“…In insects, including Hymenoptera, characteristics obtained from the spermatozoa structure are used in phylogenetic studies (Baccetti, 1970;Dallai, 1974;Jamieson, 1987;Quicke et al, 1992;Jamieson et al, 1999). The morphology of the Hymenoptera spermatozoa is known in various groups Quicke, 1999a, b, 2000;Lino-Neto et al, 1999, 2000aLino-Neto and Dolder, 2001b;Zama et al, 2005bZama et al, , 2007Mancini et al, 2006Mancini et al, , 2009Moya et al, 2007;Brito et al, 2009;Araújo et al, 2010a, b;Moreira et al, 2010;Oliveira et al, 2010). In bees, the most detailed studies are restricted to the Apidae (Lino-Neto et al, 2000b;Zama et al, 2001Zama et al, , 2004Zama et al, , 2005aBáo et al, 2004;Araújo et al, 2005c;Badke et al, 2005;Fiorillo et al, 2009), some Halictidae (Fiorillo et al, 2005), Megachilidae and Andrenidae (Quicke et al, 1992).…”
