Schemas of female and male genitalia in the subfamily Criocerinae A plesiomorphic state of the endophallus and its genital coupling drawn based on Düngelhoef and Schmitt (2006) and Schmitt and Uhl (2015) B derived state of the endophallus observed in the subgenus Lema and its genital coupling drawn based on Matsumura and Akimoto (2009) and Matsumura and Yoshizawa (2010); the pocket is formed by an invagination of the endophallus membrane including sclerites (Matsumura et al. 2013). Light grey in the schemas of the male genitalia indicates the body cavity.
