Sterrhinae is a large subfamily of geometer moths (family Geometridae) with some 3,000 described species, with more than half belonging to the taxonomically difficult, very diverse genera, Idaea and Scopula (Hausmann, 2004; Sihvonen, 2005). This subfamily was described by Edward Meyrick in 1892. They are the most diverse in the tropics with the number of species decreasing with increasing latitude and elevation (Scoble et al., 1995; Hausmann, 2001, 2004; Brehm & Fiedler, 2003).
