  Leo Zehntner (19 December 1864 in Reigoldswil – 3 April 1961 in Liestal) was a Swiss naturalist.
  
  ## Biography
  
  He studied natural sciences in Basel and Bern, and following graduation (1890), he worked as an assistant to entomologist Henri Louis Frédéric de Saussure in Geneva. In 1894 he began work as a zoologist at the Pasuruan inspection station on Java, where he dealt with pests that plagued sugar cane plantations. In 1901 in Salatiga (Java) he opened an inspection station for cacao cultivation.
  
  From 1906 to 1918 he served as director of the agricultural institute for the State of Bahia in Brazil, during which, he is credited with the discovery of eight new plant species. In 1920 he returned to Europe, and from 1926 to 1941, he served as mayor of the town of Reigoldswil.
  
  The Malagasy millipede genus Zehntnerobolus commemorates his name, as does taxa with the specific epithet of zehntneri, an example being the cactus species Quiabentia zehntneri.
