Merodon analis Meigen, 1822

Some authors (e.g., Aistleitner et al. 2020; Franz 1989; Röder 2001) report Merodon constans (Rossi, 1794) from Austria. Vujić et al. (2020a) showed that two species in Central and south-eastern Europe have been referred to by authors under this name. Distribution and morphological characters give clear evidence to separate these two species. Merodon analis (former M. haemorrhoidalis Sack, 1913 ) occurs in Central Europe and northern Italy, Merodon constans occurs in the Mediterranean part of south-eastern Europe. Therefore, we assume that all records of M. constans formerly published for Austria refer to M. analis . Our thesis is supported by Ante Vujić, who studied many specimens from Austria but could not find any M. constans until now (Ante Vujić pers. comm.).
