmen. Das Verhalten bei der Samenübertragung ist bei den verschiedenen Arten unterschiedlich; es läßt sich eine Evolution von einfachen zu komplizierteren Vorgängen feststellen.Das Verhalten vonChthonius tetrachelatus, Chthonius ischnocheles undNeobisium… 
Zur Ethologie von Trithyreus Sturmi Kraus (Arachnida, Pedipalpi, Schizopeltidia)
TLDR
Die okologischen Anspruche von Trithyreus Sturmi Kraus, einer kleinen kolumbianischen Art of Geiselskorpionen, werden kurz charakterisiert.
Funktionsanatomie der genitalorgane und fortpflanzungsverhalten bei den männchen der Erythraeidae (Acari, trombidiformes)

TLDR
The homology of male accessory reproductive organs in prostigmatic Trombidiformes is discussed, as well as the phylogenetic aspect of indirect sperm transfer without a previous mating.
Double spermatogenesis in Chelicerata
TLDR
This further, although less evident, case of probable dichotomous germ cell development is discussed with respect to the controversial phylogenetic‐systematic relationships between Uropygi (Thelyphonida and Schizomida), Amblypygi, and Araneae.
Review Canalized pathways of change and constraints in the evolution of reproductive modes of microarthropods
TLDR
It is shown how in a changed environment few behavioural changes have initiated an evolutionary sequence which has finally led convergently in several lineages to semi-direct or direct sperm transfer and to a massive repatterning of the original reproduction pattern.
Spermatophore formation in the pseudoscorpion Chthonius ischnocheles (Chthoniidae)
TLDR
A functional interpretation of spermatophore formation in Chthonius ischnocheles is based on evidence from a morphological study of the genital atrium, the associated accessory glands and the musculature and biochemical analyses of one gland (posterior dorsal) and its secretion and the behaviour of males during this process.
The Phylogeny and Classification of the Pseudoscorpionida (Chelicerata : Arachnida)
TLDR
A new pseudoscorpion classification is proposed with two new suborders, Epiocheirata and IocheIRata, based upon a cladistic analysis of relationships within the order, and the systematic position of the Devonian family Dracochelidae is discussed.
Cheliferoid pseudoscorpions (Arachnida, Chelonethi) from the Lower Cretaceous of France
TLDR
A new genus is described from the Lower Cretaceous amber of Archingeay (Charente-Maritime, France), characterized by having gaping chelal fingers, elongate tarsal setae on leg I and the basal position of the tactile seta on the tarsus of legs III and IV.
A comparative study of the male genitalia of the Cacodemoniini (Pseudoscorpiones: Withiidae)
TLDR
The male genital armature of the Cacodemoniini is characterized and proposed homology statements for these structures based upon their morphological correspondence are proposed to lay the groundwork for phylogenetic testing of homologies and may allow a better understanding of the formation of the spermatophore, given that it is molded by the genital armatures.
Vicariance in a Cryptic Species Pair of European Pseudoscorpions (Arachnida, Pseudoscorpiones, Chthoniidae)
TLDR
Although multivariate analyses suggest specific separation, there is only one unequivocal character for discrimination: the presence or absence of a single isolated tooth on the moveable finger of the chelicerae and it is concluded that the species rank of the two morpho- species is justified.
Supralittoral pseudoscorpions of the genus Garypus (Pseudoscorpiones : Garypidae) from the Indo-West Pacific region, with a review of the subfamily classification of Garypidae
TLDR
The species-level revision of Garypus provides evidence for at least 14 species, most of which are known from only single localities, and the relationships of the various garypid genera are tested using a molecular analysis and an assessment of their morphology.

On the Origin of Mating Behavior in Spiders
TLDR
From a comparative survey of the mating habits of those arachnids for which the facts are known, it is suggested that the proto-spiders may have transfered the sperm to the female by way of a spermatophore which they deposited on the substratum.
