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.).
