Etymology: weitzmani: weiztmani is an eponym for Stanley H. Weiztman, in recognition of his many contributions to Neotropical ichthyology, particularly his work on the ichthyofauna of southern Brazil and the taxonomy of the genus Jenynsia.
Eponymy: Reverend Leonard Jenyns (1800–1893) was a clergyman and amateur naturalist. [...] Dr Stanley Howard Weitzman (1927–2017) was an American ichthyologist who was Research Scientist Emeritus, Division of Fishes, Department of Invertebrate Zoology, at the National Museum of Natural History, Smithsonian and a professor at George [...] (Ref. 128868), visit book page.
