Morphological phylogeny of cobweb spiders and their relatives (Araneae, Araneoidea, Theridiidae) (2004, background): “Among the most fascinating discoveries made in these studies is voluntary loss of the male palp (the intromittent organ), single palp copulation, and obligatory mate consumption in Tidarren Chamberlin & Ivie, 1934 and Echinotheridion Levi, 1963 (Branch, 1942; Knoflach & van-Harten, 2000, 2001; Knofl”
Genital damage in the orb-web spider Argiope bruennichi (Araneae: Araneidae) increases paternity success (2007, background): “In the species Tidarren argo, males even show a more bizarre behavior: males leave the whole pedipalp attached to the female’s genital organ and it is discussed that it acts as a temporary mating plug ( Knoflach and van Harten 2001 ).”
Risky mate search and male self-sacrifice in redback spiders (2003, background): “Although possible cases of male self-sacrifice have been identified in other spiders (Blanke, 1975; Grasshoff, 1964; Knoflach and van Harten, 2000, 2001; Sasaki and Iwahashi, 1995), to date, the net effect of cannibalism on male fitness has not been assessed in any sacrificial species ( Johns and ”
Safer sex with feeding females: sexual conflict in a cannibalistic spider (2005, background): “Interestingly, a high incidence of pedipalp damage after mating has also been found in other highly sexually cannibalistic species (Foellmer and Fairbairn, 2003; Knoflach and van Harten, 2001; Schneider et al., 2001), including the redback spider, Latrodectus hasselti, where pedipalp damage has be”
