As shown by the short setae of the hind coxa, the robust posterior part of the first metasomal tergite and frequently present moon-shaped yellow patch of the clypeus in females of both E. punctaticlypeus and E. lunulatus , the first one could be considered a large form of the latter. We recognise E. punctaticlypeus as a separate species because of the dark brown antennal hook of the males (yellow in E. lunulatus ), differences in sculpture (but part may be the result of the larger body size) and the presence of a pair of large yellow spots on the mesoscutum of females (but the latter is variable in E. papillarius and this may be also the case in this species). Distribution. Examined specimens are from Spain, France, Bulgaria, and Turkey. This rarely collected species is also reported from Albania, Italy (type series), Greece and Ukraine (Crimea).
