“…Eight subfamilies are currently recognized in Geometridae (Sihvonen et al, 2011). Several recent molecular and morphological studies have attempted to confirm the monophyly or clarify the taxonomy of most of these groups, for instance: Sterrhinae (Holloway, 1997; Hausmann, 2004; Sihvonen & Kaila, 2004; Õunap, Viidalepp & Saarma, 2008), Larentiinae (Holloway, 1997; Mironov, 2003; Viidalepp, 2006, 2011; Hausmann & Viidalepp, 2012; Õunap, Viidalepp & Truuverk, 2016), Desmobathrinae (Holloway, 1996; Hausmann, 2001), Archiearinae (Hausmann, 2001; Young, 2006), Oenochrominae (Holloway, 1996; Scoble & Edwards, 1990; Cook & Scoble, 1992; Hausmann, 2001; Young, 2006), Geometrinae (Cook et al, 1994; Pitkin, 1996; Hausmann, 2001; Ban et al, 2018), Orthostixinae (Holloway, 1997) and Ennominae (Holloway, 1994; Pitkin, 2002; Beljaev, 2006; Young, 2006; Wahlberg et al, 2010; Õunap et al, 2011; Skou & Sihvonen, 2015; Sihvonen, Staude & Mutanen, 2015), but questions remain. An important shortcoming is that our understanding of geometrid systematics is biased towards the long-studied European fauna, whereas the highest diversity of this family is in the tropics, which are still largely unexplored (Brehm et al, 2016).…”
