Aphthona coerulescens Weise, 1889

There is disagreement whether the original spelling "czwalinae" should be emended to "czwalinai". Weise (1888) has evidently derived the species-group name from the family name of Mr. Czwalina, because he writes in the original description: "Von Herrn Czwalina aus Königsberg auf Euphorbia esula L. bei Oliva, in der Nähe Danzig´s entdeckt" (translation: "Discovered on Euphorbia esula L. near Oliwa, in the vicinity of Gdansk by Mr. Czwalina from Kaliningrad "). Thus, if one assumes that Weise (1888) intended to acknowledge the discoverer Mr. Czwalina by dedicating the species-group name to him, the correct spelling should indeed be the masculine genitive "czwalinai". On the other hand, Weise (1888) did not explicitly write that he dedicated the name to Mr. Czwalina himself. He could have thanked Mr. Czwalina by dedicating the species-group name to Mr. Czwalina´s wife, daughter or mother. Thus, if Weise (1888) had written "I dedicate this species to the discoverer Mr. Czwalina", then this would be clear evidence for an incorrect original spelling in the sense of Article 32.5. of the Code. Because this clear evidence is lacking I suggest that the criteria of Article 32.5. are not met and the original spelling "czwalinae" must be retained.
