Remarks

Huldén (1985) described and separated this species from L. bradycelli , but now there is little doubt that L. eubradycelli and L. bradycelli are conspecific. Because L. eubradycelli was legitimately described before L. bradycelli it has priority according to Code rules. This is a variable species, extremely common in Denmark, perhaps a collective species, including some undescribed taxa ( De Kesel 1997).
