Ecnomina is a genus of caddisflies belonging to the family Ecnomidae.[1] The genus was first recognised by Douglas Eric Kimmins in 1953.[2]
Kimmins placed this genus in the family Ecnomidae due to the evidence of tibial spurs and the absence of fork number 1 in the anterior wing. He named Ecnomina spinosa as the type species.[2]
Almost all species of Ecnomina are endemic to Australia, except for Ecnomina zealandica from New Zealand. One species from New Caledonia was previously identified as Ecnomina kavinia, but has since been identified as a species of Agmina.
