“…At the end of Jurassic and the beginning of the Cretaceous, a strong decrease in the diversity of hangingflies was observed (Kopeć et al 2016). Today, the Bittacidae comprises c.200 species in 19 genera (Penny 1997;Collucci & Amorim 2002;Huang & Hua 2005;Cai et al 2006;Bicha 2007Bicha , 2011Petrulevičius et al 2007;Hua et al 2008;Tan & Hua 2008a, b, 2009aChen & Hua 2011;Chen et al 2013;Garcia-Garcia & Cadena-Castañ eda 2015), are the second most abundant family of extant scorpionflies after Panorpidae.…”
