Bellura vulnifica. Ongoing research on the Arzamini by Eric L. Quinter shows that Bellura vulnifica, stat. rev., (= Arzama diffusa, syn. rev., = Arzama melanopyga, syn. rev.) is not a synonym of Bellura gortynoides but should be treated as a valid species. B. gortynoides is of a brighter yellow color throughout its range, with little or no tendency to become darker northward. B. vulnifica feeds in Nymphaea, whereas B. gortynoides eats Nuphar. The type material of B. vulnifica is apparently lost, so its identity was determined from the original description. The types of the other three species were examined. [Contributed by Eric L.
