Note: This species seems to be extremely variable in exosclettal characters. The ventral sexual characters of the males from various localities of the vaste areal of the species are remarkably different. There are males, which have a sharp median carina on metasternum (fig. 48), other do not. All males have a similar aedeagus. Remarkable in this species is also the shape of the paraglossa, which seems to belong to a hitherto undescribed type (fig. 47). Probably this species has to be splitted into several species of subspecies.
