Robert McLachlan originally described the genus in 1868 under the name Olinx, naming Olinx feredayi as the type species.[3][4] In 1894 he revised the name of the genus as Olinga, describing this change as "necessary, and under rather peculiar circumstances" as German entomologist Arnold Förster had proposed Olynx for another genus in 1856, which other authors had been rendering as Olinx since 1858, thus leading McLachlan to erroneously conclude that his name was preoccupied.[5] The genus was monotypic until 1958, when Keith Arthur John Wise described Olinga fumosa.[6]
