“…Cobweb 81 spiders have long served as models in the study of evolution of 82 sociality (Aviles, 1997;Lubin and Bilde, 2007), containing over half 83 of all social spiders in three of its genera: Theridion Walckenaer, 84 1805 , Parasteatoda Archer, 1946 (Lubin, 85 1995), and especially Anelosimus Simon, 1891 (Aviles et al, 2000;86 Aviles and Purcell, 2011;Aviles and Salazar, 1999;Aviles and 87 Tufino, 1998). Cobweb spiders are also the subjects of study on a 88 range of other topics such as web architecture (Barrantes and 89 Eberhard, 2010; Barrantes and Weng, 2007;Eberhard, 1979, 90 1981; Eberhard et al, 2008aEberhard et al, , 2008bJorger and Eberhard, 2007), 91 morphology (Agnarsson, 2004;Coddington, 1989;Knoflach and 92 Pfaller, 2004), kleptoparasitism (Agnarsson, 2003b;Cangialosi, 93 1990aCangialosi, 93 , 1990bGrostal and Walter, 1997), myrmecophagy 94 (Eberhard, 1979), extraordinary sexual behavior (Knoflach and 95 van-Harten, 2001;Knoflach and van Harten, 2000) and many 96 others. For a comparative analyses of any of these intriguing traits 97 up-to-date phylogenetic analyses are essential (Agnarsson et al, 98 2006(Agnarsson et al, 98 , 2007aAgnarsson and Coddington, 2008;Eberhard et al, 99 2008a; Samuk and Aviles, 2013;Samuk et al, 2012).…”
