Oxypoda haemorrhoa (MANNERHEIM 1830)

Comment: Like O. flavicornis , O. haemorrhoa is extremely variable. In particular, this is true of the shape of the antennae, which may occasionally approach the condition in O. flavicornis . In one locality in northern Turkey, both species were collected together. Based on external characters alone, it was virtually impossible to distinguish them. A reliable identification, however, is unproblematic based on the sexual characters, especially the shape and internal structures of the median lobe of the aedeagus. For an illustration of the aedeagus of O. haemorrhoa see ASSING (2008). In one Moroccan locality, O. haemorrhoa was collected together with the similar O. imminuta .
