The male pseudoscorpion Serianus sp. n. deposits spermatophores without mating, but only when females are present. It marks a path to the spermatophore with silken threads produced in an endodermal gland, which is homologous to the rectal pocket in males and females of other species and in the female of the same species. 

Topics from this paper

Mating Behavior and Spermatophore Morphology of the Cave Pseudoscorpion Maxchernes iporangae (Arachnida: Pseudoscorpiones: Chernetidae)
TLDR
The mating behavior of the cave pseudoscorpion Maxchernes iporangae Mahnert & Andrade, 1998 (Chernetidae), was studied under laboratory conditions and consecutive mating was not observed between a female and the same or another male. Expand
Beobachtungen zur fortpflanzungsbiologie und zum verhalten der geißelspinne tarantula marginemaculata C. L. Koch (Chelicerata, Amblypygi)
The „social” behaviour of T. m. includes ritualized fights. Sperm transfer is achieved by means of a spermatophore deposited on the ground and by the male pulling the female over it. The behaviourExpand
Mating and spermatophore morphology of water mites (Acari: Parasitengona)
TLDR
Morphological features of spermatophores that improve physical stability, probability of females taking up sperm and resistance against osmotic stress are discussed and implications of mating behaviour and sperMatophore morphology for phylogenetic relationships within water mites and between this group and terrestrial Acari are presented. Expand
Mating behaviour and spermatophore morphology: a comparative test of the female-choice hypothesis
TLDR
The results uphold Eberhard's conclusion that the lock-and-key hypothesis does not explain the distribution of spermatophore complexity among taxa; however, they do not clearly support female choice as an alternative explanation. Expand
Indirect sperm transfer in arthropods: behavioral and evolutionary trends.
  • H. Proctor

TLDR
The morphology and physiology of indirectly transferred spermatophores have been shaped by environmental factors as well as biological ones, and they may provide useful phylogenetic characters. Expand
Vergleichende Untersuchungen zur Fortpflanzungsbiologie der Pseudoscorpione II
Das Verhalten, die Samenubertragungsweisen und die Spermatophoren verschiedener Arten von Pseudoscorpionen wurden beobachtet und beschrieben.
Sexual Behavior, Sexual Interference and Sexual Defense in the Salamanders Ambystoma maculatum, Ambystoma tigrinum and Plethodon jordani
TLDR
A hypothesis is proposed which relates the evolution of courtship speed, spermatophore number and sexual defenses to the length of the courtship season, the probability of intrusion by rival ♂ ♂ and the sexual receptivity of the ♀. Expand

Silk from Crickets: A New Twist on Spinning
TLDR
Spectra obtained from micro-Raman experiments indicated that the silk is composed of protein, primarily in a beta-sheet conformation, and that fibers and films are almost identical in terms of amino acid composition and secondary structure. Expand
THE ORIGIN OF THE SPINNING APPARATUS IN SPIDERS
TLDR
Two hypotheses are proposed which are consistent with the conclusion that silk in spiders evolved for reproductive needs (the spermatophore‐sperm web and egg sac hypotheses). Expand
