Etymology: levidorsa: Specific name refers to the absence of scales along the predorsal median region, thus the smooth predorsal surface (laevis = smooth; dorsum = back).
Eponymy: Dr William J Moenkhaus (1871–1947) was an American geneticist and ichthyologist who became Professor of Physiology at Indiana University Medical School (1904–1941), where he was Eigenmann’s colleague. [...] (Ref. 128868), visit book page.
