D i s t r i b u t i o n: at present uncertain, due to confusion until recently with both X. pedissequum and X.stackelbergi ,but known fromAndorra, the Czech Republic, France, Germany, Greece, Hungary, Italy, Montenegro, the Netherlands, Norway, Poland, Portugal, Europe- an Russia, Serbia, the Slovak Republic, Slovenia, Spain, Sweden, Switzerland;Transcaucasia (the Republic of Georgia) ( Belcari et al., 1995; Doczkal et al., 2002; De Groot & Govedič, 2008; Mielczarek, 2009 –2020; Tóth, 2011; Van Eck, 2011; Van Steenis, 2011; Ssymank, 2012; Van Steenis et al., 2015; Ricarte & Marcos-García, 2017; Nedeljković et al., 2018; Speight et al., 2018; Prokhorov, 2019; Van Steenis et al., 2019; Mengual et al., 2020; Speight, 2020; Wakkie, 2020); Ukraine (first record).

Diagnosis. Within the genus Xanthogramma , X. dives , X. pedissequum and X. stackelbergi are very similar in appearance. They share the following characters: tergite 2 wider than long; alula entirely covered in microtrichia; eye pilosity very sparse, shorter than the diameter of the anterior ocellus; hind femora black on the apical fourth. Xanthogramm adives can be easily separated from X. pedissequum by the thorax with more than two yellow maculae laterally (in X. pedissequum , thorax with one or two yellow maculae laterally). From the most similar X. stackelbergi ( figs 66, 67 View Figs 64–67 ), both sexes of X. dives can be distinguished by wing cells r 1 and r 2+3 darkened in the apical part ( figs 64, 65 View Figs 64–67 ) (in X. stackelbergi , wing cells r 1 and r 2+3 hyaline in the apical part, as on figs 66, 67 View Figs 64–67 ). These characters are based on Nedeljković et al. (2018). Additionally, X. dives female differs from X. stackelbergi by a black median vitta on the frons that usually expands towards the lunule ( fig. 65 View Figs 64–67 ) (in X. stackelbergi , a black median vitta on the frons usually tapers towards the lunule, as on fig. 67 View Figs 64–67 ) (according Speight & Sarthou, 2017).

Note. Until recently, X. dives was erroneously confused with the two similar species X. pedissequum (Harris, 1776) and X. stackelbergi Violovitsh, 1975 , and this taxon was not included in the most of European species lists before Speight & Sommaggio (2010), who designated the X. dives lectotype.
