(NA) / = Mt Roraima Venezuela ? (EO) / = Mt Roraima Guyana ?]) Distribution. Brazil : Evans and Smith 2009: 246 . Other: Frey 1970: 141 (see note). Note. Frey (1970: 141) gives as the type locality of Isonychus striolatus only Mt. Roraima, which is the tristate border point of Guyana , Brazil and Venezuela . Evans and Smith (2009: 246) place the location in Brazil . However, only about five percent of Mt. Roraima is within Brazil , while about 10 and 85 percent is within the territories of, respectively, Guyana and Venezuela . The actual type locality may be in either one of those countries and might be revealed by studying the diaries of the expedition on which the type specimens were found.
