Abstract

We studied 105 genitalia of mostly Finnish male Coleophora vacciniella Herrich-Schäffer, 1861, in order to inspect the variation in certain features: the number of chitinous teeth on the dorsal side of the phallotheca, the number of spines at the distal end of it, and the number of cornuti in the vesica. All of the parameters were close to a normal distribution, which did not coincide with our original idea of splitting this species complex into two or even more species. On the contrary, we had to synonymise C. betulaenanae Klimesh, 1958, with C. vacciniella, as we could not find reasonable differences between them.
