Journal ArticleDOI
Copulatory dialogue: female spiders sing during copulation to influence male genitalic movements
TL;DR: Stridulation during copulation by the female of the spider Physocylus globosus, documented here for the first time, is common and noncoercive, thus permitting simple tests regarding its possible function.
Journal ArticleDOI
Cryptic female choice via sperm dumping favours male copulatory courtship in a spider.
TL;DR: Which of several variables associated with copulation correlated with paternity success in P. globosus when two males mate with a single female are determined and which variables may affect paternity via the mechanism of sperm dumping are inferred.
Journal ArticleDOI
Fine structure of male genital system and sperm in solifugae does not support a sister-group relationship with pseudoscorpiones (arachnida)
Gerd Alberti,Alfredo V. Peretti +1 more
TL;DR: The derived, simple-aflagellate structure of sperm in Solifugae and the similarity with sperm of Actinotrichida are confirmed, presenting results for two further species of another family (Ammotrechidae) from Argentina.
Journal ArticleDOI
Female control of mating sequences in the mountain scorpion Zabius fuscus: males do not use coercion as a response to unreceptive females
TL;DR: Analysis of premating behavioural patterns of virgin and inseminated females from natural or artificially interrupted matings of the mountain scorpion Zabius fuscus indicates that postmating sexual receptivity in females is not affected by other male characteristics such as body or spermatophore size.
Journal ArticleDOI
Evidence that Mating Plug is Related to Null Female Mating Activity in the Scorpion Vaejovis punctatus
TL;DR: A case in which the mating plug of the scorpion Vaejovis punctatus seems correlated with a reduction in female sexual receptivity is document, allowing us to hypothesize a sexual coevolutionary scenario inwhich the effectiveness of the plug to inhibit female remating may lie at the center of such interaction.
