“…These studies first became popular in the families Scarabaeidae and Lucanidae where head and/or thoracic horns and mandibles, respectively, are frequently exaggerated (for reviews of earlier studies and other families see Eberhard & Gutiérrez, 1991;Emlen & Nijhout, 2000;Emlen, Hunt & Simmons, 2005;Miller & Wheeler, 2005;Kawano, 2006). In recent years, static allometry studies have included many other beetle families, including Anthribidae (prothorax length; Mattos, Mermudes & Moura, 2014), Cantharidae (male genitalia; Bernstein & Bernstein, 2002), Dytiscidae (body size; Fairn, Alarie & Schulte-Hostedde, 2007a), Gyrinidae (body size; Fairn, Alarie & Schulte-Hostedde, 2007b), and Leiodidae (mandibular horns; Miller & Wheeler, 2005).…”
