Males of many animals perform ‘copulatory courtship’ during copulation, but the possible reproductive significance of this behaviour has seldom been investigated. In some animals, including the spider Physocyclus globosus (Pholcidae), the female discards sperm during or immediately following some copulations. In this study, we determined which of several variables associated with copulation correlated with paternity success in P. globosus when two males mate with a single female. Then, by… 
Copulatory behavior in a pholcid spider: males use specialized genitalic movements for sperm removal and copulatory courtship
TLDR
This work investigates how copulation duration, pedipalp movements, and abdominal movements that males of the pholcid spider Holocnemus pluchei produce during copulation influence sperm removal and/or patterns of successful sperm transfer and suggests that males use alternating pedipalP movements to remove most of the rival sperm stored by mated females before sperm transfer.
Copulatory and Post-copulatory Sexual Selection in Haplogyne Spiders, with Emphasis on Pholcidae and Oonopidae
TLDR
Future attention to the behavior of both female and male, and to the possible dialogues during copulation, promises to be a valuable tool in understanding sexual interactions in these spiders.
Female wolf spiders exert cryptic control drastically reducing ejaculate size
TLDR
It is proposed that cryptic female control is a main factor driving males to strengthen sperm transfer, linked to post-copulatory sexual selection, affecting males' sperm transfer and the resulting sperm storage by females.
Copulatory behaviour increases sperm viability in female spiders
TLDR
It was found that females that stored sperm for 4 or 15 days showed no difference in sperm viability but had lower sperm viability compared with males, and males that performed a longer post-insemination behaviour had higher sperm viability inside the female.
Female Pygmy Squid Cryptically Favour Small Males and Fast Copulation as Observed by Removal of Spermatangia
TLDR
It is suggested that spermatangia removal after copulation by buccal mass elongation works as a CFC in Japanese pygmy squid, and females cryptically favoured small males and fast copulation.
Patterns of Sperm Transfer Behavior in a Pholcid Spider with Two Distinct Copulatory Phases
TLDR
The results show that sperm transfer occurs during phase I, that males transfer almost all sperm from their bulbs while the females store only 20% of that male amount, and there was no relation between the amount of sperm transferred or stored and the duration of the copulatory phases.
Cryptic Female Choice in Arthropods
TLDR
Assessing what is known and as yet unknown about the interface between CFC and Sfps and suggesting avenues for further research in this fascinating area of Diptera is concluded.
Sperm storage mediated by cryptic female choice for nuptial gifts
TLDR
This study confirms the prediction that the nuptial gift as a male signal is under positive sexual selection by females through cryptic sperm storage, and facilitates longer copulations and increased sperm transfer providing two different types of advantage to gift-giving in males.

Copulatory courtship and cryptic female choice in red flour beetles Tribolium castaneum
TLDR
Female perception of male copulatory courtship behaviour, rather than male behaviour per se, apparently governs the fate of sperm competing over fertilizations within the female, showing that copulatory Courtship is under selection by cryptic female choice.
COPULATORY BEHAVIOR, GENITAL MORPHOLOGY, AND MALE FERTILIZATION SUCCESS IN WATER STRIDERS
TLDR
By analyzing shape variation in male genital morphology, it is demonstrated that the shape of male intromittent genitalia was related to relative paternity success, the first direct experimental support for the suggestion that male genitalia evolve by postmating sexual selection.

TLDR
It is proposed that males have exploited a pre–existing female sensory bias to gain access to otherwise physically unreachable sperm in Calopteryx haemorrhoidalis asturica and shed light on the issue of the origin of female preferences in current models of sexual selection and on the evolution of genitalia via sexual selection.
Determinants of paternity success in the spider Pholcus phalangioides (Pholcidae: Araneae): the role of male and female mating behaviour
TLDR
It is suggested that in second matings, P PMs help to remove sperm from previous males, whereas in first matings a high number of PPMs enhances fertilization success, either due to numerical sperm competition or cryptic female choice.

TLDR
It is indicated that an aspect of sexual selection by female choice not considered by Darwin may be more important than previously appreciated and that the common practice in evolutionary studies of measuring male reproductive success by counting numbers of copulations may sometimes be misleading because of cryptic female choice during and after copulation.
Copulatory courtship signals male genetic quality in cucumber beetles
TLDR
The repeatability of stroking behaviour within males, variability between males and heritability between generations of copulatory stroking combine to provide females with a reliable and honest signal of the genetic quality of courting males.
Sperm ejection as a possible cryptic female choice mechanism in Odonata (Insecta)
TLDR
Using two zygopterans and one anisopteran, it is shown that females mate more than once, show a marked reduction in stored sperm, and that this is by ejection of sperm before to oviposition, which suggests that marked sperm reduction is common in this insect order.
Female control : sexual selection by cryptic female choice
TLDR
Cryptic female choice establishes a new bridge between sexual selection theory and reproductive physiology, in particular the physiological effects of male seminal products on female reproductive processes, such as sperm transport, oviposition, and remating.
Female feral fowl eject sperm of subdominant males
TLDR
It is shown that in female feral fowl most copulations are coerced, and that females consistently bias sperm retention in favour of the preferred male phenotype.
