Diagnosis

Its characteristically short valvula 3 is the best morphological character for recognizing E. schlueteri , but this distinction is not always clear with respect to the other species with similar colouration (particularly E. striata ). The unusual host ( Vaccinium ) for the Euura histrio group and nuclear data additionally support the distinctness of the species. Males might not be clearly distinguishable from most of the other species.

Genetics

COI

Based on 10 specimens, maximum within-species distance is 0.76% and the nearest neighbours, diverging by a minimum of 0%, are Euura rufa , E. striata , E. stordalensis , E. hartigi , and E. histrio .

Nuclear

Based on 8 specimens, maximum within-species distance is 0.28% (0.3% based on haplotypes of individual females). The nearest neighbour, diverging by a minimum of 0.37%, is Euura striata .

Distribution and material examined

Palaearctic. Specimens studied are from Finland, and Sweden.
