Olinga is a genus of caddisflies belonging to the family Oeconesidae. The genus was described by Robert McLachlan in 1868, revising the genus name in 1894. All known species of Olinga are endemic to New Zealand.
Robert McLachlan originally described the genus in 1868 under the name Olinx, naming Olinx feredayi as the type species. 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 been using Olinx for another genus; which authors had been rendering as Olina since 1866. The genus was monotypic until 1958, when Keith Arthur John Wise described Olinga fumosa.
Phylogenetic analysis indicates that Olinga forms a clade with the genera Alloecentrella, Beraeoptera, Confluens, Pycnocentria and Pycnocentrodes.[1]
The genus is found in New Zealand.
