In his introduction to the above-mentioned publication (Bruynseels, 1975), J.K. Bruynseels expresses his special gratitude to me for my “multiple advice and help”. The author forgets, however, to add that he did not follow my principal advice: to study more material and not to publish his new species Cymbium caputvelatum. Although the author asked me to be his mentor, he never submitted any manuscript of his text to me. After having read Bruynseels’s article, I believe it necessary to give some rectification in order to avoid possible confusion caused by this revision.
